FOREWORD
Chinook salmon are an icon of the Pacific
Northwest and a vital cultural, economic, and
environmental resource for our reqion. Salmon
disappearing from our local waters would alter the
fabric of our local communities and is an outcome
we are not willing to accept. For the past 10 years,
and the foreseeable future, the salmon recovery
effort in the Lake Washington/Cedar/Sammamish
Watershed (a.k.a., Water Resource Inventory
Area [WRIA] 8) will continue working to keep
salmon in our local streams. The WRIA 8 Chinook
Salmon Recovery Council is an example of local
governments working together regionally to deal
with a problem that if not addressed will have
long-term, wide-ranging consequences. Without
increased habitat protection and restoration, as
well as greater public awareness and support, we
risk losing these valuable fish.
When the federal government listed Puget
Sound Chinook salmon as threatened under
the Endangered Species Act in 1999, local
governments in WRIA 8 banded together to
address the listing through a coordinated,
bottom -up approach. Since 2000, the WRIA 8
Salmon Recovery Council, comprised of 28 local
government partners and community groups, state
and federal agencies, businesses, and citizens,
has worked to implement the WRIA 8 Chinook
Salmon Conservation Plan (Plan), driven by the
shared goal of recovering sustainable, harvestable
populations of Chinook salmon. This collaborative
effort demonstrates the power of working together
toward a common vision, investing in a cause
that will not only benefit the region's salmon
populations, but will also improve the quality of life
for all people and wildlife in our watershed.
After more than 10 years of implementing the
WRIA 8 Plan, we can say that we have made great
headway, and our partnership remains strong. We
have helped protect more than 1,500 acres of land,
over 300 acres of floodplain, and nearly 12 miles of
streambank. We have helped restore over 75 acres
of floodplain, more than 325 acres of riparian area,
and over a mile of lakeshore. We have removed
invasive species from more than 500 acres of
riparian areas. This is a great foundation from
which to continue and accelerate our efforts on
habitat protection and restoration.
However, salmon recovery is a long-term endeavor,
and Chinook salmon populations remain far
short of our goal of sustainable runs that enable
tribal and recreational fishing. Over a century
of development and modification in our region
degraded salmon habitat and reduced populations
to critically low levels. It will take us time and
investment to restore our streams and rivers and
recover salmon. Updating the Plan is an important
step in keeping salmon recovery on track. Through
this Plan Update, we set ambitious new habitat
goals and developed a set of recovery strategies
to guide implementation and ensure our salmon
recovery efforts continue to be based on the most
recent science, are informed by lessons learned,
and are using limited resources wisely. This Plan
Update also tells our salmon recovery story and
explains to our partners, the public, and decision
makers what is still needed to recover Chinook
salmon.
As the most populous watershed in the state, WRIA
8 is the proving ground for whether salmon and
people can live together. The 28 local government
partners in WRIA 8 remain committed to recovering
Chinook salmon. We serve as a model for how
communities can effectively coordinate and rally
around a shared natural resource issue. By continuing to work together, even as our region grows, we can
continue to have both a vibrant local economy and a healthy watershed with strong salmon runs returning o
each fall. N
Working to recover salmon is about more than salmon — it is fundamentally about caring for our home and u,
making our communities sustainable for the long-term. The strategies and actions called for in this Plan
will protect and restore salmon habitat, but they will also improve water quality, reduce flood hazards, a
protect open space, improve stormwater management, sustain and improve our quality of life, and promote
a proud legacy of stewardship for future generations. By taking action to recover Chinook salmon, we w
are taking a stand that extinction is not an option, that we want a healthy environment where we live, o
that meeting tribal treaty rights is imperative, and that future generations will continue to witness salmon
returning to local streams.
c
m
On behalf of the WRIA 8 Salmon Recovery Council, we are pleased to share this update to the WRIA 8 a
Chinook Salmon Conservation Plan, and we strongly encourage everyone interested in salmon recovery o
and watershed health to assist in implementing this plan.

among 28 local government partners, as well as
grant funding from Washington State's Puget Sound
Acquisition and Restoration fund and the Aquatic
Lands Enhancement Account through a state
legislative allocation to Puget Sound Partnership.
EXECUTIVE SUMMARY
This document updates the Lake Washington/
Cedar/Sammamish Watershed Chinook Salmon
Conservation Plan (2005 Plan; WRIA 8 Steering
Committee, 2005). Since 2000, Lake Washington/
Cedar/Sammamish Watershed (a.k.a. Water
Resource Inventory Area [WRIA] 8) partners
have worked together to improve conditions
for threatened Chinook salmon, with the goal of
bringing naturally -produced Chinook salmon back
to sustainable, harvestable levels. While the Plan
focuses on recovering Chinook salmon, actions
taken to improve conditions for Chinook also
improve conditions for other salmon species and
support improving overall watershed health.
The 2017 WRIA 8 Chinook Salmon Conservation
Plan (2017 Plan) updates the 2005 Plan by drawing
on current science to develop quantitative habitat
goals for Chinook salmon, evaluate the negative
impacts (or pressures) on Chinook salmon, update
salmon recovery strategies to identify actions that
address the highest priority pressures on salmon,
and produce a Monitoring and Assessment
Plan (MAP).
The 2017 Plan is an addendum to the 2005 Plan,
but is also intended to serve as a stand-alone
document. As an addendum, the 2017 Plan
continues themes and content discussed in the
2005 Plan, provides information learned during
the first 10 years of implementation, includes new
habitat goals, and identifies new and updated
strategies to meet salmon recovery goals. The
20 updated strategies are a valuable new tool to
direct our work addressing the key factors limiting
salmon recovery in our watershed. They are
outlined in Section 4 of this document and spelled
out in detail in Appendix E.
Over the past 10 years, we have learned more
about the impacts humans have on Chinook
salmon survival through empirical scientific
research, studies, and formal and informal
monitoring of implemented projects. While the
2005 Plan included measurable salmon population
recovery goals, there were no measurable goals
for habitat restoration. The 2017 Plan uses recent
habitat monitoring efforts that establish baseline
conditions to develop near -term (2025) and long-
term (2055) quantifiable habitat recovery goals.
To produce a plan to achieve these goals, a
conceptual model was developed to identify key
life stages and important habitats that may limit
Chinook salmon recovery. Human impacts that
exert pressures on Chinook salmon and their
habitat were evaluated for each life stage and
geographic area of the watershed. This work
formed the basis for developing the 20 recovery
strategies to improve conditions that support
Chinook salmon in WRIA 8.
One of the primary gaps identified in the 2005 Plan
was the lack of methodology to measure progress
towards the desired future status of habitat. While
we have learned much from monitoring efforts to
date, developing the MAP (Appendix A) allows
us to better assess our progress and correct our
course as we protect and restore salmon habitats
and ecosystem processes. The MAP guides project
sponsors in monitoring and reporting the progress
of habitat restoration projects towards habitat and
salmon recovery.

PLAN UPDATE CONTEXT
This document updates the Lake Washington/
Cedar/Sammamish Watershed Chinook Salmon
Conservation Plan (2005 Plan; WRIA 8 Steering
Committee, 2005). Since 2000, Lake Washington/
Cedar/Sammamish Watershed (a.k.a. Water
Resource Inventory Area [WRIA] 8) partners
have worked together to improve conditions
for threatened Chinook salmon, with the goal of
bringing naturally -produced Chinook salmon back
to sustainable, harvestable levels.
Concerned about the need to protect and restore
Chinook salmon habitat for future generations and
to maintain local control over recovery decisions
and implementation, 27 local governments in WRIA
8, including King and Snohomish counties and
25 cities, signed an interlocal agreement (ILA) in
2001 to jointly fund the development of the 2005
Plan. The 2005 Plan was created with input from
numerous stakeholders to provide a science -
based roadmap for protecting and restoring
spawning, rearing, and migratory habitat for
Chinook salmon.
When the WRIA 8 Salmon Recovery Council
adopted the 2005 Plan, they established
an initial 10-year implementation
period and called for the
plan to be reviewed
and updated
after that

time. After 10 years, we have learned much about
where more work is needed. The 2017 WRIA 8
Chinook Salmon Conservation Plan (2017 Plan)
updates the 2005 Plan with new information and
lessons learned over the last decade, and includes
refined strategies and goals for the future. The full
process for updating the 2017 Plan with Salmon
Recovery Council input and approval is described
in Appendix B.
In 2015, 28 local government partners in the
watershed (the Town of Woodway joined the
original 27 partners in 2014) renewed the ILA,
recommitting themselves to coordinated salmon
recovery for another 10 years. In so doing,
partners recognized the habitat protection and
restoration progress made over the past decade,
the resulting benefits to local communities,
and the efficiency of working collectively to make
the watershed a place where salmon and
people can live together.
RECOVERY CONTEXT
The Lake Washington/Cedar/Sammamish
Watershed (WRIA 8), located in western
Washington, comprises 692 square miles and
includes two major river systems (the Cedar and
Sammamish rivers) and three large lakes (Union,
Washington, and Sammamish). It also includes
the marine nearshore and numerous smaller
sub -basins that drain directly to Puget Sound
from West Point in the City of Seattle northward
to Elliott Point in the City of Mukilteo. WRIA 8 is
located predominantly in western King County
and about 15 percent of the land area extends
northward into Snohomish County. Over 53
percent of the marine shoreline is located within
Snohomish County (Figure 1). A large portion of
the upper Cedar River watershed is the municipal
drinking water supply for the City of Seattle,
and is managed under a Habitat Conservation
Plan (HCP). Tribal treaty areas in WRIA 8 include
usual and accustomed fishing places of the
Muckleshoot, Snoqualmie, Tulalip, and Suquamish
tribes. The human population of the watershed is
approximately 1.4 million.
Historically, the Lake Washington watershed
drained south to the Black and Duwamish rivers.
In 1916, the U.S. Army Corps of Engineers (USACE)
constructed the Hiram M. Chittenden (a.k.a.
Ballard) Locks (Locks) and excavated the Ship
Canal to conned the Union Bay area in Lake
Washington with Salmon Bay in Puget Sound. The
surface of Lake Washington dropped 9 feet and
exposed previously inundated shallow -water areas,
decreasing the lake shoreline by 12.8 percent and
draining many of the lake's wetlands. The decrease
in lake elevation disconnected Lake Washington
from the Duwamish River, and the Cedar River —
which previously flowed into the Duwamish River
via the Black River —was permanently rerouted to
Lake Washington. As most of the Black River dried
up and became impassable, salmon populations
were forced to find a new route to their natal
streams. The Sammamish River, which historically
had a meandering channel through a large wetland
complex, was also heavily modified, straightened,
and drained in the early to mid-1900s to reduce
flooding and support agricultural production in
the Sammamish Valley. In subsequent years,
salmon habitat was further impaired as upland and
shoreline development removed more shallow -
water habitat, reduced channel complexity in rivers
and streams, and reduced forest cover along lake
and channel shorelines. Today, all Chinook salmon
enter and exit the watershed through the Ballard
Locks and its associated fish passage facilities.
An estimated 31 populations of Chinook salmon
once existed in Puget Sound. Annually, nearly
700,000 adults returned to Puget Sound
watersheds to spawn. Since the late 1800s and
early 1900s, human activities such as logging,
overfishing, water withdrawals, and land
development have caused the numbers of Chinook
salmon to plummet to less than 10 percent of their
historic levels (Figure 2). Nine populations have
gone extinct, leaving only 22 populations in the
Puget Sound. This drastic decline prompted the
federal government to list Puget Sound Chinook
salmon as threatened under the Endangered
Species Ad in 1999.

WRIA 8 is home to two of the 22 Chinook salmon
populations in Puget Sound: the Cedar population
(Cedar River and tributaries) and the Sammamish
population (Sammamish River, North Creek,
Little Bear Creek, Bear/Cottage Lake Creek,
Issaquah Creek, Kelsey Creek). Focusing on two
populations reflects a change since adoption of
the 2005 Plan. Originally, lacking certainty about
genetic differences between populations, salmon
recovery partners took a precautionary approach
that identified three distinct Chinook salmon
populations in WRIA 8. Genetic analyses performed
after the 2005 Plan indicated that a two -population
approach (Cedar River and Sammamish River
populations) was appropriate. This approach was
adopted by the WRIA 8 Salmon Recovery Council
in 2010.
The contribution of WRIA 8 partners to the overall
goal of increasing WRIA 8 natural -origin Chinook
salmon to sustainable and harvestable levels is to
protect high -quality habitat, as well as to reduce
existing pressures and restore additional habitat
needed by salmon at specific life history stages
in the watershed. To prioritize implementation of
restoration strategies, the watershed has been
classified into functional "tiers" based on watershed
condition and fish use (Figure 1). Tier 1 areas
are the highest priority habitats for protection/
restoration, and include primary spawning areas,
as well as migratory and rearing corridors. The
Cedar and Sammamish rivers, Bear and Issaquah
creeks, shores of lakes Sammamish, Union, and
Washington (including the Ship Canal), and the
marine nearshore (including bluff -backed beaches
and pocket estuaries) are classified as Tier 1. The
Cedar River is considered the highest priority Tier
1 area because it includes spawning and rearing
areas for the Cedar population, which supports the
largest number of natural -origin Chinook salmon
in the watershed. With its tributaries, it is also the
sole spawning area for the Cedar population. The
marine nearshore is a Tier 1 area because it is
important as migratory and rearing habitat for
WRIA 8 Chinook populations and those from other
Puget Sound watersheds.
Tier 2 areas are a secondary priority and include
areas less frequently used by Chinook salmon for
spawning, but that contribute to the overall spatial
diversity of salmon populations in the watershed.
Tier 2 systems include North, Little Bear, Kelsey,
and Evans creeks. Upland areas associated
with Tier 1 and Tier 2 streams assume the tier
designation for the waterbody the upland area
supports.
Tier 3 areas (all areas not Tier 1 or Tier 2) contain
streams that are infrequently or never used
by Chinook salmon, but are still important for
other species of salmon and resident fish, water
quality, flow management, and overall watershed
health. Coal and May creeks were classified as
Tier 3 streams in the 2005 Plan. Recently, these
creeks have experienced an increase in use by
spawning Chinook salmon, and contain areas
with somewhat higher quality habitat compared
to some other Tier 2 areas. The WRIA 8 Technical
Committee (TC) plans to monitor their status and
to consider upgrading these streams to Tier 2 if
adult returns continue to increase.
In addition to prioritizing geographic areas by
tiers, the 2017 Plan further prioritizes actions by
life stage, using an updated conceptual model
developed by the WRIA 8 TC during the 2017
Plan update process. This conceptual model is
described in more detail in Section 2.2.
2. RECOVERY GOALS
As part of the 2005 Plan update process, the WRIA 8 Technical
Committee (TC) reviewed the Chinook salmon population recovery
goals established in the 2005 Plan and determined that they remain
appropriate and relevant. Upon the recommendation of the TC, the
WRIA 8 Salmon Recovery Council approved carrying them forward in
the 2017 Plan.
Noting that the 2005 Plan did not include quantifiable habitat goals,
the TC used an assessment of pressures on Chinook salmon, a
new conceptual model, existing monitoring data, limiting factor
assessments, and available scientific studies to develop and articulate
a focused set of near -term (2025) and long-term (2055) Chinook
salmon habitat goals. These habitat goals provide targets for the most
important Chinook salmon habitat elements in the watershed, and
give us a roadmap for measuring progress.
CHINOOK SALMON RECOVERY GOALS
Chinook salmon population recovery goals were determined
using the Viable Salmonid Population (VSP) concept and the
recommendations identified in WRIA 8's "H-Integration" process
to address impacts from habitat degradation, hatchery production,
and harvest. A "viable" population is one that has a negligible risk of
extinction in its native habitat over a 100-year time frame. Recovery
goals are set for both a near -term (2025) and a long-term (2055) time
frame for each VSP parameter to support sustainable Chinook salmon
populations (Table 1). The 2025 and 2055 goals described for the
Chinook salmon recovery goals in this section are the same as the
short-term and long-term goals from the 2005 Plan.
The 2005 Plan included Chinook salmon population recovery
goals that are based on recovery planning targets provided by the
Washington Department of Fish and Wildlife (WDFW) and the National
Oceanic and Atmospheric Administration's (NOAA) Population
Viability Analysis, which the TC further elaborated in 2009 as part
of the H-Integration process. The TC reviewed these goals as part
of updating the 2005 Plan, and recommended no changes for the
2017 Plan, which the Salmon Recovery Council approved. For more
information on the Chinook salmon population recovery goals, see
Chapter 3 of the 2005 Plan.
Adult spawner ("fish -in") and juvenile outmigration ("fish -out")
monitoring has occurred in the watershed since 1998, at significant
expense to watershed partners. The TC recognizes the value of these
data and recommends continuing this work. However, the TC notes
that future priorities may require directing limited monitoring funds
toward other priorities over the next 10-year implementation cycle.

HABITAT GOALS
The relationships between habitat conditions and
Chinook salmon growth and survival are known
to be multifaceted and complex. They operate at
many spatial and temporal scales. The response
of Chinook salmon populations to even large-scale
habitat improvements may not be detectable for
years, and may be confounded by improvements
or declines elsewhere in the watershed or in the
marine environment. Nevertheless, known linkages
exist between freshwater habitat conditions and
salmon, supported by decades of
scientific research.
During the 2017 Plan update process, the TC
reviewed new information about Chinook salmon
needs and limiting factors in WRIA 8. This review
culminated in a conceptual life stage model of
WRIA 8 Chinook salmon that considers the habitat
needs and pressures facing Chinook salmon at
each specific time and place in their lifecycle.
The conceptual model allowed the TC to rank
the pressures affecting Chinook salmon in the
watershed, thereby helping ensure that strategies
were developed to address the most pressing
issues. This process allowed the TC to focus
protection and recovery recommendations where
they will be most effective and cost-efficient.
WRIA 8 conceptual life -stage model
Chinook salmon occupy different and unique
habitats at each stage of their lives. Each of these
habitat types becomes significant to salmon for
the specific periods it is occupied (or traversed)
by Chinook salmon. Environmental conditions
vary across space and time; stresses vary in
their significance by geography, season, and life
stage. The life stage conceptual model for WRIA
8 Chinook salmon (Figure 3) attempts to describe
these local stresses and illustrate the factors with
the most important impacts. The following section
summarizes the key factors affecting each life
stage at the most significant places and times.
More information can be found online at http;//
www.goviink.org/watersheds/8/reports/default.

Adult migration occurs from June through
September from Salmon Bay through the Ballard
Locks and Ship Canal to Lake Washington,
and from Lake Washington either north to the
Sammamish River and its tributaries, or south to
the Cedar River or south Lake Washington tributary
streams (Kelsey, May and Coal creeks). Significant
stresses identified for adult migrants include
thermal and dissolved oxygen barriers at the Locks
and Ship Canal, and physical passage through the
Locks and fish ladder. The Sammamish River can
pose significant thermal stress to Chinook salmon
returning to Bear/Cottage Lake and Issaquah
creeks, as well as to Chinook salmon returning
to the Issaquah Salmon Hatchery. Lethal and
sublethal temperatures in the Ship Canal and
Sammamish River during adult migration are
considered a key constraint on recovery.
Harvest in terminal or freshwater areas (including
bycatch) is currently minimal, and is managed to
protect Cedar River Chinook salmon as stipulated
in the Puget Sound Chinook Harvest Management
Plan (Puget Sound Indian Tribes and WDFW, 2010).
Stream flows on the Cedar River are managed
by Seattle Public Utilities to support fall migration
and spawning needs. Elsewhere, low flows early
in the migration period could potentially impede
migration. The sockeye broodstock collection
facility on the lower Cedar River has the potential
to delay passage and alter spawning patterns
(facility is monitored and managed to minimize
delays and is undergoing redesign). Predation on
migrating adults occurs at the Locks, but is not

consistently significant. Disease or parasites on
Chinook salmon do not appear to be a significant
issue at this time.
Spawning in WRIA 8 occurs from September
through November in the Cedar River, Bear/
Cottage Lake Creek, Issaquah Creek (below and
above the Issaquah Salmon Hatchery), Little Bear
Creek, North Creek, and Kelsey Creek. May and
Coal creeks and a few other streams in the basin
also see intermittent use by small numbers of
Chinook salmon. Monitoring on the Cedar River
and on Bear/Cottage Lake Creek indicates that
these streams have sufficient spawning habitat
at current abundance levels. Limitations in other
creeks are unknown but are assumed to be
present inside the Urban Growth Area (UGA).
Potential spawning stresses include habitat
limitations (gravel quantity and quality, inadequate
cover), hatchery interactions, and low streamflow
and high temperatures early in the spawning
season. In addition, disturbance or harassment
by humans or their pets, or human infrastructure
(e.g., artificial light) could affect spawning success,
especially in urban areas.
Incubation and emergence occurs from
September through March in the Cedar River,
Bear/Cottage Lake Creek, Issaquah Creek (below
and above the hatchery), Little Bear Creek, North
Creek, and Kelsey Creek. Potential stresses
include habitat limitations through excessive fine
sediments, abnormally high or low streamflow,
high temperature, and possible water quality
concerns, especially during early fall freshets
(urban stormwater has been shown to affect
salmon embryo development). Monitoring on
Cedar River and Bear Creek indicates those areas
are not limited at this life history stage at current
abundance levels (WRIA 8 TC, unpublished data).
Habitat quality/quantity limitations on other creeks
are unknown but likely high, except perhaps
upper Issaquah Creek where human impacts are
lower. Streamflow on the Cedar River is regulated
to support Chinook salmon incubation through
an HCP, and is managed during redd incubation
to avoid, if possible, redd scour due to flows
above about 2,200 cfs. Flow management on the
Cedar River also supplements minimum flows to
prevent redd dewatering during low flow periods.
It is important to note that flow management can
be limited due to the relatively small size of the
water supply dams on the Cedar River, which
were not designed as flood control facilitates.
Elsewhere, high- or low -flow events may affect
success through scouring or dewatering redds.
Temperature during incubation influences time of
emergence — warmer temperatures speed embryo
development and result in earlier emergence
dates, which could affect survival if fry emerge
before prey or during high winter flows.
Stream rearing occurs from January through July,
and a very small fraction of the population remains
in the system as yearlings. Stream rearing occurs
in the Cedar River, Bear/Cottage Lake Creek,
Issaquah Creek (below and above the hatchery),
Little Bear Creek, North Creek, and Kelsey Creek.
Potential stresses include streamflow, habitat
limitations (quantity and quality of instream habitat,
cover, flood refugia, and large woody debris),
predation, prey resources, and water quality. A
key constraint on Chinook salmon recovery
in WRIA 8 is insufficient Instream rearing and
refuge habitat, due to habitat simplification, loss
of floodplains and side channels/off-channel
rearing, and lack of large woody debris. Evidence
from annual juvenile outmigrant trapping indicates
this life stage is limited in the Cedar River and
Bear/Cottage Lake Creek. It is likely that this life
stage is limited by lack of instream rearing and
refuge habitat throughout the watershed, though
little data exist on Chinook salmon productivity
in other WRIA 8 streams. (Habitat monitoring
confirms lack of quality rearing/refuge habitat.)
Streamflow issues vary from year to year. Peak
storm flows may wash fry downstream if floodplain
refuge habitat is insufficient; base flows are usually
adequate during the period that Chinook salmon
rear in the stream (although unusually low base
flows in spring 2015 could become more common
under climate change scenarios). Predation by
cutthroat trout (Oncorhynchus clarkii) and other
predators may be a factor. Prey abundance and its
potential limitation during the stream rearing stage
is unknown, although prey abundance may be
considered low in areas with low concentrations of
macroinvertebrates (as measured by the Benthic
Index of Biotic Integrity, or B-IBI). Poor water quality
may affect Chinook salmon survival in areas with
high volumes of storm runoff.
Downstream migration occurs from January
through July, with fry migrants moving downstream
from January through April, and parr migrants
moving downstream from April through July.
Potential stresses include streamflow, habitat
limitations (quantity and quality of cover), and
predation. Predation on migrating juvenile
Chinook salmon by resident trout and other fish,
including some non -natives, may present localized
bottlenecks, and is likely a key pressure at this life
stage.
Lake rearing and migration occur from January
through July, with small numbers of Chinook
salmon remaining year-round in Lake Washington
and Lake Union, either by choice or due to late -
season thermal barriers to outmigration at the
Ballard Locks, Lake Washington is a unique
feature across Puget Sound Chinook populations,
and functions much like an estuary for WRIA 8
Chinook salmon fry. Rearing in Lake Washington
begins in the southern end near the outlet of the
Cedar River (January through March) and shifts
northward toward Union Bay and the Ship Canal
in later months, as juveniles move toward eventual
outmigration (May through July). Prey resources do
not appear to be limiting. During January through
to early April, fry are shoreline -oriented and
feed primarily on chironomids in shallow waters.
Chinook salmon fry become less shoreline -oriented
and occupy deeper water as they grow and
migrate northward, and shift to Daphnia spp. as
their preferred prey after the spring phytoplankton
bloom and daphnia emergence. Information on the
behavior of naturally produced Chinook salmon in
Lake Sammamish is limited, but it is likely that fry
exhibit similar behavior.
Potential stresses during take rearing and migration
include predation, habitat limitations (quantity and
quality of refuge habitat, cover), inadequate prey
resources, high temperatures, and poor water
quality. Shoreline habitat, including stream mouths,
has greater importance at the southern ends of
Lake Washington and Lake Sammamish when

Chinook salmon are smaller; good lake shoreline
habitat is generally lacking throughout both lakes.
Early -season predation on Chinook salmon is
assumed to be focused on the southern shorelines,
with a shift northward and offshore as Chinook
salmon grow. Early -season water temperatures
likely hinder significant predation by warmwater
fish, but predation by cutthroat trout and northern
pikeminnow (Ptychocheilus oregonensis) could
affect a large proportion of the Chinook salmon
population. Recent captures of walleye (Sander
vitreus), a non-native warm -water lake fish common
to the Midwest, in both lakes raise concerns that
this low -light predator could adversely affect
overall survival rates in the future if their numbers
grow. There is little research on avian predation
in Lake Washington. Predation by fish in Lake
Washington and the Ship Canal, while not yet
adequately quantified, appears likely to be a key
constraint on juvenile rearing and migration.
Predation is likely to be exacerbated by artificial
nighttime lighting in urban areas. Poor water quality
may have sublethal effects on Chinook salmon
survival, especially near stormwater outfalls and in
the Ship Canal and Lake Union. Recent analyses
showed no evidence of polychlorinated biphenyl
(PCB) contamination of juvenile Chinook salmon
leaving the Lake Washington system, although the
issue is known to be significant elsewhere in Puget
Sound (Meador, 2013).
Migration to Puget Sound occurs from April
through August. The key geography for this life
stage includes the Lake Washington Ship Canal,
Ballard Locks, and the Salmon Bay estuary.
Potential stresses include abrupt temperature and
salinity transitions, predation, habitat limitations
(quantity and quality of refuge habitat, cover),
high temperatures, poor water quality, and lack of
prey resources (though ample zooplankton prey
are available in the inner bay just downstream of
the Locks (Simenstad et al., 2003). Predation by
warmwater predators is likely significant because
of the concentration of predators and timing of
migration. Recent surveys have documented
smallmouth bass (Micropterus dolomieu),
largemouth bass (M. salmoides), rock bass
(Ambloplites rupestris), and yellow perch (Perca
flavescens) as predators on juvenile Chinook
salmon in the Ship Canal. The Ballard Locks pose
a migration barrier hazard as exit pathways may
physically harm Chinook salmon, delay their
volitional passage, or cause other sublethal effects.
Nearshore foraging occurs primarily from April
through August in the Puget Sound nearshore, but
Chinook are found in the nearshore throughout
the year (Brennan et al., 2004). Data from beach
seining in 2001 and 2002 showed thatjuvenile
Chinook (<150mm) caught within WRIA 8's
nearshore consumed higher amounts of crab
larvae and terrestrial insects than two areas in
WRIA 9 (Brennan et al., 2004). It also showed that
as juvenile Chinook get larger than 150mm, they
predominately feed on other fish. Potential impacts
include lack of rearing habitat and disconnected
habitat, predation, lack of or competition for prey
resources, and poor water quality. Since WRIA
8 lacks a true estuary, Chinook fry tend to rear
in Lake Washington and enter Puget Sound at
approximately the same size as WRIA 8 parr
migrants. The nearshore is a shared resource that
offers regional benefits for Chinook migrating
along the shoreline from WRIA 8 as well as from
other watersheds.
Maturation (marine waters). Chinook salmon
spend 1 to 5 years in Puget Sound and the Pacific
Ocean before returning to fresh water to spawn,
with the majority of WRIA 8 Chinook salmon
returning at age 3 or 4. Shifts in ocean conditions
such as those related to El Nino and Pacific
Decadal Oscillation patterns or climate change
(e.g., ocean acidification) have been shown to
affect ocean survival rates and therefore Chinook
salmon abundance. Approximately 58 percent of
WRIA 8 adult Chinook salmon caught in marine
fisheries (1973-1985) were recovered within Puget
Sound, while 15 percent were recovered off
southwest Vancouver Island (Quinn et al., 2005).
Marine harvest of Chinook salmon is governed by
international treaty and by state, federal, and tribal
fishery managers.
HABITAT GOALS SUMMARY
During development of the 2017 Plan, the TC
developed a short list of near -term (2025) and
long-term (2055) goals (Table 2) that focus on the
key elements affecting Chinook salmon within the
watershed, as determined by scientific research
(including new and emerging scientific information),
the WRIA 8 Chinook salmon conceptual model,
and assessment of the human pressures on
Chinook salmon survival in WRIA 8 (Section 3.3).
The 2025 goals selected by the TC focus on the
most important habitat elements for conservation
and recovery of Chinook salmon in the watershed
and are based on local data, the unique constraints
placed on rivers and streams in the WRIA 8
watershed, and the pace of implementation
progress in the last 10 years. These goals are
intended to be feasible and achievable, and are
proxies for a larger set of habitat processes that o
the TC hypothesizes will be improved if these —
goals are met. The 2055 goals represent desired
future conditions, which in some cases are a o
qualitative description rather than a quantitative D
measure. The WRIA 8 Salmon Recovery Council a
approved the goals during development of the }
2017 Plan. g
Monitoring is necessary to track progress towards
achieving these goals. To align with other planning M
horizons and remain ecologically meaningful, we C
recommend that adaptive management course
corrections occur in 5-year intervals, at which
time the goals will be assessed and adjusted as
necessary, and the next adaptive management
planning horizon will be set. The WRIA 8 TC will
oversee monitoring efforts in the intervening
periods and recommend changes if warranted by
interim results. (see Appendix A: Monitoring and
Assessment Plan)

Table 2. WRIA 8 Habitat Goals
In 2015, WRIA 8 hosted a technical forum
assembling fisheries scientists and technical
experts on salmon recovery in the watershed.
Participants proposed the following priority -
level rankings of limiting factors to recovery.
These constitute an outline for a prioritized list
of research and data needs to advance recovery
and support implementation of the 2017 Plan.
(A full summary of the forum and presentations
can be found online at http://www.goviink.org!
watersheds/8/committees/15Tech Frm/defau It.aspx).
First -tier priorities:
Ballard Locks and Ship Canal operations —
What are feasible solutions to improve conditions
related to high temperature, low dissolved
oxygen, and concomitant decreased resistance
of salmonids to disease/parasites?
Rearing and refuge — What are the effects of a
lack of woody debris and floodplain connectivity
(levees, revetments) and other features of
adequate instream rearing habitat?
Lake survival — What are the effects of artificial
light and predation in Lake Washington, Lake
Sammamish, and the Ship Canal (predation in
Ship Canal may be a key limiting factor)?
High water temperature — What are the effects
of high water temperature in the Ship Canal and
Sammamish River?
Other important priorities:
Water quality — What are the effects of
stormwater on Chinook salmon, including toxic
loading of chemicals and contaminants? Are
current stormwater regulations and treatment
standards adequate? How can the pace of
retrofits be increased?
Streamflows — What are the effects of low
summer flows and "flashy" winter flows?
Invasive aquatic vegetation — What are the
effects of invasive aquatic vegetation on salmon
migration and survival?
Other limiting factors with potentially large
impacts:
• Piers and docks — What are the effects of
overwater structures on salmon migration and
survival?
Genetic introgression or other issues related to
hatchery operations — What are the effects of
hatcheries on the genetic fitness of natural origin
salmon?
In addition, the WRIA 8 TC identified the following
critical monitoring needs to track indicators
associated with key recovery goals. Juvenile
outmigrant trapping and adult spawner surveys
are currently funded in part by competitive grants;
other critical monitoring needs are unfunded.
• Juvenile outmigrant trapping
• Adult spawner surveys
• Wood volume surveys on all Tier 1 and
Tier 2 streams
• Lakeshore surveys: length of natural bank profile,
bulkheads, overwater structures
• Remote sensing: high -resolution land cover
mapping of forest cover and impervious surfaces
• Assessment of accessibility and habitat quality
of pocket estuaries and coastal streams entering
Puget Sound
Monitoring needs are outlined in more detail in the
Monitoring and Assessment Plan, Appendix A.
3. CURRENT STATUS

N CHINOOK SALMON STATUS
„ The general approach to determine the conservation status
a of Chinook salmon in the Puget Sound region is based on the
a viable salmonid population (VSP) concept. A VSP is defined as an
independent population with a negligible less than 5 percent) risk of
� P P P( p )
} extinction in their natural habitat over a 100-year period (McElhany
o et al. 2000). The attributes used to evaluate the status of Chinook
salmon are abundance, population productivity, spatial distribution,
c
and diversity.
m
ABUNDANCE
Adult abundance is the number of adult Chinook salmon returning
to WRIA 8 streams to spawn. In WRIA 8, abundance is monitored
by surveying each Tier 1 and Tier 2 stream for salmon redds during
the spawning season. Carcasses are surveyed for the presence or
absence of an adipose fin: the absence of an adipose fin indicates
hatchery origin. Abundance goals for Chinook salmon in WRIA 8
were set by the state and tribal Co -Managers and adopted in the
WRIA 8 Plan in 2005. The 10-year WRIA 8 abundance goal for the
Cedar River population was 1,680 natural -origin spawners (NOS).
Average return for the Cedar River population (2006-2015) was 1,012
NOS (Figure 4). The 10-year abundance goal for the Sammamish
River population (measured on Bear/Cottage Lake Creek) was 350
NOS. Average spawner abundance for Bear/Cottage Lake Creek
(2006-2015) was 47 NOS (Figure 5). A second 10-year WRIA 8 goal
for the Sammamish River population (measured on Bear/Cottage
Lake and Issaquah creeks) was to maintain the base period average
escapement of 1,083 adults (combined hatchery -origin and natural -
origin spawners). Average return for the Sammamish River population
(2006-2015) was 1,269 adults (including HOS).

Figure 5. Bear Creek/Cottoge Lake Creek Chinook Salmon Abundance: Natural -Origin Spawners (NOS),
2004-2015
While WRIA 8 has no
quantitative goals forjuvenile
Chinook salmon abundance,
the watershed funds juvenile
abundance monitoring through
outmigrant trapping on the
Cedar River and Bear Creek.
Juvenile Chinook salmon
abundance has significantly
increased in recent years (Figure
6 and Figure 7).
PRODUCTIVITY
Productivity indicates whether
a population is growing or
shrinking over time. Given the
very low overall abundance
of Chinook salmon in WRIA 8,
high productivity is necessary
to restore the population to
historical levels. Overall Chinook
salmon productivity is influenced
by factors throughout the full
salmon lifecycle, including
elements outside the control
of WRIA 8 partners, such
as marine Survival. Juvenile
productivity, however, mostly
reflects habitat factors within the
control of WRIA 8 partners, such
as watershed hydrology and
juvenile rearing habitat quantity
and quality. For this reason,
WRIA 8 focuses on juvenile
productivity as a key indicator
of progress.
Adult productivity is assessed
and reported by the NOAA
Northwest Fisheries Science
Center at five-year intervals.
The most recent review
was published in 2015, and
reported on Chinook salmon
status through 2011 (NWFSC,
2015). Fifteen -year trends in

productivity are reported by a method where a
number above zero indicates positive productivity,
while a number below zero indicates a population
that is not replacing itself (NWFSC, 2015). Data
through 2011 indicated that the Cedar River
population has shown a positive productivity trend.
The Sammamish population displays a negative
trend through 2011.
Adult spawner surveys and juvenile outmigrant
trapping allows the watershed to estimate juvenile
productivity. WRIA 8 uses egg -to -migrant survival
as its indicator ofjuvenile productivity. The 10-
year juvenile survival rate goals in the 2005 Plan
for WRIA 8 Chinook salmon from egg deposition
to the trapping location were 13.8 percent and
4.4 percent for the Cedar and Bear populations,
respectively.2 The average survival rates for the
last 10 years (brood years 2004-2013) are 22.2
percent for the Cedar population and 7.64 percent
for the Bear population.
SPATIAL DISTRIBUTION
The distribution of a population throughout a
landscape provides an insurance policy against
isolated catastrophes, such as floods or landslides
that affect only a small geographic area. WRIA
8 salmon populations possess a greater chance
of long-term survival if they are able to spawn
and rear successfully throughout the landscape.
During times of high abundance, salmon are more
likely to spread out and use less ideal habitats,
and colonize nearby streams and basins. During
periods of low abundance, spawning salmon
spatial distribution is more likely to contract to
prime spawning areas.
In WRIA 8, the 10-year goal in the 2005 Plan was
to maintain and, where opportunities existed,
increase the spawning and rearing distribution of
Chinook salmon throughout the watershed. Annual
spawning ground surveys indicate increasing use
of the Cedar River above the Landsburg Diversion
Dam since creation of a fish passage facility there
in 2003. Similarly, recent construction of a fish
passage project at the hatchery intake diversion on
Issaquah Creek will likely increase Chinook use of
the upper creek.
2Juvenile survival is an indicator of freshwater production above the trapping location. In WRIA 8, those locations are
in the lower Cedar River and lower Bear Creek. Survival from the trapping location to the eventual exit of the WRIA 8
system at the Ballard Locks can be estimated through the use of passive inductance transponder (PIT) tag readers.
Measured at the Locks,juvenile survival integrates overall survival through Lake Washington and (for the Bear Creek
migrants) through the Sammamish River. Currently, the complex nature of the passage options forjuvenile Chinook
salmon through the Locks makes estimating overall survival problematic. In 2016, an additional PIT tag array in one of
the lock -filling culverts should improve our ability to estimate the survival ofjuvenile Chinook salmon to the Locks.

Table 4. WRIA 8 Chinook Salmon Redd Survey Results, 1999-2015
DIVERSITY
WRIA 8 partners monitor diversity through
assessments of the age of returning adults, the
proportion of juvenile salmon migrating as fry
(early) or parr (later), and the proportion of hatchery
fish on the spawning grounds. WRIA 8 goals are
to increase the proportion of parr migrants on
the Cedar River, and decrease the proportion of
hatchery -origin Chinook salmon spawning with
natural -origin fish.
The number of parr migrants has not increased
consistently (Figure 8). Fry migrants have driven
the overall increase in juvenile migrants in recent
years (Figure 6 and Figure 7). This and other data
indicate that freshwater rearing and refuge habitat
continues to limit the production of parr migrants.
This information confirms that our primary goal of
increasing freshwater rearing and refuge habitat
is still a priority. We expect that over time, as more
rearing and refuge habitat is restored, the number
of parr migrants will increase.
WRIA 8 goals in the 2005 Plan were to see a
decrease in the proportion of hatchery -origin
spawners to below 20 percent for the Cedar
population and to increase the proportion of
natural -origin spawners in the Sammamish
population. For the Cedar population, the
proportion of hatchery -origin spawners was
below 20 percent between 2007 and 2013, but
has recently increased (Figure 9). We speculate
that recent high temperatures during the late
summer/early fall migration period have induced
more hatchery -origin Chinook salmon to migrate
to the Cedar River, rather than return through the
much warmer Sammamish River to the Issaquah
hatchery. The proportion of hatchery -origin
spawners is consistently high (over 70 percent) for
the Sammamish population (Figure 9).

HABITAT STATUS
The condition of the watershed varies between
lower elevations that have been intensively
developed and higher elevations that are more
pristine. Current stream habitat conditions in most
areas inside the UGA boundary in WRIA 8 are
degraded, largely because of land conversion and
associated effects of human activities. Data on
habitat status since 2005 includes a forest cover
analysis (Vanderhoof et al., 2011) and a wadeable
streams status and trends monitoring project
(King County, 2015), as well as ongoing annual
monitoring of water quality and macroinvertebrates
(indirect indicators of habitat quality) conducted by
King County and other jurisdictions. The wadeable
streams project collected data on pools, wood
in streams, sediment, riparian canopy cover, and
many other metrics. Other studies in the watershed
that provide valuable information on habitat
status include a U.S. Geological Survey (USGS)
longitudinal profile of the Cedar River (Konrad
et al., in press), Bear Creek watershed planning
research (King County, 2017), and high -resolution
land cover mapping by NOAA using 2015 aerial
photography (NOAA, 2017).
Important locations lacking in recent data include
the lake shorelines, where information on
bulkheads, docks, and lakeshore conditions is
necessary to track improvements or degradation.
Other habitat status and trends monitoring needs
are outlined in the Monitoring and Assessment
Plan (Appendix A).
RIVERS AND STREAMS
Cedar River and Tributaries (Tier 1)
The Cedar River contains the highest priority
spawning and rearing areas in WRIA 8 and (with its
tributaries) is the sole spawning and rearing stream
for the Cedar River Chinook salmon population.
The river supports the largest number of natural -
origin Chinook salmon in the basin, and contains
the primary spawning areas for Lake Washington
sockeye and steelhead. A fish passage facility
installed at the Landsburg water supply diversion
dam in 2003 substantially increased the extent of
Chinook salmon spawning and rearing habitat by
over 17 miles in the watershed, and reconnected
the full historical extent of migratory habitat. The
river upstream of the Landsburg Diversion Dam
is protected by a 50-year HCP administered
by Seattle Public Utilities, and is used annually
by a substantial proportion of Chinook salmon
returning to the watershed. The river upstream from
Landsburg Diversion Dam to the natural barrier at
Cedar Falls was reclassified to Tier 1 habitat status
in 2017. Aside from some service roads, this area is
unconfined by levees or other artificial structures,
and the riparian zone is dominated by second -
growth conifer forest.
Of the 1,419 acres in the moderate CMZ below
Landsburg Diversion Dam as of 2015, approximately
380 acres (26 percent) are behind levees,
revetments, or other hard structures. (WRIA 8 uses
the moderate CMZ as a proxy for its floodplain
metric.) Between 2005 and 2015, approximately 65
acres of floodplain were reconnected through levee
setbacks and floodplain restoration.
Using a recent remote -sensing product (NOAA,
2015), the TC estimates the instream area of
woody debris in the Cedar River between RM
4 and Landsburg as 5.2 m2/100 m. If the typical
jam is assumed to be 2 meters tall, the estimated
wood volume would be 10.4 m3/100 m (WRIA 8 TC,
unpublished GIS data; King County, 2015). This
value is substantially below regional benchmarks
for rivers of this size (Fox and Bolton, 2007) and the
TC considers this value to reflect poor condition
(well below the 25th percentile for rivers 30 meters
bankfull width or greater).
Using a high -resolution (1 meter) land cover
product (NOAA, 2017), the WRIA 8 TC estimated
the 2015 forest cover within 200 feet of the
channel centerline as 70 percent outside the UGA
boundary and 39 percent inside the UGA (WRIA
8 TC, unpublished data). Impervious cover extent
was estimated at 4 percent outside the UGA and 18
percent inside.
Sammamish River (Tier 1)
The Sammamish River is a low -gradient
waterbody connecting Lake Sammamish and Lake
Washington, and is the migratory pathway to and
from Lake Washington for salmon originating in
the Issaquah and Bear Creek/Cottage Lake Creek
systems, as well as for Chinook and coho salmon
produced at the Issaquah salmon hatchery. The
Sammamish River valley was heavily modified in
the 20th century, and the river is channelized and
armored along its entire length. The Sammamish
River is classified as a flood conveyance facility
by the USACE; opportunities for levee setback
projects are minimal. King County designated a
portion of the Sammamish Valley as an agricultural
production district (APD), to preserve agricultural
production. While development pressure is
reduced in the APD, efforts to restore habitat in
this area may be limited and will need to consider
these agricultural designations and work closely
with agricultural preservation interests.
A recent remote -sensing product (NOAA, 2015)
detected zero incidence of large wood in the
Sammamish River (WRIA 8 TC, unpublished GIS
data). However, constructed logjams are known
to be present in the Sammamish River in and
near Redmond. Notwithstanding the few known
logjams, the TC considers the Sammamish River to
reflect poor condition for wood volume.
Using a high -resolution (1 meter) land cover
product (NOAA, 2017), the WRIA 8 TC estimated
the 2015 forest cover within 200 feet of the
Sammamish River channel centerline as 16 percent
outside the UGA boundary and 32 percent
inside the UGA (WRIA 8 TC, unpublished data).
Impervious cover extent within the 200-foot area
was estimated at 6 percent outside the UGA and
15 percent inside.
Bear Creek/Cottage Lake Creek (Tier 1)
The Bear Creek/Cottage Lake Creek system is
the primary spawning tributary for the naturally
produced portion of the Sammamish River Chinook
salmon population. The lower reaches of the
Bear Creek/Cottage Lake system are heavily
urbanized in Redmond near the confluence with
the Sammamish River. Farther upstream, rural/
suburban land uses predominate.
Using a high -resolution (1 meter) land cover product
(NOAA, 2017), the WRIA 8 TC estimated the 2015
forest cover within 200 feet of the Bear Creek
channel centerline as 69 percent outside the UGA
boundary and 35 percent inside the UGA (WRIA 8
TC, unpublished data). Cottage Lake Creek forest
cover (all outside the UGA) was estimated at 39
percent. Impervious cover within the 200-foot area
was estimated at 4 percent outside the UGA and 19
percent inside for Bear Creek, and 10 percent for
Cottage Lake Creek.
Wood volume for seven sites sampled annually
in the Bear Creek/Cottage Lake Creek basin
between 2010 and 2013 averaged 22.8 m3/100 m
(WRIA 8 TC, unpublished data; King County, 2015).
This value is slightly below the 25th percentile of
the distribution of wood volume for unmanaged
western Washington streams less than 30 meters
bankfull width (Fox and Bolton, 2007). The TC
considers this value to reflect poor condition for
wood, though more sites should be sampled to
characterize the overall stream system with
greater confidence.
Issaquah Creek (Tier 1)
Issaquah Creek is a potentially significant spawning
area for Chinook salmon in WRIA 8. A fish passage
facility installed at the Issaquah salmon hatchery
water supply diversion dam in 2013 opened up 11
miles of Chinook salmon spawning and rearing
habitat in the watershed, and reconnected the
hypothesized extent of historical migratory habitat.
The lower reaches of Issaquah Creek are heavily
urbanized in Issaquah near the confluence with
Lake Sammamish, though the bottom -most reaches
flow through Lake Sammamish State Park. Farther
upstream, rural/suburban, recreation, and forestry
land uses predominate.
Using a high -resolution (1 meter) land cover product
(NOAA, 2017), the WRIA 8 TC estimated the 2015
forest cover within 200 feet of the Issaquah Creek
channel centerline as 82 percent outside the UGA
boundary and 60 percent inside the UGA (WRIA
8 TC, unpublished data). Impervious cover extent
within the 200-foot area was estimated at 3 percent
outside the UGA and 15 percent inside.
Wood volume for 13 sites sampled annually in the
Issaquah Creek basin (including Carey, Holder, and
East Fork Issaquah creeks) between 2010 and 2013
averaged 30.7 m3/100 m (WRIA 8 TC, unpublished
data; King County, 2015). This value is above the
25th percentile of the distribution of wood volume
for unmanaged western Washington streams less
than 30 meters bankfull width (Fox and Bolton,
2007). The TC considers this value to reflect overall
fair condition for wood in the Issaquah Creek
system, though the wood volume in much of the
lower extent is low or very low.
Little Bear Creek (Tier 2)
Little Bear Creek is a tributary to the Sammamish
River, joining the Sammamish River at Woodinville.
Most of the upper reaches are rural/suburban.
Spawning by Chinook salmon in Little Bear Creek
is intermittent, though sockeye salmon regularly
spawn in the lower reaches.
Using a high -resolution (1 meter) land cover product
(NOAA, 2017), the WRIA 8 TC estimated the 2015
forest cover within 200 feet of the Little Bear Creek
channel centerline as 83 percent outside the UGA
boundary and 44 percent inside the UGA (WRIA
8 TC, unpublished data). Impervious cover extent
within the 200-foot area was estimated at 5 percent
outside the UGA and 44 percent inside.
Wood volume was sampled annually at two sites
in Little Bear Creek between 2010 and 2013, and
averaged 5.3 m3/100 m (WRIA 8 TC, unpublished
data; King County, 2015). This value is significantly
below the 25th percentile of the distribution of
wood volume for unmanaged western Washington
streams less than 30 meters bankfull width (Fox
and Bolton, 2007). The TC considers this value to
reflect very poor condition for wood in Little Bear
Creek, though more sites should be sampled to
characterize the overall stream system with
greater confidence.
North Creek (Tier 2)
North Creek is a tributary to the Sammamish River,
joining the Sammamish at Bothell. Spawning by
Chinook salmon in North Creek is intermittent. The
entire North Creek basin is inside the UGA.
Using a high -resolution (1 meter) land cover product
(NOAA, 2017), the WRIA 8 TC estimated the 2015
forest cover within 200 feet of the North Creek
channel centerline as 70 percent (WRIA 8 TC,
unpublished data; King County 2015). Impervious
cover extent within the 200-foot area was
estimated at 14 percent.
Wood volume was sampled annually at four sites in
the North Creek basin between 2010 and 2013, and
averaged 22.7 m3/100 m (WRIA 8 TC, unpublished
data; King County, 2015). This value is below the
25th percentile of the distribution of wood volume
for unmanaged western Washington streams less
than 30 meters bankfull width (Fox and Bolton,
2007). The TC considers this value to reflect overall
poor condition for wood in North Creek, though
more sites should be sampled to characterize the
overall stream system with greater confidence.
Kelsey Creek (Tier 2)
Kelsey Creek is a tributary to Lake Washington,
draining into Lake Washington through Bellevue.
Spawning by Chinook salmon in Kelsey Creek is
intermittent. The entire Kelsey Creek basin is inside
the UGA.
Using a high -resolution (1 meter) land cover product
(NOAA, 2017), the WRIA 8 TC estimated the 2015
forest cover within 200 feet of the Kelsey Creek
channel centerline at 56 percent (WRIA 8 TC,
unpublished data). Impervious cover extent within
the 200-foot area was estimated at 16 percent.
Wood volume was sampled annually at four sites
in the Kelsey Creek basin between 2010 and
2013, and averaged 18.3 m3/100 m (WRIA 8 TC,

unpublished data; King County, 2015). This value
is below the 25th percentile of the distribution of

and Bolton, 2007). The TC considers this value
to reflect overall very poor condition for wood
in Kelsey Creek, though more sites should be
sampled to characterize the overall stream system
with greater confidence.
Other Chinook Salmon Creeks
in WRIA 8 (Tier 3)
Regular Chinook salmon spawner surveys occur
in May and Coal creeks, both tributaries to Lake
Washington a few miles north of the Cedar River.
Spawning by Chinook salmon in these creeks is
intermittent. Other Tier 3 streams in WRIA 8 are not
regularly surveyed for Chinook spawning.
Forest cover within 200 feet of the Coal Creek
channel centerline in 2015 was estimated at 100
percent outside the UGA and 84 percent inside
(WRIA 8 TC, unpublished data; King County, 2015).
Impervious cover extent within the 200-foot buffer
was estimated at 0 percent outside the UGA, and
7 percent inside. For May Creek, the 2015 forest
cover within 200 feet of the channel centerline
was estimated at 48 percent outside the UGA and
81 percent inside (WRIA 8 TC, unpublished data;
King County, 2015). Impervious cover extent within
the 200-foot area was estimated at 5 percent
outside the UGA and 8 percent inside.
Wood volume was sampled at one site in the
May Creek basin and two in the Coal Creek
basin annually between 2010 and 2013. Wood
volume averaged 64.0 m3/100 m at May Creek
and 40.6 m3/100 m in Coal Creek (WRIA 8 TC,
unpublished data; King County, 2015). The May
Creek site exceeded the median and the Coal
Creek sites averaged slightly below the median of
the distribution of wood volume for unmanaged
western Washington streams less than 30 meters
bankfull width (Fox and Bolton, 2007). The TC
considers these values to reflect overall fair
condition for wood, though more sites should be
sampled to characterize the overall stream systems
with greater confidence.
LAKE WASHINGTON AND LAKE
SAMMAMISH SHORELINE (TIER 1)
Lake shoreline habitats in both Lake Washington
and Lake Sammamish are important for
outmigrating and lake -rearing juvenile Chinook
salmon. Juvenile salmon use shallow -water
lake shoreline areas to escape predators and
to feed as they enter the lakes as fry. Shoreline
conditions were initially degraded by the lowering
of Lake Washington during construction of the
Ballard Locks, and impacts from urbanization and
shoreline development have further degraded
shoreline conditions. The majority of lake
shorelines are in private residential ownership,
with landscaped yards and bulkheads or other
shoreline armoring. Earlier studies indicated that
approximately 75 percent of Lake Washington's
shoreline has a bulkhead or other form of shoreline
armoring (Taft at al., 2003). These conditions have
altered or eliminated much of the shallow -water
habitat around the lake, reduced emergent and
riparian vegetation, reduced the amount of large
wood, and changed sediment dynamics.
Using a high -resolution (1 meter) land cover
product (NOAA 2017), the WRIA 8 TC estimated
the 2015 forest cover within 200 feet of the
shoreline as 38% (Lake Washington) and 36%
(Lake Sammamish) (WRIA 8 TC, unpublished data).
Impervious cover extent within the 200-foot area
was estimated at 28% (Lake Washington) and 36%
(Lake Sammamish).
Recent information on bulkheads, docks, and
lakeshore conditions is lacking, but necessary to
track improvements or degradation.
MARINE NEARSHORE
The marine nearshore portion of WRIA 8
encompasses approximately 24 miles of shoreline,
from West Point north to Elliot Point in Snohomish
County. The nearshore is of primary importance
forjuvenile salmon for rearing and migration as
they make their way through Puget Sound to the
ocean. In particular, areas where small coastal
streams enter Puget Sound have been identified
as important forjuvenile salmon rearing and refuge
during migration (Beamer et al., 2013).
With a few notable exceptions, recent status
information is not available for the WRIA 8 marine
nearshore. The BNSF railroad along most of the
shoreline disconnects upland habitats from the
nearshore and interrupts natural beach creation
and erosion processes; this condition is not likely
to change without engagement with and support
from BNSF. For information on the status of marine
shorelines prior to 2005, see the 2005 Plan
and Kerwin (2001).
PRESSURES ASSESSMENT
During development of the 2017 Plan, the WRIA 8
TC assessed the primary human -induced impacts
on Chinook salmon and their habitat through a
systematic "pressures assessment" This exercise
evaluated the various impacts —or pressures —
faced by Chinook salmon during each of the life
stages represented in the conceptual model. Since
each life stage relies on specific habitat types at
particular locations and at certain times of year,
evaluating pressures on certain life stages takes
into account location in the watershed, use of
habitat, and the timing of that use. The pressures
assessment used a regionally standardized list of
pressures and rated each according to its scope,
severity, and irreversibility at each life stage.
The WRIA 8 TC used their knowledge of local
conditions, local monitoring and scientific studies,
and other studies from the scientific literature
as the basis for their assessment. The pressures
assessment process and results are further
described in Appendix C.
Priority pressures
The most significant pressures in WRIA 8 are
hypothesized to be land conversion, existing
levees and revetments, shoreline armoring (marine
nearshore, lakes and Ship Canal), altered peak
flows, increased water temperatures, predation,
and pressures associated with migration through
the Ballard Locks. Many of these pressures are
interconnected and one may exacerbate another
(for example, increased water temperatures are
likely to increase the efficiency of warm water
predators such as bass in the Ship Canal). These
seven most significant pressures are described
below, based on the definitions of the Puget
Sound Partnership and modified slightly to
be most relevant to WRIA 8. The assessment
considered climate change not as a separate
pressure but through its exacerbating effects on
the other pressures in the Lake Washington/Cedar/
Sammamish Watershed.
The WRIA 8 TC has documented its rating of the
full list of pressures that threaten the recovery
of Chinook salmon in WRIA 8. These pressures
are described in Appendix C. The impacts of
these pressures in WRIA 8 are assumed based
on studies and data from other watersheds, but
these pressures are well known in general (WDFW,
2009). The specific empirical data associated with
these pressures is not included in this document.
Land conversion. Land conversion is the
conversion of land from natural cover to one
dominated by residential, commercial, and/
or industrial development or one dominated by
agriculture. Land conversion reduces the extent
and quality of habitat. Related pressures such as
pollution, shoreline hardening, and other cascading
effects of land conversion are assessed separately.
Note that conversion is often a step -wise process.
Some areas of WRIA 8 have converted from
natural cover to agriculture, while others have then
converted from agriculture to urban or suburban
development. Compared to other Puget Sound
watersheds, development pressure and the rate
of urbanization have been and continue to be
very high in WRIA 8. This pressure includes the
legacy effects of past conversion and ongoing
degradation from continued development.
Levees and revetments.3 Levees and revetments
are structures, often originally intended for flood
control, that block or restrict movement of water,
sediment, or debris flow in the river or stream
channel and consequently change sediment and
debris delivery. These structures may also be
barriers to movement of species. The structures
built along the Cedar and Sammamish rivers
in WRIA 8 block habitat connectivity within the
floodplain, prevent inundation of off -channel
habitat, and keep fish from accessing what refuge
habitat might remain behind the levees. Relative
to the Sammamish River system, the Cedar
River system has more opportunity for setting
back levees and re-creating habitat with some
additional constraints to consider, such as flood
protection, trails, and regional fiber-optic lines
located underneath the Cedar River Trail along
much of its length.
Shoreline armoring. Shoreline armoring
changes shoreline features in a manner that
reduces habitat extent and/or disrupts shoreline
processes. The primary source of this impact
is the construction of shoreline infrastructure,
often as part of land conversion activities, that
produces a hard linear surface along the beach or
streambank intended to reduce erosion. In WRIA
8, natural shallow shoreline and creek mouths
in Lake Washington and Lake Sammamish have
been changed by shoreline hardening. In addition,
the BNSF track running along most of the WRIA
8 marine shoreline is armored, disconnecting
backshore areas and pocket estuaries from Puget
Sound, while also disrupting the natural supply of
beach sediment from eroding bluffs. In most cases,
shoreline armoring also eliminates vegetated
cover and thus exacerbates other pressures on
Chinook salmon (e.g., water temperature and
predation), and interferes with food
web processes.
Altered flows. Altered flows into and within surface
waters are caused by changes in land cover,
the associated surface hardening (impervious
surfaces), and changes in precipitation volume and
timing due to climate change, as well as associated
impacts such as changes in sediment and debris
delivery. Heavy rains and high flows can cause
scouring and high water velocities that can push
salmon out of the habitat they need for rearing
and spawning. Altered low flows, often caused
when impervious surfaces prevent infiltration and
groundwater recharge, can be exacerbated by
climate change and water withdrawals. Peak flows
can be challenging to salmon in fall and winter,
while low flows are most often problematic in
summer and early fall.
Increased water temperatures. A specific water
quality issue, high temperatures are linked to and
can exacerbate many other pressures in WRIA
8. Increased water temperatures in WRIA 8 are
caused by land conversion, altered flows, a lack
of riparian cover and groundwater connections,
infrastructure (e.g., Ballard Locks) and inadequate
estuarine mixing, and climate change. Water
temperatures are of greatest concern in the Ship
Canal and Sammamish River, but can also be
problematic in all streams.
Increased predation by native and non-native
species. Increased predation results from the
increase or spread of native and non-native fish
and other wildlife. Predation on juvenile Chinook
salmon is almost certainly a key pressure that
affects their recovery in WRIA 8. Predatory fish
documented in the Ship Canal include smallmouth
bass, largemouth bass, rock bass, yellow perch,
and northern pikeminnow (Tabor et al., 2004,
2007, 2010; WDFW/King County unpublished
data). More recent studies have investigated the
3 Levees are raised embankments built parallel to rivers and are intended to contain or direct flood flows, sometimes
allowing water surface elevations in the river or stream to exceed the elevation of the surrounding floodplain.
Revetments are not designed to contain floodwaters but rather serve the purpose of preventing bank erosion or
lateral channel migration (King County, 2006).
impact of predation from resident cutthroat and
rainbow trout (O. mykiss) from 2006 to 2010 in the
Cedar River below the Landsburg Diversion Dam
(Taboret al. 2014). Issues such as artificial night-
time lighting, shoreline hardening and overwater
structures, and increased water temperatures
exacerbate the effects of predation on Chinook
salmon in WRIA 8.
Impacts to fish passage and survival at the
Chittenden (Ballard) Locks. The Ballard Locks
is one of the most significant single structures
affecting Chinook salmon recovery in WRIA 8. The
creation of the Ship Canal and the Ballard Locks in
1916 forever changed the hydrology and function
of the watershed by shifting outflow of water from
its historic exit in south Lake Washington through
the Black River to its present-day configuration
through the Montlake Cut, Salmon Bay, and into
Shilshole Bay (Chrzastowski,1981). All WRIA 8
anadromous fish populations must move through
the Ballard Locks as they migrate out of and
into the watershed. Chinook salmon experience
physical trauma, stress and mortality at the Ballard
Locks due to elevated water temperatures,
decreased dissolved oxygen, and the physical
barrier presented by the structure (NMFS, 2008).
CLIMATE VARIABILITY,
CLIMATE CHANGE, AND
IMPACTS TO SALMON
In the years since the adoption of the 2005 Plan,
our understanding of the effects of a changing
climate on Chinook salmon and salmon habitat,
and restoration techniques to mitigate those
effects, has grown substantially. Research from the
Northwest and elsewhere suggests we can and
must plan for and adapt to changing watershed
conditions and incorporate the concept of
resilience into salmon recovery actions.
Intact ecosystems are inherently more resilient
systems. Stream corridors with intact riparian zones
and floodplains help dissipate destructive flood
waters and shade streams from direct sunlight.
Stormwater that is allowed to infiltrate into the
ground is slowed, cleansed, and cooled before it
reaches our streams and lakes. Wood in stream
channels can create pools of deeper, cooler water
and cover for fish to hide from predators, and can
help to lessen the force of floods. Salmon habitat
restoration and protection strategies focused on
reconnecting floodplains and restoring stream
corridors, lake shores, and marine shorelines make
our ecosystems and communities more resilient to
a changing climate. The present and anticipated
effects of climate change emphasize the need to
increase the pace of salmon habitat protection
and restoration.
NATURAL CLIMATE VARIABILITY
AND CLIMATE CHANGE
The Northwest climate naturally varies seasonally,
as well as annually, between cool and hot, wet and
dry. Year to year variability is generally associated
with the El Nino Southern Oscillation (ENSO) which
affects ocean currents and temperature as well as
global precipitation and air temperature. Longer
term decadal patterns are often described by the
Pacific Decadal Oscillation, a pattern defined by
variations in sea surface temperatures in the North
Pacific Ocean.

Notwithstanding the natural variability around
climate patterns in the Northwest, the Puget Sound
region is already experiencing some of the effects
of a changing climate. Records show that all but
six of the years from 1980-2014 were above the
20th century average temperature (Mauger et
al., 2015). The waters of the North Pacific Ocean
and Puget Sound are becoming more acidic as
a consequence of increasing carbon dioxide in
the atmosphere. Recent years have seen record
average summer air temperatures; by mid-century,
annual average air temperatures are projected to
rise between 4.2 and 5.9 degrees Fahrenheit (F),
exacerbating surface water warming. Computer
models predict a decline in summer precipitation
as well as increases during fall, winter and spring.
The region's snowpack is expected to decrease as
winters get warmer and wetter. Winter rainstorms
are projected to become more intense, which can
lead to increased flooding and erosion.

PROJECTIONS AND EFFECTS ON
WRIA 8 CHINOOK SALMON
Salmon in WRIA 8 are projected to face threats
related to changes in the timing and intensity
of precipitation, increasing air and water
temperatures, a reduction in snowpack at low
and middle elevations, sea level rise, and ocean
acidification. The effects can be grouped into the
categories of temperature and precipitation, altered
hydrologic patterns, stormwater, sea level rise, and
ocean acidification.
Temperature and precipitation
Average annual air temperature for the Puget
Sound region has increased by about 1.3 degrees
F from 1895 to 2014, while average nighttime air
temperatures have increased by 1.8 degrees F.
The frost -free season has lengthened by 30 days
from 1920 to 2014 (Mauger et al., 2015). Water
temperatures will be especially affected by this
warming during increasing periods of summer
low flows, when they are highly influenced by air
temperature. Warmer temperatures will accelerate
snow melt during spring and early summer and
decrease snow accumulation in winter. While a
rising temperature trend is evident in the long-
term record, there is no current evidence of
a corresponding trend in annual precipitation
(Mauger et al., 2015); however, the timing and
intensity of precipitation events will likely change.
Most scenarios of future climate change project a
decline in summer precipitation and increases in
winter precipitation extremes (e.g., "atmospheric
river" events). While average annual precipitation
may be relatively constant, the timing and intensity
of events will change.
Increasing temperatures will affect all life stages
of Chinook salmon in WRIA 8, though they are
likely to have the most impact on migrating adults
and juveniles, especially in the Ship Canal and
Sammamish River. Water temperatures above
about 77 degrees F can kill Chinook (Richter and
Kolmes, 2005), though Chinook salmon appear to
be able to withstand higher temperatures for short
periods. At about 70 degrees F, adult migration
can be blocked. When salmon hold and migrate
at temperatures above around 63 degrees F,
there is an increase in sublethal effects such as
egg abnormalities, or increased susceptibility to
parasites or disease (Richter and Kolmes, 2005).
Juvenile outmigration behavior also changes
when temperatures warm in spring, with juveniles
avoiding the warmer surface waters in the Ship
Canal as water temperature approaches 68
degrees F (DeVries and Shelly, 2017). Additionally,
warm -water predators such as bass become more
active as temperatures rise, and are known to
consume Chinook salmon in the Ship Canal during
spring outmigration (WDFW and King County,
unpublished data).
Adult Chinook returning in the late summer and fall
tend to congregate in areas of cooler water until
environmental cues trigger upstream migration.
Temperature mitigation strategies will likely involve
efforts to create cooler -water refuges in the Ship
Canal and Sammamish River during adult migration
periods. Mitigation strategies for juveniles are
also yet to be developed. Current concepts being
discussed by the TC involve potential management
of warm -water predators at key areas (e.g., in the
Ship Canal).
The timing of the spring plankton bloom may
also be affected by warming lake temperatures.
Plankton support the aquatic food web and a
shift in timing may alter predator -prey dynamics
and food sources for salmon species (Mauger et
al., 2015). In the marine environment, changing
temperature patterns are likely to affect coastal
upwelling and ocean currents, with changes to
the composition, abundance, and distribution of
marine plankton communities, the basis of the
ocean food web. Since salmon spend the majority
of their lives in the ocean, these changes will affect
overall salmon migration and survival patterns in
ways that are as -yet insufficiently studied.
Changing precipitation regimes in WRIA 8 are
likely to exacerbate temperature problems during
summer and late fall if the timing of fall rains
is delayed.
Altered hydrologic patterns
The changing intensity and timing of precipitation
events will affect stream flow throughout WRIA 8.
More winter precipitation will fall as rain rather than
snow, resulting in less winter snow accumulation,
higher winter stream flows, increased scour,
earlier snowmelt, and lower summer stream flows.
Atmospheric river' storm events may result in
more damaging floods that destroy salmon habitat,
scour redds, and displace juveniles downstream.
Mitigating the challenges associated with
altered hydrologic patterns involves floodplain
reconnection and levee setbacks, and other
actions that protect and restore connectivity of
the stream system, restoring summer stream flow
regimes (e.g., through purchase of water rights
or other water conservation measures), reducing
erosion and sediment delivery problems (e.g.,
through restoration of stream channel complexity
and other stormwater control measures), restoring
riparian functions (e.g., shading, root reinforcement
of banks, natural large wood recruitment, trapping
sediment etc.), and instream rehabilitation
measures (e.g., channel reconstruction, wood
installation, gravel additions) (Beechie et al., 2012).
Stormwater
Polluted stormwater runoff is known to be a serious
issue for salmon in the Puget Sound region. It is
currently considered the top source of pollutants
to the Sound. With predicted increases in heavy
rainfall events in fall and winter, stormwater runoff
will increase pollutant discharge into rivers and
streams and, ultimately, Puget Sound. Pesticides,
heavy metals, bacteria, motor oils and other
pollutants already contribute significantly to
stormwater pollution in our region. Stormwater
can affect the watershed by washing toxics into
streams, and adding nutrients that increase algal
blooms and decrease oxygen levels. A key impact
of increased stormwater runoff on Chinook salmon
is the associated increase in the "flashiness" of the
hydrograph, meaning higher, more sudden peak
flows during storms. These flows can scour stream
beds and banks, flushing out habitat -forming debris
and organic matter important to macroinvertebrate
communities and small fish. Concentrations of
toxic pollutants in stormwater have been shown to
cause mutations in salmon embryos and rearing
juvenile salmon, though effects on Chinook
salmon in WRIA 8 have not been directly observed
(Meador et al., 2006). Current research studying
the effects of toxic pollutants in stormwater on
Chinook salmon survival should help improve the
understanding of how great an impact this aspect
of stormwater has on juvenile and adult
Chinook survival.

Actions to mitigate the effects of stormwater on
salmon include retrofits to areas and facilities
developed prior to regulatory requirements;
application of low impact development
techniques like green stormwater infrastructure;
streamside plantings; improved tracking, control
and elimination of pollutant sources; and other
efforts to restore a natural hydrograph, recharge
groundwater, lower stream temperatures, and
treat, filter or otherwise eliminate bacteria and
other pollutants. Many older developed areas
lack adequate stormwater controls. Treating and
retaining stormwater at its source before it runs off
into streams and rivers may reduce fish exposure
to chemicals and stressful hydrologic and water
quality conditions.
Sea level rise
The melting of mountain glaciers and ice sheets at
both poles, in addition to thermal expansion of the
oceans, will continue to result in rising sea levels.
Higher sea levels contribute to destructive storm
surges and coastal flooding. Low-lying coastal
areas will be inundated, and coastal wetlands will
become increasingly brackish; coastal communities
and shallow nearshore areas, which are rearing
areas for young salmon, will expand or contract
depending on existing shoreline armoring and
future efforts to accommodate or prevent intrusion.
In WRIA 8, shoreline armoring is nearly continuous
because of the BNSF rail corridor along the coast.
This will likely result in a decrease in already
limited marine nearshore rearing habitat. Rising
sea levels may also affect operation of the Ballard
Locks, which could negatively impact fish passage,
as well as water quality conditions in the
Ship Canal.
Ocean acidification
As oceans absorb excess carbon dioxide from the
atmosphere, ocean water will become more acidic.
Ocean acidification makes it more difficult for many
marine organisms to create shells and skeletons,
which could disrupt food resources for salmon and
other fish. Studies are limited, but modeling of the
Puget Sound food web suggests that alternative
sources of food that are not directly affected by
acidification may be available for salmon. More
research is needed on this issue.

KEY ACTIONS TO FOSTER CLIMATE RESILIENCE IN WRIA S
Changing climate conditions affect many aspects of salmon recovery and underscore the
importance of improving ecosystem resiliency. Below are several key actions to improve
ecosystem resiliency and address current and anticipated effects of a changing climate, which
are consistent with WRIA 8 salmon recovery strategies and recommended implementation
actions discussed in Sections 4 and 5.
• Work toward resilience by encouraging and restoring natural processes that may moderate
expected changes (e.g., floodplain reconnection and restoring natural shorelines).
• Identify how habitat boundaries, such as floodplains, are changing. Limit armoring
shorelines where feasible by protecting and restoring shoreline properties. Protect habitat
outside current habitat boundaries if evidence exists that habitat boundaries will change.
Protect or acquire land that will be inundated by increased flooding and sea level rise.
• Study potential engineered solutions in high -priority, heavily modified areas like the Ship
Canal and Sammamish River (e.g., hypolimnetic withdrawal in Lake Washington and/or Lake
Sammamish, or chillers to create localized thermal refugia).
• Identify, protect and enhance processes and habitats, such as stream headwaters areas,
that provide cool water. Protect and replant forests and riparian buffers, and locate
groundwater sources and seeps and protect natural processes that create critical habitats
like wetlands, tidal flats, marshes and estuaries; this will help ensure that water can be
stored, recharged, and delivered at a moderated pace and temperature. Monitor land cover
change and promote actions to minimize impacts to hydrology.
• Protect and restore tributary streams, which are often cooler than mainstem rivers and can
provide salmon with cold water refugia.
• Reconnect floodplains (e.g., remove/set back levees and revetments), including oxbows
and side channels, to restore areas that provide flood storage and slow water during flood
events. Priority should be placed on areas above, below and adjacent to spawning grounds
to counter the increased risk of higher flows scouring spawning areas, as well as to provide
rearing and refuge habitat during floods.
• Remove and fix fish passage barriers such as culverts to ensure fish access to tributaries.
• Continue to work with Seattle Public Utilities to manage the Chester Morse Reservoir to
ameliorate hydrologic impacts, such as low summer flows, in the Cedar River.
• Plant and protect forests in the basin. Work with forestry managers and researchers to
investigate longer stand rotations and selective logging to improve basin hydrology. Studies
have shown that young tree stands (<100 years) actually decrease summer baseflows due to
the water demands of younger trees.
• Study and prioritize areas that need stormwater retrofits, LID, and green stormwater
infrastructure projects, and accelerate those actions in areas important to salmon.

OUR GOALS
aA strategy is a group of actions designed to achieve a goal. As a
a set, the 20 strategies described in this section serve as the primary
D salmon recovery approach in WRIA 8 and are intended to address
a the highest priority stresses on Chinook salmon and support the
key Chinook salmon life stages. The strategies were developed by
0 examining the initial strategies from the 2005 Plan and additional
knowledge gained since 2005, including the key life stages
M identified by the conceptual model of WRIA 8 Chinook salmon,
a the current pressures affecting Chinook salmon survival, and new
° scientific information. WRIA 8 partners were engaged throughout
Z this effort, beginning with a recovery strategies workshop and
followed by numerous discussions with the WRIA 8 TC and WRIA 8
Implementation Committee (IC).
A set of clear strategies based on the most recent and applicable
science is important for effectively guiding salmon recovery actions
in the watershed given limited resources. A full description of each
strategy, including a description of its importance, the negative
impact (or pressure) it reduces, the benefit or improvement sought,
the Chinook salmon lifecycle stage affected, the location in the
watershed where implementation is most relevant, and the specific
actions needed for implementation, is found in Appendix E. Lists
of site -specific projects and land use and education and outreach
actions that implement each strategy can be found in Appendix F,
Appendix H, and Appendix I, respectively.
To the right are the 20 WRIA 8 Chinook salmon recovery strategies,
followed by a brief description of each strategy. The first eight
strategies (in bold font) were identified by the WRIA 8 TC as the
most important for reducing critical pressures on the highest priority
Chinook salmon life stages.

particularly important to prevent,loss of spawning
or rearing habitat, ultimately protecting the spatial
diversity of Chinook salmon in the watershed.
By trapping sediment and filtering pollutants,
functional riparian buffers also reduce the impacts
of nonpoint-source pollution.
®PROTECT AND RESTORE
CHANNEL COMPLEXITY
Complex stream channels provide a
range of habitats necessary for Chinook salmon
spawning, rearing, and survival. They provide
pools and eddies where salmon can rest, feed,
and find refuge from predators and floods. Adding
large wood can improve natural processes for
maintaining or creating pools and riffles and
sorting sediment and gravels, all of which create
the complex habitat that salmon require. Increased
wood loading will improve habitat complexity in
nearly all areas of stream habitat within WRIA 8.
Restoring channel complexity lessens the impacts
of shoreline hardening, altered peak flows due
to impervious surfaces, and increased water
temperature.
®RESTORE SHALLOW -WATER
REARING AND REFUGE
HABITAT
Gently sloping sandy beaches maximize
shallow -water habitat for lake -rearing juveniles
outmigrating to Puget Sound, and can help provide
refuge from native and non-native predators.
Bulkheads or other shoreline hardening and
nighttime lighting affect juvenile behavior in ways
that may increase their susceptibility to predation.
The effects of these changes can be mitigated
in key areas through soft shoreline techniques
and lighting modifications. Shallow -water rearing
and refuge habitats are particularly critical in
Lake Washington south of 190 as lake -rearing
juveniles enter from the Cedar River to rear in and
migrate through the lake, as well as the south end
of Lake Sammamish where juveniles enter from
Issaquah Creek. Improved shorelines throughout
the migration corridor would improve refuge from
predation and provide terrestrial insects for food.
®RECONNECT AND ENHANCE
CREEK MOUTHS
The area where a creek enters a river or lake
provides habitat forjuvenile rearing and refuge
from predators as juveniles migrate to marine
waters. Daylighting or restoring creeks, reducing
their gradient to make them available tojuvenile
salmon, and removing armoring near creek mouths
should restore their ecological function and reduce
the impact of land cover conversion for residential,
commercial, or industrial use, as well as the effects
of predation. All creek mouths are important, but
efforts should prioritize those in the south end
of Lake Washington for rearing and migration to
increase survival of Cedar River juveniles. This
includes enhancing the associated creek delta
habitat.
IPROTECT AND RESTORE
COLD -WATER SOURCES AND
REDUCE THERMAL BARRIERS TO
MIGRATION
Areas of water warmer than about 65 degrees F
can delay migration, diminish spawning success,
and contribute to pre -spawn mortality. While
other strategies help protect and restore cold
water sources (e.g., floodplain reconnection,
riparian cover and forest retention throughout
the watershed), this strategy focuses specifically
on key areas known to be migratory bottlenecks
(e.g., Ship Canal and Sammamish River), or where
problems could develop for other life stages
through climate change impacts. However, high
water temperatures may indirectly exacerbate
other stresses to Chinook salmon (e.g., disease)
as they migrate or rear, ultimately affecting their
survival and/or ability to reproduce. This emerging
issue will be tracked and adaptively managed,
particularly as it affects key life stages. Cold -water
sources will become more important throughout
the watershed for all life stages, notjust migration,
as water temperatures increase.
IMPROVE JUVENILE AND
ADULT SURVIVAL AT THE
BALLARD LOCKS
The primary fish passage barrier in the watershed
is the Ballard Locks, which affects salmon survival
and the timing of adult and juvenile passage into
and out of the watershed. As a legacy land use
impact that forever changed the hydrology of the
watershed, the pressure exerted by the Ballard
Locks can be mitigated but not removed. Measures
to improve fish passage conditions and survival
through the Ballard Locks are of paramount
importance. This strategy focuses on USACE
funding and implementing critical facility upgrades
to ensure effective fish passage and continued
safe facility operation.
REDUCE PREDATION OF
JUVENILE MIGRANTS AND
Predation of juvenile Chinook salmon by native
and non-native species is a long -suspected
issue affecting juvenile survival in the freshwater
system, especially in Lake Washington, Lake
Sammamish, and the Ship Canal. The magnitude
of the problem is not well quantified, and ongoing
research is attempting to clarify the relative impact
of predation on freshwater juvenile survival in
WRIA 8. Additionally, emerging research suggests
that artificial nighttime lighting may alterjuvenile
fish behavior in a way that makes them more
susceptible to predators and increases the length
of time predators actively feed. With improved
juvenile survival, greater numbers of adults are
likely to return, boosting the odds for recovering a
self-sustaining Chinook salmon population.
©REMOVE OR REDUCE IMPACT
' OF OVERWATER STRUCTURES
Removing or reducing the impact of overwater
structures works to alleviate the pressure of
residential and commercial land use along the
lakeshores and migration corridors. This strategy
reduces the effects of docks, piers, pilings, and
other overwater structures that make juveniles
more susceptible to predation, since docks can
provide cover for predators and/or juveniles
will avoid overwater structures and move to
deeper water where they are more susceptible to
predators. The primary purpose of this strategy is
to improve juvenile survival during lake rearing
and outmigration.
REMOVE FISH PASSAGE
HARRIERS
Ensuring that Chinook salmon can access a range
of habitat types is important for all life stages,
but fish passage is not a primary limiting factor in
WRIA 8 for many life stages of Chinook, especially
since the two largest passage barriers that existed
at the time of the ESA listing —the Landsburg
Diversion Dam and the Issaquah Hatchery Intake
Dam —have been addressed. Providing juvenile
Chinook salmon with access to more area for
rearing, especially in small channels where many
fish passage barriers still exist, is important. Also,
ensuring juveniles have access to available cooler
water habitat can mitigate the effects of increased
water temperatures. Removing barriers to fish
passage in Tier 2 areas is important to maintain
the potential for spatial diversity. As development
continues and new roads are built, creek crossings
should be minimized to prevent future barriers,
and new crossings should use bridges or culverts
designed to accommodate fish passage.
r,
" 9PROTECT AND RESTORE
FOREST COVER AND
Retaining forest cover and functional upland
habitat in areas throughout the watershed is
important for water quantity and quality, particularly
to address changes in winter peak flows, summer
low flows, and water temperatures as climate
change progresses. This strategy reduces
the impacts of land conversion, pollutant- and
sediment -filled runoff, and changes in water flow
and temperature. Since implementation of the
2005 Plan, many of the opportunities to purchase
or protect headwater areas have been acted on
or otherwise addressed. Remaining opportunities
are limited but exist along the middle and upper
reaches of Bear/Cottage Lake, Issaquah, Little Bear,
and North creeks. Incentivizing and regulating
retention of forest cover and reforestation on
private lands, as well as reducing impervious cover
through low impact development (LID) practices,
are likely to be effective in indirectly benefiting all
life stages of WRIA 8 Chinook salmon populations.
PROVIDE ADEQUATE
STREAMFLOW
Adequate streamflow is important to provide
habitat during critical rearing and migration stages.
This strategy, intended to address the impacts of
both high and low flows, would reduce the impacts
of land conversion, water withdrawals, increasing
water temperatures, scouring events, and fish
passage barriers. Reducing illegal withdrawals
and protecting or enhancing flows are important
actions throughout WRIA 8, especially in the
Sammamish River basin and its tributaries, and may
become more important in the future, as
climate changes.
RESTORE SEDIMENT
PROCESSES NECESSARY FOR
KEY LIFE STAGES
This strategy addresses two issues — excessive
fine-grained sediments and insufficient spawning
gravel. An excess of fine sediment is a concern
during incubation, when redds/eggs can be
smothered by fine particles. This issue is most
prevalent along Bear Creek/Cottage Lake Creek,
Issaquah Creek, and in all Tier 2 streams. Beneficial
gravels for spawning can be lacking where natural
sediment recruitment processes are interrupted,
such as where levees disconnect the river from
the floodplain on the Cedar River or confluence
areas on other streams are modified. This strategy
reduces the impacts of land conversion, shoreline
hardening, and impervious surface runoff.
RESTORE NATURAL MARINE
SHORELINES
Preventing and removing bulkheads and armoring
along the marine shoreline will allow for a more
natural shoreline with increased overhanging
vegetation, connected drift cells and pocket
estuaries, and increased extent of eelgrass beds
and forage fish spawning habitat. These features
will improve the marine food web function and
increase success of juvenile Chinook salmon
rearing and migrating. The BNSF railway runs along
most of the WRIA 8 marine shoreline, severely
limiting restoration opportunities. However,
any shoreline enhancement or restoration will
offer regional salmon recovery benefits, as
Chinook salmon from other watersheds also rear
in or migrate through the WRIA 8 nearshore.
Opportunities exist to enhance the habitat in front
of the BNSF railway through beach nourishment,
as well as behind or above BNSF through riparian
restoration. Identifying and restoring shoreline
sediment processes are also important to support
habitat for primary Chinook prey species, such as
sand lance and smelt.
RECONNECT BACKSHORE
AREAS AND POCKET
ESTUARIES
Many backshore areas and pocket estuaries have
been disconnected from Puget Sound, resulting
in a lack of tidal inundation and reducing or
preventing access by migrating adult and juvenile
salmon. Along the nearshore, creek mouths
provide important rearing habitat, and recent
research suggests these areas are important to the
overall life history of Puget Sound salmon. Much
of the WRIA 8 shoreline is disconnected from the
Sound by armoring from the railroad prism, but
juvenile salmon need viable rearing and refuge
locations along the shoreline wherever possible.
This strategy will mitigate the effects of the
railroad, perched culverts, and shoreline hardening
in commercial and residential areas.
®PROTECT AND RESTORE
MARINE WATER AND
SEDIMENT QUALITY
Improving marine water and sediment quality
where possible and capping contaminated
sediment in the nearshore, especially near
commercial and industrial areas, may improve early
marine survival directly or indirectly. Additional
research is needed to better understand how
impaired marine water and sediment affect
Chinook salmon early marine survival and the food
web. WRIA 8 will track and adaptively manage
this emerging issue. The strategy will mitigate the
legacy and current impacts of land conversion and
of point and nonpoint source pollution.
IMPROVE WATER QUALITY
"Water quality" is multi -faceted and
intersects with salmon recovery in many ways.
The purpose of this strategy is to support water
quality improvements beyond water quality permit
requirements through encouraging individuals
and jurisdictions to participate in voluntary and
incentive -based programs. Improvements should
target reductions in polluted runoff from impervious
surfaces, nonpoint source pollution, fine sediment
inputs, and altered flows. This strategy is primarily
implemented through education and outreach
programs. Several water quality elements are also
addressed by other strategies in this section (local
and regional planning, regulations, and permitting;
protect and restore cold water sources and reduce
thermal barriers to migration; protect and restore
functional riparian vegetation; and, protect and
restore forest cover and headwater areas). New
regional research is underway to identify possible
impacts of polluted stormwater runoff on Chinook
salmon, and any findings will be adaptively
managed at the local level and in implementation
of the 2017 Plan.
INTEGRATE SALMON
RECOVERY PRIORITIES INTO
LOCAL AND REGIONAL
PLANNING, REGULATIONS, AND
PERMITTING
Local jurisdictions, state agencies, and federal
agencies should consult the WRIA 8 Plan for the
best available science on incorporating Chinook
salmon requirements into required planning for
shorelines, land use, water quality, and project
permitting. The 2005 Plan and this update are
built on the assumption that regulations are
protective and supportive of sustaining salmon
in the watershed; the other strategies articulated
in the plan provide additional ecological efforts
necessary for recovery. While WRIA 8 staff will
not track these actions specifically, or likely fund
capital projects through the process, this strategy
is foundational to the success of others.

Survival Project.
INCREASE AWARENESS OF
AND SUPPORT FOR SALMON
RECOVERY
While most strategies include specific outreach/
education actions to support their implementation,
this strategy is entirely focused on the importance
of raising awareness of and broadening support
for salmon recovery in general. The intent of this
strategy is to ensure watershed -wide awareness
of salmon, agreement on the ecological, cultural,
recreational and economic importance of salmon
in the watershed, and an understanding of
the individual actions that can support salmon
recovery. With a growing human population in the
watershed and many new residents who may be
unfamiliar with Chinook salmon, this strategy is
critical to meeting specific habitat and Chinook
salmon population goals articulated in this plan.

ip
SITE -SPECIFIC PROJECTS a
The 2005 Plan offered a comprehensive approach for salmon habitat
protection and restoration in the watershed through an extensive
list of protection and restoration projects. The original project list
contains actions focused on protecting intact habitat and natural
processes that support salmon, restoring degraded habitat to create
conditions more suitable for salmon, and acquiring land to facilitate
future restoration projects. This suite of habitat projects represents
the actions thought to be needed to effect change in WRIA 8 salmon
populations.
As part of the 2017 Plan, WRIA 8 partners and staff revisited the
2005 project list to ensure the list is up to date and addresses the
current thinking about recovery needs in the watershed. This involved
convening groups of partners by geographic area to evaluate the
2005 project list. Partners provided input to update and refine
existing projects and project descriptions and offered new project
concepts that align with the suite of updated WRIA 8
recovery strategies.
In many cases, the 2005 project list lacked specificity, and an
emphasis of the 2017 Plan is to focus the project list on specific
actions in specific areas. This resulted in removing
many vague project references from the 2005
project list, yet where these concepts remain
important priorities for implementation, they
are carried forward in the 2017 Plan update as
recovery strategies.
The 2005 Plan identified a "Start List" of projects
envisioned as the focus of the first 10 years of
plan implementation. In the absence of quantified
habitat goals, the Start List was developed in part
to measure and track implementation progress.
Now that habitat goals exist— which are a more
effective mechanism for measuring progress than
the number of projects implemented — the Start
List concept has not been carried forward in the
2017 Plan.
In the 2005 Plan and again in the 2017 Plan,
implementation of habitat protection and
restoration projects is a voluntary activity. This is
an important consideration, especially for local
jurisdictions that have other capital priorities for
their limited public resources. Looking forward,
WRIA 8 encourages jurisdictions to explore
multi -benefit approaches to capital project
implementation, whereby habitat restoration is
incorporated into stormwater, drainage, parks,
and other related capital projects and programs.
Grant funders are increasingly recognizing the
value of multi -benefit approaches to project
implementation, which in turn offers an opportunity
to leverage local investments. Additionally, given
that grant resources continue to be insufficient
to achieve recovery objectives, WRIA 8 Salmon
Recovery Council members from partner
jurisdictions are encouraged to prioritize habitat
protection and restoration in local budgets to
the extent practical to accelerate the pace of
implementation and move toward the recovery
goals outlined in this plan.
Please see Appendix F for the full list of
WRIA 8 projects.
Role of mitigation in salmon recovery
The premise of the WRIA 8 Plan's identified
habitat protection and restoration projects and
programmatic actions is to prevent further decline
of Chinook habitat and restore degraded habitat
in order to make significant net improvements
in habitat to address limiting factors and support
recovery. It is clear that simply maintaining status
quo habitat conditions will not restore sustainable,
harvestable levels of Chinook. Land use changes
and associated impacts will continue as the
region's population grows, especially within
urban growth areas designated under the Growth
Management Act, further reducing and degrading
habitat throughout the watershed. It is important
to understand how efforts to address the negative
impacts of development affect WRIA 8 Chinook
salmon habitat protection and restoration.
What is mitigation?
Development projects require permits at local,
state, and/or federal levels, which identify potential
impacts to protected environmental features —
such as wetlands —and species —such as Chinook
salmon. In large measure, the regulatory and
permit process requires avoiding and minimizing
potential impacts as much as possible. When
development activities will create unavoidable
environmental impacts but are allowable under the
existing regulatory framework, project sponsors
are required by regulators to take a defined action
or set of actions to offset or mitigate the impact.
How mitigation works
Mitigation projects can occur on -site (at or near the
development project) or off -site. On -site mitigation
is generally preferable when it is ecologically
feasible and likely to succeed long-term. However,
if mitigation on or adjacent to the development
site is impractical or will not result in meaningful
and sustainable ecological benefits, off -site
mitigation becomes an option under state and
federal rules. One increasingly common option for
off -site mitigation includes purchasing mitigation
credits from a certified mitigation bank or in -
lieu fee mitigation program (e.g., King County's
Mitigation Reserves Program). Mitigation banks
are constructed and certified before impact, and
project proponents purchase credits in the bank
to mitigate for unavoidable impacts. In -lieu fee
mitigation programs first collect impact fees from
development projects and then use those fees to
identify and implement mitigation projects within
an associated service area.
Both mitigation banks and in -lieu fee programs
undergo significant state and federal scrutiny
during their initial establishment and through
ongoing oversight. Mitigation projects only earn
credit when success is proven, and mitigation sites
are monitored and maintained in perpetuity with
funding set aside to ensure projects are completed
successfully. As a result, these off -site, and in some
cases out -of -kind, mitigation options are proving
increasingly effective in improving ecological
functions in areas of a watershed that have been
prioritized for restoration.
Mitigation and salmon recovery
With the establishment of mitigation banks and
programs such as King County's Mitigation
Reserves Program, mitigation funds have become
part of the fabric of funding sources that can
support implementation of habitat restoration
projects. This is especially true in highly urbanized
watersheds, where large development or
transportation projects can create significant
mitigation needs. In some cases, mitigation funding
may be capable of implementing all or portions of a
project identified on the WRIA 8 project list.
The use of mitigation funds to implement habitat
enhancement projects can improve ecological
functions in some areas sooner than may
otherwise be possible by simply relying on grant -
funded restoration or limited local funds.
At the same time, it is important to recognize
that mitigation projects do not represent net
improvements in overall habitat conditions since
each mitigation action is linked to new habitat
impacts resulting from a development action. No
comprehensive and consistent method currently
exists to account for the impacts accrued through
actions that incrementally degrade habitat, water
quality, and hydrologic functions within our
watersheds, not to mention across the broader
region. This conundrum exists even as mitigation
funded projects are helping to implement key
priorities and strategies identified in the
WRIA 8 plan.
Accounting for mitigation in salmon recovery
tracking and reporting
The habitat protection and restoration actions
identified in the 2017 Plan, and the associated
quantitative habitat goals, are meant to represent
net gains in habitat and ecological functions.
Since mitigation is intended to offset impacts
to habitat from various development projects,
habitat enhancements funded through mitigation
do not represent net habitat gains. For purposes
of tracking habitat restoration progress in WRIA
8, we will work with project managers, mitigation
program managers, and other partners to ensure
appropriate accounting for habitat improvements
as well as their associated environmental impacts.
To produce a transparent accounting and reporting
of net progress towards achieving WRIA 8 habitat
goals, WRIA 8 will document which projects,
or portions of projects, were implemented with
mitigation funding.

LAND USE ACTION
RECOMMENDATIONS
In addition to habitat protection and restoration
projects, land use actions are critical to protecting
and restoring habitat conditions for Chinook
salmon and to the success of salmon recovery
in WRIA 8. Land use actions are defined as
policies, rules, or other non -capital actions that
programmatically address habitat protection.
Local governments are responsible for land use
actions, which include planning, regulations,
incentive programs and BMPs that address
landscape features or ecological processes such
as forest cover, road crossings, riparian buffer
conditions, natural flow regimes, and sediment
dynamics. Land use actions determine where and
how urban growth takes place in the watershed,
how stormwater is managed, and the degree to
which environmentally critical and sensitive areas
and functioning habitat processes are protected.
These actions are particularly important to
accommodate a rapidly growing population and
mitigate the effects of a changing climate. Together
with land protection and restoration actions,
land use policies will determine whether salmon
continue to return to our watershed each year.
In many cases, land use actions complement or
support implementation of site -specific project
actions. The 2005 Plan grouped the actions by
geographic subarea (i.e., Cedar River, north Lake
Washington tributaries, Issaquah Creek, and
migratory and rearing areas). For the 2017 Plan,
the list of recommended land use actions was
revisited and updated to serve as a resource for
partners and decision -makers in land use planning
and decisions, and to better focus and guide future
investment of resources to support implementation
of salmon recovery strategies.
See Appendix H for a list of recommended land
use actions organized by land use category.
Growth Management Act
Under the Growth Management Act (GMA),
local jurisdictions must protect critical areas and
designate natural resource lands (e.g., forest,
agricultural, and mineral areas) and urban growth
areas, which identify where urban growth and
development may occur. The 2017 Plan calls for
managing growth in a way that minimizes negative
impacts to salmon. This includes maintaining
existing UGA boundaries, unless altering the
boundary would be beneficial to salmon.
Plan recommendations within UGAs:
• Manage growth to minimize impacts to water
quality, riparian forest cover, and flows
• Promote LID and green stormwater infrastructure
• Use incentive programs to protect watershed
functions and values (examples include transfer
of development rights, public benefit ratings
system, etc.)
• Promote restoring native vegetation cover
Plan recommendation outside UGAs:
• Promote livestock BMPs to protect
ecological functions
Use incentive programs to protect forest
cover and protect and restore riparian buffers
(examples include transfer of development rights,
public benefit ratings system, etc.)
• Ensure maintenance of properties protected
through fee acquisitions or easements
Critical Areas Ordinance
Local governments have critical area ordinances
to protect the natural environment and public
health/safety, including measures to preserve and
enhance "unique, fragile, and valuable elements
of the environment," with special consideration
for actions that preserve or enhance anadromous
fisheries. These regulations have great potential
for achieving salmon conservation objectives,
including:
• Protecting aquatic areas
• Protecting riparian buffers and
nearshore vegetation
• Protecting forest cover
• Protecting wetlands
• Protecting water quality
Shoreline Management Act and Shoreline
Master Programs
A goal of the Shoreline Management Act
(SMA) is to "prevent the inherent harm in an
uncoordinated and piecemeal development of the
state's shorelines' and to facilitate public access
to shorelines of the state. Local governments
are required to develop shoreline master
programs (SMPs), which are the primary means
for administering the SMA. These SMPs include
a characterization of a jurisdiction's shorelines,
including rivers, large lakes, and marine shorelines,
and their associated ecological functions. The
primary overlap between the 2017 Plan and SMPs
is the protection of shoreline forest/vegetation
cover and the protection of vegetated
riparian buffers.
Water Quality and Stormwater Management,
including NPDES Permit
Improving water quality and managing stormwater
are critical for creating and maintaining stream and
water conditions that support salmon survival. In
particular, local jurisdictions are required, under
their NPDES permits, to develop and implement
stormwater management programs to protect
water quality and reduce pollutant discharge.
0
There are at least three areas of strong overlap N
between stormwater management actions and
salmon recovery: LU
1. Regulatory activities — Local government a
partners should implement and enforce NPDES
permit conditions to improve water quality by ,¢u
restoring natural flow regimes. State and local }o
partners need to work together to address
water quality -impaired Tier 1 and Tier 2 streams
with total maximum daily load designations for
a
excessive pollution, temperatures or dissolved
o
oxygen. These actions help address impacts to
salmon in WRIA 8 streams.
Z
2. Incentive -based and voluntary programs —
Local government partners and community
organizations concerned about water
quality can go beyond NPDES requirements
by increasing and promoting stormwater
management structure retrofits, LID, and GSI,
as well as pollutant source control efforts.
stormwater discharge permit requires local
governments to develop public education and
outreach programs. Many of the actions required
by these programs also support salmon recovery.
Groundwater
Groundwater contributes to streamflow and
functions as a coldwater input for many
streams, which is especially needed in streams
affected by high water temperatures. Ensuring
that groundwater is protected and hydrologic
connections are maintained and improved
throughout the watershed is important for
improving habitat conditions for salmon.
The following actions are key:
Encourage LID, GSI and natural drainage systems
to promote groundwater recharge

Floodplain Management
The King County Flood Control District (FCD)
is responsible for managing flood risk along
the County's major river systems, and local
jurisdictions participating in the National Flood
Insurance Program also share flood risk reduction
obligations. In WRIA 8, FCD activities most
commonly overlap with salmon recovery priorities
along the Cedar River and Sammamish River. In
many cases, potential projects to reduce flood
risk are close to or in the same location as habitat
restoration projects, creating opportunities to
collaborate and identify solutions that meet both
flood risk reduction and salmon habitat restoration
goals. In addition to floodplain management on
the Cedar River and Sammamish River, some local
governments also manage floodplains on streams
to reduce flooding and restore habitat.
EDUCATION AND OUTREACH
ACTION RECOMMENDATIONS
Since WRIA 8 is the most populous watershed
in the state, raising public awareness of salmon
recovery, and building and sustaining public
and political will to take action, are imperative if
conditions for salmon are to be improved in the
watershed. Without public and political support
over the long-term, Chinook salmon recovery
efforts cannot succeed, especially as our region
continues to grow.
Outreach and education actions support land use
management and capital projects, or promote
behavior change to improve habitat conditions.
They can apply to a specific location, a particular
target audience, or throughout the basin. The
2005 Plan ranked outreach and education actions
as high, medium, and low priority. To better
prioritize and guide outreach and education
efforts, the 2017 Plan uses the results of WRIA
8 programmatic action implementation surveys
conducted in 2009 and 2015, a 2009 outreach
and education gap analysis, and feedback from the
WRIA 8 Salmon Summit in 2016. This information
provided the basis for a suite of draft outreach and
education actions that were reviewed and revised
at a workshop of education and outreach partners
in 2016.
See Appendix I for recommended outreach and
education priorities.

5. Capture lessons learned and share results
o
The 2005 Plan set a vision for recovery and identified the actions for
implementation. WRIA 8 has adaptively managed the 2005 Plan using
monitoring results, studies and research, and lessons learned from
implementing projects to inform recommendations to the WRIA 8
Salmon Recovery Council for ways to adjust implementation. Progress
reports completed in 2010 and 2015 shared implementation status,
analyzed data, identified challenges, and assessed
recovery assumptions.
The 2017 Plan includes quantitative habitat goals and revised
recovery strategies developed using new information and lessons
learned from the past decade of implementation. The goals
and strategies will improve our ability to adaptively manage
implementation moving forward, help partners work together toward
the same goals, implement the most important actions, and improve
our ability to track and report on our progress. Implementation of the
2017 Plan will be adaptively managed by linking monitoring and new
and emerging information to decision -making through reports and
presentations to the Salmon Recovery Council, and through specific
recommendations from the TC and IC. This approach enables the
Salmon Recovery Council to have a common understanding and
adjust the direction of implementation based on monitoring results
and lessons learned.
In 2017, WRIA 8 developed the MAP (Appendix A) to guide monitoring
c'
and reporting on progress towards implementing recovery strategies
and meeting habitat recovery goals throughout the watershed, to
3
prioritize restoration actions, and to identify gaps. The adaptive
management approach evaluates success in meeting 2017 Plan
habitat goals, and uses triggers to guide future actions or changes
(Table 5). A trigger refers to a threshold of the habitat indicator
that prompts a recommended action. In the case of WRIA 8 habitat
goals, five-year triggers are established to assess
r, whether implementation in on track (i.e., 50% of
0

Adaptive management involves assessing both
indicators associated with project implementation
and the success of land use actions and
education and outreach programs in supporting
implementation of recovery strategies. The
expectation moving forward is that the WRIA
8 TC will regularly review and report data from
monitoring efforts (annually for fish population
data and every five years for habitat condition
data) to assess the effectiveness of restoration
and recovery actions and report to the IC and
Salmon Recovery Council. The WRIA 8 IC will work
with local government and non -governmental
partners to review and assess land use actions
and education and outreach programs at least
every five years to help highlight any changes
that should be considered. The WRIA 8 TC will
track new technology and information on Chinook
salmon, and the monitoring plan will be updated
as needed, pending coordination with the Puget
Sound Partnership to assure consistency with the
Puget Sound Chinook salmon recovery framework.
Assuming the appropriate information is collected
to a sufficient degree to inform decision -
making, the process in WRIA 8 typically involves
discussing monitoring results within the TC
and IC and developing and submitting joint TC/
IC recommendations to the Salmon Recovery
Council for their consideration and action. The
adaptive management process will also affect
how WRIA 8 staff develop their work plans and
assist project sponsors with implementation. This
process will continue to be followed in the future
with continued oversight by the WRIA 8 Salmon
Recovery Council.

APPENDIX A
o Monitoring and Assessment Plan
N A-1. Introduction and background
This document describes the monitoring and assessment activities recommended to oversee
a Chinook salmon conservation and recovery within the Lake Washington/Cedar/Sammamish (WRIA 8)
a watershed. It is intended to be a framework for WRIA 8 staff, partners and practitioners for monitoring
the most important elements to indicate progress in protecting and restoring Chinook habitat in the
,a„ watershed. To the extent practical, it describes monitoring goals and objectives, assessment questions,
0
monitoring design, protocols, staffing needs and costs, and reporting requirements. This plan is
focused on Chinook population and habitat monitoring needed to track Chinook recovery. Its ultimate
function is to provide methods by which users collect and report information to decision -makers on the
progress and pace of Chinook recovery within the WRIA 8 watershed.
This WRIA 8 Monitoring and Assessment Plan (MAP) was informed by numerous prior documents and
efforts, including the WRIA 8 Chinook Salmon Conservation Pion (WRIA 8 Steering Committee, 2005),
Puget Sound Shared Strategy Draft Monitoring and Adaptive Management Plan (PSAMM Steering
Committee, 2007), NOAAs Guidance for monitoring recovery of Pacific Northwest salmon and
steelheod listed under the Federal Endangered Species Act (Crawford et al., 2011), A framework for
the development of monitoring and adaptive management plans (Puget Sound RITT, 2015), Monitoring
habitat status and trends in Puget Sound: development of sample designs, monitoring metrics, and
sampling protocols (Beechie et al., 2017), and the Chinook monitoring and adaptive management
toolkit (Puget Sound Partnership, 2016).
Monitoring and Assessment Plan purpose
The overall goal of the WRIA 8 MAP is to document that actions to protect and restore habitat quantity
and quality within WRIA 8 are performed and adequately contribute to restoring Chinook salmon
viability in the watershed (Figure 1). This plan focuses on freshwater and nearshore habitat under
the jurisdiction of freshwater habitat managers, and includes freshwater Chinook salmon monitoring
performed in the watershed. This plan is intended to address five fundamental questions:
1. Were strategies and actions carried out as recommended? (Implementation monitoring)
2. Did those strategies and actions work as intended? (Effectiveness monitoring)
3. Are overall conditions in the watershed related to Chinook salmon habitat improving? (Habitat
status and trends monitoring — sometimes called cumulative effectiveness monitoring)
4. Do the sum of actions lead to improved Chinook salmon viability? (Chinook status and trends
monitoring)
5. What other technical issues may constitute key constraints to Chinook recovery in the WRIA 8
watershed, and to what degree? (Emerging issues assessment)
NOTE: Other factors, such as harvest and hatchery management, and conditions in the marine
J environment beyond the WRIA 8 nearshore, also affect the trajectory of Chinook recovery. When these
other factors are outside the jurisdiction of WRIA 8 Salmon Recovery Council members, they should be
addressed at the appropriate level — for example, by State and Tribal salmon resource co -managers or
others with jurisdiction.
Monitoring objectives are specific to the assessment questions, geography and life stage, and will be
addressed in greater detail in the following sections.

Description of the watershed area
The WRIA 8 watershed comprises 692 square miles extending from the marine nearshore along
Puget Sound east to the Cascade Crest (Figure 2). Most of the watershed is in western King County;
about 15% extends northward into Snohomish County. It includes two major river systems (Cedar
and Sammamish) and their tributaries, three large lakes (Union, Washington and Sammamish) and
numerous smaller subbasins that drain directly to Puget Sound. The watershed contains two Chinook
salmon populations: Cedar Population (Cedar River and tributaries) and Sammamish Population
(Sammamish River, North Creek, Lake Washington tributaries, Little Bear Creek, Bear/Cottage Lake
Creek, Issaquah Creek, Kelsey Creek).
The watershed is divided into functional "tiers," which denote priority habitat areas for Chinook
salmon. Tier 1 areas are highest priority and include core spawning areas as well as migratory and
rearing corridors. Tier 2 areas include areas less frequently used by Chinook salmon for spawning and
rearing, but are considered important for the long-term geographic distribution of the populations. Tier
3 areas are infrequently used by Chinook salmon, but are still important areas for water quality and
flow management.

Chinook VSP goals. Chinook salmon population recovery goals were determined using the viable
salmonid population (VSP) concept (McElhany et al., 2000). The VSP attributes used to evaluate the
status of Chinook salmon are abundance, productivity, spatial distribution, and diversity. A "viable" r
population is a population that has a negligible risk of extinction over a 100-year time frame.
Recovery goals are set for both a near -term (2025) and a long-term (2055) time frame for each VSP
parameter to support a trajectory toward sustainable, harvestable Chinook salmon populations (Table a
A-1). In 2006-2009, the WRIA 8 Technical Committee worked with resource Co -Managers to reach Q
a
a consensus understanding of habitat, hatchery and harvest conditions and goals' leading towards
recovery of WRIA 8 Chinook salmon. The process resulted in clarification of some of the Chinook w
goals contained in the 2005 WRIA 8 Conservation Plan. These goals were reaffirmed by the WRIA 8
Salmon Recovery Council in 2017. o

Table A-1. WPIA 8 Chinook Salmon Population Goals
Habitat goals. Habitat goals were developed as part of the WRIA 8 Chinook Salmon Conservation Plan
update (2017). These goals focus on key elements affecting critical habitat limitations as determined
by conservation science, and are based on the WRIA 8 conceptual model and pressure assessment n
work performed by the TC in 2015-2016. These goals focus on the most important habitat elementsCN
for conservation and recovery of Chinook salmon in the watershed and are based on local data —
on existing habitat conditions, the unique constraints placed on rivers and streams in the WRIA 8
F
watershed, and the pace of implementation progress in the last ten years. While the number of habitat
o
goals is relatively small, the TC considers them to be proxies for a larger set of expected habitat
a
improvements. It is expected that meeting the short-term and long-term goals for this short list of
habitat elements will result in improvements in other key ecological attributes and contribute to overall

A-2. Monitoring in WRIA 8: Overview
Monitoring for Chinook recovery in WRIA 8 is conducted for three purposes: 1) to determine whether
actions were carried out as recommended (implementation monitoring); 2) to determine whether
those actions produced the expected physical change and/or biological effects, and to share lessons
learned (effectiveness monitoring); and 3) to determine whether the aggregated actions are improving
overall watershed habitat conditions and Chinook VSP (status and trends/cumulative effectiveness
monitoring).
Priority indicators to track WRIA 8 habitat goals
The 2017 Plan includes a short list of goals that focus on the key elements affecting Chinook salmon
within the WRIA 8 watershed. The goals focus on the most important habitat elements for conservation
and recovery of Chinook salmon in the watershed and are based on local data, the unique constraints
placed on rivers, streams and lakes in the WRIA 8 watershed, and the pace of implementation
progress. These goals are proxies for a larger set of habitat processes that the TC hypothesizes will
improve if the goals are met. In order to track progress toward these goals, the following information
should be collected by project implementers and provided to the TC.
1. Acres of floodplain reconnected. Using GIS, measure the area of the Moderate Channel Migratior
Zone previously "disconnected" behind levees or other structures that is now able to interact with
the river. Measure to the nearest 0.1 acre.
2. Wood volume added to stream channel (m3/100 m). Estimate the wood volume added to the stream
channel (methods in Fox and Bolton, 2007).
3. Number of pieces and number of key pieces of wood installed. Count number of pieces and
number of key pieces (methods in Fox and Bolton, 2007).
4. Area of riparian forest planted (to the nearest 0.1 acre) and length of streambank planted (to the
nearest 0.01 mile).
5. Number, location and area of thermal refugia created/restored (square feet, to nearest foot —
Sammamish River and Lake Washington Ship Canal). (Methods to measure thermal refugia as in
Torgersen et al., 2012 and Ebersole et al., 2003.)
6. Length of natural bank profile restored (Lake Sammamish, and Lake Washington south of 1-90
— feet, to nearest foot). "Natural bank profile" is defined by the WRIA 8 Technical Committee as
without bulkhead, with slope and substrate matching historic Iakeshore contours for the area under
restoration.
7. Area of natural riparian vegetation restored within 25 feet of lake shore (Lake Sammamish, and
Lake Washington south of 1-90 — to the nearest 0.1 acre). "Natural riparian vegetation" in this context
is defined by the WRIA 8 Technical Committee as native trees and tall native shrubs.
8. Number and area of pocket estuary habitat (stream mouths) restored in marine area (square feet,
to nearest foot, or acres to the nearest 0. 1 acre).
Reporting interval: five years
Information on progress for all strategies and habitat goals should be reported to the Salmon Recovery
Council every five years, beginning in 2020.

Technical and Implementation Committees, with assistance from WRIA 8 staff. Where feasible, the
objective is to use standard reporting metrics as in Habitat Work Schedule (HWS) or Pacific Coastal
Salmon Recovery Fund (PCSRF) requirements.
Cost
Cost of information gathering should be integrated into standard project reporting protocols. Summary
reporting will be incorporated into WRIA 8 team work program.
A-3. Implementation monitoring
Assessment questions: Were Chinook recovery actions carried out as recommended? Are
we performing actions at the recommended pace?
The purpose of implementation monitoring is to assess whether activities were carried out as planned.
Typically, implementation monitoring is performed using information reported by project or program
managers. Implementation monitoring also documents whether Best Management Practices were
implemented as planned (for example, for water quality or stormwater projects, or riparian plantings).
Implementation monitoring indicators
In order to report progress toward recovery at the watershed level and regionally, WRIA 8 tracks
implementation using the state's Habitat Work Schedule (HWS) database. This tool contains an
extensive list of implementation tracking metrics intended to capture progress on a wide variety of
salmon recovery actions. In addition to being a tool for watersheds to track their local activities, HWS
is used by the Governor's Salmon Recovery Office and Washington Recreation and Conservation
Office to report to NOAA as required by agreement under the Pacific Coastal Salmon Recovery Fund
(PCSRF).
The universe of metrics in HWS is vast, and WRIA 8 has identified a subset of indicators for tracking
implementation of the highest priority recovery actions needed in our watershed. These indicators
align very closely with the recovery strategies approved by the WRIA 8 Salmon Recovery Council in
2017, which are designed to address the most significant factors limiting Chinook recovery.
Strategy implementation
Table A-3 lists the recovery strategies used to recover Chinook salmon in WRIA B. The first eight
strategies address the highest priority pressures on the most critical life stages and are considered the
highest priority (highlighted in bold font). Project partners should —at a minimum —track implementation
using the indicators outlined in the table below. Grant recipients may be asked by funders to provide
additional implementation information, and where such information is being developed for other
reporting purposes, WRIA 8 should receive that information as well.

Implementation monitoring should be reported by individual project managers, and compiled by WRIA

Adaptive Management trigger(s)
Adaptive management actions are recommended in 2020 if priority implementation goals are not
being met, or if strategies are not being implemented. The Technical and Implementation Committees
will examine the pace of overall implementation and make recommendations to the Salmon Recovery
Council. This will include an assessment of the reason for not being on pace, and a reassessment
of priority strategies, given new knowledge on key constraints and life stages based on an updated
WRIA 8 conceptual model. The adaptive management approach evaluates success in meeting 2017
Plan habitat goals, and uses triggers to guide future actions or changes (Table A-4). A trigger refers to
a threshold of the habitat indicator that prompts a recommended action. In the case of WRIA 8 habitat
goals, five-year triggers are established to assess whether implementation in on track (i.e., 50% of the
way toward implementation of the 2025 goal).

A-4. Effectiveness monitoring
Assessment question: Did actions work as intended?
b Effectiveness monitoring evaluates whether the specified activities had the desired effect — i.e., it
monitors outcomes. It would answer questions such as, "Did the riparian planting project create
effective shade cover?" or, "Did the floodplain reconnection project increase the amount of low-
o velocity edge habitat at flood flows, and are the new habitats being used by Chinook?" or, "Did the
a Critical Areas policy meet its goal of no net loss of shoreline habitat?"
a Effectiveness monitoring can be applied to a strategy, a restoration project, an outreach and education
} program, or a policy action. For restoration projects, effectiveness monitoring used in this context
o is at the spatial scale of the project — i.e., effects are usually measured at the project site. Strategy,
— program or policy effectiveness monitoring, where outcomes may be more diffuse, may be designed
at a different scale. For example, an education program might investigate whether the program had
a the desired effect on behaviors or attitudes related to habitat protection in a particular city, or on a
demographic throughout the watershed.
Specific effectiveness monitoring requirements should focus on projects where outcomes are
uncertain, and should be based on the objectives and performance standards of the action. For
instance, a floodplain reconnection project intended to increase shallow -water edge habitat at five-
year flood flows by 50% over pre -project conditions would measure the amount of edge habitat
gained by the project under those conditions, compared to the prior amount. Ideally, the project
would also compare its before -and -after results to an appropriate local standard (control), or use
another appropriate study design (Ron!, 2005). For projects with a hypothesized but uncertain direct
effect on Chinook salmon, monitoring that effect (i.e., before -and -after snorkel monitoring) is strongly
recommended. In many cases, a Before -After -Control -Impact (BACI) design is optimal (Roni, 2005).
Effectiveness monitoring plans should answer the following management questions (PSAMM Steering
Committee, 2007):
• What is the hypothesis supporting the action?
• What are the expected physical and biological changes and time frames for these changes?
Effectiveness at a larger programmatic or watershed scale is often captured as "cumulative
effectiveness" or status and trends monitoring, discussed in the next section.
Specific guidance for all circumstances is beyond the scope of this document. However, good sources
of information include the Pacific Northwest Aquatic Monitoring Partnership website at https://www.
monitoringresources.org/Resources/Home/Index. Field methods for effectiveness monitoring are
also described in Tetra Tech, 2014. WRIA 8 has created a website with links to relevant monitoring
documents at http://www.govlink.org/watersheds/8/reports/default.asDx#tech. See also effectiveness
monitoring information funded by the Washington State Recreation and Conservation Office at
http://www.rco.wa.gov/doc—pages/othe[..pubs.shtml#monitoring.
3 Project effectiveness
Guidance on study design and field methods can be found in Roni, 2005 and Tetra Tech, 2014.
J Another important resource summarizing the research literature on fish -habitat relationships and the
effectiveness of common restoration actions is Roni et al. (2014)
Policy and Program effectiveness
Examples of programmatic effectiveness monitoring include WRIA 8-funded outreach and education
programs like Beach Naturalists, Cedar River Salmon Journey, and Stewardship in Action. Monitoring
the effectiveness of policies and programs related to land use is not yet extensively developed in
WRIA 8. One notable exception is a study assessing the effectiveness of Critical Areas rules in rural
King County (Lucchetti et al., 2014). Other useful guidance for policy and plan effectiveness monitoring
can be found online, e.g., www.gualityplanning.org.nz.
Priority effectiveness metrics
Effectiveness metrics depend on the action being implemented, and should be selected to monitor
whether project outcomes are being achieved. High -impact projects with greater uncertainty are
highest priority for effectiveness monitoring. A large body of literature exists documenting the
effectiveness of many common restoration techniques (Boni et al., 2014). Projects with uncertainty
around outcomes related to fish use are highest priority. The TC has identified the following project
types as priorities for effectiveness monitoring:
Instream habitat enhancement (based on placement of structures such as large woody debris,
boulders, other hydraulic or cover elements)
o Wood loading in Bear Creek and Issaquah Creek and elsewhere
Shoreline restoration (specifically lacustrine and marine nearshore beach nourishment or bank
restoration)
Over -water structures (including dock modifications)
Floodplain reconnection (including river levee setbacks and specifically the effectiveness of off -
channel habitats)
o Sammamish side channel reconnection and fish use
• Thermal refuge creation and other projects designed to lower water temperatures
• Water quality enhancement (e.g., effectiveness of project or outreach BMPs, stormwater retrofits for
quality control, temperature and dissolved oxygen control, and other treatment targeting reduction in
metals, nutrients, and other constituents)
• Management of exotic species of flora and fauna
• Predator control
• Use of herbicides on aquatic species (where the goals of these projects target effects on salmon)
and impacts of aquatic invasives on migration
Note: The Project Subcommittee may work with TC to recommend monitoring to projects with greater
uncertainty of outcomes.
Reporting interval
b Effectiveness monitoring reporting intervals vary depending on the activity, but reporting often occurs
at the project 2, 5, and 10-year mark, or after significant events (e.g., a 10-year flood). The Technical
w Committee will review reports and make adaptive recommendations as needed.
nCollected/reported by:

u A-5. Habitat status and trends monitoring
°D Assessment question: Are salmon habitat conditions in the watershed improving or
a
declining?
a Habitat status and trends (S&T) monitoring tracks and reports on overall watershed health. Because it
Nis designed to provide a reliable picture of watershed habitat condition over time, it must collect key
vinforMntinp thro, Oh t thQ xuatarshed in A Qygtomnlor and rigorous manner
NOTE: Habitat status and trends monitoring currently is un-funded in WRIA 8. The recommendations
presented in this section provide a framework for future habitat status and trends monitoring in WRIA 8
when funding or partnership opportunities with other monitoring agencies allow.
v S&T Monitoring Purpose
V
o The purpose of S&T monitoring is to assess the overall condition of stream and riparian habitat along
salmon streams in the WRIA 8 watershed over time, to inform adaptive management of the WRIA 8
Plan. It is intended to examine whether the sum of actions are leading to a net improvement in habitat
3 conditions in the watershed. As such, S&T monitoring takes a watershed -scale approach.
m
J The efficient use of limited monitoring resources requires WRIA 8 to work with partners and to rely on
_ a small set of indicators to represent watershed health for salmon recovery. Much useful information
requires only gathering and reporting information collected by other agencies (e.g., WQI, B-IBI). Table
A-5 summarizes the indicators proposed by the TC and their relationships to WRIA 8 salmon recovery
goals and strategies.

Management questions:
1. Status: What is the condition of streams, rivers and lakes in WRIA 8 based on common attributes?
2. Trends: Are conditions of streams, rivers, and lakes changing overtime?
S&T Monitoring Elements
The WRIA 8 S&T program is comprised of two elements: 1) a field component; 2) a remote -sensing and
GIS component.
Field -based S&T monitoring
The WRIA 8 wadeable streams element of field -based monitoring will follow the design and methods
used in the King County/WRIA 8 Status and Trends Monitoring Project (King County, 2015). The non -
wadeable elements (rivers and lakes) will follow other methods, detailed below.
Study area. Wadeable streams, and rivers and lakes used by salmon in the Lake Washington/ Cedar/
Sammamish (WRIA 8) watershed.
Study design. For the wadeable streams portion, the TC recommends re -sampling the study sites used
in the 2010-2013 King County/WRIA 8 status and trends project (King County, 2015). This project used
a Generalized Random Tessellation Stratified (GRTS) design, which can produce a spatially balanced
probability -based survey design (Stevens and Olsen, 2004; Olsen et al., 2012). Because this survey
design is spatially balanced and probabilistic, it can be used to extrapolate the observed metric values
from the relatively small number of sites sampled to the larger population. In 2009-2010, King County
and WRIA 8 established 50 sampling locations on Tier 1, 2 and 3 streams throughout the watershed;
these sites were selected from the Washington Master Sample and sampled annually from 2010-2013.
The TC recommends continuing to monitor these established sites.
For the rivers and lakes portion, the TC recommends a full longitudinal survey of the Cedar
(downstream from Landsburg) and Sammamish rivers, the entire Lake Sammamish shoreline, and the
Lake Washington shoreline (including Mercer Island) south of the Interstate 90 bridge.
Sampling frequency. The TC recommends annual sampling for the wadeable streams portion. For
replicated metrics with medium to high precision, reasonably high power to detect moderate levels of
change (i.e., from 1 to 3 percent per year) is generally not achieved until 10 or more years, if sampled
annually (Larsen et al., 2004; King County, 2015). Sampling less frequently would impede the ability to
detect change for 20 or more years.
The rivers and lakes surveys should be performed every five years to inform reporting and adaptive
management. Initial results should be reported in 2020; therefore, field work should be completed by
2019 or earlier.
Sampling protocol and quality assurance. The TC recommends using the Washington Department of
Ecology Protocol for Wadeable Streams (WDOE, 2009), as outlined in the WRIA 8 Wadeable Streams
Status and Trends Project (King County, 2015). Data storage and analysis is significantly streamlined by
using electronic based data collection forms and transmitting the electronic information directly into
the Ecology Environmental Information Management (EIM) System.
River wood volume surveys can use either the Ecology protocol for wide streams and rivers
(WDOE, 2010) or another approach, e.g., as outlined in the PSP Chinook Monitoring and Adaptive
Management Toolkit (PSP, 2016).
The lake surveys (linear feet of natural shoreline) will use methods as in Toft et al. (2003).
For wadeable streams, data collection and storage should follow guidelines for the Ecology EIM.
Consult the WRIA 8 S&T project documentation (King County, 2015) for details. Rivers and lakes data
will be maintained in Excel spreadsheets by the WRIA 8 Technical Coordinator. Wadeable streams
metrics will include measures of the components of variance and levels of precision. Cumulative
distribution function (CDF) plots will be used to quantify metrics extrapolated over the target sample —
frame (refer to the S&T project report for methods).

00
Remote sensing and other data
WRIA 8 relies on aerial photographs and data products acquired from other agencies to monitor status
and trends of land cover and water quality in the watershed. Most GIS analysis can be performed
by King County under existing work programs in its capacity as service provider to the WRIA 8 SRC.
High -resolution land cover data using 2015 aerial photography were provided to some Puget Sound
counties (NOAA, 2017), and should be available at five-year intervals from NOAA. Some products or
analyses may need to be purchased in the future.
Priority remote sensing and other metrics
Priority metrics for status and trends of remotely sensed data should follow regional guidelines and
protocols where available. The TC recommends that the following information be collected: 1) Forest
cover (NOAA High Resolution Land Cover); 2) Floodplain area (King County GIS); 3) Water Quality Index
for WRIA 8 WO stations (King County Streams Monitoring Website); 4) Benthic Index of Biotic Integrity
scores for WRIA 8 streams (King County Ambient Monitoring Program).
Riparian forest cover
Management question: What is the extent of forested riparian cover along streams and lakes in the
watershed? Is riparian forest cover increasing or decreasing, and at what rate?
Geographic extent: All Tier 1 and Tier 2 salmon streams in WRIA 8, Lake Washington and Lake
Sammamish.
Data sources
• NOAA Coastal Change Analysis Program High -Resolution Land Cover and Change (C-CAP; 2015
coverage in process — to be updated every five years starting in 2020): (GIS coverage)
• Local streams GIS layer (county data — also should have coverage that depicts anadromous (salmon)
streams.
• Other local datasets (e.g., Urban Growth Area boundaries, jurisdictional boundaries, zoning)
Methods
1. Extract land cover into GIS and clip to watershed boundary.
2. Load appropriate stream layer into GIS with other relevant local datasets.
3. Create a 200' buffer around the anadromous stream layer. (NOTE: Other widths, e.g. 50' etc., may
be informative.)
a. For Lake Washington and Lake Sammamish, create a 25' buffer around the lake shoreline (Lake
Washington south of Interstate 90 and entire Lake Sammamish)
4. Compute the total area inside the buffered area for each stream/lake. Compute the total area
classified as "Forest"
5. Calculate % of forested land cover for each stream/lake: %forested area = (forested area/total area)
x 100.
Reporting interval
Information should be assessed and reported in five year intervals, as land cover data become
available from NOAA.

Area of connected floodplain
Management question: What is the area of floodplain connected to its channel? Is connected
floodplain area increasing or decreasing, and at what rate?
Geographic extent: All salmon streams with mapped floodplains in WRIA S.
Data sources
• King County Rivers GIS layer
• King County Channel Migration Zone GIS layer (or mapped floodplain layer if CMZ is not mapped)
• King County flood facilities GIS layer (i.e., levees, revetments etc., including private facilities)
• Local roads GIS layer
• Local aerial photography in GIS
NOTE: This metric depends upon accurate mapping of flood control facilities, including private
facilities. Mapping should involve periodic field updates. In WRIA 8, a field survey of private flood
facilities was last completed in 2015.
Methods
1. Load appropriate mapping and floodplain (CMZ) layers into GIS with other relevant local datasets.
Load flood facilities and roads layers. o

Water Quality Index (WQI)
Y
WQI is a unitless number from 1 to 100 that integrates annual stream water quality monitoring data
for temperature, pH, fecal coliform bacteria, dissolved oxygen, total suspended sediment, turbidity,
total phosphorus, and total nitrogen into a single score. Constituents are combined and results are
aggregated over time to produce a single score for each sample station. Stations scoring 80 and
above generally meet Ecology expectations for water quality and are of "lowest concern," scores 40
to 80 indicate "marginal concern," and water quality at stations with scores below 40 do not meet
expectations and are of "highest concern" (WDOE, 2002). Scores can be acquired from the King
County Water Quality monitoring unit: http://green2.kingcounty.gov/streamsdata/wgl.aspx.
Because WQI integrates a number of important water quality metrics, it is a useful tool for tracking
overall water quality over time. However, since the metric integrates many constituents into a single
score, the information may not be enough to indicate specific adaptive management responses.
Nevertheless, WQI can indicate whether the sum of actions in a stream basin are sufficient to maintain
or improve water quality. Therefore, the TC recommends collecting and reporting the WQI to the SRC.
Reporting interval
Information should be assessed and reported at five year intervals.
Collected/reported by
WRIA 8 TC.
Reporting format
WRIA 8 TC will produce a memo indicating WQI status and trends to the WRIA 8 SRC.
Benthic Index of Biotic Integrity (B-IBI)
Like WQI, B-IBI is a unitless number from 1-100 that integrates a number of components into a single
score to compare the biological condition of streams. Sites scoring 80 and above are considered in
"excellent" condition, scores from 60-79 are "good," 40-59 are "fair," 20-39 are "poor," and 0-19 are
"very poor." (PSSB, 2017). Scores can be downloaded from the Puget Sound Stream Benthos website:
http://www.pugetsoundstreambenthos.org/.
Because B-IBI integrates a number of metrics indicating biological condition, it is a useful tool for
tracking the overall biological health of a stream system. However, since B-IBI integrates many
constituents into a single score, the information does not lend itself to providing specific adaptive
management recommendations. Nevertheless, like WQI, B-IBI can indicate whether the sum of actions
in a stream basin are sufficient to maintain or improve water quality. Therefore, the TC recommends
collecting and reporting B-IBI to the SRC.
Reporting interval
Information should be assessed and reported at five year intervals.

A-6. Chinook salmon status and trends monitoring
Assessment question: Do the sum of actions lead to improved Chinook salmon viability?
Chinook salmon status and trends monitoring in WRIA 8 generally consists of state efforts augmented
by grant -funded assistance from WRIA 8 partners. In that context, WDFW and partners annually
conduct Chinook spawner surveys (redd count method) on all Tier 1 and 2 streams, and juvenile
outmigrant trapping on Bear Creek and the Cedar River,
Abundance: Annual spawner surveys are conducted on all streams with regular Chinook spawning
(Cedar River and its tributaries, Bear/Cottage Lake, Issaquah, Little Bear, North, Kelsey, May, and
Coal creeks). Trained crews survey each stream weekly during the spawning season (Cedar River is
surveyed more frequently). Method of deriving abundance estimate for all streams except the Cedar
River is Area -Under -the -Curve. For the Cedar River population, surveys via inflatable raft and foot
are performed at least weekly for the entire portion of the river and tributaries accessible to Chinook
salmon, and up to three times per week during the peak spawning season. The survey is considered
a census of the complete river, though redd detection efficiency is acknowledged to depend on
light conditions, flow level and turbidity (Burton et al., 2016). Adult abundance on the Cedar River is
estimated by a redd expansion factor of 2.5 fish per redd (WDFW, 2017). Proportion of natural -origin
spawners (PNOS) is estimated from weekly carcass surveys to detect the presence or absence of
adipose fins or coded wire tags.
Juvenile abundance is calculated for the Cedar River and Bear/Cottage Lake Creek byjuvenile
outmigrant trapping conducted annually by WDFW (Kiyohara, 2016).
Productivity: Adult -adult productivity is computed by two methods. WDFW calculates productivity
annually using PNOS and age data collected during carcass surveys on Bear Creek and the Cedar
River, combined with run reconstruction methods using FRAM modeling (Bosworth, personal
communication). In its 2015 status review of Chinook salmon, NOAA estimated the productivity as the
trend of the log of the smoothed natural -origin spawning abundance in year t minus the smoothed
natural spawning abundance in year (t-4), where results below zero indicate populations below
replacement (NWFSC, 2015).
Juvenile productivity is measured by the number of juvenile migrants from Bear Creek and the Cedar
River produced per female spawner that contributed to the outmigrating brood year (Kiyohara, 2017).
Average fecundity is assumed to be 4,500 eggs per female. Two life -history forms of sub -yearling
Chinook salmon are observed in WRIA 8: small fry migrating immediately after emergence, and larger
parr that rear in freshwater for some time (usually one to three months) before migrating. Because the
survival rate of parr migrants is unknown, an overall juvenile survival rate is calculated combining both
fry and parr migrants and reported annually (Kiyohara, 2017).
Distribution: WRIA 8 calculates the spatial distribution of Chinook salmon in the watershed by
conducting annual spawner surveys on all Tier 1 and Tier 2 Chinook spawning streams in the
watershed.
Diversity: Carcass surveys are performed at least weekly during the spawning season on Bear Creek
and the Cedar River to estimate the proportion of hatchery -origin Chinook spawners (PHOS) in WRIA
8 streams. Scales are collected from carcasses to determine the age distribution of returning Chinook.
Ages are estimated by WDFW staff using the Gilbert -Rich system (total age of the fish with freshwater
age as the subscript).
Reporting interval
Status is reported to the WRIA 8 SRC during annual presentations. Trends are reported to the SRC at
approximately five year intervals.
Collected/reported by
The WRIA 8 TC compiles reports and other information from partner agencies.
Reporting format
Annual presentations to WRIA 8 SRC and five-year written reports.
Cost of Chinook status and trends monitoring
Chinook status and trends monitoring is currently funded through grants and partnerships between
King County, Seattle, Bellevue, Redmond, USACE and WDFW. Juvenile outmigrant trapping at Bear
Creek and the Cedar River and associated reporting, including PIT tagging, detection and reporting
at the Ballard Locks, costs approximately $340,000 per year (cost to be updated to include USACE
contribution). Adult spawner surveys of all Tier 1 and Tier 2 streams in WRIA 8 costs approximately
$XXX,000 per year. [cost information to be added]

A-7. Emerging issues assessment
In 2015, WRIA 8 hosted a technical forum assembling fisheries scientists and technical experts in
salmon recovery issues in the watershed. Participants proposed the following priority -level rankings
of limiting factors to recovery. These constitute an outline for a prioritized science agenda to advance
recovery and support implementation of the 2017 Plan. (A full summary of the forum and presentations
can be found online at http://wwwgoviink org/watersheds/8/committees/l5TechFrm/default.aspx )
First -tier priorities:
Ballard Locks and Ship Canal operations — effects of high temperature, low dissolved oxygen, and
concomitant decreased resistance of salmonids to disease/parasites
Rearing and refuge — lack of woody debris and floodplain connectivity (levees, revetments) and other
features of adequate instream rearing habitat
Lake survival — especially the effects of artificial light and predation (predation in Ship Canal may be
a key limiting factor)
• High water temperature — especially in the Ship Canal and Sammamish River
Other important priorities:
• Water quality — stormwater, toxic loading of phthalates, and dialysis drugs; are current stormwater
regulations and treatment standards adequate?
• Streamflows — both winter and summer
• Invasive aquatic vegetation
Other limiting factors with potentially large impacts:
• Piers and docks
• Genetic introgression or other issues related to hatchery operations
In addition, the WRIA 8 TC identified the following critical monitoring needs to track indicators
associated with key recovery goals:
• Juvenile outmigrant trapping
• Spawner surveys
• Wood volume surveys on all Tier 1 and Tier 2 streams
• Lakeshore surveys: length of natural bank profile, bulkheads, overwater structures
• Remote sensing: high -resolution land cover mapping of forest cover and impervious surfaces
• Assessment of pocket estuaries and coastal streams entering Puget Sound

Plan Update Process
In developing the 2005 Plan, the WRIA 8 Salmon Recovery Council set an initial 10-year time horizon
0
N
for implementation, with the expectation that the plan would be updated after 10 years. To initiate the
—
plan update process, WRIA 8 hosted a watershed summit in early 2016, convening salmon recovery
LU
partners to report on 10 years of progress implementing the 2005 Plan, share the status of Chinook
o
salmon recovery, re -energize partners for the next phase of recovery work, and discuss emerging
Z)
challenges and opportunities. Following the summit, the TC developed a new Chinook salmon life
a
stage conceptual model to better identify when and where in the watershed certain human pressures
}
have the greatest impact on Chinook salmon survival and to highlight the resulting priority life stages
on which to focus recovery strategies and actions. The TC then rated the human pressures on Chinook
—
salmon survival to identify the pressures that pose the greatest threat to recovery (referred to as the
m
"pressures assessment"). In a series of workshops, the TC and WRIA 8 Implementation Committee
a
(IC) used the conceptual model and pressures assessment to develop a set of 20 new and revised
o
recovery strategies that guide implementation of recovery actions.
Concurrent with developing the strategies, the TC reviewed the Chinook salmon population recovery
goals from the 2005 Plan. The TC recommended, and the Salmon Recovery Council approved,
retaining the existing Chinook salmon population recovery goals. The TC and the IC then developed
a suite of habitat restoration goals for the most important WRIA 8 habitat. The 2017 Plan also
describes the adaptive management approach that guides how we track and report progress towards
implementing recovery strategies and goals. During the plan update process, roughly February 2016
to September 2017, the TC and IC were heavily engaged in developing and reviewing elements of
the 2017 plan. The Salmon Recovery Council received regular updates at bimonthly meetings, and
made decisions on elements of the 2017 Plan at key milestones, such as approving Chinook salmon
population recovery goals, recovery strategies, and habitat goals (Figure B-1).

APPENDIX C
WRIA 8 Pressures Assessment
During the Plan update process, the WRIA 8 Technical Committee (TC) estimated the intensity of the
most important known sources of human -caused stress to Chinook salmon and salmon habitat in the
WRIA 8 watershed. This "pressures assessment" was based on current scientific research and local
knowledge of conditions in each habitat used by Chinook salmon. The pressures assessment rated the
scope, severity and irreversibility of each important stressor to Chinook salmon at each life stage and
habitat component for both WRIA 8 Chinook populations. These ratings were entered into a regional
conservation planning tool (Miradi) to create a summary that constitutes thejudgement of the TC on the
relative impacts of each stressor to Chinook salmon in the watershed.
The WRIA 8 pressures assessment began with the list of 47 stressors developed by the Puget
Sound Partnership as part of the effort to create a common regional 'language' for Chinook and
Puget Sound Recovery (PSP, 2014). As part of what was known as "Phase 1" of a PSP-led Monitoring
& Adaptive Management process, the TC first classified each stressor on a scale of 1-5 (5 denoting
the highest negative impact). With a few exceptions, stressors that were classified below 2.5 in the
2014 assessment were not carried forward for further prioritization. A few others, noted below, were
combined to simplify the assessment. This initial filtering and combining process reduced the total
number of stressors subsequently assessed to 35.
The TC concurrently developed a life -cycle based conceptual model, and incorporated that knowledge
into the pressures assessment by considering each stressor in relation to each life stage of both
populations. This approach is somewhat aligned with WDFW's approach to managing species based on
life stages and life -cycle modeling in the Columbia Basin and elsewhere. With this approach, estimates
of impacts were focused on the specific locations used by Chinook salmon in WRIA 8 during the
specific times and life stages Chinook occupy them.
Next, the TC reviewed the links between stressors and components (Chinook habitats and life stages
for each population), and rated the impact of each stressor on each component. The pressures
assessment rated each stressor/component pair low, medium, high, or very high in terms of scope,
severity and irreversibility according to regional definitions (see below). (If a stressor was hypothesized
to have no impact on a particular life stage, the component pair was not rated.) Note that a score of
low or medium is not meant to convey that the pressure is unimportant, but rather that relative to other
pressures, it is not the most widespread or severe for that life stage.
Life Stage Components Used for Rankings
The following life stages match those identified in the conceptual model, which represents the basis of
TC assumptions and working knowledge of Chinook in WRIA 8. The two WRIA 8 Chinook populations
were rated separately due to their different experiences in the watershed.

Pressure Rating Definitions
SCOPE: Most commonly defined spatially as the proportion of the habitat component (life stage +
v
geography) that can reasonably be expected to be affected by the pressure within ten years given
U
the continuation of current circumstances and trends. For ecosystem and ecological communities,
o
measured as the proportion of the component's occurrence.
E
m
Low: The pressure is likely to be very narrow in its scope, affecting the component across a small (1-
o
10%) proportion of the area/population.
0
Medium: The pressure is likely to be restricted in its scope, affecting the component across some (-11-
U
30%) of the area/population.
<
The pressure is likely to be widespread in its scope, affecting the component across much (-31-
70%) of the area/population.
a
v
Very High: The pressure is likely to be pervasive in its scope, affecting the component across all or
v
most ('71-100%) of the area/population.
SEVERITY: Within the scope, the level of damage to the component from the pressure that can
reasonably be expected given the continuation of current circumstances and trends.
E
E
Low: Within the scope, the pressure is likely to slightly degree/reduce the component or reduce its
E
population by -1-10% within ten years or three generations.
Medium: Within the scope, the pressure is likely to moderately degrade/reduce the component or
V
reduce its population by ^'11-30% within ten years or three generations.
o
Within the scope, the pressure is likely to seriously degrade/reduce the component or reduce its
0
__
population by-31-70% within ten years or three generations.
3
Very High: Within the scope, the pressure is likely to destroy or eliminate the component or reduce its
s
population by-71-100% within ten years or three generations.
0
IRREVERSIBILITY (PERMANENCE): The degree to which the effects of a pressure can be reversed
and the component affected by the pressure restored
o Low: The effects of the pressure are easily reversible and the component can be easily restored at a
relatively low cost and/or within 0-5 years.
F Medium: The effects of the pressure can be reversed and the component can be restored with a
o reasonable commitment of resources and/or within 6-20 years.
a
I iigh: The effects of the pressure can technically be reversed and the component restored, but it is not
w practically affordable and/or within 21-100 years.
r,
o Very High: The effects of the pressure cannot be reversed and it is very unlikely the component can
— be restored, and/or it would take more than 100 years to achieve this.
Results:
The summary results are shown in Table 1. The rating for each pressure to component pair is
performed in Miradi using an algorithm to weigh scope, severity and irreversibility. A rating of Low,
Medium, High or Very High is assigned to all relevant relationships (a blank cell indicates no significant
relationship is hypothesized between the pressure and life stage). The TC highlighted high or very high
pressures for the most important life stages to address first.
Climate impacts are reflected in the results. By considering altered peak flows, temperatures and
predation, which are predicted to be exacerbated in WRIA 8 by continued climate change, the ratings
reflect current and predicted worsening through the severity and irreversibility ratings.
The life stages identified for the WRIA 8 Chinook Recovery Plan update process as the highest priority
are lake rearing, stream rearing, and migration (both downstream migrants and returning adults).
The high and very high pressures for each priority life stage were summarized and were presented
to a workshop of WRIA 8 TC and Implementation Committee (IC) members in August of 2016. The
joint workshop analyzed the current recovery strategies in relation to the pressures and developed
new strategies where needed. Some pressures were only relevant or highly rated for one of the
populations; therefore, strategies have a geographic specificity reflected in the recovery strategies and
associated actions.
At a high level, the pressures assessment process and workshops confirmed the following pressures
as most important to address in WRIA 8 for Chinook salmon recovery:
• Land conversion
• Levees
• Shoreline armoring
• Altered peak flows
Increased water temperatures
Predation (native and non-native species)
Ballard Locks (fish passage)

4. Nearshore (Pocket estuaries/stream mouths)
a HABITAT GOAL SETTING APPROACH
The relationships between habitat conditions and Chinook salmon growth and survival are multifaceted
and complex, and operate at many spatial and temporal scales. Chinook population -level responses
to even large-scale habitat improvements may not be detectable for years, and may be confounded
v by improvements or declines elsewhere in the watershed or in the marine environment. Nevertheless,
known linkages exist between freshwater habitat and salmon, backed by decades of credible research.
The WRIA 8 Technical Committee selected a short list of goals (Table 1) that focus on key elements
affecting critical habitat bottlenecks as determined by conservation science, and based on the 2016
WRIA 8 conceptual model and pressures assessment. These goals focus on the most important habitat
elements for conservation and recovery of Chinook salmon in the watershed and are based on local
data on existing habitat conditions, the unique constraints placed on rivers and streams in the WRIA 8
watershed, and the pace of implementation progress in the last ten years. These goals are ambitious
but feasible within the framework of current conditions.
t Coal and May Creeks were classified as Tier 3 streams in the 2005 Chinook Plan. They have experienced a
recent increase in use by spawning Chinook salmon and contain areas with somewhat higher -quality habitat
compared to some other Tier 2 areas. The Technical Committee will continue monitoring their status, and
consider upgrading to Tier 2 if spawning continues to increase.

While the number of habitat goals is relatively small, the Technical Committee considers them to
be proxies for a larger set of expected habitat improvements. Some of these multiple benefits are
described in the notes accompanying the goal narratives.
Monitoring is necessary to track progress toward these goals (See Appendix A). Reporting will occur
at five-year intervals. To align with other planning horizons and still be ecologically meaningful, we
recommend that adaptive management course corrections occur in 2025, at which time goals will
be re-examined and the next adaptive management planning horizon will be set. The Technical
Committee will oversee monitoring efforts in the intervening periods and recommend changes if
warranted by interim results.
Cedar River Habitat Goals
Short -Term Goal: Total connected floodplain acres between Lake Washington and Landsburg
Diversion Dam will be 1,170 acres by 2025.
Long -Term Goal: Total connected floodplain acres on the Cedar River between Lake Washington and
Landsburg Diversion Dam will be at least 1,386 acres by 2055.
Indicator: total connected floodplain areas.
Reconnecting floodplains along the Cedar River is a key action and one of the highest priorities for
Chinook salmon recovery in WRIA 8. Monitoring indicates that while juvenile Chinook salmon fry are
density -independent (more redds = more fry), parr survival appears to be density -dependent (more
redds ; more parr).
For this goal, the moderate channel migration zone (CMZ) is used to define the floodplain area and
assess floodplain connectivity. The moderate CMZ was chosen because this area could be actively
engaged by the river by lateral migration, and therefore would directly (and positively) affect river
processes. The WRIA 8 TC chose the CMZ rather than the Federal Emergency Management Agency
(FEMA)100-year floodplain because of this direct relationship to the restoration of habitat -forming
processes.
There are 1,419 total floodplain acres on the Cedar River below the Landsburg Diversion Dam,
using the moderate CMZ as the indicator of floodplain area. As of 2015 (WRIA 8 TC, unpublished
data) approximately 380 acres, or 26 percent of the CMZ2 is behind levees, revetments, or other
hard structures (i.e., disconnected). The pace of reconnection in the first 10 years of the 2005 Plan
implementation (which averaged 6.44 acres per year, for a total of 64.4 acres) is insufficient to support
long-term Chinook salmon viability in the watershed. The WRIA 8 TC determined that doubling that
pace is appropriate as well as feasible. This would add 130 acres by 2025 and decrease the amount of
disconnected floodplain from 26 percent to 17.5 percent of the total area. The 2055 goal would be to
decrease the amount of disconnected floodplain further, to 9 percent of the CMZ or less.
Short -Term Goal: Average wood volume will quadruple by 2025 relative to 2015 basin conditions (river
mile [RM] 4 to Landsburg Diversion Dam) by 2025 (i.e., from 10.4 m3/100 m to 42 m3/100 m).
Long -Term Goal: Average wood volume between RM 4 and Landsburg Diversion Dam will be 93
m3/100 m by 2055 (the median wood volume for streams over 30 meters bankfull width) (Fox and
Bolton, 2007).
Indicator: Average wood volume (m3/100 m)
2 All mentions of CMZ in this document refers to the moderate CMZ.
Using a recent remote -sensing product (NOAA 2015), the WRIA 8 TC estimates 5.2 m2/100 m wood
area in the Cedar River between RM 4 and Landsburg Diversion Dam. If the typical wood logjam is
assumed to be 2 meters tall, the estimated wood volume would total 10.4 m3/100 m. This value is
substantially below regional standards (Fox and Bolton, 2007) and needs to be enhanced. Even four o
times the current value (42 m3/100 m) does not achieve the 25th percentile of the regional standard —
and is still poor by that standard, but it is an ambitious goal to achieve by 2025. The 2055 goal would
w
be to reach the median value for streams over 30 meters bankfull width (i.e., 93 m3/100 m).

TC considers the Sammamish River to reflect poor condition for wood volume.
M
A recent report on cooling options for the Sammamish River indicates that there are limited
$
opportunities for creating thermal refugia along the river (R2 Resource Consultants 2010). As indicated

Wood volume is currently far below minimum standards for functional stream systems in every WRIA
8 stream (King County 2015). The TC acknowledges that the best realistic goal for streams inside
the UGA would be to attain the 25th percentile of Fox and Bolton (2007) standards. Some WRIA 8
streams outside the UGA can realistically attain the 50th percentile, while a few may approach the 75th
percentile in some reaches. The TC will encourage project proponents to install loads approaching the
75th percentile in appropriate projects.
—6 This goal requires fieldwork to quantify current wood loads in these streams. The WRIA 8 TC will

J
Natural riparian shoreline refers to native trees and tall shrubs. This may also include projects from
the City of Seattle's guide to environmentally sound alternatives to shoreline bulkheads (a.k.a. Green
Shorelines projects — City of Seattle, nd). It may be possible to quantify current conditions via remote
sensing. Note: the minimum assessment unit size is 25 feet by 25 feet.
Marine Nearshore Habitat Goals
Short -Term Goal: Pocket estuaries along WRIA 8 shoreline will supportjuvenile Chinook salmon for
rearing and migration. Reconnect two stream mouth pocket estuaries by 2025.
Indicator: Number of tributary stream mouths connected to nearshore.
A stream mouth assessment that quantifies the number of stream mouths connected or disconnected
is still needed. A "connected" stream is defined as connected to the nearshore through natural
channel profile and delta formation processes.

Protect and Restore Floodplain Connectivity
Floodplains provide crucial habitat forjuvenile salmon to rear and find refuge from floods and
o predators. Connected floodplains and associated riparian and instream habitat provide sources of
large wood that slow fast-moving water and create channel complexity through braiding and formation
of side channels, backwater channels, and off -channel wetlands. In addition, floodplain reconnection
aimproves the connection between surface water and groundwater, and this connectivity provides a
n source of cooler water and reduces the impacts of increased water temperatures from other factors.
Z) This strategy will help decrease the negative impacts of nearby land use, levees and revetments,
a problematic peak and low flows, and increased sediment and pollutant loads. It will also promote
resilience to effects of climate change. Monitoring data suggest that —for the Cedar River especially —
rearing capacity is a greater limitation than spawning capacity, and restoring floodplain connectivity
is the best way to address this limitation. Reconnecting floodplains often provides additional benefits,
such as reducing flood risk, improving recreational opportunities, and improving water quality.
Focus areas:
• Highest priority — Cedar River from Landsburg Diversion Dam to Lake Washington
• Sammamish River — feasibility to implement may be limited
• Issaquah Creek — throughout sub -basin, including Carey and Holder Creeks, with restoration
especially important along Lower Issaquah Reaches 1 — 7 and Lower North Fork and East Fork
• Bear Creek — throughout sub -basin, with restoration especially important along Lower Bear Reaches
1 — 7 and Cottage Lake Creek Reaches 1 and 2
• North, Little Bear, Evans, and Kelsey creeks, where opportunities exist
Life stases:
Juvenile rearing, especially parr migrant stage in the Cedar River.
Relevant actions:
Site -specific actions include installing levee setbacks, reducing or removing bank armoring to allow
channel migration and interaction between the main channel and floodplain, and acquiring lands to
protect areas featuring natural river processes or to enable future floodplain restoration work.
Outreach/education actions include building support for funding and implementation of restoration
projects, with fact sheets, media coverage, and tours.
Land use actions include coordinating with and leveraging floodplain management to develop policies
and identify areas where habitat and flood control benefits can be achieved jointly, and implementing
and enforcing local government critical area ordinances and shoreline master programs (SMPs),
especially buffer and setback requirements on rivers, streams, and lakeshore areas.
Habitat goals:
• Total connected floodplain acres on the Cedar River between Lake Washington and Landsburg
Diversion Dam will be 1,170 acres by 2025.
o Long-term goal: Total connected floodplain acres on the Cedar River between Lake Washington
and Landsburg Diversion Dam will be at least 1,386 acres by 2055.
• Current average wood volume in the Cedar River will quadruple between RM 4 and Landsburg
Diversion Dam by 2025.
o Long-term goal: Average wood volume in the Cedar River between RM 4 and Landsburg
Diversion Dam will be 93 m3/100 m by 2055 (the median standard wood volume for streams over
30 meters bankfull width).
Implementation goals: Reconnect 130 additional acres by 2025; increase wood volume from 10.4
m3/100 m to 42 m3/100 m by 2025.
Protect and Restore Functional Riparian Vegetation
Protecting and restoring riparian trees is important throughout the watershed and offers direct and
indirect benefits to Chinook salmon via food web inputs, water quality protection (including reducing
thermal, pollutant, and fine sediment inputs), and as a source of large wood for recruitment. This
0
strategy mitigates some of the impacts of land conversion and urbanization, shoreline armoring,
—
invasive plant infestations, polluted stormwater runoff and increased water temperature from climate
change. In Tier 2 areas, this strategy is particularly important to prevent loss of spawning or rearing
p
habitat, ultimately protecting the spatial diversity of Chinook salmon in the watershed. By trapping

sediment and filtering pollutants, functional riparian buffers also reduce the impacts of nonpoint
a
pollution.

Protect and Restore Channel Complexity
Complex stream channels provide a range of habitats necessary for Chinook salmon spawning,
rearing, and survival. They provide pools and eddies where salmon can rest, feed, and find refuge from
predators and floods. Adding large wood can improve natural processes for maintaining or creating
pools and riffles and sorting sediment and gravels, all of which create the complex habitat that salmon
require. Increased wood loading will improve habitat complexity in nearly all areas of stream habitat
within WRIA 8. Restoring channel complexity lessens the impacts of shoreline hardening, altered peak
flows due to impervious surfaces, and increased water temperatures.
Focus areas:
Throughout the watershed, including the Cedar River and other Tier 1 streams (Bear/Cottage Lake,
Issaquah); the Sammamish River; and Tier 2 streams, including Little Bear Creek, North Creek, Kelsey
Creek, and Evans Creek.
Life stages:

Restore Shallow -water Rearing and Refuge Habitat
Gently sloping sandy beaches maximize shallow -water habitat for lake -rearing juveniles outmigrating
to Puget Sound, and can help provide refuge from native and non-native predators. Bulkheads or
0
other shoreline hardening and nighttime lighting affect juvenile behavior in ways that may increase N
their susceptibility to predation. The effects of these changes can be mitigated in key areas through
soft shoreline techniques and lighting modifications. Shallow -water rearing and refuge habitats are
particularly critical in Lake Washington south of 190 as lake -rearing juveniles enter from the Cedar p
River to rear in and migrate through the lake, as well as the south end of Lake Sammamish where D
juveniles enter from Issaquah Creek. Improved shorelines throughout the migration corridor would
a
improve refuge from predation and provide terrestrial insects for food. j

Reconnect and Enhance Creek Mouths
The area where a creek enters a river or lake provides habitat forjuvenile rearing and refuge from
predators asjuveniles migrate to marine waters. Daylighting or restoring creeks, reducing their
gradient to make them available to juvenile salmon, and removing armoring near creek mouths should
restore their ecological function and reduce the impact of land cover conversion for residential,
commercial, or industrial use, as well as the effects of predation. All creek mouths are important,
but efforts should prioritize those in the south end of Lake Washington for rearing and migration to
increase survival of Cedar Riverjuveniles. This includes enhancing the associated creek delta habitat.

Protect and Restore Cold -water Sources
and Reduce Thermal Barriers to Migration
Areas of water warmer than about 65 degrees F can delay migration, diminish spawning success,
CN
and contribute to pre -spawn mortality. While other strategies help protect and restore cold water
_
sources (e.g., floodplain reconnection, riparian cover and forest retention throughout the watershed),
u,
this strategy focuses specifically on key areas known to be migratory bottlenecks, or where problems
o
could develop for other life stages through climate change impacts. Because ocean -type Chinook
a
salmon do not live in fresh water during summer, the effects of increased summer temperature are
less pronounced for them than for other resident salmonids. However, high water temperatures
w
may indirectly exacerbate other stresses to Chinook salmon (e.g., disease) as they migrate or rear,
o
ultimately affecting their survival and/or ability to reproduce. This emerging issue will be tracked and
adaptively managed, particularly as it affects key life stages. Cold -water sources will become more
important throughout the watershed for all life stages, notjust migration, as water temperatures

Improve Juvenile and Adult Survival at the Ballard Locks
The primary fish passage barrier in the watershed is the Ballard Locks, which affects salmon survival
and the timing of adult and juvenile passage into and out of the watershed. As a legacy land use
impact that forever changed the hydrology of the watershed, the pressure exerted by the Ballard
Locks can be mitigated but not removed. Measures to improve fish passage conditions and survival
through the Ballard Locks are of paramount importance. This strategy focuses on USACOE funding
and implementing critical facility upgrades to ensure effective fish passage and continued safe facility
operation.
Focus area:
Ballard Locks
Life stapes:
Adult migration, juvenile migration
Relevant actions:
Site -specific actions include improving fish passage facilities in concert with overall structural
improvements. Fish passage improvements include updating or replacing smolt flumes, replacing
large lock filling culvert valves and machinery (i.e., Stoney Gate valves) permanently screening off
the diffuser well to prevent entrainment of salmon in the saltwater drain, ensuring effective passage
at the fish ladder, scraping the filling culverts annually to remove barnacles and prevent harm to fish,
and implementing "reasonable and prudent measures" identified in the Lake Washington Ship Canal
Biological Opinion.
Outreach/education actions include outreach to state legislators, Congress, and federal agencies
through fact sheets, media coverage, and tours, and building support for funding among
decision -makers.
Regulatory actions include supporting National Marine Fisheries Service and USACOE work to update
the Biological Opinion for operation of the Ballard Locks, with salmon passage and survival needs as a
primary consideration, including updated and revised "reasonable and prudent measures" and other
required actions.
Pressure reduction goal:
• By 2025, the USACOE has completed critical fish passage facility improvements at the Ballard Locks
for both adults and juveniles.
Reduce Predation of Juvenile Migrants and Lake -rearing Fry
Predation of juvenile Chinook salmon by native and non-native species is a long -suspected issue
affecting juvenile survival in the freshwater system, especially in Lake Washington, Lake Sammamish,
and the Ship Canal. The magnitude of the problem is not well quantified, and ongoing research
is attempting to clarify the relative impact of predation on freshwater juvenile survival in WRIA 8.
Additionally, emerging research suggests that artificial nighttime lighting may alter juvenile fish
behavior in a way that makes them more susceptible to predators and increases the length of time
predators actively feed. With improved juvenile survival, greater numbers of adults are likely to return,
boosting the odds for recovering a self-sustaining Chinook salmon population.
Focus areas:
• Lake Washington
• Ship Canal (Ballard Locks to Portage Bay)
• Lake Sammamish
Life stages:
Juvenile migration, lake rearing
Relevant actions:
Site -specific actions will be determined once sub -strategies are better defined but could include
predator control (e.g., bounties on native and non-native fish that are determined to cause significant
predation on Chinook salmon juveniles, or removal of predators from focal areas such as parts of the
Ship Canal), artificial light modifications, and improvement of coho salmon habitat to diminish cutthroat
trout success. Actions that reduce water temperatures and remove or mitigate overwater structures
(represented in other strategies) may also reduce pedation.
Outreach or education actions will be determined once current research clarifies predation impacts
and management actions that address them.
Remove or Reduce Impact of Overwater Structures
Removing or reducing the impact of overwater structures works to alleviate the pressure of residential
oand commercial land use along the lakeshores and migration corridors. This strategy reduces the
effects of docks, piers, pilings, and other overwater structures that make juveniles more susceptible to
predation since docks can provide cover for predators and/orjuveniles will avoid overwater structures
aand move to deeper water where they are more susceptible to predators. The primary purpose of this
strategy is to improve juvenile survival during lake rearing and outmigration.

Remove Fish Passage Barriers
Ensuring that Chinook salmon can access a range of habitat types is important for all life stages, but
fish passage is not a primary limiting factor in WRIA 8 for many life stages of Chinook, especially since
the two largest passage barriers that existed at the time of the ESA listing —the Landsburg Diversion
0
N
Dam and the Issaquah Hatchery Intake Dam —have been addressed. Providing juvenile Chinook
—
salmon with access to more area for rearing, especially in small channels where many fish passage
barriers still exist, is important. Also, ensuring juvenile access to available cooler water habitat can
o
mitigate the effects of increased water temperatures. Removing barriers to fish passage is also an
important strategy to ensure that Tier 2 areas are not further degraded and that spatial diversity of the
Q
populations is not hampered by cutting off habitat through current or future land use. Although most
Lit
barriers in the watershed affecting Chinook salmon are thought to be partial rather than full, these
barriers could degrade and create larger impediments to fish passage. As development continues
and new roads are built, creek crossings should be minimized to prevent future barriers, and new
crossings should use bridges or culverts designed to accommodate fish passage.

Protect and Restore Forest Cover and Headwater Areas
n
Retaining forest cover and functional upland habitat in areas throughout the watershed is important
o for water quantity and quality, particularly to address changes in winter peak flows, summer low flows,
and water temperatures as climate change progresses. This strategy reduces the impacts of land
conversion, pollutant- and sediment -filled runoff, and changes in water flow and temperature. Since
aimplementation of the 2005 Plan, many of the opportunities to purchase or protect headwater areas
have been acted on or otherwise addressed. Remaining opportunities are limited but exist along the
middle and upper reaches of Bear/Cottage Lake, Issaquah, Little Bear, and North creeks. Incentivizing
w and regulating retention of forest cover and reforestation on private lands, as well as reducing
r impervious cover through low -impact development (LID) practices, are likely to indirectly benefit all life
o stages of WRIA 8 Chinook salmon populations.
Focus areas:

Cold Creek
• Issaquah Creek — especially along Carey and Holder creeks, middle Issaquah Creek Reaches 11 and
12, Fifteenmile Creek, and East Fork Issaquah Creek
• Upper reaches and headwaters areas of all Tier 2 sub -basins
Life stage:
All life stages benefit but this is not a key strategy for any specific life stage.
Relevant actions:
Site -specific actions include fee -simple land acquisition, transfer of development rights, and
conservation easements to protect intact forestlands, especially in areas where contiguous forest
cover can be protected. Restoration is focused on reforestation of lands outside the riparian corridor.
Outreach/education actions include streamside landowner outreach, and awareness and incentive
programs focused on retaining forest cover, reforestation, and reducing impervious cover through LID
practices.
Land use actions include implementing and enforcing local government critical area ordinances and
SMPs, especially buffer and setback requirements on rivers and streams, and offering incentives to
retain forest cover and plant forested areas.
Provide Adequate Streamflow
Adequate streamflow is important to provide habitat during critical rearing and migration stages.
This strategy, intended to address the impacts of both high and low flows, would reduce the impacts
of land conversion, water withdrawals, increasing water temperatures, scouring events, and fish
passage barriers. Reducing illegal withdrawals and protecting or enhancing flows are important actions
throughout WRIA 8, especially in the Sammamish River basin and its tributaries, and may become more
important in the future as climate changes.

• Bear Creek — especially upper Bear Creek Reaches 7 through 16, and Cottage Lake Creek and Cold
Creek
• Issaquah Creek — especially North Fork Issaquah Creek Reach 1
• Sammamish River
Life stage.•
All life stages benefit but this is not a key strategy for any specific life stage.
Relevant actions:
Actions to protect instream flows include reconnecting floodplains, preventing illegal withdrawals, and
protecting aquifers and critical aquifer recharge areas (CARA). Green stormwater infrastructure (GSI)
projects that improve groundwater recharge could help sustain streamflow.
Outreach/education actions include promoting water conservation and LID to the general public, and
incentivizing retention of forest cover and reforestation to private landowners and the development
community.
Land use actions include implementing and enforcing local government development regulations

Restore Sediment Processes Necessary for Key Life Stages
This strategy addresses two issues — excessive fine-grained sediments and insufficient spawning
gravel. An excess of fine sediment is of concern during incubation, when redds/eggs can be
suffocated by fine particles. Beneficial gravels for spawning can be lacking where natural sediment
recruitment processes are interrupted. This strategy reduces the impacts of land conversion, shoreline
hardening, and impervious surface runoff.
Focus areas:
• All Tier 2 sub -basins
• Issaquah Creek
• Cedar River
Life stages:

Relevant actions:
Site -specific actions include protecting confluence areas that provide high quality spawning gravel,
removing shoreline armoring, placing instream wood, and planting riparian areas.
Outreach/education actions to reduce the amount of fine sediments include promoting water quality
BMPs and green infrastructure programs to landowners and developers in priority areas, incentivizing
retention of forest cover and reforestation of private lands, as well as reducing impervious cover
through LID practices.

Restore Natural Marine Shorelines
Preventing and removing bulkheads and armoring along the marine shoreline will allow for a more
natural shoreline with increased overhanging vegetation, connected drift cells and pocket estuaries,
o
and increased extent of eelgrass beds and forage fish spawning habitat. These features will improve
the marine food web function and increase success of juvenile Chinook salmon rearing and migrating.
The BNSF railway runs along most of the WRIA 8 marine shoreline, severely limiting restoration
a
opportunities. However, any shoreline enhancement or restoration will offer regional salmon recovery
o
benefits, as Chinook salmon from other watersheds also rear in or migrate through the WRIA 8
nearshore. Opportunities exist to enhance the habitat in front of the BNSF railway through beach
a
nourishment, as well as behind or above BNSF through riparian restoration. Identifying and restoring
shoreline sediment processes is also important to support habitat for primary Chinook prey species,
such as sand lance and smelt.
—
Focus Area:
• Entire WRIA 8 marine nearshore (Snohomish County and King County have identified potential beach
nourishment locations that could be used to support prioritization)
Life stages:
Juvenile migration and marine rearing
Relevant actions:
Site -specific actions may include removing bulkheads and shoreline armoring to enable habitat -
forming processes, and completing beach nourishment projects where beach substrates need
supplementation or where restoring habitat -forming processes is not feasible. The replacement of
culverts under the railroad with bridges or trestles can also facilitate greater sediment transport to
the nearshore, enabling beach formations to establish and persist. Establishment of pocket beaches
and coves can also provide important rearing and refuge opportunities, especially close to the Ballard
Locks.
Outreach/education actions include outreach to property owners, including jurisdictions and BNSF,
to promote green and shoreline softening alternatives to bulkheads and other shoreline armoring;
project -specific fact sheets; media coverage; and tours.

Reconnect Backshore Areas and Pocket Estuaries
Many backshore areas and pocket estuaries (generally defined here as small creek mouths) have been
disconnected from Puget Sound, resulting in a lack of tidal inundation and reducing or preventing
access by migrating adult and juvenile salmon. Along the nearshore, creek mouths provide important
rearing habitat, and recent research suggests these areas are important to the overall life history of
Puget Sound salmon. Much of the WRIA 8 shoreline is disconnected from the Sound by armoring from
the railroad prism, but juvenile salmon need viable rearing and refuge locations along the shoreline
wherever possible. This strategy will mitigate the effects of the railroad, perched culverts, and
shoreline hardening in commercial and residential areas.
Focus area:
• Entire WRIA 8 marine nearshore, with particular emphasis on those small streams that have the
greatest potential to offer non -natal rearing habitat
Life stages:
Juvenile migration and marine rearing (for all populations in the evolutionarily significant unit south of
WRIA 8, and potentially the WRIA 7 population in the northernmost portions of the watershed)
Relevant actions:
Site -specific actions include replacing culverts or other obstructions in a manner that allows natural
processes and tidal interaction with backshore habitat, daylighting streams along the nearshore, and
reconnecting tidal wetlands and pocket estuaries that have been disconnected (in many cases by the
railroad).
Outreach/education actions include outreach to property owners, including jurisdictions and BNSF;
project -specific fact sheets; media coverage; and tours.
Land use actions include implementing and enforcing local government SMP regulations, and working
with regional partners, state and federal agencies, local governments, and BNSF to reconnect pocket
estuaries where coastal streams flow into Puget Sound through culverts under the railroad tracks.
Habitat goal:
• Pocket estuaries along WRIA 8 shoreline support juvenile Chinook salmon for rearing and migration.
Implementation goal:
Reconnect two pocket estuaries (tributary stream mouths) to the nearshore by 2025.
Protect and Restore Marine Water and Sediment Quality
Improving marine water and sediment quality where possible and capping contaminated sediment
in the nearshore, especially near commercial and industrial areas, may improve early marine survival
directly or indirectly. Additional research is needed to better understand how impaired marine water
and sediment affect Chinook salmon early marine survival and the food web. WRIA 8 will track and
adaptively manage this emerging issue. The strategy will mitigate the legacy and current impacts of
land conversion and of point and nonpoint source pollution.
Focus areas:
Portions of the WRIA 8 marine nearshore affected by commercial or industrial water or sediment
quality issues
Life stages:

Relevant actions:
Site -specific actions will be determined through adaptive management. Most water quality issues will
be more appropriately addressed through regulatory site cleanup and remediation, although creosote -
treated in -water structures may fall outside of the regulatory landscape.
Improve Water Quality
"Water quality" is multi -faceted and intersects with salmon recovery in many ways. The purpose of this
n 0 strategy is to support water quality improvements beyond water quality permit requirements through
encouraging individuals and jurisdictions to participate in voluntary and incentive -based programs.
Improvements should target reductions in polluted runoff from impervious surfaces, nonpoint source
apollution, fine sediment inputs, and altered flows. This strategy is primarily implemented through
o education and outreach programs. Several water quality elements are also addressed by other
Z) strategies in this section (local and regional planning, regulations, and permitting; protect and restore
wcold water sources and reduce thermal barriers to migration). New regional research is underway to
identify possible impacts of polluted stormwater runoff on Chinook salmon, and any findings will be
adaptively managed at the local level and in implementation of the 2017 Plan.

Local jurisdictions, state agencies, and federal agencies should consult the WRIA 8 plan for the
best available science on incorporating Chinook salmon requirements into required planning for
shorelines, land use, water quality, and project permitting. The 2005 Plan and this update are built on
the assumption that regulations are protective and supportive of sustaining salmon in the watershed;
the other strategies articulated in the plan provide the additional ecological lift necessary for recovery.
While WRIA 8 staff will not track these actions specifically, or likely fund capital projects through the
process, this strategy is foundational to the others.
Focus areas:
• Throughout watershed
Life stages:
All
Relevant actions:
Outreach/education actions will promote the WRIA 8 plan as best available science for regulatory
updates and permitting. These actions will also promote model programs where jurisdictions
successfully implement their regulatory programs in a manner that aligns with Chinook salmon
recovery strategies.
Land use actions for integrating salmon recovery priorities include developing and updating land use
regulations to include provisions that seek to protect salmon habitat needs. These salmon habitat
needs include large shoreline and riparian buffers and setbacks, strong stormwater management
standards, appropriately restrictive development codes and standards, and effective protections for
critical and environmentally sensitive areas.
Goal:
• Land use regulations limit additional habitat degradation and support all habitat restoration goals
through implementation of recovery strategies and actions.

Continue Existing and Conduct New Research, Monitoring,
and Adaptive Management on Key Issues
Specific research and monitoring are necessary to ensure that the latest science informs
implementation of recovery strategies and actions. The MAP (Appendix A) details the indicators
that should be tracked to support a complete adaptive management cycle. This strategy highlights
research and monitoring needed to further develop or refine strategies or address data gaps on
specific issues critical for recovery. These include emerging issues such as impacts on salmon survival
from predation, artificial light, and climate change. WRIA 8 relies on regional research for issues related
to stormwater impacts and early marine survival, such as the Salish Sea Marine Survival Project.
Focus areas:
Throughout watershed, as determined by priority issues or data needs
Life stages:
All, primarily salmon population recovery bottlenecks (e.g., stream and lake rearing and migration)
Specific research underway:
Fish use of habitat restoration projects (i.e., project effectiveness), juvenile passage and survival at
the Ballard Locks, predation in the Ship Canal and Lake Washington, and effects of artificial light on
juvenile salmon behavior and survival
Goal:
Gaps are identified where future research is needed; feasibility studies are implemented to identify
possible options for reducing temperatures in the Ship Canal and Sammamish River.
Increase Awareness of and Support for Salmon Recovery
While most strategies include specific outreach/education actions to support their implementation
this strategy is entirely focused on the importance of raising awareness of and broadening support
o
for salmon recovery in general. The intent of this strategy is to ensure watershed -wide awareness of
ry
salmon, agreement on the ecological, cultural, recreational and economic importance of salmon in
the watershed, and an understanding of the individual actions that can support salmon recovery. With
a growing human population in the watershed and many new residents who may be unfamiliar with
o
Chinook salmon, this strategy is critical to meeting specific habitat and Chinook salmon population
goals articulated in this plan.

Relevant actions:
Outreach/education actions include continuing to coordinate the Salmon SEEson program and other
general salmon recovery awareness -building to increase public knowledge of, interest in, and support
for salmon recovery, such as Cedar River Salmon Journey, Beach Naturalists. Additional actions
include behavior change programs, and outreach and education for key audiences, including elected
officials, schoolchildren, development and landscaping industries, and shoreline and streamside
property owners.
Goal:
• Education and outreach actions support all habitat restoration goals.

Proposing Projects and Programmatic Actions for Implementation -
o
WRIA 8 Four -Year Work Plan
ry
As required by the Puget Sound Partnership, as the regional salmon recovery organization, WRIA
u,
8 maintains a "Four -Year Work Plan" that identifies the highest priority, most ready -to -go projects,
and the most important monitoring and outreach and education actions for implementation in the
a
watershed (note: the Four -Year Work Plan is an iterative planning tool and not included in the 2017
Qo
Plan; the most current Four -Year Work Plan is available on the WRIA 8 website at http://www.goviink.
w
org/watersheds/8/planning/default.aspx). The Four -Year Work Plan is essentially a subset of the larger
}o
WRIA 8 project list and recommended land use and education and outreach actions, and is intended
to provide the near -term roadmap for recovery. Representation on the Four -Year Work Plan is also a
prerequisite for WRIA 8 grant funding consideration.
Each year, WRIA 8 issues an open call for sponsors interested in elevating projects to the Four -Year
Work Plan. A sponsor can directly pull an existing acquisition or restoration project from the WRIA 8
project list to advance for implementation, and in such cases, they can propose that the project be
considered by the WRIA 8 TC for inclusion on the Four -Year Work Plan. In addition to projects, the
WRIA 8 TC also considers and recommends which monitoring priorities to include on the Four -Year
Work Plan, and the IC considers and recommends which land use -related actions and education and
outreach actions to include. Committee recommendations are reviewed and approved by the WRIA 8
Salmon Recovery Council.
The annual open call also offers an opportunity for sponsors to propose new projects that are not
directly referenced in the WRIA 8 Plan (i.e., proposing a project that is not specifically identified in the
Plan but meets the Plan's objectives for salmon recovery). Following the 2017 Plan, the intent is that
sponsors proposing new projects will connect their proposal to the relevant recovery strategy outlined
in this update. In so doing, the sponsor will demonstrate the connection of the proposed activity to
priority WRIA 8 recovery objectives and illustrate the fundamental merit of the project as one with
salmon recovery as a primary objective. Specific technical details would be assessed at a later time,
but at a minimum, new project proposals put forward to WRIA 8 must establish a connection to one or
more of the updated recovery strategies to be included in the 2017 Plan and Four -Year Work Plan.
To summarize, project sponsors have an annual opportunity to submit projects and programs to the
WRIA 8 Four -Year Work Plan, which may involve:
Proposing a project or activity from the current WRIA 8 habitat protection and restoration project list
or from the current land use or education and outreach activity lists.
Proposing a new project or activity that is not identified in the WRIA 8 Plan but is consistent with one
or more of the WRIA 8 Chinook recovery strategies. The sponsor must be able to demonstrate a
