Dramatic Dropoff In Lake Sammamish Kokanee Population Spurs Action


A work group created by King County is taking emergency and long-term action to counter an alarming downward trend of Lake Sammamish kokanee, a native salmon population that appears closer than ever to extinction.

County and state biologists counted fewer than 20 kokanee in the most recent return, five years after more than 18,000 spawners returned from Lake Sammamish.

“The native kokanee salmon – important to our history, our culture, our environment – are facing new challenges that potentially threaten their very existence,” said King County Executive Dow Constantine. “Together with our partners, we will take new, immediate actions to protect the iconic species and continue our long-term work to create healthier salmon habitats throughout our region.”


Biologists are investigating a number of possible factors that led to the most recent dramatic decline, including the increasing frequency and magnitude of harmful high temperatures and low-dissolved oxygen conditions during summers in Lake Sammamish. They are also beginning to study the compounding effects of parasites, bacteria, and related diseases during these events.

The Lake Sammamish Kokanee Salmon Work Group – which King County created in 2007 to help guide strategies to protect the unique species – recommended a series of immediate and long-term actions:

  • Use specially designed traps to capture returning spawners for the hatchery program
  • Use the latest technology to protect the unique genetic stock of Lake Sammamish kokanee
  • Release young salmon into Lake Sammamish in the fall of 2019, after the lake’s temperature cools and oxygen levels rise
  • Reintroduce kokanee salmon to additional creeks in the watershed, reducing the risk that a flood or drought in a single creek will wipe out the entire run
  • Lead technical work to understand and guide strategic actions to address the underlying factors that are threatening the kokanee population

For the past decade, the Kokanee Work Group – an alliance of tribal and local governments, state and federal agencies, landowners, and residents of the watershed – has worked together with the shared goal of a healthy, stable kokanee population.

The Work Group continues to make progress, with more than 18,000 spawners returning to Lake Sammamish during the 2012-13 run. But scientists are concerned that the new challenges have the potential to wipe out the remaining kokanee population unless immediate action is taken.

Working together to restore healthy salmon habitats throughout King County

King County and other land managers are continuing their habitat-restoration work that will improve the health of the kokanee salmon population. The ongoing work includes:

  • Removing barriers to healthy habitats, such as replacing fish-blocking culverts along the East Sammamish Trail and Parkway so salmon can move up and down streams
  • Planting thousands of trees and shrubs that provide shade and cover for salmon
  • Increasing public awareness and education to reduce stormwater pollution
  • Partnering with the Issaquah Hatchery to help secure remaining kokanee population

In addition to being culturally significant, the native kokanee are important to the bio-diversity of our region. They have a unique genetic signature, having adapted to the unique Lake Sammamish ecosystem, making them impossible to replace. Genetic diversity makes the natural environment healthier and more resilient, which is particularly important in the face of climate change.


The kokanee run that occurs in November and December – known as “the late run” – is the only remaining native run. The two other native runs that historically occurred between late August and early November no longer occur because those kokanee have been extinct since the 2000s.

The Lake Sammamish Kokanee Work Group active membership includes the Snoqualmie Tribe, each of the five local jurisdictions in the Lake Sammamish watershed, the U.S. Fish and Wildlife Service, the Washington Department of Fish and Wildlife, Washington State Parks, Trout Unlimited, Mid-Sound Fisheries Enhancement Group, Mountains to Sound Greenway Trust, Friends of Issaquah Salmon Hatchery, Save Lake Sammamish, Friends of Pine Lake, Friends of Lake Sammamish State Park, and residents who live in the watershed.

Elk, Habitat, Hunters In 16 Washington Counties Benefit From $233K In RMEF Grants


The Rocky Mountain Elk Foundation awarded $233,373 in grant funding for nearly two dozen conservation projects in Washington that enhance wildlife habitat, assist research and promote hunting heritage.


The grants benefit 4,966 acres across Asotin, Clallam, Chelan, Columbia, Cowlitz, Douglas, Ferry, Garfield, Grant, King, Pierce, Okanogan, Pend Oreille, Skamania, Snohomish and Yakima Counties. There are also two projects of statewide benefit.

“Forest management techniques like thinning, prescribed burning and noxious weed treatments improve habitat in Washington for elk and many other species,” said Blake Henning, RMEF chief conservation officer. “This grant funding will help with those efforts and supply research dollars to benefit elk management.”

Since 1985, RMEF and its partners completed 621 conservation and hunting heritage outreach projects in Washington with a combined value of more than $121.5 million. These projects conserved and enhanced 471,547 acres of habitat and opened or secured public access to 125,245 acres.

Here is a sampling of the 2017 projects, listed by county:

Asotin County—Apply noxious weed treatment across 700 acres on the W. T. Wooten and Chief Joseph Wildlife Areas within the Blue Mountains Wildlife Area Complex to keep weeds in check on year-long elk range (also benefits Garfield and Columbia Counties).

Clallam County—Thin 203 acres of elk summer range in the Upper Sitkum Watershed on the Olympic National Forest where overly dense forests led to documented low body condition scores for elk as well as downward trends in pregnancy rates.

King County—Provide funding to acquire one new GPS collar and refurbish four others for a study to determine if elk are using new habitat areas created by the Snoqualmie Valley Elk Management Group as well as determine a better herd population estimate and seed 50 acres of a newly cleared area in the foothills of the Cascade Mountains.

Yakima County—Apply prescribed fire to 300 acres on the Oak Creek Wildlife Area as part of a larger, wide-scale effort to benefit wildlife by rejuvenating native grasses, forbs and shrubs as well as mitigating wildfire hazards.

Washington project partners include the Colville, Gifford Pinchot and Olympic National Forests, Washington Department of Fish and Wildlife, and private landowners as well as sportsmen, government, civic and other organizations.
