Lake Sammamish Watershed, Washington
This is a view during the fall 2015 kokanee spawning run from Ebright Creek, a tributary of Lake Sammamish whose headwaters include Sammamish City Hall grounds. In November and December, we brought you a live view of returning kokanee with an underwater camera. Now that spawning season is over, we thought you might enjoy some recorded highlights of kokanee swimming past our camera. They certainly weren’t camera-shy!
The returning kokanee in this view were in some of the healthiest spawning habitat that remains in the Lake Sammamish watershed. All of these fish spent their whole lives in the Lake Sammamish watershed, and most spent three summers in Lake Sammamish growing from inch-long fry to 12- 16-inch-long spawners. Ebright Creek is one of only three creeks that today hold spawning kokanee in significant numbers, and it often holds the highest number of returning kokanee in any year. The fish with more red and humped backs are males; those that are more striped gray and red are female fish.
Kokanee salmon are historically native to the Lake Sammamish and Lake Washington watershed, and the Lake Sammamish kokanee population is one of only two populations native to the Puget Sound basin. The other is 90 miles away in Whatcom County.
Adult kokanee have silvery sides and a blue back while living in Lake Sammamish, and grow to be about 12-16 inches long.
These salmon spend their entire lives in Lake Sammamish and its streams - they do not go to the ocean like most other salmon. The health of this kokanee population has declined dramatically in recent decades, so these fish are in danger of extinction if no action is taken in the watershed to help them recover. Some of these fish will be taken to the Issaquah Salmon Hatchery as part of a program initiated in 2007 by the Lake Sammamish Kokanee Work Group. This program produces kokanee that are released in their home streams in the spring, to help prevent the extinction of these native kokanee and improve the health of the population so it eventually supports a renewed kokanee fishery on the lake. This program has successfully raised and released young kokanee for six consecutive years and is anticipated to continue into the early 2020s.
