Kokanee

Oncorhynchus nerka

 
Kokanee are the land-locked form of sockeye salmon. Because they never migrate out to the ocean to feed, kokanee are often much smaller than sockeye. However, other than their size, kokanee have the same identification characteristics as sockeye. Since most kokanee live in a lake for most of their lives, you can usually see them spawning near the edge of a lake or in a small tributary that feeds into a lake. We have kokanee populations in Lake Washington, Lake Sammamish, Issaquah Creek, and many of the other small creeks that feed into these water bodies. If you see a fish, here's some tips to use to determine whether or not it's a kokanee...
