This is the "wilderness" Trout Lake in King County. It is located in the West Fork Foss River drainage, about seven miles south of Skykomish. The lake at slightly over 2000 feet elevation, and may not be easily accessible during colder months. This lake is heavily fished, so the naturally reproducing Rainbow Trout do not reach large size. Expect fair fishing for six to ten inch trout. The best time to fish is in the early morning and evening, due to high water clarity. A very popular hiking destination for generations, the lake was raised several feet by a major rockslide across its outlet in the early 1990s.
