Trout Lake

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.

Two-pole fishing is allowed

Shoreline access: Good - Undeveloped shoreline, moderate hike required.

Fishing prospects calendar

Rainbow trout

Fishing success for Rainbow Trout is generally best in the spring when thousands of fish are stocked statewide, but they can be caught year-round in most waters with a little patience and persistence. Success remains high into June and gradually declines as water temperatures increase and fish move offshore to stay cool. Fish that escaped the spring harvest return to the nearshore areas in the fall as waters cool off. Some waters may also be stocked again in the fall further boosting catch rates.
