Lost Lake (Kittitas County)

You'll find this lake about a mile west of Keechelus Lake. With a year-round open season, brook and rainbow trout provide most of the action, but there is also some small kokanee (less than 10 inches). Although brookies average only nine inches, there are some lunkers. The lake is also stocked with jumbo rainbow trout (1-1.5 lbs each) in the spring. No more than two trout over 14 inches may be retained. There is no minimum size or daily limit for brook trout.

Although there is no established boat launch, there is an area at the east end of the lake near the US Forest Service access area where small cartop boats can be launched.

Two-pole fishing is allowed

Shoreline access: Good - Good shoreline access from U.S. Forest Service land.

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.

Kokanee

The Kokanee fishery typically lasts from April-October before the adults leave the lake to spawn in tributaries starting in late-October and early-November. Fishing is best in the spring before they move into deeper water to avoid warming water temperatures, but they can be targeted throughout the summer in deeper offshore areas near the thermocline. There may be a slight uptick in some waters in the fall as adults return to shallower water and move near shore towards spawning tributaries.
