This 277-acre lake three miles southeast of Elbe provides excellent trout fishingfor those who enjoy lots of company. The lake sits at 1,770 feet elevation, and on clear days Mt. Rainier provides a scenic backdrop.

The state plants more than 100,000 rainbow trout fry each year. Several hundred larger broodstock are also stocked annually, plus several thousand brown trout.  Largemouth bass are also present.

Most shore fishing is from public fishing docks at the west end of the lake and docks at Mineral Lake Resort. The state boat launch is small, so patience is needed, especially on opening day.

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.

Coastal cutthroat trout (resident)

Fishing is best for Coastal Cutthroat in the spring and fall. There is a summer lull as fish move offshore into deeper waters to escape the summer heat in July and August. Catch is lowest in the late-winter while adults are spawning in tributary streams.
Chart of fishing prospects throughout the calendar year

Largemouth bass

Fishing improves throughout the spring as waters warm and fish move onshore, peaking during the spawn. Summer is a slight lull though dawn/dusk hours can be very good. Catch improves in Fall as waters cool, vegetation begins to die back, and prey becomes more available. Winter is the hardest time because fish are offshore and slow moving.
