Lake Margaret

Fishing opportunities include stocked Rainbow Trout and Coastal Cutthroat Trout, and resident Largemouth Bass.

This lake is one of only ten waters in King County managed with a seasonal fishing closure. Spring catch rates for trout are highest early in the season and decline as fish are harvested and as warmer water temperatures force trout to seek areas of colder refuge. Fall is often overlooked by anglers, but can be one of the best times of the year to fish as fish that have been growing all summer become more active around the lake with cooler temperatures.

An undeveloped boat ramp, parking and toilets are available at a WDFW access located at the southwest corner of the lake.

Two-pole fishing is allowed

Shoreline access: Good - WDFW access only

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.

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.
