Martha Alderwood Manor

2023 Trout Derby lake

Starting soon! For more information about how the trout derby works, important dates, and prizes, visit the 2023 Trout Derby page.

Martha is located In Lynnwood, two miles northeast of Alderwood Manor. Stocked Rainbow Trout are the main draw, but resident Largemouth Bass, Yellow Perch, and Brown Bullhead catfish are also present.

This lake is one of only twelve waters in Snohomish 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 an ideal time as fish that have been growing all summer become more active around the lake with cooler temperatures.

The WDFW access on the southeast corner has a boat ramp, parking and toilet. Martha Lake Park (Snohomish County Parks) also offers parking and toilets, plus play and picnic areas and two large fishing piers. Disabled accessibility at county park.

Two-pole fishing is allowed

Shoreline access: Good - Shoreline access at WDFW boat ramp and fishing pier at public park

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.

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.

Yellow perch

Yellow Perch can be caught year-round. Fishing is best in the summer after they finish spawning in April-May. Fish can be readily angled through the summer from both the shore and boat. Catch begins to decline in the fall as water temperatures cool and fish move offshore forcing anglers to pursue them in boats. Successful fishing for Yellow Perch in the winter involves either targeting schools in deep water from boats or through the ice.

Brown bullhead

Fishing improves throughout the spring, peaking before the spawning period in May and June. Fishing may pick up in early Fall, followed by a decrease in action as waters cool. Winter is a difficult time to target this species.
