Wagner Lake

A couple miles northeast of Monroe. Fishing opportunities include stocked Rainbow Trout and resident Largemouth Bass.

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 southwest shore has a narrow ramp.

Two-pole fishing is allowed

Shoreline access: Good - Access at WDFW boat ramp.

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.
