Munn Lake

Munn Lake is open year round. Anglers are limited to selective gear rules and catch and release for all species. The lake offers excellent fishing for rainbow trout 10-20" and the occasional Brown Trout. The lake also supports naturally reproducing Largemouth Bass, Yellow Perch, Bluegill Sunfish, and Black Crappie.  The use of bait and internal combustion motors is prohibited on Munn Lake. 

 Proven methods for targeting Rainbow Trout include fishing multiple chironomid imitations suspended from a float or trolling artifical flies/spinners.  Brown Trout can be found on the margins of the lake in shaded areas and have been caught casting and retrieving artificial minnow imitations and/or spinners.  Shore fishing access is limited to the area around the boat launch.

There is a WDFW access with boat launch and one toilet.

Two-pole fishing is NOT allowed

Special fishing restrictions:

Shoreline access: Good - Access at public boat launch.

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.

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.

Black crappie

Fishing improves throughout the Spring, peaking during the spawn. Summer is a slight lull, while Fall sees an improvement as waters cool, vegetation dies back, and prey becomes more available. During winter, the bite is slower, but anglers can have great success fishing through the ice when conditions are safe.
