Rates come from standard DNR survey gear (gill nets, trap nets, electrofishing), judged against statewide benchmarks for the same gear, so the same number of fish per net can read differently for two species. Where the standard gear can't count a species reliably, only presence and size are listed. Typical is the middle fish of those measured. Open a row for the full length spread, survey by survey.

How to fish Maple Lake through the year

Walleye

Spring
Walleye are shallow, on and just off the spawning flats and the first green weeds.
Early summer
Walleye are setting up on the outside weed edge, points and shallow structure.
Summer
Walleye are working the weed edge, points and any wind-blown structure. With 96% of this lake 15 ft or shallower, the weed edge is the main event.
Fall
Walleye are packing onto the sharpest breaks and points as the water cools, in big schools with short windows. A 14-ft bowl cools fast, so the fall window comes early here.

Northern pike

Spring
Pike are in the shallow bays and along new weed growth.
Early summer
Pike are on the outside weed edge and points.
Summer
Pike are on the deep weed edge and points near the coolest water they can find. With 96% of this lake 15 ft or shallower, the weed edge is the main event.
Fall
Pike are on the last green weeds and the breaks beside them, feeding heavily as the water drops. A 14-ft bowl cools fast, so the fall window comes early here.

MN DNR · in their words

From the 2024 survey

Maple Lake is a 1,641-acre lake located in northern Polk County, two miles south of Mentor. The maximum depth is 15 feet and the shoreline is considered highly developed with homes and cabins. The lake receives heavy recreational use and angling pressure from the surrounding area. There are two public access points, one on the west end of the lake and another on the east end adjacent to the Rydell National Wildlife Refuge. Maple Lake's fish community provides angling opportunities for Walleye, Northern Pike, Bluegill, Black Crappie, and Largemouth Bass. This survey utilized only gill nets to evaluate the Walleye population in Maple Lake in June 2024.

Anglers will find a high number of Northern Pike in Maple Lake. Most fish will be small, but there is a good opportunity to catch quality pike. The average size of the pike captured was 23 inches, but one 37-inch fish was measured. Additionally, 25% of the pike surveyed were over 26 inches. Walleye numbers were well above average for the lake and the average size was about 13 inches. About 25% of the Walleye captured in 2024 were over 15 inches and 15% were over 20 inches. There should be good numbers of Walleyes in the lake for years to come. Bluegill numbers continue to be good in the lake with plenty of fish over eight inches available for anglers to catch. Black Crappie up to 12 inches long were measured and in moderate numbers. Other fish species observed were Largemouth Bass, Freshwater Drum, Pumpkinseed, Yellow Perch, Brown Bullhead, and Yellow Bullhead.
