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 Deer 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. On a lake that drops to 50 ft, check the deep edge of that structure too.
- Fall
- Walleye are packing onto the sharpest breaks and points as the water cools, in big schools with short windows.
Largemouth bass
- Spring
- Largemouth are moving up into the warming bays and flats, staging around wood, docks and new weeds to spawn.
- Early summer
- Largemouth are on the shallow spawning flats and protected bays, where beds go on firm bottom next to isolated cover.
- Summer
- Largemouth are in and along the weeds: cabbage and milfoil edges, matted cover and shade. On a lake that drops to 50 ft, check the deep edge of that structure too.
- Fall
- Largemouth are chasing bait back onto the flats and into the remaining green weeds, feeding hard and shallow before the freeze.

Longest fish measured by DNR survey crews in each year's nets. Survey gear samples the population, so the lake usually holds larger fish than any survey measured.

MN DNR · in their words
From the 2025 survey
Deer Lake is a 1,748-acre lake located 14 miles east of Effie, MN. The lake has a maximum depth of 50 ft and 1,332 littoral acres. A 10-sunfish bag limit was implemented in March of 2006 to maintain or improve the quality Bluegill population. The sunfish regulation was modified to a 5-sunfish limit in 2023. The 2025 spring targeted survey was the seventh to evaluate the reduced bag limits for sunfish. Trap nets were set and lifted over three days. The water temperature was near 70 degrees F. Bluegill were measured for length, a sample was collected for aging, and sex was also determined.
In the six prior Bluegill surveys, catches ranged from 4.6/net in 2005 to 15.4 in 2011. The 2025 catch of 18.7 fish/trap net was the highest on record. Though increasing trends in bass and panfish have been observed throughout the work area, spring weather conditions during the survey are often as responsible for the variation in catches as are changes in the population. Therefore, net catches should be interpreted cautiously. The fish in 2025 ranged from 2.6 to 9.8 inches and averaged 7.2 inches. The length distribution was good, having nearly 40% of the sample 8 inches or longer.

Nine age-classes were estimated with fish up to age 10. The 2018 and 2019 year-classes represented 31 and 27 percent of the sample in 2025. The 2020 and 2021 year-classes were also well represented in 2025 (combined 33%). Growth was fast compared to lakes with similar habitat. Bluegill attained an average length of 8 inches between the sixth and seventh year of growth. The reduced sunfish bag limit appears to be achieving the goal to maintain a quality Bluegill population.
