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 Forest 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 67% 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.
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. With 67% of this lake 15 ft or shallower, the weed edge is the main event.
- 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
Forest Lake is a 2,251 acre lake comprised of three distinct basins and assigned to lake class 24. There are three public boat accesses available on the lake resulting in high recreational use. Zebra Mussels were discovered in 2015. The primary management species in the lake are Walleye and Muskellunge both of which are maintained through stocking. Walleyes fingerlings are stocked annually on a variable schedule of either 995 or 1531 pounds. Muskellunge are currently stocked with a target quota of 766 fingerlings per year. The lake was sampled with gill nets and trap nets in July 2025 primarily to assess the Walleye population and provide fish composition information to be used in an Index of Biotic Integrity survey. The previous survey was conducted only with gill nets in 2023.
Walleye were sampled at a rate of 7.9 fish per gill net. Fish size was larger than average for the lake class but similar to previous surveys with a mean length of 19 inches. Lengths ranged from 7.5 to 27 inches and were well distributed within that range. Ages ranged from 1 to 15 years with 7 year olds being the most abundant having twice as many sampled as any other year class. Growth appears to be adequate with age and size distributions offering quality angling opportunities.
Read the full DNR narrative
Northern Pike were sampled at a rate of 11.8 fish per gill net. This was substantially higher than the previous survey catch rate of 4.5 fish per gill net and was the highest rate sampled in the history of the lake. Fish size did not diminish with a mean length of 25.6 inches. Fish lengths ranged from 10 to 36 inches with 11% of the catch exceeding 30 inches.
Yellow Perch were sampled at a rate of 13.6 fish per gill net. This was a substantial increase over the previous survey's rate of 6.3 fish per gill net and is a more typical catch for both the lake and the lake class. Size remained small with a mean length of 6.2 inches and a maximum length of 8 inches.
Although summer trap nets were used to sample both Bluegill and Black Crappie populations for an Index of Biotic Integrity survey, spring panfish trap net surveys are best for describing Minnesota's panfish populations. Similarly, one 43.5 inch Muskellunge was sampled in trap nets but their population is better evaluated by separate spring surveys. Other species sampled during this survey were: Black Bullhead, Brown Bullhead, Common Carp, Hybrid Sunfish, Largemouth Bass, Pumpkinseed, Rock Bass, and Yellow Bullhead.
