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 Fish 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 57 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 57 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 2020 survey

A targeted survey of the nearshore fish community in Fish Lake was conducted by Fisheries Index of Biological Integrity (IBI) Program Staff starting on July 27, 2020. Ten sampling sites were evenly spaced around the lake and each was sampled by backpack electrofishing and seining with a 15-foot or 50-foot seine, where possible. Backpack electrofishing was completed at all ten sites with three sites sampled from the boat. Similarly, a 50-foot seine was used to sample three sites, a 15-foot seine was used at four sites, and deep, soft sediments prevented the use of seines at three sampling sites. Nearshore sampling captured 19 native species of fish including five species that are intolerant of disturbance (Banded Killifish, Blackchin Shiner, Blacknose Shiner, Iowa Darter, and Least Darter) and one species that is tolerant of disturbance (Green Sunfish).

A summer trap net survey was conducted in conjunction with the targeted survey of the nearshore fish community. Bluegill and Pumpkinseed dominated the trap net catch numbers, but only comprised approximately 46% of total trap net biomass. Of the Bluegills sampled, 50% were between 5 and 7 inches, 6% were over 7 inches and no Bluegills over 8 inches were sampled.

Read the full DNR narrative

These trap net and nearshore survey data are combined with data from an August 2018 gill net survey to describe the fish community and provide a fish-based Index of Biotic Integrity (FIBI) score. The FIBI uses fish community data to measure a lake's health, and the types of fish species present can help identify any stressors that may be negatively affecting the lake environment. The FIBI score, composed of several fish community diversity and composition metrics, indicates the overall health of a lake by comparing it to what is expected for a healthy lake. The FIBI score for Fish Lake is above an impairment threshold for aquatic life use determined for similar lakes and indicates an exceptional fish community is present in this lake. For additional information on the FIBI, search for "lake index of biological integrity" on the mndnr.gov website.

Data from this survey will contribute biological information about the health of the fish community to the Lower St. Croix River Watershed assessment of surface waters process completed in coordination with MN Pollution Control Agency.
