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 Man Lake through the year

Walleye

Spring
Walleye are shallow, on and just off the spawning flats and the first green weeds. At 11.9 ft of clarity, fish them deeper and lighter than usual.
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 93 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. At 11.9 ft of clarity, fish them deeper and lighter than usual.
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 93 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 2022 survey

A targeted survey of nearshore fish species in Man Lake was conducted on July 5-7, 2022, by DNR Index of Biological Integrity (IBI) Program staff. Sampling sites were evenly spaced around the lake, and each was sampled by backpack electrofishing and seining with a 50-foot or 15-foot seine, where possible. Backpack electrofishing was completed at all sampling stations. Similarly, a 50-foot seine was used to sample nine stations and site conditions prevented the use of seines at one station due to thick submergent and emergent vegetation. Nearshore sampling captured 15 species of fish including five species that are intolerant of disturbance (i.e., Banded Killifish, Iowa Darter, Mottled Sculpin, Rock Bass, and Smallmouth Bass) and none that are tolerant of disturbance.

A summer trap net survey was also conducted by IBI Program staff on July 5-6, 2022. Nine trap nets were set along the shoreline in locations that encompassed multiple habitat types. Trap net sampling captured six species of fish, including one that is intolerant of disturbance (i.e., Rock Bass). Bluegill comprised a majority of the catch by number and by biomass.

Read the full DNR narrative

The nearshore and trap net were combined with gill net data from a 2019 survey to describe the fish community and provide a Fish-based IBI (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. In Minnesota lakes, certain fish species cannot survive without clean water and a healthy habitat (e.g., Iowa Darter, Banded Killifish, and Smallmouth Bass), while other species are tolerant of degraded conditions (e.g., Black Bullhead, Common Carp, Fathead Minnow). 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. For additional information on the FIBI, search for "lake index of biological integrity" on the mndnr.gov website.

Results from this survey indicate that the fish community in Man Lake is healthy as indicated by an FIBI score that meets the exceptional use threshold determined for similar lakes. Data from this survey will contribute biological information about the health of the fish community to the Leech Lake River Watershed assessment process in coordination with MN Pollution Control Agency.
