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 Big 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 42 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 42 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.

MN DNR · in their words

From the 2017 survey

A targeted survey of nearshore fish species in Big Lake was conducted on June 19, 2017 by 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 ten sampling stations, but three stations were sampled from the boat due to site conditions. Similarly, a 50-foot seine was used to sample seven stations and site conditions prevented the use of seines at three stations. Nearshore sampling captured 22 species of fish including six species that are intolerant of disturbance (Banded Killifish, Blackchin Shiner, Blacknose Shiner, Iowa Darter, Least Darter, and Pugnose Shiner) and one that is tolerant of disturbance (Green Sunfish).

The nearshore data were combined with trap net and gill net data from an August 2017 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. Blacknose Shiner, Iowa Darter, and Rock Bass), while other species are tolerant of degraded conditions (e.g. Black Bullhead, Common Carp, and Green Sunfish). 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.

Data from this survey indicates Big Lake is in exceptional health as indicated by an FIBI score well above the impairment threshold for aquatic life use determined for similar lakes. Data from this survey will contribute biological information about the health of the fish community to the Sauk River Watershed assessment process in coordination with MN Pollution Control Agency.

Frequently asked questions

How deep is Big Lake?

Big Lake reaches 42 ft at its deepest point with a mean depth of 14.6 ft; about 50% of the lake is littoral (15 ft or shallower).

How big is Big Lake?

Big Lake covers 458 acres with about 7.5 miles of shoreline.

How clear is the water in Big Lake?

What fish are in Big Lake?

Minnesota DNR surveys (most recently 2017) record walleye, largemouth bass, smallmouth bass, northern pike, bluegill, crappie, yellow perch, channel catfish.

Is Big Lake stocked?

Yes. The DNR stocked black crappie and walleye in 2025; the stocking table on this page lists every year back to 2017.

Does Big Lake have a public access?

Yes. Big Lake has one public access site: Big Lake (trailer launch).

How big do walleye get in Big Lake?

The biggest walleye measured in recent DNR surveys taped 26"; the size-history table on this page tracks the biggest fish in each survey back to 1994.

When was Big Lake last surveyed?

The Minnesota DNR last surveyed Big Lake in 2017, the most recent of 8 surveys on record. A survey that old is a starting point, not a current reading.
