Leech Lake Fishing guide

The current Walleye regulation on Leech Lake is a 4 fish limit with no more than 1 Walleye over 20" allowed in possession which went into effect in 2019. This regulation change was made with the objective to bring down the number of female spawners into the optimal reproductive range for the lake and provide additional harvest opportunity to anglers. It is also intended to provide relief to the prey base and allow time for the Yellow Perch population to recover following a decade of repressed abundance. The regulation is evaluated annually and adjustments will be made based on management plan objectives and action items.

A Black Crappie possession limit of 5 and Sunfish possession limit of 5 went into effect in 2021 as part of the statewide Quality Panfish Initiative. This regulation will be evaluated utilizing future creel surveys and targeted spring sampling. The regulations are intended to reduce exploitation and maintain quality size structure of both species.

Updates on specific species are provided below:

Walleye: Since standardized sampling began in 1983, Walleye gill net catch rates have ranged from 4.6 fish/net (1993) to 13.4 fish/net (1988). The 2025 catch rate was 5.8 fish/net. Walleye abundance is being driven by the historically large 2021-year class, now measuring 17 - 21 inches, and the 2023-year class, now measuring 13 - 16 inches. Walleye sampled in gill nets ranged in length from 8 to 26.5 inches and included several year classes that are large enough to harvest. Twenty-four percent of the Walleye in the 2025 sample were over 20 inches.

Northern Pike: The gill net catch rate of Northern Pike was 3.3 fish/net. Northern Pike gill net catch rates have remained relatively stable since 1983, ranging from 3.3 fish/net (2022) to 6.2 fish/net (1995) with an average of 4.6 fish/net. Northern Pike ranged in length from 15 to 31 inches. There is a 10 fish possession limit on Northern Pike, with a 22-26" protected slot limit and only 2 over 26" allowed in possession. There is an exception for the protected slot allowing one fish within the slot taken by spearing in the winter.

Muskellunge: Leech Lake possesses a premier muskellunge fishery known for its trophy size potential. Identification of the Leech Lake Proper genetic strain in 1989 earned its use for statewide rearing. A spawn take operation is done every four years on Leech Lake to introduce new genetics into brood source lakes. The most recent operation was completed in 2025. Muskellunge sampled ranged in length from 25 to 52 inches.

Yellow Perch: Gill net catch rate was 13.5 (fish/net) in 2025. Historical catch rates have ranged from 8.1 fish/net (2023) to 37.7 fish/net (1995). Yellow Perch sampled ranged from 5 to 13 inches with 46 percent of perch 8 inches or larger.

Tullibee (Cisco): The 2025 gill net catch rate was 2.2 fish/net. Catch rates have ranged from 0.6 fish/net (2006, 2023) to 18.5 fish/net (1987). Tullibee sampled ranged from 8 to 16 inches. Within the Leech Lake Reservation, the Whitefish limit is 25 and the Tullibee (Cisco) limit is 50, which is an exception to the statewide regulation. Daily and possession limits are the same.

Bass: A targeted panfish and bass assessment were completed in 2012, 2015, 2018, and 2022. The next assessment is scheduled for the spring of 2026. Catch rates of Largemouth Bass larger than 15 inches were similar among years (range: 3 to 6 fish/hour). Lengths in 2022 ranged from 7 to 18 inches. Anglers can find quality bass fishing opportunities in the beds of mixed vegetation in most major bays.

Bluegill: The spring electrofishing catch rate for Bluegill (67 fish/hour) in 2022 was higher than in 2018 (30 fish/hour) and 2015 (46 fish/hour). Lengths sampled in 2022 ranging from 2 to 10 inches; 20 percent of the Bluegill sampled were over 8 inches long.

Black Crappie: Spring electrofishing catch rates for all Black Crappie were 11 fish/hour in 2022, compared to 4 fish/hour in 2018. Lengths in 2022 ranged from 4 to 14 inches and 37 percent were 10 inches or longer.

Aquatic invasive species currently found in Leech Lake include Banded Mystery Snails, curly-leaf pondweed, Eurasian watermilfoil, Heterosporosis, purple loosestrife, Rusty Crayfish, starry stonewort and Zebra Mussels. Other aquatic invasive species such as Spiny Water flea are increasing in prevalence throughout Minnesota and pose a likely risk but have not been found in Leech Lake to date. Anglers and boaters alike are encouraged to review and adhere to rules requiring proper bait disposal, draining all water from bait containers, live wells, bilge, and the watercraft, and properly inspecting and removing all plants and animals from the watercraft, anchor, and trailer when leaving a lake. Information on invasive species and prevention can be found by searching MN DNR invasive species in your preferred internet search engine or by calling your local DNR office.
