2015Rates 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 Moccasin Lake through the year
Northern pike
- Spring
- Pike are in the shallow bays and along new weed growth. At 22 ft of clarity, fish them deeper and lighter than usual.
- Early summer
- Pike are on the outside weed edge and points.
- Summer
- Pike are on the deep weed edge and points near the coolest water they can find. On a lake that drops to 95 ft, check the deep edge of that structure too.
- Fall
- Pike are on the last green weeds and the breaks beside them, feeding heavily as the water drops.
Largemouth bass
- Spring
- Largemouth are moving up into the warming bays and flats, staging around wood, docks and new weeds to spawn. At 22 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 95 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 2025 survey
Moccasin Lake (DOW# 11-0296, Lake Class 32) is a 272-acre lake with 109 littoral acres, 6.1 miles of shoreline, and a maximum depth of 95 feet located west of Longville, MN. A US Forest Service owned concrete public access is located on the eastern shore. The Minnesota Department of Natural Resources has classified Minnesota's lakes into 43 different classes based on physical, chemical, and other characteristics. Moccasin Lake is in Lake Class 32; lakes in this class are characterized as low productivity Sunfish waters. Other area lakes in this class include Cooper, Island, and Long (Pinecrest) Lakes. Moccasin Lake possesses a undeveloped shoreline. The lake is primarily managed for Black Crappie, Bluegill, and Largemouth Bass, and secondarily for Northern Pike and Yellow Perch. An experimental catch and release regulation for Largemouth Bass was implemented in 1996 and made permanent in 2003. A special regulation on Black Crappie and Sunfish was enacted in 2017 (daily limit of five).
Quality angling opportunities exist for Largemouth Bass in Moccasin Lake. An electrofishing survey was completed to evaluate the existing bass regulation. Largemouth Bass abundance was below management goals and lengths ranged from 8 to 18 inches, with an average length of 13 inches. Length based goals for Largemouth Bass were partially met in 2025. Since the regulation has been put in place abundance has fluctuated but average length has not increased.

People can have significant impacts on lakes and the fish populations they support. Harvest, lakeshore development, removal of shoreline vegetation, and introductions of invasive species can all adversely affect fish populations. Currently no aquatic invasive species (AIS) have been identified in Moccasin Lake. AIS are moved from infested to non-infested waters by anglers, boaters, and lake shore owners and can adversely impact lakes and fish populations. To avoid spreading AIS, lake users are required to remove all aquatic plants or animals from their watercraft and drain all water from their boat before leaving the access. If you suspect an infestation of an invasive species in this lake, save a specimen and report it to a local natural resource office. Additional information on all of these topics can be found on the DNR website (www.dnr.state.mn.us) or by contacting the Walker Area Fisheries office.
