Catch per net (CPUE) is the DNR survey's count per gill net or trap net set; higher means more of that species were sampled, not a fishing forecast. Top species per gear shown; where we have no verified common name for a DNR code, the code itself is shown.

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.
