History & Status of the Fishery
Island Lake is a 358-acre lake with 5.8 miles of shoreline and a maximum depth of 45 feet located southeast of Longville, MN. A county owned public access is located on the west shore. The DNR has classified Minnesota's lakes into 43 different classes based on physical, chemical and other characteristics. Island Lake is in Lake Class 23; lakes in this class are generally deep and clear. Other area lakes in this class include Jack, Ponto, Stony, and Baby Lake. The lake is primarily managed for Northern Pike and Largemouth Bass and secondarily for Black Crappie, Bluegill, and Walleye.
Island Lake provides multi-species angling opportunity and a game fish community dominated by sunfish and Northern Pike. Though Northern Pike abundance was below the management goal, size goals were met in 2022 highlighting quality size structure. Sampled pike ranged in length from 10 to 34 inches. Black Crappie abundance and size exceeded management goals and ranged in length from 4 to 13 inches. Largemouth Bass averaged 12 inches long and abundance was low. Sampled Bluegill exceeded size goals with fish measuring up to 9.5 inches and most exceeding 6 inches in length. Walleye abundance in Island is low and lengths ranged from 13 to 24 inches long.
Other fish species that anglers can expect to encounter include Bowfin, Brown Bullhead, Green Sunfish, Hybrid Sunfish, Pumpkinseed, Rock Bass, and Yellow Bullhead.
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 Island 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.
