History & Status of the Fishery
Three Island is a 288-acre lake with 7 miles of shoreline and a maximum depth of 13 feet located east of Walker, MN. A US Forest Service owned public access is located on the north shore. The DNR has classified Minnesota's lakes into 43 different classes based on physical, chemical and other characteristics. Three Island Lake is in Lake Class 37. Lake Class 37 lakes are small, shallow, eutrophic lakes. Other area lakes in this class include Cedar, Horseshoe, Jackpine, Little Woman and Twenty-Six. Most of shoreline on Three Island Lake is publicly owned and undeveloped. The lake is primarily managed for Black Crappie, Bluegill, Northern Pike and Largemouth Bass and secondarily for Yellow Perch. Low dissolved oxygen observations in Three Island Lake during some winters suggests the potential for winterkill to occur. No fish kill has been confirmed at ice out and surviving fish have responded with strong reproduction, indicating if a kill is occurring it is partial.
Three Island Lake is a multi-species lake that offers fishing in a wild scenic setting. Black Crappie were abundant with fish from 4 to 13 inches sampled. Management goals are still being developed for this species. Bluegill were caught in moderate numbers not meeting the management goal with fish from 3 to 8 inches sampled. Northern Pike were very abundant and were caught in numbers above the management goals set for this lake with fish from 9 to 27 inches sampled, however size goals for Northern Pike were met. Yellow Perch caught in low numbers not meeting the management goal. Yellow Perch were sampled from 5 to 9 inches.
Other fish species that anglers can expect to encounter include, Hybrid Sunfish and Pumpkinseed.
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 Three 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.
