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.

Swift Lake is a 357-acre lake with 6 miles of shoreline and a maximum depth of 52 feet located north of Longville, MN. The DNR has classified Minnesota's lakes into 43 different classes based on physical, chemical and other characteristics. Swift Lake is in Lake Class 25; lakes in this class are generally deep, clear and irregularly shaped. Other Lake Class 25 lakes in the Walker Area include Boy, Birch, Blackwater, Girl, Hand, and Inguadona. The lake is primarily managed for Black Crappie and Bluegill, and secondarily for Northern Pike and Yellow Perch. A special regulation for Sunfish and Black Crappie (daily bag limit 10 Sunfish and 5 Black Crappie) was implemented March 2022 as part of the state-wide Quality Sunfish Initiative (QSI) which aims to protect or increase size of Sunfish populations. Black Crappie abundance increased from previous surveys and ranged in length from 4 to 15 inches. Bluegill abundance increased from previous surveys and fish up to 9 inches were sampled. Northern Pike abundance remained within management goals. Lengths ranged from 15 to 36 inches, with an average length of 21 inches and met population size structure goals. Yellow Perch numbers were within management goals, and fish up to 10 inches long were sampled. Other fish species sampled include Bowfin, Brown Bullhead, Hybrid Sunfish, Pumpkinseed, Rock Bass, White Sucker, 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 Swift 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.
