The fish population of Marion Lake is dominated by average sized Northern Pike, Largemouth Bass and Bluegill Sunfish. Walleye fry are stocked annually, but abundance remains low. Beginning in 2021 a new regulation for sunfish went into effect and the daily limit from Marion Lake is now 5 sunfish. This regulation is part of the Quality Sunfish Initiative that is working to protect and improve the size of sunfish in our lakes.
