Boat Access:

Access to this lake is in Casperson Park, operated by the City of Lakeville. This lake has surface water use restrictions. See sign at the access. 

Shore Fishing:

Anglers may fish from shore and the fishing pier in Casperson Park and along the walking/bike path leading from the park along the west shore of the lake. This is only public property as far as the first bridge over the inlet from the old northern pike spawning area, beyond that point it is private property on the lakeshore and does not provide public access for fishing. Please respect private property and do not fish beyond the first bridge.

Anglers may also fish from shore in Antlers Park, located on the southeast bay of the lake. There is a small fishing dock at this location.

The Department of Transportation maintains a fishing platform at a site off the east frontage road of I-35 in the northeast arm of the lake. This site is limited by shallow water and abundant vegetation. 

Special Regulation:

This lake has a special regulation of a 5-fish daily limit for Sunfish.

Management Plans:

  1. Fisheries standard lake survey in 2023.
  2. Stock 454,000 Walleye fry annually.
  3. Monitor winter oxygen levels as needed; operation of winter aeration system by the city as needed.

Aquatic Invasive Species Alert:

This lake contains Eurasian watermilfoil and zebra mussels. Remove any visible plant material from your boat, trailer and boating equipment before you leave the lake and drain all water before leaving the boat access. 


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.
