Magnet Fishing Laws in Minnesota
State agency rules, waterway access, state park policy, and what happens when you find something significant.
State Agency & Regulatory Framework
Minnesota's extensive public water access system — over 4,000 public water access sites — provides a large number of legally clear access points for magnet fishing. DNR manages 1,300 wildlife management areas with waterway access. Minnesota's antiquity laws protect archaeological resources on public land. Found firearms must be reported to local law enforcement under Minnesota Statute § 609.523.
State Park Policy
Minnesota State Parks has not prohibited magnet fishing. DNR-managed public access areas on lakes and rivers generally follow general recreation rules in designated fishing areas.
Waterway Access & Navigability
Minnesota has among the strongest public trust doctrine for water access in the country, covering all navigable waters and virtually all lakes with public access. The state manages thousands of public water access sites (boat launches) throughout the state.
If You Find a Firearm
Regardless of Minnesota state law details, the protocol for a firearm find is consistent: do not transport it, call the local non-emergency police line immediately, document the find location, and turn it over to the responding officer. Request a case number. For the full protocol, see: Found a Gun While Magnet Fishing.
