Yes, magnet fishing is legal in Minnesota with restrictions. The activity falls under state waterway regulations and local ordinances, requiring permits for certain waterbodies and prohibiting interference with archaeological resources. The Minnesota Department of Natural Resources (DNR) enforces compliance, while local governments may impose additional rules, particularly near historic sites or conservation areas.
Key Regulations for Magnet Fishing in Minnesota
- Archaeological Protection: Federal and state laws (e.g., the Archaeological Resources Protection Act and Minnesota Statutes § 138.35) prohibit disturbing or removing artifacts from state or federal lands, including lakebeds. Violations may result in felony charges under the 2024 Minnesota Heritage Preservation Act amendments.
- Waterway Permits: The DNR requires a Public Waters Work Permit (MN Rule 6115) for activities altering lakebeds or shorelines, including magnet fishing in designated public waters. Permits are denied if the activity risks ecological damage or conflicts with conservation plans.
- Local Ordinances: Cities like Minneapolis and St. Paul enforce additional restrictions, such as bans in urban lakes (e.g., Lake Calhoun/Bde Maka Ska) under municipal codes. Violators face fines up to $1,000 under local public nuisance statutes.
Enforcement Priorities: The DNR’s 2026 Aquatic Invasive Species Compliance Plan targets gear-related disturbances, while the State Historic Preservation Office monitors unauthorized artifact recovery. Always verify permits via the MN DNR Water Permits Portal before engaging.
