FAQ
Common Legal Questions
There is no single federal law that explicitly bans or authorizes magnet fishing. In most states, it is technically legal on publicly accessible waterways — but with significant caveats. Army Corps of Engineers managed waterways require compliance with 36 CFR Part 327. State parks often prohibit it entirely or require a permit. Some municipalities have passed specific ordinances. The short answer: legal in most places, but always check local rules first. See our full federal and state overview.
In nearly all U.S. states, a standard fishing license is not required for magnet fishing because it is not considered fishing under fish and wildlife statutes — no bait, lure, or hook is involved, and no fish are targeted. However, South Carolina is a notable exception — it has been the subject of specific guidance from state wildlife officials. Always verify with your state fish and wildlife agency before assuming no license is needed.
Do not take the firearm home. Do not attempt to clean, fire, or disassemble it. In most states, you are legally required to turn it over to law enforcement — transporting a found, potentially stolen, or unregistered firearm can expose you to criminal liability even if your intent was lawful. Call your local non-emergency police line, document the find location with a photo, and let officers take possession. See our complete guide: Found a Gun While Magnet Fishing.
It depends entirely on what you find. Scrap metal, bicycle frames, tools — generally yes. Firearms — no, must be turned over. Items that appear to be historically or archaeologically significant — no, reporting is required under the Archaeological Resources Protection Act (ARPA) or state antiquity statutes. Cash and valuables may be subject to state abandoned property laws. When in doubt, report it. See Historical Artifacts & the Law.
No state has a blanket statewide ban on magnet fishing, but several locations effectively prohibit it: most National Park Service lands, many state park systems (especially in the Northeast), waterways under exclusive Army Corps jurisdiction, and specific municipalities including some Chicago River access points. Indiana passed legislation in 2023 specifically addressing magnet fishing permits on certain state waterways. Always check at the location-specific level, not just the state level.
