Is Magnet Fishing Legal? The Laws That Actually Apply, State by State
Magnet fishing is legal in most places by omission: few laws mention it. But South Carolina prohibits it in its waterways, Oklahoma bans it in every state park, Indiana requires a permit on DNR property, and national parks ban it under the same rule as metal detectors. Here are the layers of law that decide whether you can throw a magnet, and what you can keep.
Most state codes never mention magnet fishing. Where nothing addresses it — Texas is a documented example — it's treated as an ordinary use of public water. But "no law against it" isn't the same as "allowed everywhere". Whether you can magnet fish at a given spot depends on four layers, from the narrowest to the broadest:
- The landowner's rules. State parks, wildlife areas, city parks and federal agencies can ban or permit it on their own property, even where the state is silent.
- State antiquities law. Many states own historic material on their submerged lands, and pulling it up without a permit is a crime, magnet or not. South Carolina's version is strict enough that the state treats magnet fishing itself as prohibited.
- Federal land rules. National park units ban it outright; Army Corps lakes don't address it.
- Ordinary local rules on bridges, swimming and littering, which shape how you can fish and what you do with the junk.
This page covers the specific rules we've verified. It is not a list of all 50 states: where a state isn't listed, we haven't found a statewide rule, which is not the same as confirming there isn't one. Check the land manager for the exact water you plan to fish.
Magnet fishing rules we've verified
| Where | Status | Rule |
|---|---|---|
| South Carolina — all state waterways | Prohibited | SCIAA: "Activities such as Magnet Fishing are prohibited in South Carolina waterways and SCIAA does not issue Hobby Licenses for this potentially destructive practice." The Underwater Antiquities Act's Hobby License allows hand recovery only (S.C. Code Title 54, Chapter 7). See Congaree River |
| Oklahoma state parks | Prohibited | Oklahoma State Parks FAQ: "Magnet fishing and metal detecting are prohibited at all state parks." |
| Indiana DNR properties | Free permit required | Indiana DNR: "A permit is required to magnet fish on Indiana DNR properties. Permits are free and issued at the discretion of individual properties." Magnets must be retrievable by hand, without motorized equipment |
| National Park Service units | Prohibited | 36 CFR 2.1(a)(7) bans using metal detectors and other location devices; Cape Hatteras National Seashore's compendium confirms magnet fishing falls under it. See our 36 CFR 2.1 guide |
| Army Corps of Engineers lakes | Unclear — ask the project office | 36 CFR 327.14 allows metal detectors on designated beaches and bars removing public property, including historical and archaeological features, without the District Commander's permission; magnet fishing isn't named. See Lake Texoma |
| Texas (state law) | No statute addresses it | Local rules still apply: in Austin, swimming in Lady Bird Lake and fishing from bridge decks over the river are banned. See Lady Bird Lake |
Checked October 2026 against SCIAA's Hobby License page, Oklahoma State Parks' FAQ, Indiana DNR's magnet fishing page, 36 CFR 2.1 and 327.14, and the Site pages linked. Park and agency rules change; confirm with the manager of the water you plan to fish.
What you pull up: state ownership of submerged history
Even where magnet fishing is allowed, old objects from public water may not be yours to keep. Several coastal states claim historic material on their submerged lands:
- Florida: objects abandoned on state sovereignty submerged land belong to the state, and removing them without a permit is a crime (Fla. Stat. §§ 267.061, 267.13). See our Florida Chapter 267 guide.
- Texas: the Antiquities Code makes pre-twentieth-century wrecks and "treasure imbedded in the earth" on state land, tidelands, submerged land and riverbeds state property. See our Texas Antiquities Code guide.
- North Carolina: shipwrecks, cargo and underwater artifacts unclaimed for more than 10 years on the state's navigable bottoms belong to the state (G.S. 121-22), and recovering them needs a state permit (G.S. 121-25).
- South Carolina: the Underwater Antiquities Act reserves submerged archaeological and paleontological material to licensed hand recovery — the reason magnets are out entirely.
Modern junk — bike locks, fishing lures, last year's lost keys — isn't what these laws protect. A Civil War shell, an old anchor or a cannonball is.
Ordnance and firearms: don't handle them
Magnets find live ammunition, grenades and old artillery shells, and some rivers have documented histories of dumped ordnance — in Columbia, South Carolina, Union troops dumped Confederate munitions into the Congaree in 1865, and a cleanup there recovered live ammunition. If you pull up anything that looks like a shell, grenade or explosive, set it down gently, move away, and call 911. If you recover a firearm, don't clean it or take it home: Indiana DNR, for one, asks magnet anglers to report firearms and other dangerous items, which may be evidence in a criminal investigation. Call the local police non-emergency line or the property office.
Before you throw a magnet anywhere
- Identify who manages the water and the bank: city, county, state park or wildlife area, Army Corps, National Park Service or private owner
- Check that manager's rules for magnet fishing specifically; ask for a permit where one exists (Indiana DNR properties)
- Don't magnet fish anywhere in South Carolina's waterways, in Oklahoma state parks or in national park units
- Check local bridge-fishing, swimming and wading rules before you rely on them to free a snag
- Treat anything historic as the state's until you know otherwise, and report significant finds
- Call 911 for anything that could be ordnance; report firearms to police
- Carry out and dispose of the scrap you pull up
Frequently Asked Questions
Is magnet fishing legal in the US?
Generally yes where no rule addresses it, but not everywhere. South Carolina prohibits it in its waterways (SCIAA), Oklahoma bans it in all state parks, Indiana requires a free permit on DNR properties, and national park units ban it under 36 CFR 2.1(a)(7). Many land managers set their own rules, so check the specific water.
Why is magnet fishing illegal in South Carolina?
South Carolina's Underwater Antiquities Act limits recreational recovery from state waters to licensed hand collection, and SCIAA, which administers the Hobby License, says magnet fishing is prohibited in South Carolina waterways and issues no license for it. A 2025 bill (H.4398) to allow it under a license had not been enacted as of mid-2026.
Can I magnet fish in a national park?
No. 36 CFR 2.1(a)(7) prohibits metal detectors and other location devices in national park units, and Cape Hatteras National Seashore's compendium confirms magnet fishing falls under that rule.
Do I need a fishing license to magnet fish?
None of the agency rules we verified treats magnet fishing as angling or requires a fishing license for it. Indiana requires a separate, free magnet fishing permit on DNR property. Check the state and the land manager where you plan to fish.
Can I keep what I find magnet fishing?
Modern items, usually yes, where the activity is allowed. Historic items from public water may belong to the state: Florida, Texas, North Carolina and South Carolina all claim historic material on their submerged lands, and removing it without a permit can be a crime. Firearms and ordnance should be reported, not kept.
