Magnet fishing is legal in Indiana. No single statute governs the hobby, so the rules come from a mix of property law, archaeology protections, and environmental code. The one piece almost everyone misses: if you want to fish on any property owned, managed, or leased by the Indiana Department of Natural Resources, you need a free permit before your magnet touches the water.
The DNR Permit on State Property
The permit itself costs nothing, but there’s no central application. Each DNR property issues its own, so you contact the specific property office where you plan to fish and request permission there.1Indiana Department of Natural Resources. Magnet Fishing on State Properties
DNR properties also limit your equipment. The magnet and whatever you catch on it have to come up by hand, with no motorized assistance. No winches, no ATVs pulling rope, no boat-mounted retrieval rigs. If your own arms can’t lift it, it’s not allowed on DNR water.1Indiana Department of Natural Resources. Magnet Fishing on State Properties
You do not need a standard Indiana fishing license to magnet fish, since you aren’t catching fish. The DNR permit is a separate requirement, and it applies only on DNR land.
City Parks, County Reservoirs, and Other Public Waters
Plenty of Indiana water sits outside DNR control. City parks, county reservoirs, and municipal waterways run on their own rules, and the DNR’s own guidance tells you to check with the property manager or owner before you drop a magnet.1Indiana Department of Natural Resources. Magnet Fishing on State Properties
Local ordinances are all over the map. Some parks ban any in-water activity. Others say nothing about magnet fishing at all. Posted signs are a starting point, but a quick call to the local parks department or a look at the municipal code online is a safer check. Legal on a state fish and wildlife area does not mean legal in your town’s park.
Private Land and Navigable Water
Magnet fishing on private property without the owner’s explicit permission is trespassing. That covers private ponds, creeks that cross someone’s land, and bridges posted with no-trespassing signs. Written permission is ideal; a verbal okay is legally sufficient but hard to prove in a dispute.
Access gets confusing because some Indiana rivers and streams are publicly navigable even where the banks are privately owned. Standing on a public bridge and dropping a magnet into a navigable waterway is generally fine. Walking across someone’s farm to reach that same creek is not. When the access route is unclear, ask.
Federal Land
Federal property in Indiana, including Hoosier National Forest and the wildlife refuges, falls under the Archaeological Resources Protection Act. That law bars removing archaeological resources from public lands without a permit.2GovInfo. 16 USC 470ee – Prohibited Acts and Criminal Penalties The Bureau of Land Management puts it plainly: no removing, damaging, or disturbing cultural materials, which can include old bottles, metal tools, horseshoes, and historic coins.3Bureau of Land Management. Can I Keep This The permit process is built for researchers, not hobbyists, so federal land is best avoided for this hobby.
The 1870 Cutoff for Artifacts
Indiana Code 14-21-1 defines an artifact as an object made, modified, or used before December 31, 1870, or nonportable evidence of human activity formed before that date.4Indiana General Assembly. Indiana Code 14-21-1-2 – Artifact Defined A Civil War-era canteen pulled from a river bottom is a protected artifact under this definition. A 1920s car part is not.
The protection applies on public and private land alike. Deliberately disturbing the ground to uncover artifacts or human remains from before that date requires an approved plan from the DNR. Doing so without one is a Class A misdemeanor, and disturbing human remains in the process pushes the charge to a Level 6 felony.5Justia. Indiana Code Title 14, Article 21, Chapter 1 – Historic Preservation and Archeology
Possession is treated just as seriously. Knowingly receiving, keeping, or selling an artifact, burial object, or human remains taken in violation of this chapter is a Level 6 felony, and it rises to a Level 5 felony if the archaeological damage exceeds $100,000 in remediation costs.5Justia. Indiana Code Title 14, Article 21, Chapter 1 – Historic Preservation and Archeology
If You Pull Up Something You Weren’t Expecting
Firearms or Explosives
Guns and old ordnance come up more than people expect. On DNR property, contact the property office or call the DNR Division of Law Enforcement Central Dispatch at 812-837-9536.1Indiana Department of Natural Resources. Magnet Fishing on State Properties Elsewhere, call 911. Do not try to disassemble, clean, or transport anything that looks like a firearm or munition. Set it down, step back, and wait for law enforcement.
An Accidental Artifact
If you accidentally uncover an artifact or burial object, meaning you weren’t searching for archaeological material, state law requires two steps. Stop all activity within 100 feet of the find, and notify the DNR within two business days. Failing to stop and report is a Class A infraction. The DNR then has ten business days to authorize you to continue, impose conditions, or require an approved plan before any further activity.5Justia. Indiana Code Title 14, Article 21, Chapter 1 – Historic Preservation and Archeology
Human Remains
Human remains carry stricter obligations. Notify the DNR within two business days. The remains must be treated or reburied according to rules set by the Indiana Historic Preservation Commission or a court order. Disturbing buried human remains or grave markers without an approved plan, or in violation of one, is a Level 6 felony regardless of intent.5Justia. Indiana Code Title 14, Article 21, Chapter 1 – Historic Preservation and Archeology
Haul Out Your Junk
Rusty bolts, broken tools, corroded scrap. Leaving any of it on the bank is littering. The baseline offense is a Class B infraction, but refuse left within 100 feet of a waterway under DNR or Army Corps of Engineers jurisdiction is a Class A infraction with a fine of up to $1,000.6Indiana General Assembly. Indiana Code 35-45-3-2 – Littering Nearly every magnet fishing spot sits inside that 100-foot zone, which means the higher tier is the one you need to care about. Bring a bucket or trash bag and take everything with you. Many municipalities have free scrap metal drop-offs.
Selling Scrap and Taxes
If you accumulate enough metal to sell, Indiana’s valuable metal dealer law adds paperwork. Dealers must collect your photo ID, record your name, address, driver’s license number, the vehicle you used, and a description of the material, and photograph you and the metal.7Justia. Indiana Code Title 25, Article 37.5, Chapter 1 – Regulation of Valuable Metal Dealers That record exists so stolen material can be traced, so stick to obviously discarded scrap and skip anything that looks recently placed or suspiciously intact.
The IRS treats found property as taxable income. Under Publication 525, if you find and keep property that doesn’t belong to you, you owe tax on its fair market value in the year you found it.8Internal Revenue Service. Publication 525 – Taxable and Nontaxable Income For most hauls, the fair market value rounds to zero and there’s nothing to report. If you ever pull up something genuinely valuable, report it as other income whether you sell it or keep it.
