Wyoming’s gold panning laws let you pan recreationally on most open federal public land without a permit, provided you stick to hand tools like pans and non-motorized sluices. That right comes from the General Mining Law, which opens valuable mineral deposits on federal land to exploration by U.S. citizens.1Office of the Law Revision Counsel. 30 USC 22 – Mineral Lands Open to Purchase by Citizens The catch is in the words “open” and “federal.” Wyoming’s creeks run through a patchwork of Bureau of Land Management tracts, national forest, state trust land, private ranches, and wilderness, and the legal status can change every few hundred yards along the same stream.
Private Streambeds Are Where People Get Caught
This is the trap that catches newcomers. In Wyoming, private landowners own the streambed beneath the water, even on rivers you can legally float. The Wyoming Game and Fish Department states it plainly: “You may float across private land on navigable water, but the streambed is the property of the landowner.”2Wyoming Game and Fish Department. Fishing Access – What Is Trespassing Wading, anchoring, or standing on the bottom without permission is trespassing, and panning by definition means scooping material from that bottom.
A creek flowing through alternating BLM and private ground can be legal to work in one spot and a crime fifty feet downstream. Criminal trespass in Wyoming is a misdemeanor carrying up to six months in jail, a fine up to $750, or both.3Justia. Wyoming Statutes 6-3-303 – Criminal Trespass Landowners can give notice by posting signs or by telling you directly. Verify ownership for every stretch of water you plan to work, not just the general area.
State trust land is a separate category. The Board of Land Commissioners controls mineral activity on these parcels under Wyoming Statute 36-6-101, and anything beyond basic recreation needs a temporary use permit or special use lease from the Office of State Lands and Investments.4Justia. Wyoming Code 36-6-101 – Terms of Leases, Extensions, Lessees Specified The office directs anyone interested in mineral collection to contact them first.5Office of State Lands and Investments. Frequently Asked Questions Public access signs on state land usually cover hiking and hunting, not mineral collection.
National Parks and designated wilderness are closed. The National Park Service prohibits collecting rocks, minerals, and gold panning across all park units under 36 CFR 2.1(a) and 2.5(a).6National Park Service. Permits – Geology Wyoming’s Platte River, Savage Run, Encampment River, and Huston Park wilderness areas are closed to mineral entry.7U.S. Forest Service. Gold Panning and Dredging Information
Checking Whether a Spot Is Open
The BLM’s Mineral and Land Records System is the main tool. You can search by legal land description or use the interactive map to see active mining claims, withdrawn lands, and other restrictions.8Bureau of Land Management. Mineral and Land Records System If someone already holds a valid claim where you want to pan, you need their permission. Working an active claim without consent creates a legal dispute, and it’s one you’ll lose.
County assessor maps and GIS portals fill in the private-boundary picture that MLRS doesn’t show. River corridors in Wyoming shift between public and private ground, and the lines on a map rarely match anything visible on the bank. When you can’t tell, call the local BLM field office and ask about the specific stretch.
What Counts as Casual Use
Both the BLM and the Forest Service separate casual recreational panning from regulated mining, and the line is drawn by your equipment and the disturbance it causes.
On BLM land, casual use includes hand panning, non-motorized sluicing, small portable suction dredges, metal detectors, gold spears, and battery-operated drywashers. It does not include mechanized earth-moving equipment, truck-mounted drills, chemicals, or explosives.9eCFR. 43 CFR 3809.5 – Definitions Driving to your site is fine as long as the area is open to vehicle use under the applicable BLM land-use plan.
On National Forest land, the Forest Service exempts gold panning, metal detecting, non-motorized hand sluicing, battery-operated dry washers, and hand-tool specimen collection from any notice requirement, so long as the activity doesn’t cause significant surface disturbance.10eCFR. 36 CFR 228.4 – Plan of Operations, Notice of Intent, Requirements Bulldozers, backhoes, and similar equipment cross the line.
The principle is the same on both: hand-powered or small battery-powered tools with negligible disturbance means no paperwork. Motorized earth-moving or more than trivial ground disturbance means paperwork before you start.
When You Need a Notice or Plan of Operations
BLM Land
Operations that exceed casual use but disturb five acres or less require a notice submitted to the local BLM field office at least 15 calendar days before work begins.11eCFR. 43 CFR 3809.21 – When Do I Have to Submit a Notice BLM can extend review by up to 15 additional days.12eCFR. 43 CFR 3809.312 – When May I Begin Operations After Filing a Complete Notice A financial guarantee covering reclamation costs has to be in place before any ground-disturbing work.13eCFR. 43 CFR 3809.551 – Financial Guarantee Requirements
Operations disturbing more than five acres require a full plan of operations and BLM approval before you begin. Those reviews take longer and usually involve environmental analysis. Splitting a larger project into several notice-level filings to dodge the plan requirement is explicitly prohibited.11eCFR. 43 CFR 3809.21 – When Do I Have to Submit a Notice
National Forest Land
Submit a notice of intent to the District Ranger before any operation that might cause significant surface disturbance. If significant disturbance is likely, you need a plan of operations instead.10eCFR. 36 CFR 228.4 – Plan of Operations, Notice of Intent, Requirements Significance is judged by overall impact, not just equipment size. Starting without authorization produces a noncompliance record that can follow you through future federal land applications anywhere in the country.
Medicine Bow-Routt National Forests
The Medicine Bow-Routt in southern Wyoming is the state’s most popular prospecting area, and the Forest Service has published rules that go beyond the general federal framework. Anyone prospecting there must carry a copy of a Letter of Intent submitted to the Brush Creek-Hayden Ranger District office in Saratoga, regardless of scale.7U.S. Forest Service. Gold Panning and Dredging Information
- Suction dredges and other motorized gear are allowed only from July 1 through September 10, to protect trout spawning. Hand panning is fine year-round.
- Suction hose intake must be three inches or less in diameter; engines must be 10 horsepower or less.
- You cannot excavate into the streambank. Work stays within the stream channel floor. High-banking has to be at least 100 feet from the channel, and any holes must be filled before you leave.
- Only hand panning is allowed on Class I designated waters.
- During low water in late summer, panners and dredgers may be required to maintain 300-foot spacing to control turbidity.
If you can’t meet the six established criteria for recreational dredging in these forests, which include the equipment limits above plus avoiding Blue Ribbon and Wild Trout waters and complying with Wyoming DEQ standards, a formal plan of operations may be required under 36 CFR 228.7U.S. Forest Service. Gold Panning and Dredging Information
South Pass and the Artifact Rule
The South Pass area, about 25 miles south of Lander, is the historic heart of Wyoming gold mining. The BLM manages a 30-square-mile historic mining area accessible from Highway 28 via county roads 515 and 516.14Bureau of Land Management. South Pass Historic Mining Area It contains remnants of five National Historic Trails: the Continental Divide, Oregon, Mormon Pioneer, California, and Pony Express. BLM explicitly warns visitors not to collect or damage trail resources.
That connects to a law that applies anywhere you pan on federal ground. Old bottles, tools, nails, or other objects in a streambed that are at least 100 years old qualify as archaeological resources under the Archaeological Resources Protection Act, and removing them from federal land without a permit is a federal crime. First-offense penalties reach $10,000 and one year in prison. If the combined resource value and site restoration cost exceeds $500, that becomes $20,000 and two years. Repeat offenders face up to $100,000 and five years.15Office of the Law Revision Counsel. 16 USC Chapter 1B – Archaeological Resources Protection
Civil penalties run separately and can reach double the combined value of the resources and restoration costs. Equipment used in the violation, vehicles included, is subject to confiscation. The only explicit exception is arrowheads found on the surface.15Office of the Law Revision Counsel. 16 USC Chapter 1B – Archaeological Resources Protection If something interesting turns up in the gravel, photograph it, note the location, report it to the local BLM office, and leave it where it is.
Clean Your Equipment Between Waters
Wyoming law requires anyone transporting a conveyance, which includes boats and kayaks, to stop at authorized aquatic invasive species check stations. If a peace officer determines an invasive species may be present, they can order decontamination or impound the equipment until it’s done. Refusing or bypassing a check station is a high misdemeanor.16Animal Legal and Historical Center. Wyoming Statutes Article 2 – Aquatic Invasive Species
Even where panning gear isn’t a “conveyance” under the statute, the Medicine Bow-Routt rules require prospectors to thoroughly clean equipment and clothing to prevent whirling disease and non-native organisms like New Zealand mudsnails. Report any suspicious snails or mussels on your gear to the Forest Service or Wyoming Game and Fish Department.7U.S. Forest Service. Gold Panning and Dredging Information Clean, drain, and dry everything before moving between waterways.
Penalties for Getting It Wrong
On BLM land, unauthorized use or occupancy of an unpatented mining claim can bring a fine up to $1,000, up to 12 months in jail, or both. False statements to the BLM carry much steeper penalties: up to $250,000 and five years.17eCFR. 43 CFR Part 3710 Subpart 3715 – Use and Occupancy Under the Mining Laws The government can also sue to shut down unauthorized operations.
On private land, criminal trespass maxes out at six months and $750.3Justia. Wyoming Statutes 6-3-303 – Criminal Trespass The fines sound modest, but the real costs tend to be equipment confiscation, a noncompliance record that follows future federal land applications, and possible civil liability to a landowner or claim holder. Thirty minutes of verification before you leave the house avoids all of it.
