FISHING AND BOATING

AIS Boating Information

Before you bring a watercraft into Wyoming...


Regulations to Protect Wyoming's Resources

• Any watercraft transported into Wyoming from March 1 through November 30 must undergo a mandatory inspection by an authorized inspector prior to launching.  Any watercraft that has been in a water infested with zebra/quagga mussels within the last 30 days is required to undergo a mandatory inspection by an authorized inspector prior to launching during ALL months of the year.

• Any person transporting a watercraft into Wyoming from March 1 through November 30 who did not encounter a mandatory aquatic invasive species check station prior to reaching a water of the state may launch without further inspection if the watercraft has a properly affixed seal applied by an authorized inspector (from Wyoming or other state AIS program) and is accompanied by a valid seal receipt during transit. The person transporting the watercraft may remove the seal immediately prior to launching on the destination water and must retain the seal and valid seal receipt while on the water. Other states have inspection information and locations, contact their offices for details. 

• Any watercraft that HAS BEEN in a water infested with zebra/quagga mussels within the last 30 days, is required to undergo a mandatory inspection by an authorized inspector prior to launching during ALL months of the year. Waters positive for AIS are often posted at boat ramps and launches. A list of waters suspect or positive for invasive mussels and other information is available here.

• Any watercraft transported into Wyoming from December 1 through the last day of February that HAS NOT been in a water infested with zebra/quagga mussel within the past thirty (30) days and did not encounter a mandatory aquatic invasive species check station prior to reaching a water of the state, may launch without a mandatory inspection.

• Boat Inspections: All boaters must stop at established check stations. Check stations are established at ports of entry, border locations, or at boat ramps and are set up to ensure watercraft are clean, drained, and dry before launching. Inspections are also available at WGFD Regional Offices during normal business hours. A list of locations and operation hours is here: Watercraft Inspection Locations.

• All watercraft must have a valid Wyoming AIS decal before boating on any waters of the state. Decals are available online, at regional offices, and at automated license vendors. A digital screenshot of your receipt purchased online will suffice.

• All visible vegetation must be removed from a watercraft/trailer once it leaves the water. Boaters must drain all water from watercraft, including all compartments, after leaving a water. All bilge/ballast/live well plugs must be removed from the watercraft while transported by land in the state.
