A. At an AIS check station, an authorized inspector will ask a few questions to determine the risk your watercraft poses of transporting AIS. If the watercraft is deemed low-risk, the watercraft owner will be provided informational materials, the watercraft will be briefly inspected, and allowed to launch. A watercraft deemed high risk will need to undergo a more thorough inspection. High-risk watercraft may include those that last operated their watercraft in a state with waters known to have invasive mussels, or watercraft with a large amount of standing water which could harbor larval mussels.

A. Permanent inspection locations will be established from mid- April through mid-September each year at many ports of entry and other border locations. Inspectors will also be present at major waters on a rotating basis. Wyoming Game and Fish Department (WGFD) regional offices can also provide inspections by appointment during normal business hours. Details on inspection locations and hours of operation can be found by clicking the link below. AIS Watercraft Inspection Locations

A. A standard inspection will take 3-5 minutes. A high-risk inspection is more thorough and may take 10-30 minutes depending on the type and size of watercraft.

A. Before and after you launch in Wyoming, make sure you follow the Drain, Clean, and Dry procedure. Transporting a clean and dry watercraft will allow you to quickly move through the inspection process. One tip, leave the bilge plug out until you reach the boat ramp. Drain Clean Dry Procedure

A. Yes, all persons transporting watercraft must stop at authorized AIS check stations that are established on their route of travel.

A. An authorized inspector will thoroughly spray the exterior and flush the interior compartments with scalding (140 degrees F) water to remove and kill any AIS that maybe on the watercraft. After decontamination, the watercraft will be inspected again to ensure the decontamination was successful. Watercraft that are heavily infested with AIS may require a quarantine to kill any AIS that may not have been killed during a decontamination.

A. No. Only an authorized inspector can decontaminate watercraft in Wyoming. In addition,the water used at car washes does not reach the high temperatures needed to kill AIS, and the effluent may drain into a water and spread any AIS washed from the watercraft. It is best to decontaminate watercraft on a dirt or gravel surface where the effluent water can evaporate.
