Watercraft Inspections - What to Expect

The Wyoming Game and Fish Department will conduct watercraft inspections at ports of entry, other border locations, and major waters around the state. These watercraft inspections will be marked with signs and all persons transporting watercraft must stop at these check stations. Inspections will consist of an authorized inspector asking a few questions to determine the risk your watercraft poses of transporting AIS. If your watercraft is drained, cleaned, and dried, you can expect your inspection to go quickly, an estimated 3 to 5 minutes at the most. The majority of Wyoming boaters can expect this low-risk inspection. If you are determined to be high-risk, the inspection is more thorough and may take 10 to 30 minutes depending on the type and size of watercraft. Thorough high-risk inspections are critical to keeping AIS out of Wyoming. Once your watercraft has passed inspection, you are free to launch your boat.

Any watercraft transported into Wyoming from March 1 through November 30 must undergo a mandatory inspection by an authorized inspector prior to launching in any water of the state. 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.


Watercraft Decontaminations - What are they?

If your watercraft is determined to need decontamination an authorized inspector will thoroughly spray the exterior and flush the interior compartments with scalding (120-140 degrees F) water to remove and kill any AIS that may be on the watercraft. After decontamination, the watercraft will be inspected again to ensure the decontamination was successful. Watercraft that is heavily infested with AIS may require a quarantine to kill any AIS that may not have been killed during decontamination. Very few boats (<1%) will need to undergo decontamination.
