If you are transporting watercraft into Wyoming from March 1 through November 30, your watercraft MUST be inspected before launching in Wyoming. At all other times of the year, your watercraft must be inspected if it has been on any water known to be infested with zebra or quagga mussels within the last 30 days. If you encounter a watercraft check station on your route of travel it is also mandatory that you stop and have your watercraft inspected for AIS. Details on inspection locations and hours of operation can be found by clicking the link below. AIS Watercraft Inspection Locations
