Recreational boating can spread aquatic invasive species when species become attached to the boat or survive in water carried on boats and are moved from one water to another.
Invasive mussels can survive as larvae in just a small amount of water carried in a boat, and juveniles and adults can actually attach to the outside of a boat and move to a new location.
Invasive plants can attach to boats as small fragments that often get tangled in the propeller, and that one small piece can start a whole new invasive plant population at the next water that boat launches at.
Boaters, you can STOP THE SPREAD by following these three easy steps after you boat:
1. DRAIN all water from your boat including the motor, bilge, live well, and ballast areas.
2. CLEAN all mud, plants and debris from your boat. The plants can be invasive and mud and plants can also harbor other AIS.
3. DRY your boat well before using it in another water. We recommend drying it for at least 5 days in the hot summer, 18 days in the spring or fall, or 3 days in the winter when temperatures are freezing.
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.
