Aquatic invasive species prevention
Aquatic invasive species (AIS) are organisms that significantly harm an ecosystem when introduced. Established AIS can damage natural resources, are nearly impossible to eradicate and costly to manage.
Any watercraft transported into Wyoming from March 1 through November 30 must undergo a mandatory inspection by an authorized inspector before 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 must be inspected by an authorized inspector before launching during ALL months of the year. All watercraft must stop at any open watercraft check station on their route of travel, regardless of previous destination and intention to launch in Wyoming.
Watercraft inspection information
The Wyoming Game and Fish Department conducts watercraft inspections at border locations and major waters around the state. Check stations are marked with signs, and all persons transporting watercraft must stop at these stations.
AIS decal
All watercraft are required to display an aquatic invasive species decal while on the water in Wyoming, with few exceptions. All motorized watercraft and most nonmotorized watercraft require a decal.
Threats
AIS are organisms that are not native and cause significant harm to an ecosystem when introduced. Impacted sectors include municipal water sources, recreation, agriculture, aquaculture and more.
Don't let it loose
Many pets can become invasive species when owners let them loose. Releasing pets can harm the ecosystem, cause problems for your neighbors and be cruel to the animal. Be a responsible pet owner and don't let it loose!
