Glendo check station AIS inspection

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.
