AIS Inspection Stations Help Boaters Comply with Wyoming Regulations


CODY - In an effort to help boaters comply with new aquatic invasive species (AIS) regulations and keep Wyoming waters free from harmful zebra and quagga mussels, the Wyoming Game and Fish Department is operating multiple AIS inspections stations in the Cody area.

Wyoming regulations require that 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 or quagga mussels within the past 30 days is required to undergo a mandatory inspection by an authorized inspector prior to launching year-round.

Greg Mayton, AIS crew leader for the Cody Region said new AIS regulations target out of state boaters rather than resident boaters because boats crossing state lines have a higher potential to be contaminated with aquatic invasive species.

“In the Cody area, Game and Fish operate several AIS inspection stations where watercraft are inspected and sealed,” Mayton said. “All watercraft entering the state must receive an inspection, even if an inspection station they drive past is not open. If you do not get your boat inspected and a seal attached prior to leaving Wyoming, your watercraft must be inspected each time you enter the state.”

“When inspection stations are open, signs will direct vehicles transporting watercraft to the location,” Mayton said. “Although AIS inspection stations are not always busy, they are important to maintain so that out of state boaters have a convenient way to comply with regulations that protect Wyoming waters.”

Information on inspection stations, including location and dates and hours of operation, may be found online at or by calling 1-877-WGFD-AIS. Location and hours of operation of Cody area inspection station are as follows:

Game and Fish operate random AIS inspection stations near major bodies of water in the Cody region. AIS inspections are also available at the Game and Fish Cody Regional office 8 a.m. to 5p.m., Monday through Friday or by appointment.

Boaters who practice drain, clean, and dry will help keep invasive species out of Wyoming. “Invasive mussels can attach to boats as juveniles or adults and larvae can be transported in water in the bilge, live well, or motor of a boat,” Mayton said. “These larvae can infest new waters if watercraft owners do not drain, clean, and dry their watercraft before launching. We recommend boaters drain all water from your boat including the motor, bilge, live well, and ballast areas. Clean all mud, plants, and debris from your boat. The plants can be invasive and mud and plants can also harbor other AIS. Finally, dry your boat well after every use. 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.”
