Aquatic invasive species are non-native organisms that can cause significant harm to an ecosystem when introduced. Aquatic invasive species, like zebra and quagga mussels, are small organisms that could have huge impacts for Wyoming's waters, boaters, and anglers.They can ruin fisheries, clog cooling systems in motorboats, foul hulls, and ruin equipment. Anyone who uses water or recreates on water will be impacted.

There are several regulations in place to protect Wyoming’s resources. All boaters should be aware of these regulations. Any watercraft transported into Wyoming from March 1 through November 30 must undergo a mandatory inspection by an authorized inspector prior to launching.

“Please remember that if you pass an open watercraft check station on your route of travel, you are still required to stop. Our staff will quickly verify your seal is valid and send you on your way. In addition, local companies who cater to watercraft users can become certified to inspect watercraft through this training and then can provide and charge customers for these services.” -Wes Gordon Green River AIS Specialist

  • Any watercraft that has been in a water infested with zebra/quagga mussels within the last 30 days, is required to undergo a mandatory inspection by an authorized inspector prior to launching during ALL months of the year.
  • All watercraft must stop at any open watercraft check station on their route of travel, even if not intending to launch in Wyoming.
  • Any person transporting a watercraft by land from out-of-state who did not encounter an aquatic invasive species check station prior to reaching a water of the state may launch without further inspection if the watercraft has a properly affixed seal and is accompanied by a valid seal receipt during transit.
  • The person transporting the watercraft may remove the seal immediately prior to launching on the destination water and must retain the seal and valid seal receipt while on the water.
  • All visible vegetation must be removed from a watercraft/trailer once it leaves the water. Boaters must drain all water from watercraft, including all compartments, after leaving a water.

WGFD Southwest Aquatic Invasive Species (AIS) Specialist Wes Gordon inspects a lot of boats! Every state with AIS, or with neighboring states that do have AIS, are working really hard to keep invasive species like zebra and quagga mussels out of their waters. They cannot do that without your help! Clean, Drain and Dry your watercraft after every use.


 

 



Southwest Aquatic Invasive Species Coordinator Wes Gordon conducts a water quality sample on Flaming Gorge Reservoir. The sample will be sent to a laboratory to check for the presence of zebra or quagga mussel veligers.
