Please check this information before you transport your watercraft into Wyoming as this information will be updated regularly. Following is detailed information and a map of inspection facilities including locations, dates of operation, and hours of operation.
• 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 person transporting a watercraft who did not encounter a mandatory 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 applied by an authorized inspector 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.
