Do I need a decal to boat in waters shared by other states, such as Flaming Gorge, Big Horn Lake, Palisades Reservoir, and the North Platte River?
Yes, once you enter the waters of Wyoming you will need a decal and all applicable AIS rules and regulations will apply. For instance, if you launch your watercraft in another state and boat into Wyoming, you will need a Wyoming Aquatic Invasive Species decal once you enter the Wyoming portion of that water.
