Wind

The Tribes of the Wind River Indian Reservation do not allow private boating through Wind River Canyon without Tribal Council approval, even with a Reservation fishing license (although fishing from the bank is allowed). Contact Wind River Fish and Game with questions:

Rafting is only allowed on this stretch through guided trips with Wind River Canyon Whitewater (WRCW) located in Thermopolis, WY. Safety kayaking for WRCW or obtaining permission from the Tribes is the only way to paddle this stretch via kayak. The two legal stretches of the Wind River below Boysen Reservoir are from just below Boysen Dam to the Lower Wind River Campground within the State Park (1.5 miles of river), or below 'Wedding of the Waters,' at the mouth of the canyon, through Thermopolis to several different take out locations. These stretches are mostly flat water, but some hazards exist, like strainers and bridge pylons, that warrant some experience, particularly at higher flows.

The proper gauge for Wind River Canyon is through the U.S. Bureau of Reclamation, Hydromet or reservoir data pages.
