Fontenelle Creek Campground is the developed site with organized campsites, restrooms, and running water. You pay a camping fee there. Three primitive campsites sit below the dam and are free to use. The 56-mile shoreline gives you boat access and stream fishing on the Green River both above and below the reservoir. Rainbow, brown, and cutthroat trout live in the water. Recreation use stays light year-round, so crowds are rare.

The Bureau of Reclamation manages the dam and reservoir under agreement with the BLM. Boat launching is free. Primitive camping and picnicking carry no charge. You should call ahead to confirm current conditions and any seasonal restrictions. The BOR operates the powerplant and manages water releases that affect downstream flows and fishing.

Access can be rough in winter and spring. Snow and mud close some roads seasonally. You need to check before driving the full distance from town. The nearest services are in Kemmerer or La Barge, both small towns with limited options.

Call the BLM at 307-352-0256 or 307-828-4500 before you go.
