It is our goal to share as much information as possible with the public about the Colorado River Compacts, continuing drought, and potential impacts to Wyoming.

The water in Uinta County is divided into two separate watersheds by the 'Three Sisters' or the 'Divide'. To the west, the Upper Bear River Watershed is part of the Great Salt Lake Basin Watershed. To the east, the Muddy, Black's Fork, and Henry's Fork Watersheds are part of the Green River Watershed, which is part of the larger Colorado River Basin Watershed.  

Uinta County landowners and producers that divert water off a tributary of the Green River, including but not limited to Henry's Fork, Smith's Fork, and Black's Fork, are affected by the Colorado River Compacts. Residents and recreationists are also impacted.
