Upper Stillwater Reservoir is a large high mountain reservoir on the south slope of the High Uintas in Duchesne County, Utah. The reservoir is part of the Central Utah Project.

The reservoir was created in 1987 by the construction of a concrete gravity dam (Upper Stillwater Dam). The architecture of the rolled concrete dam is an attraction for engineers.

The reservoir elevation is 8,176 ft, and the mean depth is 103.5 ft. Available fish species include rainbow, brown, and brook trout.

The watershed is primarily the Uinta Mountains, the watershed high point being Ostler Peak (12,717 ft). It is estimated that twice or more the capacity of the reservoir is diverted towards the Wasatch Front annually. The primary use of the water is for irrigation.[1]

Recreation

The area has one main campground, Rock Creek. The reservoir serves as a popular trailhead into the High Uintas Wilderness Area with the boundary only one mile north of the dam near the high water line for the reservoir. Recreation management is under the jurisdiction of the U.S. Forest Service, Ashley National Forest. The managed recreation season is from June through September with high use on holidays and weekends. Boating, swimming, camping, fishing, hiking, horseback riding, picnicking, recreational vehicle driving, wildlife viewing, and winter sports are all popular activities.[2]
