Part of the U.S. Bureau of Reclamation's Central Valley Project, the dam is 157 feet high and impounds the Keswick Reservoir, which has a capacity of 23,800 acre⋅ft. The dam's power plant has three turbines with a generating capacity of 117 megawatts, which, in 1992, was uprated from its original 75 MW. The dam and reservoir serve as an afterbay to regulate peaking power releases from the Shasta Dam upstream.
