Keswick Dam is a concrete gravity dam on the Sacramento River about 2 miles (3.2 km) northwest of Redding, California. Part of the U.S. Bureau of Reclamation's Central Valley Project, the dam is 157 feet (48 m) high and impounds the Keswick Reservoir, which has a capacity of 23,800 acre⋅ft (29,400,000 m³). The dam's power plant has three turbines with a generating capacity of 117 megawatts (MW), 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.

The electrical substation at Keswick Dam distributes power from the Keswick power plant, the power plants at Trinity Dam and Lewiston Dam, the Judge Francis Carr Power plant near Whiskeytown Lake, and the Spring Creek Power plant, which is located just northwest of Keswick Dam.
