Keswick Dam is a 157-foot-high concrete gravity dam, with a crest length of 1,046 feet, constructed 9 miles downstream from Shasta Dam on the Sacramento River. Keswick Dam acts as an afterbay dam controlling river fluctuations from the Shasta Powerplant. Water released from Shasta Dam downstream to the Keswick Reservoir is stored for release through Keswick Dam and Powerplant. With steady releases from Keswick Dam, managers are able to regulate the flows of the Sacramento River downstream. Keswick Power Plant has three generators with a rated capacity of 105 megawatts.
