Shasta Dam, which was completed in 1945 on the upper Sacramento River northwest of Redding, is the second-largest reservoir run by the Bureau of Reclamation in the country, behind Grand Coulee Dam in Washington.
Description: Located 9 miles downriver from Shasta Dam. The nearest highway is 299 West.Keswick Dam and reservoir are features of the Central Valley Project-Shasta/Tinity River Divisions. The dam creates a 23,800-acre-foot afterbay for Shasta Lake. Keswick Dam has migratory fish-trapping facilities in conjunction with the Coleman Fish Hatchery, 25 miles downstream on Battle Creek. The salmon and steelhead are trapped as they reach the dam, then transported to the fish hatchery for milking. Keswick Reservoir does not have salmon or steelhead; it does have a healthy population of wild trout, including German browns and rainbows. The majority of the fish are native.
