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.
The Oroville Dam also manages an incredible amount of water; its full capacity measures 3,537,577 acre-feet, and it boasts a drainage area of 3,607 square miles. Significantly shorter than the Oroville Dam, the New Bullards Bar Dam in Yuba County was completed in 1970 and stands an impressive 635 feet tall. Built across the North Yuba River, the variable radius arch concrete structure provides a reservoir capacity of 969,900 acre-feet and a drainage area of 481 square miles. Like the Oroville Dam, New Bullards Bar generates power, drinking water, flood control and irrigation for the surrounding communities.
