Shasta Dam and Reservoir Enlargement Project
Shasta Lake, located in northern California, is the largest reservoir in Reclamation's Central Valley Project.
Reclamation's feasibility study and reports have evaluated potential effects of an array of alternative plans to determine the technical, environmental, economic and ﬁnancial feasibility of enlarging the existing Shasta Reservoir as a part of the Shasta Lake Water Resources Investigation.
Enlarging the reservoir would improve water supply reliability, reduce ﬂood damages, and improve water temperatures in the Sacramento River below the dam for anadromous ﬁsh survival.
