Shasta Division consists of a pair of large dams on the Sacramento River north of the city of Redding.
The Shasta Dam is the primary water storage and power generating facility of the CVP.
It impounds the Sacramento River to form Shasta Lake, which can store over 4,500,000 acre feet (5,600,000 dam³) of water, and can generate 680 MW of power.
Shasta Dam functions to regulate the flow of the Sacramento River so that downstream diversion dams and canals can capture the flow of the river more efficiently, and to prevent flooding in the Sacramento-San Joaquin Delta where many water pump facilities for San Joaquin Valley aqueducts are located.
The Keswick Dam functions as an afterbay (regulating reservoir) for the Shasta Dam, also generating power.

The Sacramento Canals Division of the CVP takes water from the Sacramento River much farther downstream of the Shasta and Keswick Dams.
Diversion dams, pumping plants, and aqueducts provide municipal water supply as well as irrigation of about 100,000 acres (4,000,000 dam²).
The Red Bluff Diversion Dam diverts part of the Sacramento River into the 110-mile (180 km) Tehama-Colusa Canal, the 21-mile (34 km) Corning Canal and a small reservoir formed by Funks Dam.
 Six pump plants take water from the canal and feed it to the Colusa County water distribution grid.
