The CVP has a significant amount of facilities for storing and transporting water on the west side of the San Joaquin Valley, in the foothills of the California Coast Ranges.
The West San Joaquin Division and San Luis Unit consist of several major facilities that are shared with the federal California State Water Project (SWP).
San Luis Dam (or B.F. Sisk Dam) is the largest storage facility, holding 2,000,000 acre feet (2,500,000 dam³) of water.

Although called an offstream storage reservoir by USBR, the reservoir floods part of the San Luis Creek valley.
San Luis Creek, however, is not the primary water source for the reservoir.
Downstream of San Luis Reservoir is O'Neill Forebay, which is intersected by the Delta-Mendota Canal, a separate CVP facility.
Water is pumped from the canal into the Forebay and uphill into San Luis Reservoir, which functions as an additional water source during dry periods.

Water released from San Luis and O'Neill reservoirs feeds into the San Luis Canal, the federally built section of the California Aqueduct, which carries both CVP and SWP water.
The San Luis Canal terminates at Kettleman City, where it connects with the state-built section of the California Aqueduct.
With a capacity of 13,100 cubic feet per second (370 m³/s), it is one of the largest irrigation canals in the United States.
The Coalinga or Pleasant Valley Canal branches off the San Luis Canal towards the Coalinga area.
A pair of separate dams, Los Baños Detention Dam and Little Panoche Detention Dam, provide flood control in the Los Baños area.
 The San Luis Drain was a separate project by USBR in an attempt to keep contaminated irrigation drainage water out of the San Joaquin River, emptying into Kesterson Reservoir where the water would evaporate or seep into the ground.
Because of environmental concerns, the system was never completed.

The CVP also operates a San Felipe Division to supply water to 63,500 acres (25,700 ha) of land in the Santa Clara Valley west of the Coast Ranges.
San Justo Dam stores water diverted from San Luis Reservoir through the Pacheco Tunnel and Hollister Conduit, which travel through the Diablo Range.
A separate canal, the Santa Clara Tunnel and Conduit, carries water to the Santa Clara Valley.
