Lake Oroville in Butte County, the principal SWP reservoir, is at 36 percent of its 3.5 million acre-foot capacity (55 percent of the historical average for the date). 

Shasta Lake north of Redding - California’s and the federal Central Valley Project’s (CVP) largest reservoir - is at 36 percent of its 4.5 million acre-foot capacity (54 percent average to date). 

The San Luis Reservoir, a critical south-of-Delta reservoir for both the SWP and CVP, is at 30 percent of its two-million-acre-foot capacity (39 percent of average for the date).

Never before in the 54-year history of the State Water Project has DWR announced a zero allocation to all 29 public water agencies which buy from the SWP.

These deliveries help supply water to 25 million Californians and roughly 750,000 acres of irrigated farmland. 

Deliveries to senior water rights holders in the Sacramento Valley - all agricultural irrigation districts - were last cut in 1992.

The only previous State Water Project zero percent allocation was in 1991 for agriculture, but cities received a 30 percent allocation.

“Carryover” water stored by local agencies and water transferred from willing sellers to buyers in critically short areas still will be delivered, as will emergency supplies for drinking, sanitation, and fire protection.
