Water Supply

Annual Water Use and Supply

Unlike water agencies with more abundant supplies, Westlands must allocate (ration) water to its farmers, even in the wettest years. The District’s primary annual contract entitlements, plus reassignments contracts for a full entitlement, from the Central Valley Project (Project) total 1,193,000 acre-feet. The annual safe yield of the confined underground aquifer adds another 135,000 to 200,000 acre-feet. Thus, the total water available is about 215,000 acre-feet (15 percent) short of the 1,500,000 acre-feet required to irrigate the entire District.
