For Release: May 21, 2003
Reclamation today announced a 5-percent increase in water supply to agricultural and Municipal and Industrial (M&I) contractors south of the Delta from the Federal Central Valley Project (CVP) bringing the allocation to agricultural contractors to 70 percent and M&I to 95 percent. Reclamation's official allocation uses the 90-percent exceedence forecast, which is based on a below normal year classification in the May 2003 runoff information prepared by the California Department of Water Resources (DWR).

At this time, the CVP Cross Valley Canal Contractors will receive an in-delta water supply of 70 percent. This water supply is dependent upon the availability of adequate capacity to convey the water at the State Water Project Banks Pumping Plant.
Based on the May 1, 2003, 90-percent exceedence forecast, the CVP East Side Division contractors (Stanislaus River) would have a water supply allocation of 2,000 acre-feet or 1 percent of their contract amount. This runoff forecast was updated on May 15, 2003, and the CVP East Side Division contractors will have a water supply allocation of 10,000 acre-feet or 6 percent of their contract amount. (In the April forecast, 0 percent was available.) The CVP East Side Division contractor water supply allocation is based on New Melones Reservoir storage and the inflow to New Melones Reservoir.
In cooperation with CALFED agencies, Reclamation has developed and implemented an operations plan for 2003 which supports water supply reliability and fishery protections and restoration needs. The current plan employs water augmentation tools reflected in the forecast including use of the Environmental Water Account assets to satisfy potential late spring export curtailments at the CVP Tracy Pumping Plant and efficient utilization of San Luis Reservoir storage.
The Friant Division deliveries for Water Year 2003 are projected to be 800,000 acre-feet or 53 percent of the historic water supply of 1.5 million acre-feet. The allocation for Friant Division contractors will be 100 percent of Class 1 water and 0 (zero) percent of Class 2 water. However, Reclamation will make available for Class 2 contractors approximately 240,000 acre-feet of Class 2 water under the "Uncontrolled Season" part of their contract. This allows the Class 2 Contractors to take water during this period which runs from April 22 to May 22, 2003. Through May 20, 2003, precipitation in the San Joaquin River watershed was 40.66 inches compared to 35.04 inches at this time last year.)
