Municipal and Industrial supply is based on historical deliveries. *The allocation percentage for both the 50 and 90 percent forecasts is the same. This is due to Water Quality Control Plan actions and actions for protection of endangered species. In the 90-percent exceedence forecast, there is no water supply allocation for the CVP East Side Division contractors (Stanislaus River). In the 50-percent exceedence forecast, the allocation is projected to be approximately 2 percent of the contracted amount.
The Friant Division deliveries for Water Year 2003 are projected to be 720,000 acre-feet, or 48 percent of the historic water supply of 1.5 million acre-feet. The allocation for Friant Division contractors will be 90 percent of Class 1 water and 0 (zero) percent of Class 2 water. The projected Friant Division delivery of 720,000 acre-feet is based on the DWR 90-percent exceedence forecast. The 2003 precipitation season is about 77 percent completed. Through March 16, 2003, precipitation in the San Joaquin River watershed was 28.43 inches compared to 30.49 inches this time last year.
Throughout the precipitation season, updated information will be provided as conditions warrant.
