(1) The allocation shown in the table for wildlife refuges applies to Level 2 water supplies. A full refuge water supply (including Level 2 and incremental Level 4 water) is 555,515 acre-feet. Level 2 is 422,251 acre-feet, which accounts for approximately three-fourths of annual refuge needs.

(2) The allocation for water rights contractors are based upon pre-CVP held water rights. Specific to contractual supply for Exchange Contractors and San Joaquin River Settlement Contractors, Reclamation will meet the critical year demands for the months of April through October and will work throughout the summer to explore the ability to provide additional water as called for under these contracts. For the Exchange Contractors, these demands will be satisfied by both Delta and San Joaquin River sources for a total of 529,000 acre-feet.

Final 2013 Friant Division Water Allocation

FRESNO, Calif. – Due to better than expected hydrologic conditions through the latter part of June and first 12 days of July, the Bureau of Reclamation has determined that it will further increase the Central Valley Project’s Friant Division water supply allocation.

In consultation with Friant Division contractors, the Friant Division Class 1 water supply allocation is being increased from 55 percent to 62 percent. On June 13, Reclamation announced an increase from 50 percent to 55 percent. Class 2 water remains at 0 percent. (The first 800,000 acre-feet of water supply is considered Class 1 and the next 1.4 million acre-feet is considered Class 2). The latest information on upstream operations, canal demand schedules, and the San Joaquin River Restoration Program flow release schedule have also been incorporated into this allocation update.

Currently, precipitation in the Upper San Joaquin River watershed at Huntington Lake is about 20.5 inches, which is about 49 percent of average for this time of year. Additionally, accumulated natural river flow to date for Water Year 2013 for the Upper San Joaquin Basin is about 822,000 acre-feet, which is about 50 percent of the historical average for this date, and about 46 percent of the total Water Year average of 1.8 million acre-feet.

Water supply updates will be made as appropriate and will be posted on http://www.usbr.gov/mp/pa/water. For additional information, please contact the Public Affairs Office at 916-978-5100 (TTY 916-978-5608) or email mppublicaffairs@usbr.gov.
