After reviewing the manual snow survey data from the California Department of Water Resources that was provided the week of April 8, the Bureau of Reclamation has determined that due to persistent dry conditions an additional adjustment to the Friant Division allocation is necessary.

In consultation with the Friant Division Contractors and in consideration of the San Joaquin River Restoration Program release schedule, the Friant Division Class 1 water supply allocation is decreased from 55 percent to 50 percent. Class 2 water remains at 0 percent.

Currently, precipitation in the Upper San Joaquin River watershed at Huntington Lake is about 19.7 inches, which is about 53 percent of average for this time of year. Additionally, accumulated natural river flow to date for WY 2013 for the Upper San Joaquin Basin is about 400,000 acre-feet which is about 22 percent of the total water year average of 1.8 million acre-feet, and about 65 percent of the historical average for this date.

Water supply updates will be made as appropriate and will be posted on http://www.usbr.gov/mp/pa/water.
