May 28, 2025 - SACRAMENTO, Calif. – Continuing to focus on maximizing California’s water supplies, the Bureau of Reclamation is increasing the water supply allocations for Central Valley Project contractors south of the Sacramento-San Joaquin Bay-Delta. 

While all north-of-Delta Central Valley Project contractors are currently at 100% of their supplies, south-of-Delta irrigation water service and repayment contractors are increased to 55% from 50%, and municipal and industrial water service and repayment contractors are increased to 80% from 75% of their historical use, or public health and safety needs, whichever is greater.

“As California’s primary precipitation season concludes, we now have greater certainty about water availability for the remainder of the water year, said Acting Regional Director Adam Nickels. “This allows us to responsibly adjust Central Valley Project allocations to better meet the needs of our water users while continuing to support environmental requirements.”

All other Central Valley Project contract allocations remain the same per the April 28 water supply update. Initial Central Valley Project contract allocations were announced on Feb. 25.

The adjustment also reinforces Reclamation’s commitment to achieving the objectives outlined in Executive Order 14181, which seeks to maximize water supplies within the Central Valley Project.

As the water year progresses, changes in hydrology, actions that impact operations, and opportunities to deliver additional water will influence future allocations. Water supply updates and past year’s allocations are posted on Reclamation’s website.
