From the State Water Resources Control Board:
State Water Resources Control Board (State Water Board or Board) staff have posted updated versions of the supporting documentation for the Water Unavailability Methodology for the Sacramento-San Joaquin Delta Watershed (Water Unavailability Methodology or methodology). The Water Unavailability Methodology is used to determine when curtailments of water right holders and claimants in the Delta watershed are necessary based on forecasted water supplies and estimated demands. These refinements reflect input received at the workshop held on November 9, 2022, regarding the proposed refined watershed analysis and Friant priority date adjustments. In addition, the refinements reflect public comment input received about the workshop topics and minor additional updates for consistency.
The updated resources are available on the Water Unavailability Methodology webpage.
For more information regarding drought in the Delta watershed, please visit the Delta Drought webpage. To view the curtailment status of a specific water right or claim in the Delta watershed, please check the Delta Watershed Curtailment Status List.
If you have any questions, you may send an email to Bay-Delta@waterboards.ca.gov or call the Delta Drought phone line at (916) 319-0960.
