Voluntary Water Sharing Program

Since April 2021, a diverse group of stakeholders in the Russian River watershed have met to develop a Voluntary Water Sharing Program for the Upper Russian River. The program will provide water users in the Russian River watershed an alternative to curtailment of their water diversion and use. Participants will enroll in the program by reviewing and signing an agreement, a draft of which is available for review and input. The State Water Board is hosting this website to provide a means for making materials available to interested water right holders and the public.

November 3, 2022 - Russian River Voluntary Sharing Program Survey

To improve upon WSP implementation for future years, the Russian River Steering Committee asks interested parties to complete a survey describing their experience involving the program. The survey will be discussed further at the November 7, 2022 meeting. All answers will be aggregated to inform the Steering Committee's “2022 Lesson's Learned,” as well as the future outlook for this Program. Deadline to Submit: November 23, 2022.

September 30, 2022 - Continued Program Suspension

Exceptions to curtailment under the Russian River Voluntary Water Sharing Program (WSP) remain temporarily suspended for October. Please note that since the WSP was temporarily suspended for the month of September, September water use reporting for WSP diversions is not required. The Division will continue to monitor conditions and assess whether curtailment exceptions for WSP participants could resume. Additional discussion will take place at the next monthly WSP virtual meeting on November 7, 2022, via Zoom. Please visit the Monthly Meetings section below for more details.

August 5, 2022 - Temporary Program Suspension

The Federal Energy Regulatory Commission issued an order to PG&E Company on July 27, 2022, approving a variance that substantially reduces flows from the Potter Valley Project to the Russian River Watershed. Based on current conditions and analyses described in Exhibit B to the Russian River WSP, there is insufficient supply available for sharing. The Division has determined that continued diversions under the WSP threaten to adversely affect the availability of water for non-participants. Within 14 days of this announcement, WSP participants must reduce or cease diversions in accordance with the curtailment status for their right, as identified on the Curtailment Status List posted on the Russian River Drought Response webpage. The Division will continue to monitor conditions and assess whether curtailment exceptions for WSP participants could resume.
