Russian River Drought Response
Governor Newsom declared a drought emergency in Sonoma and Mendocino Counties largely due to abnormally dry conditions in the Russian River watershed. The watershed is home to 360,000 people and provides water for municipal and private wells, agriculture, wineries and recreation. As the region’s drought situation worsens, local and state governments and community members are collaborating to address water shortages.
Below are links to important information regarding drought activities in the Russian River.
March 29, 2023 - Curtailment Orders Rescinded for the Russian River Watershed
The Deputy Director for the Division of Water Rights has rescinded all curtailment orders currently implementing the emergency regulation in the Russian River watershed. Water right holders are no longer required to check their individual curtailment status and riparian water budgets or to complete reporting for human health and safety exceptions. For more information, please visit the Russian River Watershed Curtailment Status List section below.

Curtailment Status Analysis
The Curtailment Status analysis utilizes a combination of reported diversion and use, forecasted flow data, and hydrologic models to determine water availability in the Russian River. Provided below is a summary of the methodology as well as supply and demand data used.
The Drought Water Rights Allocation Tool (DWRAT) was used to allocate available supply amongst water right holders based on their respective water right priority and water demands. The Russian River watershed was delineated into sub-basins, which allows a finer spatial resolution of assessing the water supply available for diversion. The DWRAT output files include information about available basin flows, basin demands, curtailments, and shortages by user and by basin.
The code-base and input data for the Lower Russian River modeling are available in a GitHub repository as part of the California Water Board Data Center. The Python version of DWRAT can be accessed via the following link: https://github.com/CAWaterBoardDataCenter/DWRAT. The DWRAT repository also contains archived scripts for previous months" curtailment status analysis. Please direct specific questions regarding DWRAT or the programming code to Daron Pedroja at email@example.com.

The Division of Water Rights has temporarily suspending all curtailments in the Russian River Watershed. Based on available forecasts, the Division expects that the temporary suspensions may last through November 30, 2021. Curtailments may resume in December unless additional precipitation arrives beyond what is currently forecasted and could resume earlier if actual precipitation is less than forecasts expect.
Curtailment Response Forms
On Friday, August 20, 2021, the Division of Water Rights held an informational Compliance Assistance Workshop to provide guidance and further information to diverters responding to curtailment orders for the Upper and Lower Russian River Watershed. A video recording of the workshop and Q&A session is available here.
Curtailment responses should be submitted at the following web address https://public.waterboards.ca.gov/WRInfo. Please note that the password to log in to the website is the same as your RMS reporting password. The username is your water right. There are four separate forms. You can click on the links below to view an example of each form.
If you have previously filed an exception to curtailment under the 2021 Emergency Regulation, it is not required that you file again under the 2022 Emergency Regulation. Your previous exception will be honored. If anything has changed regarding your exception or if you no longer require an exception, please contact the Russian River Drought Response Team by email at RussianRiverDrought@waterboards.ca.gov or by phone at (916) 341-5318.
Russian River Human Health and Safety Certification Form
The Russian River Health and Safety Certification Form is only for right holders continuing diversion for minimum human health and safety as defined in the emergency regulation.

- Health and Safety Certification Form Tutorial Video
Russian River Health and Safety Petition Form
The Russian River Health and Safety Petition Form is for right holders petitioning to divert greater 55 gallons for minimum human health and safety.
Russian River Non-Consumptive Use Exception Form
The Russian River Non-Consumptive Use Exception Form is for right holders continuing to divert for non-consumptive uses.
Russian River Diversion Reporting Form
The Russian River Diversion Reporting Form is for right holders continuing to divert to report their monthly diversion. Each month by the 10th all water right holders continuing to divert under a exception from the Russian River curtailment must fill out this form. The Deputy Director may select additional reporting requirements on a case by case basis so some diverters may see additional or modified questions.

Russian River 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. For more information, please visit the Voluntary Water Sharing Program webpage.

Curtailment Order Rescission
Effective March 29, 2023, the Deputy Director for the Division of Water Rights (Division) has rescinded all curtailment orders currently implementing the drought emergency regulation in the Russian River watershed. Following the Governor’s recent Executive Order (N-5-23) and in consideration of reservoir storage conditions and continued precipitation throughout the region, curtailment orders are no longer needed in the Russian River Watershed.
Executive Order N-5-23 terminates the provisions of the April 2021 State of Emergency Proclamation that authorized the State Water Board to adopt an emergency regulation for the Russian River watershed. However, the EO does not terminate the current regulation itself, which will remain in effect until its expiration on June 1, 2023.
As a result of rescinding the curtailment orders, water right holders will no longer be subject to the curtailment requirements under the emergency regulation. These include checking curtailment status, restrictions on riparian diversions, and reporting requirements for human health and safety exceptions. Please note that this rescission will not eliminate ongoing or pending enforcement actions and related settlements.
