APPROVAL of the Temporary Urgency Change Petition (TUCP) on the Russian River
On December 27th, 2023, the State Water Resources Control Board issued the Order approving Sonoma Water’s Temporary Urgency Change Petition (filed 10/12/2023) on water-right Permits 12947A, 12949, 12950, and 16596 (Applications 12919A, 15736, 15737, and 19351) to modify the hydrologic index used to set minimum instream flows in the Upper Russian River, Lower Russian River, and Dry Creek. Under the Order, the water supply conditions in the Russian River are established based on storage thresholds in Lake Mendocino instead of cumulative inflow into Lake Pillsbury. For additional information visit Sonoma Water’s TUCP webpage and TUCP archive.
Eel Russian Project Authority – First Meeting Scheduled for Jan 31st 3 PM
The Eel-Russian Project Authority (ERPA) is a joint powers authority formed by a joint exercise of powers agreement between the County of Sonoma, Sonoma County Water Agency (Sonoma Water), and the Mendocino County Inland Water and Power Commission.
ERPA will have the power to negotiate with the Pacific Gas and Electric Company (PG&E) as the utility moves ahead with plans to surrender operations of the Potter Valley Hydroelectric Project and to decommission the Scott and Cape Horn dams on the Eel River. The new authority will also have the legal capacity to own, construct and operate a new water diversion facility near the Cape Horn Dam.
A new website has been created to host information for the Eel-Russian Project Authority. The website can be viewed at www.eelrussianauthority.org. Authority agendas, minutes and presentations will be posted on this website. Please note that the first Authority meeting is January 31 at 3pm at the Sonoma County Board of Supervisors Chambers located at 575 Administration Drive, Room 102A, Santa Rosa, CA 95403. A virtual Zoom option to listen to the meeting will be made available. Please see the website for more information.
Supply and Demand Assessment (SDA) by the SWRCB in the Russian River
The SDA Unit has continued to work on the models and tools developed for the Russian River Watershed during the State Water Board's 2021-2022 Regional Drought Response. These tools provided the necessary information for the Division of Water Rights (Division) to assess water availability and issue water right curtailments to ensure adequate, minimal water supplies for critical purposes under the emergency regulation. Visit the Water Rights Demand Data Analysis Methodology webpage to learn more and try out the tool.
The Division used a water allocation tool adopted from the UC Davis Drought Water Rights Allocation Tool (DWRAT) to allocate available supply amongst water right holders based on their respective water right priority and water demands.
