Water is an important topic here in Mendocino County for farmers, ranchers, wildlife, residents and businesses. Farmers and ranchers in Mendocino County are very aware of the importance of a long-term, reliable water supply and good water quality for everyone. Mendocino County Farm Bureau works directly with farmers and ranchers in the various watersheds to consider critically important water issues. Farm Bureau’s Water Committee reaches out to collaborate with multiple stakeholder groups and seeks to build partnerships that allow us to do even more for our members.

Potter Valley Project Variance Request
On May 13, PG&E submitted a flow variance request for the Potter Valley Hydroelectric Project (Project) requesting a license diversion variance from the Federal Energy Regulatory Commission (FERC). The reason for the variance is stated to protect storage and to preserve the cold-water pool in Lake Pillsbury for fishery needs. The flow variance is asking for the approval to go to a critical drought year release to the East Fork Russian River of 5 CFS with the potential to increase to dry year release flow of 25 CFS depending on storage in Lake Pillsbury. The Project has been operating under normal year releases of 75 CFS since May 15th . Potter Valley Irrigation District will remain on demand-based scheduling for water contract releases. The variance, if approved, would have significant impacts on the Upper Russian River water supply, which will be further discussed below. MCFB submitted comments expressing concerns about the variance proposal, including the lack of engagement with Russian River stakeholders, the minimum pool level designation for Lake Pillsbury, and the use of “Block” water. The comment letter can be found on the MCFB website: https://www.mendofb.org/advocacy/potter-valley-project-licensing/

Water Diversion and Use Reporting
If you divert and use water from a surface water source such as a lake, creek, stream, or river, or you divert water from a subterranean stream that flows in a known and definite channel, California law requires you to report your diversion and use to the State Water Board, Division of Water Rights. Water use reports shall be filed on an annual basis and shall document diversions made during the prior calendar year. Reports for permits, licenses, registrations and certificates are due by April 1st. Statements of water diversion and use (riparian rights) or groundwater recordation are due by July 1st. All water right holders who have previously diverted or intend to divert more than 10 acre-feet per year (riparian and pre-1914 ), or are authorized to divert more than 10 acre-feet per year under a permit, license, or registration, are required to measure the water they divert.
The Sustainable Groundwater Management Act (SGMA)
In December 2014, the Department of Water Resources (DWR) released the ground water basin classifications to determine coverage under SGMA. For Mendocino County, the upper Russian River from the Tomki Road area in Redwood Valley to Knight Hill (north of Hopland) was classified as a medium priority ground water basin, the Ukiah Valley ground water basin # 1-52, and is subject to SGMA compliance. From July of 2016 until July of 2017, the Mendocino County Water Agency hosted public meetings to assist in the formation of the Groundwater Sustainability Agency (GSA) and Farm Bureau was at the table to ensure that agriculture was represented in the process. The GSA formation was the first step to work toward compliance and this was completed in June of 2017. The Ukiah Valley Basin Groundwater Sustainability Agency (UVBGSA) was created by a Joint Powers Agreement (JPA) and have been meeting regularly since 2017 to work toward the development of the groundwater sustainability plan (GSP) for the basin. The GSP will need to be finalized and submitted to DWR by 2022. For additional information, please see the links below.
