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 and FERC Licensing Update

On May 13th the five NOI partners (Mendocino County Inland Water and Power Commission, Sonoma Water,California Trout, the County of Humboldt and the Round Valley Indian Tribe) submitted the required feasibility study report for the Potter Valley Project (PVP) to the Federal Energy Regulatory Commission (FERC). This was the next step towards Relicensing the PVP. There are several issues that concern MCFB in the feasibility report, number one being the possibility of removing Scott Dam, and thereby Lake Pillsbury and essentially eliminating summer water availability to the Eel River, the PVP and the Russian River. Lake Pillsbury captures water during the winter months which is then released during the summer to provide water for fish in the Eel River. A portion of this water is also funneled through the Potter Valley Project and becomes the head waters of the Russian River. This water is stored in Lake Mendocino and dolled out throughout the summer to hundreds of thousands of people in Mendocino, Sonoma, and Marin Counties. June 28th was the deadline to submit comments on the Feasibility Study Report. You can see the comment letter submitted by MCFB on our website. The next step will be for the NOI partners to complete a series of studies to determine how to move forward with the relicensing. For more information on the relicensing project and how Farm Bureau is continuing to work towards securing our water supply, go to our website and check out the Potter Valley Project page under the advocacy tab.

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)

Map of 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.

“In my opinion, the benefits realized from the small amount of money we pay for the membership, by far outweighs the cost. If I had to go to a Water Rights Specialist alone, I would be talking about hundreds if not thousands of dollars.”Sandra Hognestadmember since 1995
