Member Agencies
Under SGMA, Groundwater Sustainability Agencies (GSAs) are entities formed by local government agencies with land use authority or water supply or water management responsibilities. The Sonoma Valley GSA was created in 2017 when the participating agencies, listed below, entered into a Joint Exercise of Powers Agreement (JPA). The JPA spells out GSA Board membership, initial funding, voting and other governance issues. The GSA Board of Directors includes one representative from each member agency. Each member agency also has a representative on the Advisory Committee.

The County of Sonoma provide a full range of services to our community; the County plays a dual role to residents, providing municipal services such as law enforcement and fire protection to unincorporated areas and providing the day-to-day operation of state and federally mandated programs.
North Bay Water District
The North Bay Water District was established in 1963 by special public election with an intent to bring in irrigation water. The District covers 42.5 square miles (27,200 acres) of agricultural and public lands that extend from the Marin-Sonoma county line to the Sonoma-Napa county line along the shore of San Pablo Bay. When SGMA was enacted, Sonoma County Farm Bureau strongly backed the District to participate in the new GSAs as the voice of agriculture. The District’s current five-member board represents grape-growing, dairy, hay farming, and grazing in the area.
