The Sustainable Groundwater Management Act (SGMA) mandates that local agencies establish locally-controlled groundwater sustainability agencies (GSAs) for managing groundwater resources. SGMA defines a local agency as “a local public agency that has water supply, water management, or land use responsibilities within a groundwater basin.” Although public agencies must implement the provisions of SGMA, the governance of the GSA is not limited to public agencies.
The process of forming a GSA for the Upper Ventura River Groundwater Basin was initiated by a collaboration of five agencies that have an interest in the basin: Ventura River Water District, Meiners Oaks Water District, City of Ventura (Ventura Water), Casitas Municipal Water District, and the County of Ventura. These agencies, now collectively called the Formation Committee, are described below.
