About the Sustainable Groundwater Management Act (SGMA)
In September 2014, Governor Brown signed into law the Sustainable Groundwater Management Act (SGMA), which provides a framework to regulate groundwater for the first time in California’s history. SGMA became effective January 1, 2015. The intent of the law is to strengthen local groundwater management of basins most critical to the state’s water needs with an understanding that groundwater is most effectively managed at the local level.
SGMA requires basins to be sustainably managed by local public agencies (e.g., counties, cities, and water agencies) who become groundwater sustainability agencies, or GSAs. The primary purpose of the GSAs is to develop and implement a Groundwater Sustainability Plan (GSP) to achieve long-term groundwater sustainability.
Comprehensive stakeholder involvement is critical to sustainable groundwater management, and SGMA requires GSAs to involve stakeholders and interested parties in implementation of SGMA.

In San Diego County, the State has designated four of the county’s basins as medium-priority and subject to SGMA: Borrego Valley, San Diego River Valley, San Luis Rey Valley and San Pasqual Valley.
