Groundwater Sustainability Agencies
The Sustainable Groundwater Management Act (SGMA) established a new structure for managing California’s groundwater resources at the local level by local agencies. SGMA required Groundwater Sustainability Agencies (GSAs) to form in the State’s high and medium priority basins and subbasins by July 1, 2017.
The legislative intent of SGMA is to recognize and preserve the authority of cities and counties to manage groundwater according to their existing powers. As a result, local governments play an important land use and water management role in California and should be involved in GSA formation and Groundwater Sustainability Plan (GSP) implementation. These locally controlled GSAs have the authority and responsibility to sustainably manage their respective groundwater basins.
Agency Roles
SGMA assigns different roles to DWR, the State Water Resources Control Board, local agencies and counties related to GSA formation.
- In the event that there is an area within a high- or medium-priority basin that is not within the management area of a GSA, the county within which that unmanaged area lies will be presumed to be the GSA for that area. (Water Code § 10724(a))
- A county shall provide notification to DWR of its intent to manage the unmanaged area pursuant to Water Code §10723.8 unless the county notifies DWR in writing that it will not be the GSA for the area. (Water Code § 10724(b))
