Sustainable Groundwater Management Act

The Sustainable Groundwater Management Act (SGMA), a collection of three bills (AB 1739, SB 1168, and SB 1319), provides local agencies with the framework necessary to sustainably manage medium and high priority groundwater basins, as described by the act, with the goal to bring the basins into balance in 20 years.

SGMA Background and Objectives

Department of Water Resources (DWR) identifies groundwater basins in California that are subject to the Sustainable Groundwater Management Act (Act). The Act provides local agencies or counties ability to establish a Groundwater Sustainability Agency (GSA) and develop and implement a Groundwater Sustainability Plan (GSP) that considers all beneficial uses and users of groundwater in the basin. High and medium priority basins must develop GSPs. Adjudicated areas in basins are not required to form a GSA.

The Act provides for a tailored approach to planning, and puts responsibilities at the local level for managing a basin’s groundwater resources. Minimum standards are established for sustainable groundwater management by improving coordination between land use and groundwater planning.

Timeline for Steps to Sustainability


Impact to the County (Unincorporated Area and Waterworks Districts)

The Waterworks Districts and the Department of Regional Planning, which is assigned to represent unincorporated areas, will be required to form GSAs by entering into MOUs with other involved water agencies in each affected basin by June 30, 2017.

GSA Formation

SGMA requires local agencies to establish a new governance structure, known as a GSA, prior to developing groundwater sustainability plans for groundwater basins or sub-basins that are designated as medium or high priority. Two regions that LACWD serves as part of the Antelope Valley Basin is East Acton and Leona Valley which are designated at medium/high priority. LACWD has submitted GSA applications for these two regions and the notices have been made public. To view the GSA notice for either region, click on the links below.
