Sustainable Groundwater Management

Groundwater sustainability is the development and use of groundwater resources to meet current and future beneficial uses without causing unacceptable environmental or socioeconomic consequences (USGS Circular 1186). 

CA Dept of Water Resources: Sustainable Groundwater Management Act (SGMA) is intended to achieve groundwater basin sustainability goals over 20 years and requires GSAs to manage groundwater sustainably by avoiding locally defined undesirable results and considering all beneficial uses and users including drinking water users.


The Department of Water Resources published Alignment & Coordination: Water Shortage Planning for Rural Communities and Sustainable Groundwater Management in March of 2023. The Report identifies opportunities and encourages counties and groundwater sustainability agencies (GSAs) to align and coordinate their respective responsibilities for drought and water shortage planning efforts for rural communities under Senate Bill (SB) 552 and the long-term sustainability goals of groundwater basins under the Sustainable Groundwater Management Act (SGMA).
