Sustainable Groundwater Management Act (SGMA) Basin Prioritization

Published by California Department of Water Resources | State of California | Metadata Last Checked: July 29, 2025 | Last Modified: 2022-07-26T23:39:59.473881
The following data and resources were used for the SGMA Basin Prioritization of California’s 515 groundwater basins and subbasins. The Department of Water Resources is mandated by California Water Code Section 10933(b) to prioritize each basin based on eight components. For more information about how the data was analyzed for Basin Prioritization please see [Sustainable Groundwater Management Act Basin Prioritization - Process and Results Document](https://data.cnra.ca.gov/dataset/13ebd2d3-4e62-4fee-9342-d7c3ef3e0079/resource/ffafd27b-5e7e-4db3-b846-e7b3cb5c614c/download/sgma_bp_process_document.pdf). Additional questions or requests for information related any of the Basin Prioritization datasets should be directed to the Sustainable Groundwater Management Office at sgmps@water.ca.gov.
