DWR Releases GSP Determinations for 10 Non-Critically Overdrafted Basins

The California Department of Water Resources (DWR) today released assessments of groundwater sustainability plans (GSPs) developed by local agencies to meet the requirements of the Sustainable Groundwater Management Act (SGMA).

Today’s release includes the approval of ten GSPs for the following basins: East Bay Plain in Alameda and Contra Costa Counties, East Contra Costa in Contra Costa County, North San Benito in San Benito and Santa Clara Counties, Ukiah Valley in Mendocino County, Sierra Valley in Plumas and Sierra Counties, North American in Placer, Sacramento, and Sutter Counties, South American in Sacramento County, Butte in Butte, Colusa, Glenn and Sutter Counties, Vina in Butte County, and Wyandotte Creek in Butte County.

The assessments can be viewed on the SGMA Portal. These plans are approved with recommended corrective actions that the groundwater sustainability agencies (GSAs) will need to address in their next plan update, due in January 2027. DWR’s approval of a GSP identifies that the plan substantially complies with the GSP Regulations and SGMA law, relying upon the best available science and information and whether implementation of the plan is likely to achieve the basin’s sustainability goal over the 20-year planning horizon of SGMA.

To provide additional information on these GSP assessments, DWR has prepared a press release providing an overview of these assessments and has a GSP Evaluation fact sheet summarizing SGMA’s determination pathways for GSPs. SGMA lays out a process for continuous improvement, gathering information to fill data gaps, updating plans, carrying out projects and actions, and promoting science-based adaption.

DWR encourages all SGMA interested parties to review the assessments, and related materials, accessible on our GSP webpage. For any SGMA-related questions, please email DWR at: sgmps@water.ca.gov.
