Groundwater Sustainability Plan

On January 18, 2024, the California Department of Water Resources (DWR) approved the Solano Subbasin Groundwater Sustainability Plan (GSP). Read DWR’s statement of findings regarding the approval of the Solano Subbasin GSP under SGMA.

The GSP provides a detailed roadmap for the Solano Subbasin to maintain long-term groundwater sustainability, and went into effect when it was submitted to DWR on January 31, 2022. Opportunities for comments, including a public meeting, were posted on the Solano Subbasin GSP website. The GSP was the product of significant collaboration amongst various water management entities in the Subbasin, including the five Groundwater Sustainability Agencies comprising the Solano Subbasin GSA Collaborative, who worked together to fulfill the requirements of the Sustainable Groundwater Management Act (SGMA).
