Welcome to the Solano Subbasin Groundwater Sustainability Plan
The Sustainable Groundwater Management Act (SGMA) established a robust framework for the sustainable management of groundwater resources in California. SGMA requires Groundwater Sustainability Agencies (GSAs) to develop, implement, and enforce a Groundwater Sustainability Plan (GSP) for groundwater basins or subbasins that are medium or high priority. The Solano Subbasin is a medium priority subbasin, subject to SGMA.

About the Solano Collaborative
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 SGMA.

Frequently Asked Questions
What is a Groundwater Sustainability Plan (GSP)?
A Groundwater Sustainability Plan (GSP) is the state-mandated plan to sustainably manage groundwater. Each GSP will contain an assessment of each basin, measurable objectives that are specific, and quantifiable goals for the maintenance or improvement of specified groundwater conditions that have been included in an adopted Plan to achieve the sustainability goal for the basin. The GSP will also include any necessary monitoring, management, enforcement, and other requirements to achieve and/or maintain sustainability.
What does a Groundwater Sustainability Agency (GSA) do?
The primary purpose of a GSA under SGMA is to develop and implement a Groundwater Sustainability Plan (GSP) to achieve long-term groundwater sustainability. GSAs are empowered to utilize a number of new management tools to achieve the sustainability goal, such as: register and meter groundwater wells, mandate annual extraction and water level reports from individual wells, impose limits on extractions, mitigate against overdraft, implement rules and regulations, and assess fees to support creation and implementation of a GSP.
Does state funding exist to help with SGMA and GSP planning and implementation?
The Solano Collaborative will be pursuing additional grant funds through the upcoming SGMA implementation funding cycle to support eligible Solano Subbasin GSP implementation costs. The GSA Collaborative will continue to evaluate and pursue other grant funding sources as they become available.
