The 2014 Sustainable Groundwater Management Act (SGMA) provides a framework for sustainable management of groundwater resources by local authorities. The act establishes a timeline - 20 years - to implement actions that achieve long-term groundwater sustainability. It protects existing surface water and groundwater rights and does not impact drought response measures. The Department of Water Resources (DWR) is in charge of the SGMA Program and has developed guidelines for local agencies to follow.

Groundwater Sustainability Agency (GSA) was formed for the Napa Valley Subbasin in order to be in compliance with SGMA and DWR regulations, otherwise the Subbasin would be deemed "unmanaged." If a GSA was not formed, the State Water Resources Control Board (SWRCB) would be obligated to step in to monitor and manage groundwater users. The SWRCB could require all groundwater users within the Subbasin to install meters, report extractions, and pay fees to cover State costs.

On December 17, 2019, the Napa County Board of Supervisors conducted a public hearing under Water Code section 10723 and adopted a resolution affirming Napa County's intention to manage groundwater in the Napa Valley Subbasin and to form the Napa County Groundwater Sustainability Agency (GSA) pursuant to Water Code section 10724, and authorized the submittal of GSA Formation Information to DWR. Water Code section 10724 provides that the County is presumed to be the GSA for the areas in the Subbasin that are "unmanaged" (not within the management of GSA). DWR's SGMA website portal provides local agencies, GSA's, and watermasters the ability to submit, modify, and view the information required by SGMA, and enables the public and interested stakeholders to view submitted information and provide comments, where applicable. No login is required for public access.

On January 7, 2020, the Napa County GSA held its first meeting. The agenda for this first meeting was to elect officers, appoint an executive officer, adopt a 2020 meeting calendar, and approve a resolution authorizing the submittal of a $2.6 million dollar grant application to DWR to support the development of a Groundwater Sustainability Plan (GSP) for the Napa Valley Subbasin. The new GSA is required to develop  a GSP for the Napa Valley Subbasin and submit it to DWR by January 2022.

On February 6, 2020, the Napa County GSA submitted notification to the Department of Water Resources of their intent to prepare a Groundwater Sustainability Plan for the Napa Valley Subbasin.

The next meeting of the Napa County GSA will be March 17, 2020. Additional details on upcoming GSA meeting can be found on the GSA's agendas and minutes webpage.
