The Napa County Groundwater Sustainability Agency oversees Groundwater Sustainability in the County. The Agency is also in charge of creating and carrying out a Groundwater Sustainability Plan (GSP) for the Napa Valley Subbasin. An advisory committee is helping the Agency create the GSP.

The GSP will include policies and recommendations for taking care of and protecting groundwater within the Subbasin for the long term. The committee will submit a draft GSP for the Agency to review by November 1, 2021.
