Santa Ynez River Valley Groundwater Basin

There are three Management Areas in the Santa Ynez River Groundwater Basin (Basin), the Western Management Area (WMA), Central Management Area (CMA), and Eastern Management Area (EMA). Each Management Area is governed by a Groundwater Sustainability Agency (GSA) with input from a GSA Committee. These GSAs and Committees are working together to develop Groundwater Sustainability Plans (GSPs) for the Basin which will be managed under a coordination agreement per GSP regulations.

California's Sustainable Groundwater Management Act (SGMA) requires the preparation and implementation of a GSP for each High and Medium priority groundwater basin in the state. The Santa Ynez River Valley Groundwater Basin is a medium priority basin and must be managed under a GSP by January 31, 2022.

The primary purpose of this website is to facilitate communication with interested parties so they may participate in SGMA implementation, including development of a GSP.
