Our Mission

The mission of the Yolo Subbasin Groundwater Agency (YSGA) is to provide a dynamic, cost-effective, flexible collegial organization to ensure compliance with SGMA within the Yolo Subbasin.  Each of the Members and Affiliated Parties will have initial responsibility for groundwater management within their respective jurisdictional boundaries and the YSGA serves a coordinating and administrative role for developing and implementing the Groundwater Sustainability Plan. 

Formation of the YSGA

The Yolo Subbasin Groundwater Agency was officially formed on June 19, 2017 for the purpose of acting as the Groundwater Sustainability Agency (GSA) for the Yolo Subbasin.  The Yolo Subbasin Groundwater Agency is considered the exclusive GSA for the Yolo Subbasin, which can be found on the California Department of Water Resources SGMA web portal.
