Welcome

Welcome to the official website of the Turlock Subbasin Groundwater Sustainability Agencies (GSAs) working to develop and implement a Groundwater Sustainability Plan to comply with the Sustainable Groundwater Management Act (SGMA) of 2014 and achieve long-term sustainability of the Turlock Subbasin.

Two (2) GSAs exist in the Subbasin; the East Turlock Subbasin GSA and the West Turlock Subbasin GSA. Each GSA consists of a multiple of public water agencies and municipalities. The GSAs are developing a single groundwater sustainability plan to manage groundwater quantity and quality through at least 2042. The law is primarily regulated by California’s Department of Water Resources.
