Managing Groundwater in the Tracy Subbasin
Under California’s Sustainable Groundwater Management Act (SGMA), local agencies that manage groundwater – including those in the Tracy Subbasin – must form Groundwater Sustainability Agencies (GSA) and develop a Groundwater Sustainability Plan (GSP). The final GSP was submitted to the state in January 2022. The Tracy Subbasin is now in the GSP implementation phase.
Six GSAs formed in the Tracy Subbasin and are working cooperatively to implement a single GSP. These GSAs are:
- Banta-Carbona Irrigation District
- Byron-Bethany Irrigation District
- City of Lathrop
- City of Tracy
- County of San Joaquin
- Stewart Tract
The map below shows the location of the six agencies in the Tracy Subbasin.
