A local district regulates water wells in Sutton County
Sutton County is not on its own for well rules. TWDB lists the Sutton County UWCD, its district website, and its 2024 management plan.
The county also sits in Groundwater Management Area 7. That area includes the Sutton district and major aquifers such as the Edwards-Trinity (Plateau).
If you are looking at rural ground near Sonora, call the district before planning a new well or changing an old one. Ask what rules apply, then pull well records before you count on the water supply.
