Source and method: Texas Water Development Board Submitted Driller's Reports database, extracted 2026-07-14. Figures include only wells recorded as residential (domestic) use, completed 2011 or later, with a reported depth between 15 and 2,000 ft (to exclude likely data-entry errors). TWDB itself notes well locations and data "are not verified by State staff and may be inaccurate," and neither TWDB nor this site independently verifies them. These are figures self-reported by licensed drillers to the state; treat this as a planning reference, not a guarantee for any specific property.
