Updated every day from Texas Water Development Board driller reports. Last update: November 10, 2026, using the state file of November 9, 2026. These are depths of real wells drilled nearby, not a promise about any property. Groundwater can change over short distances and with drought. A licensed water well driller can tell you what to expect on a specific tract.
