How deep are water wells in Carson County, Texas?

Half of the home water wells drilled in Carson County in the last 10 years are between 325 and 590 feet deep. The median is 400 feet, based on 81 driller reports filed with the state. Drillers measured the water standing a median 280 feet below the surface (64 wells). That is deeper than the Texas median of 250 feet.

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.
