How Deep Are Wells in Texas? Real Depth Data by County

"How deep will my well need to be?" is one of the hardest well-drilling questions to answer in the abstract, because it depends entirely on local geology. Texas is one of the few states that publishes every driller's completion report as open data, so instead of a national average, here is what 184,832 actual residential wells drilled since 2011 report for depth, broken down by county.

Source and method: Texas Water Development Board Submitted Driller's Reports database, extracted 2026-07-14. Figures include only wells marked "Domestic" (residential) use, completed 2011 or later, with a reported total depth between 15 and 2,000 ft (to exclude likely data-entry errors). A county is shown only if it has at least 5 qualifying reports. These are figures self-reported by licensed drillers to the state; 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. Treat this as a planning reference, not a guarantee for any specific property, your own site could sit well outside your county's typical range.

Median well depth by county

"Typical range" is the 10th-to-90th-percentile band, i.e. where 80% of reported wells in that county fell. Counties with fewer than 5 qualifying reports since 2011 are omitted rather than shown with a misleading precise figure.

How to use this table

Find your county, then use the median and typical-range figures as a starting point when budgeting with the well drilling cost estimator or reading the cost guide. A driller working in your county day-to-day will still know more about your specific property than a county-wide figure can, ask them how your site compares to the county's typical range, and why, before you commit to a per-foot quote with no depth ceiling.

This page currently covers Texas only, since Texas publishes the cleanest public completion-report dataset of the states in this directory. We plan to extend the same method to other states as their public well-log data allows.
