What this shows and what it doesn't

A county median hides what happens inside the county: wells a few miles apart can differ by hundreds of feet. Each county page shows its full range.
Depth is how far people drilled, not where the water starts. Wells go past the water level to hold a reserve.
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.

Questions

Which Texas county has the deepest water wells?

McLennan County: the median home well is 1,100 feet deep and the middle half run from 80 to 1,180 feet (88 wells, in the last 10 years).

Which Texas county has the shallowest water wells?

Wichita County: the median home well is 36 feet deep (76 wells, since 2001).

How deep is a typical water well in Texas?

250 feet is the median of the 123,925 home wells drilled in the last 10 years; the middle half run from 170 to 397 feet.

Check it yourself

Download this page's table as a CSV (deepest-and-shallowest-water-wells-texas-counties.csv): every figure in the text is in it.
Open any county in the table. Its page lists its figures, and each well on its map opens the official report on the state's site.
For the raw data, download the state file from the TWDB link in the sources and keep the wells whose proposed use is Domestic and whose work is a new well or a replacement.
If a figure does not match, write to us with the county and the number: we correct it in the next update and say so.

How we got it

We count new and replacement domestic (home) wells with a valid depth on their report. Monitoring wells, soil borings, injection, geothermal and oilfield wells are left out. A depth under 10 feet or over 5,000 feet is treated as an entry error.

County figures use the wells finished in the last 10 years when there are at least 30; otherwise all since 2001. The median is the middle well: half are deeper, half shallower. Only counties with 30 wells or more are ranked.
