What the filed reports say.
Every water well drilled in Hardin County since 2001 is meant to be filed with the state by the driller. These are those reports, counted.
Median
256 ft
The middle of 1,840 water wells with a reported borehole depth. Half were drilled shallower, half deeper.
Typical range
115–480 ft
The spread is wide. Eighty per cent of the wells on record finish between 115 and 480 ft, a range of 365 ft, which means the county average is a weak guide to any single property. The wells nearest a parcel are worth more than the county's middle.
Deepest on record
1,606 ft
One well. A single deep hole says what the county can demand, not what it usually does.
Reports on file
1,840
Water-supply wells — domestic, irrigation, stock, public supply — carrying a borehole depth. The county has 2,504 filed reports in total; the rest are monitoring wells, soil borings, test holes and injection wells, which are not water wells and are not counted here.
Water quality
2.2% flagged
39 of 1,795 reports that answered the question flagged injurious water quality. It is the driller's own judgement at the time of drilling, not a lab result, and it is not a map of where bad water is.
How the record moved.
The middle of the record has moved shallower: 290 ft in 2001–2009, 255 ft in 2020 onward, a change of 35 ft. That is what the filed reports show for the county as a whole; it is not a forecast for any one property, and where a well is drilled matters more than when.
- 2001–2009
- 501 wells, median 290 ft.
- 2010–2019
- 877 wells, median 244 ft.
- 2020 onward
- 462 wells, median 255 ft.
What this page cannot tell you.
The state's report index carries some things and not others, and the difference decides what any honest page built on it may say.
Not the depth to water.
Every depth here is how far the hole went, which is deeper — often much deeper — than the level water stands at. The report index does not carry a water level at all; those readings live in the state's groundwater database and its nightly archive, and reach a report from there.
Not a yield.
Where a driller tested a well and wrote down what it made, that is on record elsewhere. It is not in this index, so no number on this page is a gallons-per-minute figure and none should be read as one.
Not a prediction for your parcel.
A county median is a description of 1,840 holes spread across the whole county. The wells that matter for one property are the nearest ones in the most similar ground, which is a different question and the one the check below answers.
Not every well.
Wells drilled before the reporting era, wells never filed, and wells filed with the wrong location are all missing or misplaced. The index is what was submitted, not a census of what exists.
Questions about Hardin County wells.
- How deep are water wells in Hardin County, Texas?
- The median water well in Hardin County, Texas is 256 feet deep, based on 1,840 driller's reports filed with the Texas Water Development Board since 2001. Half the wells on record are between 115 and 480 feet, and the deepest is 1,606 feet. These are borehole depths, not depth to water.
- How much does it cost to drill a well in Hardin County?
- Nobody can quote a Texas well from public records, because the record holds depth and not price. What the record does fix is the part of the price that depends on depth: at a median of 256 ft, with eighty per cent of wells between 115 and 480 ft, a quote built on a much shallower hole than the neighbours drilled is a quote to ask about. Drillers price per foot, plus casing, plus the pump.
- Is there a well on a property in Hardin County?
- The filed reports show wells near an address, not on it — a Texas driller's report often carries the nearest road rather than a surveyed point, so a well can be filed under a neighbour's address or not filed at all. The record raises the question and the seller answers it. A free water check on Texas Water Report draws the parcel and lists the wells around it with their distances, which is the version of this question a record can answer.
- Are wells in Hardin County getting deeper?
- The filed record says shallower: a median of 290 ft in 2001–2009 against 255 ft in 2020 onward. Completion depth follows where people drill as much as it follows the water table, so this is a description of the reports, not of the aquifer.
- What are wells in Hardin County drilled for?
- Mostly domestic — 93% of the water-supply reports on file. The rest are split between the other uses the state records: irrigation (84), stock (23), public supply (14).
