Texas Water Well Reports · TDLR SDR
TDLR SDR well records, searchable by address
Every Texas well log is filed with the Texas Department of Licensing and Regulation Submitted Driller's Reports (SDR) database, administered by the Texas Water Development Board. Those records are public, but they are organized by mapped location and record number — not by street address. We hold 456,465 of them and rebuild the index weekly, so you can start from an address instead.

Enter any Texas address and we return the wells recorded around it — wells are plotted at the location reported by the driller (street address + lat/lon), typically within a few hundred feet; about 95% of reports carry a street address.

Not every filed report carries every field — older records are thinner, and what the state captured changed over the decades. This is the real coverage across all 456,465 records, so you know what to expect before you search.
| Field | What it tells you | Records with it | Coverage |
|---|---|---|---|
| Date completed | When the well was finished and the log filed. | 456,465 (100%) | |
| Mapped location | Coordinates, so the log can be found by address instead of by record number. | 456,406 (100%) | |
| Total depth | How deep the hole was drilled, in feet. | 456,213 (100%) | |
| Driller | The licensed company that drilled the well and signed the log. | 456,038 (100%) | |
| Street address | A street address on the filed report (varies a lot by state and era). | 434,912 (95%) | |
| Static water level | How far below the surface the water stood at rest. | 334,794 (73%) | |
| Tested yield | Gallons per minute the well produced on the driller’s pump test. | 328,940 (72%) |
How this differs from going to TDLR/TWDB directly
Nothing here replaces the official record, and for a single well you already have the record number for, TDLR/TWDB is the place to go (www.twdb.texas.gov/groundwater/data/drillersdb.asp). What this site adds is the part that is hard from the source data:
- An address is enough. You do not need a record number, a section-township-range, or a latitude to start. Wells are plotted at the location reported by the driller (street address + lat/lon), typically within a few hundred feet; about 95% of reports carry a street address.
- The neighbours, not just the well. Buyers and lenders care what depth and yield are normal nearby, which means reading many records at once, not one.
- The same statistics everywhere. Median depth, static water level and yield are computed identically in every county, so two counties can actually be compared. The exact filters are on the methodology page.

Common questions
With TDLR SDR — the Texas Department of Licensing and Regulation Submitted Driller's Reports (SDR) database, administered by the Texas Water Development Board. Every Texas driller files a completion report there for each well drilled, and that filing is the authoritative copy of the record. The official site is www.twdb.texas.gov/groundwater/data/drillersdb.asp.
Not directly — well records are filed against a mapped location and a record number, not a mailing address, which is the single most common reason people give up on the search. That is exactly the gap this site fills: enter an address on our free lookup and we return the recorded wells around that point, wells are plotted at the location reported by the driller (street address + lat/lon), typically within a few hundred feet; about 95% of reports carry a street address.
No, and it is not meant to be. This is an independent index built from the data TDLR/TWDB publishes, rebuilt weekly. For the authoritative copy of any single record, go to TDLR/TWDB directly. If our copy and the state's ever disagree, the state's is right.
Our current copy holds 456,465 records across 254 counties, with completion dates from 1950 to 2026. That is everything TDLR SDR publishes in its bulk record set as of 2026-07-28. Wells drilled before the state's filing requirement — and hand-dug or unpermitted wells — were never filed anywhere, so they are in neither copy.
Searching by address here is free, the same as searching TDLR SDR is free. What we charge for is the compiled property report — every recorded well near one address, with the statistics and the original log links, as one printable document for a sale or a loan file. That is $19.
The property report pulls every recorded well near an address — depths, water levels, yields, drillers — as one printable summary for due diligence.
