What you can ask
- “What does TWDB Texas Water Wells have for the area or asset I'm working on?”
- “Pull the most recent TWDB Texas Water Wells records and put them in a table.”
- “What does TWDB Texas Water Wells cover, and how fresh is the data?”
About this source
Typed, bounded Texas Water Development Board groundwater records: submitted driller reports, plugging reports, curated GWDB sites, BRACS brackish wells, depth statistics, and major/minor aquifer polygons.

Caveats
- ⚠ Owner names and addresses are null unless includeOwner is explicitly true.
- ⚠ Radius-search results are distance-sorted within each provider offset page, not globally across every matching record.
- ⚠ Aquifer polygons come from the TCEQ Groundwater Contamination Viewer because the corresponding TWDB-hosted layer is tile-only.
