Official Texas Groundwater Observation Sources
Groundwater observations describe agency records at identified wells, stations, regions, and dates. They can add context to research, but they do not predict conditions at an unmonitored property or establish the performance of a private well.

Useful research questions
What this source family may help answer
- Is a TWDB well identifier or dated groundwater observation available?
- What recent measurement and station context is displayed for a participating recorder well?
- Which agency date and source notes should be preserved before comparing observations?
Keep the boundary visible
What it cannot answer
- Groundwater conditions at a specific property or an unmonitored well.
- Future water availability, private-well yield, water quality, or property suitability.
- Ownership, title, permit standing, or a complete history of every groundwater observation.
Recommended sequence
Use the sources in a deliberate order
Record the source, identifiers, dates, saved records, and unresolved questions at each step.
- 01
Use the Groundwater Database when you have a well identifier, county, or record-specific observation question.
- 02
Use Groundwater Conditions for recent participating recorder-well and regional context.
- 03
Preserve the well or station identifier, measurement date, source notes, and the date you viewed the record.
- 04
Keep property-level conclusions separate from regional or monitored-well observations.
Troubleshooting
Common search failures
- Comparing measurements without first checking their dates, stations, or record context.
- Assuming a recorder well represents a nearby private well or entire property.
- Searching without a usable well identifier, county, region, or station context.
- Treating a current display as a complete historical archive.

What this page cannot establish
- Measurements apply to the agency record, well, station, and date displayed—not automatically to another well or property.
- The directory does not mirror measurements or provide a live conditions lookup.
- Regional context cannot establish future availability, well performance, suitability, ownership, or compliance.
