Texas Groundwater & Well Lookup

Can you drill here, and what are the rules? Find out in seconds — free, and without making an account.

Texas works fundamentally differently from every other state here. Groundwater follows the "rule of capture," not prior appropriation — there's no state-tracked "water right" with a priority date the way Colorado, Idaho, Utah, Montana, or Nevada have. Ownership is simply an incident of owning the land above it. So instead of water rights, this looks up what is genuinely tracked in Texas: the parcel, which Groundwater Conservation District (if any) regulates it, and nearby wells on file.

Landowners & ranchers

Texas has no state water right to look up — what matters is your district's rules. See spacing, production limits and permit thresholds where they apply.

Buying or selling land

Check the parcel, which district regulates it (81 counties have none), and the wells already on file nearby before you close.

Water professionals

District rules pulled from each district's own management plan, with the source document linked. Tell us what you'd need from a bulk or API tier.
