Callahan County has no groundwater conservation district

A groundwater conservation district is the local board that can set pumping, spacing, and permit rules for wells. TWDB's current district map does not show a district covering Callahan County.

TCEQ says land outside a groundwater conservation district falls under the rule of capture. groundwater brought up by a well generally belongs to the landowner, with limits for waste, malice, and certain damage.

If a rural tract depends on a well, check the current TWDB district map during due diligence. Ask for the driller's log, then have the water tested and the well checked by someone who works this part of the county.
