Leon County has a groundwater district that oversees water wells

A Leon County well is local water, but it is not a free-for-all. The Mid-East Texas Groundwater Conservation District covers all of Leon, Madison, and Freestone counties. Its current rules set spacing for new wells. Non-exempt wells need drilling and operating permits. Permitted wells get production limits.

That sounds fussy until you are buying land, picking a homesite, or trying to reuse an old well. Call the district before the driller is booked. Ask whether the well is exempt, whether it is registered, how far it must sit from property lines and other wells, and whether a pumping limit applies.

The aquifer piece is worth asking about too. The district's 2024 management plan lists Carrizo-Wilcox groundwater in Leon County. TWDB describes the Carrizo-Wilcox as a major Texas aquifer. In plain terms: get the district answer early, then build the well plan around it.
