I spent years telling people to ask how deep the well goes before buying. Depth feels concrete, measurable, reassuring. I was wrong to emphasize it.
What actually matters is which aquifer that well is drawing from and whether that aquifer is legally protected by a groundwater conservation district with real enforcement teeth. A 900-foot well tapping an unregulated, heavily pumped formation can go dry faster than a shallow well in a carefully managed district.
I learned this firsthand when a neighbor's municipal expansion permit legally devastated draws across our shared formation — and my deep well meant nothing. The GCD in my county at the time had almost no pumping caps.
Before you close on any rural Texas property — or frankly any state with layered aquifer systems — get the GCD rules in writing, find out what the district's current exempt-use thresholds are, and look up whether any large permitted wells sit within a two-mile radius on the state's online well database.
Anybody here bought land assuming aquifer depth equaled aquifer security and then found out otherwise?
