Wells around Chico draw from the Trinity aquifer, in the farm and pasture country of northwestern Wise County. This is north and west of where the Glen Rose Limestone thins out, so the Paluxy and Twin Mountains sands merge into a single body — the Antlers Formation — which is the main producing zone for area wells. Toward the western edge, where the Trinity thins or disappears, older Cross Timbers rock becomes the fallback, usually with more limited yield.
Chico’s rural, agricultural character means most landowners have always depended on private wells. Farm and ranch wells in this area often support crops and livestock, calling for larger diameter casings and higher pump capacities than a typical residential well.
Wise County Permit Requirements
New water wells in Chico and throughout Wise County must be permitted through both TDLR and the Upper Trinity Groundwater Conservation District. The district requires a permit before drilling begins and a completion report after the well is finished, and even exempt domestic and livestock wells must be registered. The district’s spacing rules set minimum distances from property lines and neighboring wells, while TDLR construction standards govern separation from septic systems.
