The Ogallala Aquifer Is Deep Here — and You Need a Permit to Drill
The Ogallala Aquifer reaches its greatest thickness in the Texas Panhandle. In southwestern Ochiltree County, the aquifer can be nearly 900 feet thick. That is unusually deep. Most homes and farms in the county depend on this underground water source for drinking water and irrigation.
The North Plains Groundwater Conservation District covers Ochiltree County. Before you drill a well, you must contact the district and obtain a permit. The district also collects water quality data and issues test-hole permits. Drilling without a permit can result in fines. The district office is in Dumas, Texas, at 603 E. 1st St., and can be reached at (806) 935-6401. Visit northplainsgcd.org for permit applications and more information.
