The Ogallala Aquifer: Where Randall County Gets Its Water
Randall County sits above the Ogallala Aquifer, the main source of water for drinking and farming, and levels have been dropping for decades.
The Ogallala Aquifer runs under the Texas Panhandle and supplies most of the water used for irrigation and city needs in this region. About 95% of groundwater pumped from it goes to agriculture. The problem is that more water is pumped out than nature puts back in, so water levels keep falling. In some areas, the aquifer has dropped more than 300 feet since large-scale irrigation began in the mid-1900s.
If you buy rural land or a home with a private well in Randall County, knowing the local water depth matters. The Texas Water Development Board (TWDB) has done detailed studies of the Ogallala in Randall County. Check their site at twdb.texas.gov for aquifer maps and water-level data before you drill a new well or buy irrigated land.
