Ground-water levels in a 600 square mile area of the Cumberland River drainage basin in parts of Trigg, Lyon Caldwell, and Christian Counties, Mississippian Plateau Region, Kentucky are shown by means of contours on the potentiometric surface. Generaly, ground water moves toward and with the surface drainage to Lake Barkley and the Cumberland River. The potentiometric map indicates a minimum drilling depth to water. The bedrock is composed largely of sandstone, cavernous limestone, or jointed and fractured limestone. All of these rock types yield sufficient water for domestic and stock purposes. The cavernous limestone is extremely vulnerable to pollution. (Kosco-USGS)
