Abstract

The rapid increase of ground-water withdrawal has caused concern over the future use of the Ogallala aquifer, the principal source of water in Ford County, in southwestern Kansas. Saturated portions of deposits of Tertiary and Quaternary age--excluding the Arkansas River alluvium--form the Ogallala aquifer. Saturated thickness of the Ogallala ranged from 0 to about 350 feet on the downthrown side of the Crooked Creek-Fowler fault and from 0 to about 120 feet on the upthrown side. Ground-water withdrawal was calculated by two methods. The time-discharge method computed withdrawal of about 81,000 acre-feet during 1980 and about 58,000 acre-feet during 1981. The irrigation-requirement method computed withdrawal of about 121,000 acre-feet during 1980 and about 131,000 acre-feet during 1981. Results from the irrigation-requirement method are probably closer to the actual amount of ground-water withdrawal because of problems encountered when applying the time-dischargemethod. Water-level declines between 1939 and 1981 ranged from about 10 to 50 feet. Water withdrawal from the Ogallala aquifer depleted the volume of water in storage by about 688,000 acre-feet (8 percent) during this same period. If withdrawals continue to the point where the water table drops below the top of the bedrock surface on the upthrown side of the Crooked Creek-Fowler fault, base flow in the Arkansas River could cease.
