Since 1963 use of ground water for irrigation in the Oklahoma panhandle has increased greatly as illustrated by the rapid increase in the number of irrigation wells (fig. 1). Because of increased use of ground water, the U.S. Geological Survey, in cooperation with the Oklahoma Water Resources Board, in 1966 began detailed study of the area's ground-water resources. As part of this study, physical data such as well depth, well yield, or water level was collected on approximately 1,500 water wells and test holes; these data are tabulated in this report. This information will be useful to those concerned with development of ground water in the panhandle.
The locations of all known irrigation wells drilled before 1972 and selected domestic and stock wells in Beaver, Cimarron, and Texas Counties are shown in figures 2, 3, and 4, respectively. More wells are shown on the map than are listed in the table because for several hundred wells no information other than location is available.
The generalized section of geologic formations briefly describes the character and water supply available from each unit.
