Description

This data set consists of digitized water-level elevation contours for the Enid isolated terrace aquifer in northwestern Oklahoma. The Enid isolated terrace aquifer covers approximately 82 square miles and supplies water for irrigation, domestic, municipal, and industrial use for the City of Enid and western Garfield County. The Quaternary-age Enid isolated terrace aquifer is composed of terrace deposits that consist of discontinuous layers of clay, sandy clay, sand, and gravel. The aquifer is unconfined and is bounded by the underlying Permian-age Hennessey Group on the east and the Cedar Hills Sandstone Formation of the Permian-age El Reno Group on the west. Cedar Hills Sandstone Formation fills a channel beneath the thickest section of the Enid isolated terrace aquifer in the midwestern part of the aquifer. The water-level elevation contours were digitized from a photocopy of a paper map in a ground-water modeling thesis and report. The map digitized was published at a scale of 1:62,500 shows that the ground-water elevations in 1973 ranged from about 1,360 feet above sea level at the northwestern edge to about 1,150 feet above sea level at the southeastern edge of the aquifer.
