Cardwell ABSTRACT The Kansas River basin in eastern Colorado in the region and by percolation from inter consists mainly of flat upland plains mantled mittent streams and depressions. Ground in places by sand hills and dissected only by water is discharged from the ground-water res the valleys of the main streams. In this ervoir by movement into adjacent areas to the semiarid region, which has an average annual east and southeast, by evaporation and tran precipitation of about 1? inches, farming and spiration in areas of shallow water table, the raising of livestock are the principal by seepage into perennial streams, and by occupations. Irrigation, which has increased wells. All water used for domestic, stock, greatly since 19^0, is practiced in several public, and industrial purposes and most of places in the region. the water for irrigation is obtained from wells. The exposed rocks in the region are of Cretaceous to Recent age. Much of the region Most of the wells in the area are drilled. is underlain by the Ogallala formation of In 1950, 66 of the wells supplied water to Tertiary (Pliocene) age. The Sanborn forma irrigate 5,?60 acres. The areas most favor tion of Pleistocene and Recent(?) age overlies able for the development of irrigation are the Ogallala formation in the southeastern southeast of Holyoke, Phillips County; south part of the region, and the Pierre shale of east of Burlington, Kit Carson County; and Cretaceous age, which underlies the Ogallala the valley of the Arikaree River in the vi formation throughout the region, crops out in cinity of Cope, Washington County. the more deeply incised valleys. Many parts of the upland area are underlain by dune sand, The ground water from the Ogallala forma and the principal valleys are underlain by tion is moderately hard but is suitable for alluvium of Quaternary age. The Ogallala most uses. Water from the alluvium of Recent formation contains thick beds of sand and age generally is much harder. gravel, which yield quantities of water suffi cient for irrigation in many places. The The field data upon which most of this re slope of the surface of the Pierre shale is port is based are given in tables, which in about 33 feet per mile to the north-northeast. clude records of 178 wells and a compilation of data on irrigation wells. Logs of 3^9 The ground-water reservoir is recharged test holes, water wells, and seismograph shot principally by precipitation that falls with holes are included in the report. INTRODUCTION Location and extent of region Purpose of the investigation The region includes all the Kansas River basin in Colorado. It extends southward from the South Platte Valley to Cheyenne Wells and This investigation was begun by the United westward from the Colorado State line to States Geological Survey at the request of the Fleming in the north and Genoa in the south. United States Bireau of Reclamation as a part (See fig. 1.) It includes all of Kit Carson, or the program of the Interior Department for Yuma, and Phillips Counties and parts of development of the Missouri River basin. The Cheyenne, Elbert, Lincoln, Logan, Sedgwick, investigation was endorsed also by the Colo and Washington Counties. The region, which rado State Water Conservation Board. is about 150 miles north and south and aver aging about 60 miles east and west, contains Ground water is one of the important natu about 9*000 square miles. ral resources of eastern Colorado, and each year more irrigation wells are constructed for its further utilization. Irrigation wells are concentrated locally in widely separated Methods of investigation areasj significantly, however, individual wells of large yield are scattered between the areas of concentration. (See pi. 1.) The investigation was begun in July 1950 under the general supervision of A. N. Sayre, The pumping of ground water for irrigation chief of the Ground Water Branch of the U. S. in this area is increasing rapidly. Although Geological Survey, and of G. H.

A lowering of the water table prob ably would result also in greater infiltration Measurements of the water level in 22 wells to- the ground-water reservoir of flood waters scattered throughout the region were made in the upper reaches of intermittently flow monthly. Most of the observation wells are ing streams. Although this recharge might in the areas of greatest concentration of not materially increase yields from wells in irrigation wells. eastern Colorado, it probably would reduce appreciably the direct stream discharge into Of the 178 wells included in the inventory, the surface reservoirs that have been built 121 are or are to be irrigation wells, ^1 are by the Bureau of Reclamation on the lower public supply wells, 12 are abandoned domestic reaches of these streams. or stock wells used as water-level observation wells, 3 are stock wells and 1 is a cemetery All known irrigation and public-supply well.

When possible, the wells in the area were inventoried during total depth of the well and the depth to the this investigation and the resulting data have static water level were measured using a steel been tabulated.
