| Abstract: | The northern High Plains of Colorado, an area of 9,500 square miles (24,600 square kilometers) in the eastern part of the State, is underlain by the Ogallala Formation. Water levels in the Ogallala Formation, the major aquifer in the area, have been declining in areas of ground-water pumping for irrigation. Knowledge of the amount and extent of these declines is necessary for management of the ground-water resource. Water levels have declined as much as 32-40 feet (9.8-12 meters) in an area near Burlington, Kit Carson County, from 1964 to 1976. Maximum declines of 24-32 feet (7.3-9.8 meters) have occurred near the Kiowa-Prowers County line and in a small area northeast of Burlington from 1972 to 1976. Water levels in much of the rest of the area affected by irrigation pumping have declined less than 16 feet (4.9 meters) from 1964 to 1976 and less than 8 feet (2.4 meters) from 1972 to 1976. Water levels have been declining more rapidly in recent years, especially since 1974. (Woodard-USGS) |
