| Abstract: | The saturated thickness of the Ogallala aquifer in an intensive-study area (12-square miles in northeastern Wichita County) has decreased substantially since the development of irrigation. Water levels have declined 1.08 to 2.22 feet per year during 1950-78. In 1977, saturated thickness in the area ranged from 40 to 80 feet, aquifer storage was about 61,000 acre-feet, and natural recharge was estimated to be 0.28 inches per year. During 1977-78, irrigation wells pumped 7,400 acre-feet per year and water-level declines ranged from 0.91 to 5.05 feet. A groundwater flow model was used to project the changes in water level from 1978 to 1988 in the intensive-study area if pumpage in the model area was (1) one-half, (2) equal to , or (3) double the 1977 rate. Water-level declines would range from 5 to 15 feet, 15 to 30 feet, and 25 to 40 feet, respectively. If pumpage in the intensive study area is changed to one-half or double the 1977 rate, water-level declines would range from 10 to 20 feet or 20 to 25 feet, respectively. (USGS) |
