U.S. Geological Survey. For the 25th consecutive year, the USGS, in cooperation with the Utah Division of Water Rights, has prepared water-level-change maps for basins and other areas with significant ground-water use. Cedar Valley was the only area in the state where the number of wells with measured water-level rises (60 percent) outnumbered wells showing declines (40 percent). However, water levels in nearby i Uah Valley declined in all wells I measured except those completed in the water-table aquifer. Declines were noted in more than 90 percent of the wells surveyed in Salt Lake, 1 Tooele, Cache and Juab Valleys, as ; well as the East Shore and Beryl-' Beryl-' Enterprise areas. Water-level rises were measured in about 40 percent of the wells in the survey in Pahvant, Curlew and Cedar (Iron Co.) valleys, the central Virgin area, the shallow artesian aquifer in Sevier Desert, and the water-table aquifer in Utah s and Goshen Valleys. Map of Utah County shows change of ground water levels in water-table aquifers, March 1987 to March 1988. The largest water-level decline 30.4 ft. in a well tapping the deep measured from February-March artesian aquifer in Utah Valley, 1987 to February-March 1988 was See WATER on page 2 Water Continued from front page south of Alpine. Water-level declines in this area and throughout the state are probably the result of below normal preciptation and increased ground-water withdrawl for irrigation, municipal and in dustrial uses. The largest water-level rise was 15 ft. in a well in the shallow artesian ar-tesian aquifer in the Sevier Desert north of Delta. The rise in this well is probably related to a decrease in pumping due to the availability of greater than normal supplies of surface water for irrigation. Copies of the maps can be obtained ob-tained at the offices of the U.S. Geological Survey, Water Resources Division, Room 1016 Administration Building, 1745 W. 1700 South, Salt Lake City 84106. The maps will be included in a report, "Developing a State Water Plan, Ground-water Conditions in Utah, Spring of 1988," which will be released later this year. |
