An investigation of the hydrologic system in Heber and Round Valleys was conducted to improve understanding of the surface-water and ground-water hydrology and the effects caused by changes in recharge. Ground water is present in consolidated rocks and in unconsolidated valley-fill deposits, but the principal ground-water reservoir is in the unconsolidated valley-fill deposits. Recharge...

This report is a summary of data collected under the Utah Water Use Program, a cooperative program between the Utah Division of Water Rights and the United States Geological Survey (USGS).

Physical, chemical, and biological data were collected in the middle Green River basin, eastern Utah, between 1988 and 1989, as part of a detailed study of the effects of irrigation drainage on wetland areas. Data-collection efforts were concentrated in the Stewart Lake Waterfowl Management Area near Jensen, and Ouray National Wildlife Refuge near Ouray. Data also were collected from...

The base of moderately saline ground water (water that contains from 3,000 to 10,000 milligrams per liter of dissolved solids) was delineated for San Juan County, Utah, based on water-quality data and on formation-water resistivities determined from geophysical well logs using the resistivity-porosity, spontaneous-potential, and resistivity-ratio methods. These data and the contour map...

This report contains summaries of the progress of water-resources studies in Utah by the U.S. Geological Survey, Water Resources Division, Utah District, from October 1, 1988, to September 30, 1989. The program in Utah during this period consisted of 21 projects; a discussion of each project is given in the main body of the report. The following sections outline the basic mission and...

The Grand County area includes all of Grand County, the Mill Creek and Pack Creek drainages in San Juan County, and the area between the Colorado and Green Rivers in San Juan County. The Grand County area includes about 3,980 square miles, and the Mill Creek-Spanish Valley area includes about 44 square miles. The three principal consolidated-rock aquifers in the Grand County area are the...

The primary ground-water reservoir in Pahvant Valley and adjacent areas is in the unconsolidated basin fill and interbedded basalt. Recharge in 1959 was estimated to be about 70,000 acre-feet per year and was mostly by seepage from streams, canals, and unconsumed irrigation water and by infiltration of precipitation. Discharge in 1959 was estimated to be about 109,000 acre-feet and was...

The Great Salt Lake in Utah is a large body of water bordered on the west by barren desert and on the east by a major metropolitan area. It is the fourth largest terminal lake in the world, covering about 2,300 square miles in 1986. Since its historic low elevation of 4,191.35 feet in 1963, the lake rose to a new historic high elevation of 4,211.85 feet in 1986. Most of this increase (12...

This is the twenty-seventh in a series of annual reports that describe ground-water conditions in Utah. Reports in this series, published cooperatively by the U.S. Geological Survey and the Utah Division of Water Resources, provide data to enable interested parties to keep abreast of changing ground-water conditions. This report, like the others in the series, contains information on...

Six regions in the Basin and Range province, ranging in size from 21,600 to 80,000 square kilometers, were evaluated to identify prospective hydrogeologic environments for isolation of high-level radioactive waste. Prospective hydrogeologic environments were evaluated on the basis of the surface distribution of potential host rocks, late Cenozoic tectonic activity, hydrogeologic...

Water use in the United States, as measured by freshwater withdrawals in 1985, averaged 338,000 Mgal/d (million gallons per day), which is enough water to cover the 48 conterminous States to a depth of about 2.4 inches. Only 92,300 Mgal/d, or 27.3 percent of the water withdrawn, was consumptive use and thus lost to immediate further use; the remainder of the withdrawals (72.7 percent)...
