Ground-water resources in the Bountiful area, Utah, were studied to document changes in ground-water conditions and to simulate the effects of increased ground-water withdrawals and changes in recharge. The aquifer system is in basin-fill deposits and is primarily a confined system with unconfined parts along the mountain front. Recharge to the aquifer system was estimated to range from...

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).

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...

National Water Summary 1988-89 - Hydrologic Events and Floods and Droughts documents the occurrence in the United States, Puerto Rico, and the U.S. Virgin Islands of two types of extreme hydrologic events floods and droughts on the basis of analysis of stream-discharge data. This report details, for the first time, the areal extent of the most notable floods and droughts in each State...

The purpose of this report is to provide a quantitative analysis of the occurrence, movement, and quality of water and the hydrologic characteristics of aquifers and confining units in the Mesozoic rocks of the Upper Colorado River Basin. The analysis is regional in scope and, hence, does not address site-specific problems caused by intricate localized quality, lithologic, or structural

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 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...

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...

The ground-water resources in the East Shore area of Great Salt Lake, Utah, were studied to better define the ground-water system; to document changes in ground-water levels, quality, and storage; and to simulate effects of an increase in ground-water withdrawals. The East Shore aquifer system is in basin-fill deposits, and is primarily a confined system with unconfined parts near the...

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...

Water resources data for the 1989 water year for Utah consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water quality of ground water. This report contains discharge records for 185 gaging stations; stage and contents for 22 lakes and reservoirs; water quality for 21 hydrologic stations and 217 wells; miscellaneous...
