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 July 1, 1986 to June 30, 1987. The program in Utah during this period consisted of 24 projects; a discussion of each project is given in the main body of the report. Short descriptions are given at the end of the report for six...

This is the twenty-fifth 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 well

This atlas is one of several reports that are products of an analysis of regional aquifer systems in the Great Basin of Nevada, Utah, and adjacent States. The Geological Survey program of regional aquifer-system analyses is a nationwide study of ground-water systems on a regional scale. The program is intended to establish a framework of geologic, hydrologic, and geochemical information...

This publication is the sixth in a continuing series of reports presenting water use data for Utah. The data are collected by the State of Utah, Division of Water Rights, for the National Water Use Information Program. This is a cooperative effort with the U.S. Geological Survey. Most states contribute information in some form to the program.

The objective of the Upper Colorado Regional Aquifer Systems Analyses (RASA) project is to assess quantitatively the occurrence, movement, and availability of water stored in rock formations underlying the basin. This is one of a series of preliminary reports that describe what is currently known (1984) about the geometry and hydrologic properties of the aquifer systems, and the...

Permits for disposing of salty oil-production water have been issued for 19 wells in the Greater Altamont-Bluebell field. During 1986 more than 500 million gallons of production water were injected into the Duchesne River, Uinta, and Green River Formations through 18 of these wells. The physical and chemical effects of injecting this water into aquifers containing potable water are...

This report summarizes discharge data and other streamflow characteristics developed from gag ing-station records collected through September 1981 at 337 stations in the Colorado River Basin in Utah. Data also are included for 14 stations in adjacent areas of the bordering states of Arizona, Colorado, and Wyoming (fig. 1). The study leading to this report was done in cooperation with the...

Three sets of seepage measurements were made at ten canal sites and at all turnouts along a 15.3-mile section of the Central Utah Canal during the sumner of 1986. The total loss for the 15.3-mile section averaged about 36 cubic feet per second or 2.4 cubic feet per second per mile. The nine subsections were grouped into five reaches of one or more subsections with similar losses per mile...

The base of the moderately saline water (water that contains from 3,000 to 10,000 milligrams per liter of dissolved solids) was mapped by using available water-quality data and by determining formation-water resistivities from geophysical well logs based on the resistivity-porosity, spontaneous potential, and resistivity-ratio methods. The contour map developed from these data showed a...

Studies of selected reaches of the Weber River, Davis-Weber Canal, and the Ogden Valley Canal in Davis and Weber Counties, Utah, were made to determine gains or losses of flow in those reaches. Three to five sets of seepage measurements were made on the river and each canal during 1985. Adjustments for fluctuations in flow were made from information obtained from water-stage recorders...

The potential for developing oil-shale resources in the southeastern Uinta Basin of Utah and Colorado has created the need for information on the quantity and quality of water available in the area. This report describes the availability and chemical quality of ground water, which might provide a source or supplement of water supply for an oil-shale industry. Ground water in the...

This report was prepared in cooperation with several organizations in the Salt Lake Valley and with the Central Utah Water Conservancy District to present results of a study to determine changes in the ground-water conditions in Salt Lake Valley, Utah, from 1969 to 1983, and to predict the aquifer response to projected withdrawals. The average annual recharge and discharge from the...
