The chemical quality of water in the southeastern Uinta Basin, Utah and Colorado, is important to the future development of the abundant oil-shale resources of the area. This report examines the observed changes in chemistry as water circulates in both shallow and deep ground-water systems. Mass-balance and mass- transfer calculations are used to define reactions that simulate the observed water c

A one-dimensional numerical model is presented for simulating the unsteady flow in singular riverine or estuarine reaches and in networks of reaches composed of interconnected channels. The model is both general and flexible in that it can be used to simulate a wide range of flow conditions for various channel configurations. The channel geometry of the network to be modeled should be sufficiently

During several periods of volcanic-ash eruption at Mount St. Helens, Wash., (March 30, May 25-26, May 30-June 2, and June 12-13, 1980) strong winds from the north occurred at high altitudes. As a result, the volcanic ash fell some 50 miles to the south in the Bull Run watershed, the principal water-supply source for the metropolitan area of Portland, Oreg. Water samples collected from three stream

Data obtained during a hydrologic reconnaissance in 1975-77 in the Wasatch Plateau-Book Cliffs coal-fields area of Utah were correlated with existing long-term data. Maps were prepared showing average precipitation, average streamflow, stream temperature, ground- and surface-water quality, sediment yield, and geology. Recommendations were made for additional study and suggested approaches for cont

The High Plains aquifer in Kansas is part of a regional system that extends into Colorado, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming.  The aquifer in Kansas underlies an area of 31,000 square miles in the western and south-central part of the State.  This aquifer is a hydraulically connected assemblage of unconsolidated water-bearing deposits.  In western Kansas, the High Pl

This map shows water-level contours for the shallow aquifers in the La Grange area of southeastern Wyoming and adjacent Nebraska as of April 30, 1980. Water-level measurements made on April 30, 1980, provided the principal control for most of the area of the map. Measurements made in April 1979 were used as control for some areas that are remote from centers of pumping. The contours are shown at a

Volume 4 of the water resources data for the 1980 water year for California consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality in lakes and reservoirs; and water levels in wells. This report contains discharge records for 199 gaging stations; stage and contents for 34 lakes and reservoirs; precipitation data for stations; water quality for sta

A map of the water table in Graham County, prepared in collaboration with the U.S. Bureau of Reclamation, provides current (1980) information on water levels in the unconsolidated deposits. Graham County, an area of 900 square miles in northwestern Kansas, is within the rolling, moderately to well-dissected terrain on the eastern edge of the High Plains.  The eastward-flowing South Fork Solomon Ri

This is the eighteenth in a series of annual reports that describe ground-water conditions in Utah. Reports in this series, prepared 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 construction,

A test-drilling program in Tooele Valley, Utah, was conducted by the U.S. Geological Survey in cooperation with the Utah Department of Natural Resources, Division of Water Rights. The basic data and interpretation of each test hole are included in this report. Results obtained from the test drilling were used in a comprehensive ground-water investigation of the valley fill (Razem and Steiger, 1981

This report presents data for public water suppliers in Utah during 1979. A public water supply system supplies water for human consumption and other domestic uses. It can be publicly or privately owned and includes systems supplying water to cities, subdivisions, federal installations, summer homes, and camping areas. The data were collected through questionnaires mailed to the various public wat
