The ground-water resources in Ogden Valley, eastern Weber County, Utah, were the subject of a study to provide a better understanding of the hydrologic system in the valley and to estimate the hydrologic effects of future ground-water development. The study area included the drainage basin of the Ogden River upstream...

Communities in southeastern Tooele Valley, Utah, are growing, and future demand for water is expected to increase. To prepare for this demand, local surface- and ground-water resources were evaluated.Average streamflow in Settlement, Middle, and Soldier Canyons is about 6,000, 2,100, and 3,900 acre-feet per year, respectively. The combined average perennial...

A hydrologic investigation of Cache Valley was done to better understand the ground-water system in unconsolidated basin-fill deposits and the interaction between ground water and surface water. Ground-water recharge occurs by infiltration of precipitation and unconsumed irrigation water, seepage from canals and streams, and subsurface inflow from adjacent consolidated rock...

An areal survey of surficial sediments in San Francisco Bay has been conducted to evaluate the presence of extractable organic compounds. Molecular marker compounds studied include hydrocarbons (PAH's), chlorinated pesticides, and other organic compounds that provide information on sources of organic input into the Bay. Fairly uniform source profiles are...

The pilot program described here is motivated by a fundamental principle of the Regional Monitoring Strategy, namely “...the development of data that will provide information on status and trends in the Estuary.” As pointed out in the Strategy, knowledge of status and trends serves two primary purposes: (1) to become...

The U.S. Geological Survey (USGS) is assessing the ground.water resources of the carbonate bedrock aquifers in Indiana and Ohio as part of their Regional Aquifer Systems Analysis program. Part of this assessment includes the determination of unknown aspects of...

Hydrologic controls on sulfate mobility were investigated in a forested catchment in the Georgia Piedmont using a watershed mass balance approach. Variations in annual sulfate export were governed primarily by differences in runoff rather than by differences in sulfate deposition or in total annual precipitation. However, 2 years with similar...

During the late Quaternary, the elevation of terrace cutting and carbonate deposition in the Pyramid Lake subbasin were controlled by constancy of lake level imposed by spill to adjoining subbasins. Sill elevations are 1177-1183 m (Mud Lake Slough Sill), 1207 m (Emerson Pass Sill), and 1265 m (Darwin Pass Sill)....

The genetic population structure of the recently introduced Asian clam, Potamocorbula amurensis, in San Francisco Bay was described using starch gel electrophoresis at eight presumptive loci. Specimens were taken from five environmentally distinct sites located throughout the bay. The population maintains a high degree of genetic variation, with a...

The Travertine District (Park) of the Chickasaw National Recreation Area, operated and maintained by the National Park Service, is near the City of Sulphur in south-central Oklahoma. The Park was established in 1902 because of its unique hydrologic setting, which includes Rock Creek, Travertine Creek, numerous mineralized and freshwater springs,...

This report is a compilation of hydrologic, water- quality, and meteorologic data collected in the vicinity of Newberry Volcano near Bend, Oregon. These data were collected, in cooperation with the Bonneville Power Administration, the U.S. Forest Service, and the Bureau of Land Management, to provide baseline data for identifying and...

Sixty-three water samples collected during June to October 1982 from the Leviathan/Bryant Creek drainage basin were originally analyzed by simultaneous multielement direct-current plasma (DCP) atomic-emission spectrometry, flame atomic-absorption spectrometry, graphite-furnace atomic-absorption spectrometry (GFAAS) (thallium only), ultraviolet-visible spectrometry, and hydride-generation atomic-absorption spectrometry.Determinations were made for the following metallic and semi-metallic constituents:...

Since 1984, hydrologic data have been collected as part of a U.S. Geological Survey study of the occurrence and movement of acidic contamination in the aquifer and streams of the Pinal Creek drainage basin near Globe, Arizona. Ground-water data from that study are presented for water years 1992 and 1993...

The data sets on this compact disc are a compilation of several geographic reference data sets of interest to the global-change research community. The data sets were chosen with input from the Global Energy and Water Cycle Experiment (GEWEX) Continental-Scale International Project (GCIP) Data Committee and the GCIP Hydrometeorology and...

The Mississippi River and some of its tributaries were sampled for natural organic substances dissolved in water and in suspended and bed sediments during seven sampling cruises from 1987-90. The sampling cruises were made during different seasons, in the free-flowing reaches of the river from St. Louis, Missouri, to New...

Ground water in the Quaternary alluvium and terrace deposits associated with the Cimarron River in northwestern Oklahoma is used extensively for irrigation, municipal, stock, and domestic supplies. The data in this report were collected as part of an investigation to provide State water managers with the quantitative knowledge necessary to...

The hydrology and water quality of Whitewater and Rice Lakes was studied by the U.S. Geological Survey during November 15, 1990November 14, 1991, in cooperation with the Whitewater-Rice Lakes Management District, Walworth County, Wis. Whitewater and Rice Lakes are small, shallow lakes; surface areas are 697 and 162 acres and...

Rapid industrial and urban growth is anticipated in the vicinity of Crowders Creek near Clover, S.C., and Steele Creek near Fort Mill, S.C. These subbasins are in the Catawba River Basin in York County, S.C. To obtain baseline information on these basins prior to urbanization, gaging stations 02145642 (Crowders Creek...

November of water into and out of tidally affected canals in eastern North Carolina was documented before and after the installation of water-control structures. Water levels in five of the canals downstream from the water-control structures were controlled primarily by water-level fluctuations in estuarine receiving waters. Water-control structures also altered...

The U.S. Geological Survey, in cooperations with the U.S. Army Corps of Engineers, conducted a study during October 1993-April 1994 to improve an understanding of the hydrology of the Lost River watershed near Orleans, Ind. Elements of the study included: (1) constructing a map of the composite ground-water potentiometric-surface of...
