The relocation of a part (about one-half a mile) of the Catawba River near Marion, North Carolina, and the proposed addition of a main bridge and an overflow bridge of U.S. Highway 221 have created the need for a current evaluation of the effects of these physical changes on floodflow...

There are two types of water-resources activities of the U.S. Geological Survey in Wyoming: collection of hydrologic data, and water-resources-appraisal projects. During Fiscal Years 1988 and 1989, the work was done in cooperation with 10 State agencies, 5 counties, 3 cities, 2 towns, 1 irrigation district, 2 Indian Tribes, and...

Nineteen wells were installed at nine sites in the Melton Valley area. The wells are intended to provide information on water levels in both regolith and bedrock, aquifer characteristics, and subsurface lithology. Well depths range from 24 to 86 ft for shallow wells, and from 126 to 301 ft for...

The U.S. Geological Survey, in cooperation with the United States Department of Energy, conducted a study of the Pasco basin and adjacent areas, Washington, in support of the Basalt Waste Isolation Project at the Hanford site, Washington. The purpose of the study was to develop a data set that would...

Results of a study of the effects of highway runoff on the chemical quality of water and bed sediments of a cypress wetlands and a freshwater marsh in central Florida indicate that detention of the runoff prior to release into the wetland reduces concentrations of automobile-related chemicals in the water...

Water quality of the surficial aquifer system in central Florida was evaluated at one exfiltration pipe, two ponds (detention and retention), and two swales in central Florida, representing three runoff-detention methods, to detect any effect from infiltrating highway runoff. Concentrations of major ions, metals, and nutrients in groundwater and bottom...

This report presents physical, chemical, and biological data collected at 50 sampling sites on selected streams in Chester County, Pennsylvania from 1969 to 1980. The physical data consist of air and water temperature, stream discharge, suspended sediment, pH, specific conductance, and dissolved oxygen. The chemical data consist of laboratory determinations...

Water quality and the processes that affect dissolved oxygen, nutrient (nitrogen and phosphorus species), and algal concentrations were evaluated for a 23.8-mile reach of Cedar Creek near Galesburg, west-central Illinois, during periods of warm-weather, low-flow conditions. Water quality samples were collected and stream conditions were measured over a diel (24...

The tidal reach of the Peace River in southwestern Florida extends about 26 miles upstream from Charlotte Harbor and is characterized by flow-direction reversals, low velocities, and salinity gradients that vary with freshwater inflow, tides, and wind. Flow reversals generally occur on each tide throughout most of the tidal reach,...

Pumpage from the Upper Floridan aquifer has caused a lowering of the potentiometric surface and has increased potential for saltwater intrusion into the aquifer in coastal areas of west-central Florida. Groundwater withdrawals are likely to increase because of expected population growth, especially in coastal areas. To increase the understanding of...

Hydraulic geometry, suspended-sediment, and bedload samples were collected at three sites in the upper reach of the South Fork Salmon River drainage basin from April 1985 to June 1986. Sites selected were South Fork Salmon River near Krassel Ranger Station, Buckhorn Creek, and North Fork Lick Creek. Results of the...

As of January 1, 1989, the surface-water data-collection network in Texas included 373 continuous-streamflow, 75 continuous or daily reservoir-content, 37 gage-height, 15 crest-stage partial-record, 200 data collection platform, 7 periodic discharge through range, 27 flood-hydrograph partial-record, 27 low-flow partial-record, 43 daily chemical-quality, 17 continuous-recording water quality, 87 periodic biological, 11...

This report presents selected data describing the characteristics of streams upstream from selected points on streams in the Redwood River basin. The points on the streams include outlets of subbasins of about five square miles, sewage treatment plant outlets, and U.S. Geological Survey gaging stations in the basin....

Water shortages are a chronic problem in parts of the Taunton River basin and are caused by a combination of factors. Water use in this part of the Boston metropolitan area is likely to increase during the next decade. The Massachusetts Division of Water Resources projects that about 50% of...

Hydrologic data was collected during the 1988 water year in cooperation with the Iowa Department of Natural Resources Geological Survey Bureau in the Big Spring ground-water basin located in Clayton County, Iowa. Information on precipitation, streams, and ground water was collected in the basin. Total rainfall at Big Spring was 24.08...

The hydrogeologic framework of the North Carolina Coastal Plain aquifer system consists of ten aquifers separated by nine confining units. From top to bottom the aquifers are: the surficial aquifer, Yorktown aquifer, Pungo River aquifer, Castle Hayne aquifer, Beaufort aquifer, Peedee aquifer, Black Creek aquifer, upper Cape Fear aquifer, lower...

Douglas County, Nevada encompasses 708 sq mi and has been one of the fastest growing counties in the Nation, according to the 1980 census. This rapid population growth has led to concern about the present and future impacts of development upon the groundwater. A network of 33 wells was recently...

This report presents data on the chemistry of precipitation and storm runoff that were collected during 29 storms from July 1979 through November 1980, in an urban environment in the Pennypack Creek basin, Philadelphia, Pennsylvania. Daily mean and instantaneous stream discharge data were collected at two U.S. Geological Survey gaging...
