Loads and yields of sediment and water-quality constituents in Kentucky streams
Rene Garcia, Angela S. Crain
1998, Open-File Report 98-411
Loads and yields of sediment and water-quality constituents were estimated for selected Kentucky streams. Streamflow, sediment, and water-quality information were collected at a network of 44 stream stations in Kentucky. Mean daily discharge was synthesized using the drainage-area ratio, regression analysis, or a combination of the two techniques. Streamflow was...
Data Quality Objectives and Criteria for Basic Information, Acceptable Uncertainty, and Quality-Assurance and Quality-Control Documentation
Gregory E. Granato, Fred G. Bank, Patricia A. Cazenas
1998, Open-File Report 98-394
The Federal Highway Administration and State transportation agencies have the responsibility of determining and minimizing the effects of highway runoff on water quality; therefore, they have been conducting an extensive program of water-quality monitoring and research during the last 25 years. The objectives and monitoring goals of highway runoff studies...
Cruise report RV Inland Surveyer Cruise IS-98; the bathymetry of Lake Tahoe, California-Nevada, August 2 through August 17, 1998, Lake Tahoe, California and Nevada
James V. Gardner, Larry A. Mayer, John Hughes-Clarke
1998, Open-File Report 98-509
The major objective of cruise IS-98 was to map the bathymetry of Lake Tahoe, California-Nevada (Fig. 1) to fulfill a commitment made during the Lake Tahoe Presidential Forum in 1997. The only existing bathymetry of Lake Tahoe, collected in 1923, was recently compiled by Rowe and Stone (1997), but the...
MAS/MILS Arc/Info point coverage for the western U.S. (excluding Hawaii)
J. Douglas Causey
1998, Open-File Report 98-512
The U.S. Geological Survey has two international and one regional digital database that contains information on mineral properties. This report describes the conversion of selected data from one of the international databases - MAS/MILS (Mineral Availability System/Mineral Industry Location System) - into a spatial data product. The MAS/MILS database, obtained...
A Review of Semivolatile and Volatile Organic Compounds in Highway Runoff and Urban Stormwater
Thomas J. Lopes, Shannon G. Dionne
1998, Open-File Report 98-409
Many studies have been conducted since 1970 to characterize concentrations of semivolatile organic compounds (SVOCs) in highway runoff and urban stormwater. To a lesser extent, studies also have characterized concentrations of volatile organic compounds (VOCs), estimated loads of SVOCs, and assessed potential impacts of these contaminants on receiving streams. This...
Water-quality characteristics of the Slate and East Rivers, Colorado, during the winter recreational season, December 1996
N.E. Spahr, J. R. Deacon
1998, Open-File Report 98-279
Periods of population influxes during winter recreation occur simultaneously with periods of extreme low flow in many Rocky Mountain areas. The ability of streams to assimilate additional nutrient loading is reduced by the low-flow conditions. Low-flow water-quality characteristics of the Slate and East Rivers, which drain the Crested Butte area,...
Hydrogeology and sources of recharge to the Buffalo and Wahpeton aquifers in the southern part of the Red River of the North drainage basin, west-central Minnesota and southeastern North Dakota
Michael Schoenberg
1998, Water-Resources Investigations Report 97-4084
Declining hydraulic heads in the Buffalo and Wahpeton aquifers are of concern to the Minnesota Department of Natural Resources and local water managers because of limited groundwater resources in the southern part of the Red River of the North drainage basin. The U.S. Geological Survey, in cooperation with the Minnesota...
Preliminary estimates of residence times and apparent ages of ground water in the Chesapeake Bay watershed, and water-quality data from a survey of springs
Michael J. Focazio, Niel Plummer, John K. Bohlke, Eurybiades Busenberg, L. Joseph Bachman, David S. Powars
1998, Water-Resources Investigations Report 97-4225
Knowledge of the residence times of the ground-water systems in Chesapeake Bay watershed helps resource managers anticipate potential delays between implementation of land-management practices and any improve-ments in river and estuary water quality. This report presents preliminary estimates of ground-water residence times and apparent ages of water in...
National water-quality assessment of the Lake Erie-Lake St. Clair Basin, Michigan, Indiana, Ohio, Pennsylvania, and New York — Environmental and hydrologic setting
G. D. Casey, Donna N. Myers, D. P. Finnegan, Michael E. Wieczorek
1998, Water-Resources Investigations Report 97-4256
The Lake Erie-Lake St. Clair Basin covers approximately 22,300 mi2 (square miles) in parts of Indiana, Michigan, Ohio, Pennsylvania, and New York. Situated in two major physiographic provinces, the Appalachian Plateaus and the Central Lowland, the basin includes varied topographic and geomorphic features that affect the hydrology. As of 1990,...
Description of piezometers installed in the Duranes well field area, Albuquerque, New Mexico
C. R. Thorn
1998, Open-File Report 98-415
Since 1993, the aquifer system in the Middle Rio Grande Basin, and particularly in the Albuquerque area, has been the focus of studies to further define the extent of the most productive parts of the aquifer and to gain a better understanding of ground-water/surface-water interactions. Twenty-one piezometers were installed during...
Ground-water flow in the surficial aquifer system and potential movement of contaminants from selected waste-disposal sites at Cecil Field Naval Air Station, Jacksonville, Florida
K. J. Halford
1998, Water-Resources Investigations Report 97-4278
As part of the Installation Restoration Program, Cecil Field Naval Air Station, Jacksonville, Florida, is considering remedialaction alternatives to control the possible movement of contaminants from sites that may discharge to the surface. This requires a quantifiable understanding of ground-water flow through the surficial aquifer system and how the system...
