Estimating the gas and dye quantities for modified tracer technique measurements of stream reaeration coefficients
R. E. Rathbun
1979, Water-Resources Investigations Report 79-27
Measuring the reaeration coefficient of a stream with a modified tracer technique has been accomplished by injecting either ethylene or ethylene and propane together and a rhodamine-WT dye solution into the stream. The movement of the tracers through the stream reach after injection is described by a one-dimensional diffusion equation....
The Yampa River basin, Colorado and Wyoming : a preview to expanded coal-resource development and its impacts on regional water resources
Timothy Doak Steele, D. P. Bauer, D.A. Wentz, J. W. Warner
1979, Water-Resources Investigations Report 78-126
Expanded coal production and conversion in the Yampa River basin , Colorado and Wyoming, may have substantial impacts on water resources, environmental amenities, and socioeconomic conditions. Preliminary results of a 3-year basin assessment by the U.S. Geological Survey are given for evaluation of surface- and ground-water resources using available data,...
Map showing ground-water conditions in the Virgin River, Grand Wash, and Shivwits areas, Mohave County, Arizona, 1976
G. W. Levings, C. D. Farrar
1979, Water-Resources Investigations Report 79-57
The Virgin River, Grand Wash, and Shivwits areas include about 3 ,250 square miles in northwestern Arizona. Ground water is obtained mainly from the alluvium, conglomerate, and basalt; however, several other formations yield small amounts of water to some wells. In the Virgin River area, most wells are less than...
Hydrologic evaluation of the Alton reclamation-study site, Alton coal field, Utah
G. W. Sandberg
1979, Open-File Report 79-346
This investigation was conducted from July 1974 to September 1977 to define general hydrologic conditions at a reclamation-study site in the Alton coal field near Kanab, Utah. The average annual streamflow through the area was less than 600 acre-feet (0.7 cubic hectometer), and the water carried little sediment except during...
The Citronelle aquifers in Mississippi
E. H. Boswell
1979, Water-Resources Investigations Report 78-131
The Citronelle aquifers consist of sand and gravel of Pliocene age that forms a discontinuous outcrop area of about 6,000 square miles in southern Mississippi. The beds dip to the south at an average rate of about 6 feet per mile. The unconfined aquifers are used mostly for domestic and...
Chemical quality of ground water on Cape Cod, Massachusetts
M. H. Frimpter, F. B. Gay
1979, Water-Resources Investigations Report 79-65
Cape Cod is a 440 square mile hook-shaped peninsula which extends 40 miles into the Atlantic. Freshwater in Pleistocene sand and gravel deposits is the source of supply for nearly 100 municipal and thousands of private domestic wells. Most ground water on Cape Cod is of good chemical quality for...
Directory of member organizations of the National Water Data Exchange (NAWDEX)
Melvin D. Edwards, Janet M. Nokes
1979, Open-File Report 79-1075
The National Water Data Exchange (NAWDEX) is a national confederation of water-oriented organizations working together to improve access to water data. It consists of member organizations from all sectors of the water-data community. This Directory provides the names, addresses, and telephone numbers of all NAWDEX member organizations and their designated...

Richard A. Fontaine
1979, Open-File Report 78-556-C
The report contains drainage-area values for: lakes and ponds included in the Maine Informational Display Analysis System (MIDAS) File 906-Z, streams that drain an area greater than 25 mi2, dams, and hydrologic data collection sites. Supplemental information in the report includes State and Federal location systems used to identify these...
