Water resources of Lincoln County coastal area, Oregon
F. J. Frank, Antonius Laenen
1976, Water-Resources Investigations Report 76-90
The Lincoln County coastal area is underlain by Tertiary volcanic and sedimentary rocks of low permeability that store only a small volume of the annual precipitation which averages 68 inches (1,730 millimeters). Consequently, the Tertiary units yield small quantities of water to wells and furnish little ground-water discharge to maintain...
Computer applications for step-backwater and floodway analyses
James O. Shearman
1976, Open-File Report 76-499
A computer program which can be used to computer water-surface profiles for gradually varied, subcritical flow is described. Profiles are computed by the standard step-backwater method. Water-surface profiles may be obtained for both existing stream conditions and for stream conditions as modified by encroachment. The user may specify encroachment patterns...
Buried aquifers in the Brooten-Belgrade and Lake Emily areas, west-central Minnesota--Factors related to developing water for irrigation
R. J. Wolf
1976, Water-Resources Investigations Report 76-100
Irrigation has given a substantial boost to the economy in the Brooten-Belgrade and Lake Emily areas of Minnesota. The surficial outwash aquifer is capable of yielding sufficient quantities of water for irrigation over half of its area; the remaining part may be supplied by deep aquifers. Buried glacial outwash and...
Geology and ore deposits of the McDermitt Caldera, Nevada-Oregon
James J. Rytuba
1976, Open-File Report 76-535
The McDermitt caldera is a Miocene collapse structure along the Nevada-Oregon border. The oval-shaped caldera is bounded by arcuate normal faults on the north and south and by rhyolite ring domes on the west. Precollapse ash-flow tuffs exposed within the south caldera rim consist of three cooling units and are...
A preliminary evaluation of selected earthquake-related geologic hazards in the Kenai Lowland, Alaska
Russell G. Tysdal
1976, Open-File Report 76-270
Several major faults exist beneath the Kenai Lowland, and others may be inferred. No surface evidence was found to indicate that any of the faults have been active in Holocene time. The sparse shallow seismicity thus far recorded does not correlate with known faults, nor does it define linear trends...

Physical, chemical, and biological aspects of subsurface organic waste injection near Wilmington, North Carolina
J.A. Leenheer, Ronald L. Malcolm, W.R. White
1976, Professional Paper 987
From May 1968 to December 1972, an industrial organic waste was injected at rates of 100 to 200 gallons per minute (6.3 to 12.6 litres per second) into a sand, gravel, and limestone aquifer of Late Cretaceous age by Hercules Inc. located near Wilmington, North Carolina. This report presents both...
Preliminary results of preimpoundment water-quality studies in the Tioga River Basin, Pennsylvania and New York
Janice R. Ward
1976, Water-Resources Investigations Report 76-66
The Tioga River and its major tributaries were sampled monthly from September 1973 to May 1975. Water quality in the Tioga River is degraded by acid-mine drainage entering the stream near Blossburg from both strip- and deep-mined areas. The stream supports few species of aquatic life from Blossburg to its...

Index to water resources data for Illinois
D.E. Winget
1976, Water-Resources Investigations Report 76-87
This index to water resources data for Illinois includes 1,275 sites where surface-water and ground-water data were collected through December 31, 1975. The index is the first comprehensive tabulation of data collected in Illinois by the U.S. Geological Survey; data collection began in 1903. Information included are the county code,...

Preimpoundment water quality of Raystown Branch Juniata River and six tributary streams, south-central Pennsylvania
Donald R. Williams
1976, Water-Resources Investigations Report 76-57
The Raystown Branch Juniata River watershed, which is the main water source for Raystown Lake, is a 960-square-mile (2,490 square kilometres) drainage basin in south-central Pennsylvania. Preimpoundment water-quality data were collected on the Raystown Branch and six tributary st.reams in the basin. Specific conductance values varied inversely with water discharge....
Application of the U.S. Geological Survey rainfall-runoff simulation model to improve flood-frequency estimates on small Tennessee streams
Herman C. Wibben
1976, Water-Resources Investigations Report 76-120
The U.S. Geological Survey rainfall-runoff simulation model was used in conjunction with National Weather Service climatological data to improve flood-frequency estimates for 52 small drainage basins in Tennessee. The basins range in size from 0.17 to 64 square miles (0.44 to 166 square kilometers) and are distributed throughout the State....

Effects of urbanization on flood characteristics in Nashville-Davidson County, Tennessee
Herman C. Wibben
1976, Water-Resources Investigations Report 76-121
Streamflow data from 14 basins in Davidson County, Tenn., were extended in time by use of a digital model of the hydrologic system. The basins ranged in size from 1.58 to 64.0 square miles and ranged in extent of manmade impervious cover from 3 to 37 percent. The flood-frequency characteristics...
