A survey for mallard pairs in the Atlantic flyway
H.W. Heusmann, John R. Sauer
1997, Journal of Wildlife Management (61) 1191-1198
During 1989-1992, spring surveys of randomly selected, 1-km2 plots, stratified by physiographic strata, were conducted in the Atlantic flyway from New Hampshire to Virginia, to estimate mallard (Anas platyrhynchos) pairs. All potential waterfowl habitat in each plot was checked by ground crews. The adjusted mean mallard pair estimate over the...
Survival rates of American woodcock wintering in the Georgia Piedmont
David G. Krementz, James Berdeen
1997, Journal of Wildlife Management (61) 1328-1332
We estimated survival rates of wintering American woodcock (Scolopax minor). We found no age- or sex-specific differences in period survival rates. The survival rate for the period 25 December 1994-7 February 1995 for all age and sex classes combined (0.72) was not different from a similarly derived estimate for woodcock...

Vulnerability of ground water to atrazine leaching in Kent County, Michigan
D. J. Holtschlag, C. L. Luukkonen
1997, Water-Resources Investigations Report 96-4198
A steady-state model of pesticide leaching through the unsaturated zone was used with readily available hydrologic, lithologic, and pesticide characteristics to estimate the vulnerability of the near-surface aquifer to atrazine contamination from non-point sources in Kent County, Michigan. The modelcomputed fraction of atrazine remaining at the water table, RM, was...
Gravity data of Nevada
David A. Ponce
1997, Data Series 42
Gravity data for the entire state of Nevada and adjacent parts of California, Utah, and Arizona are available on this CD-ROM. About 80,000 gravity stations were compiled primarily from the National Geophysical Data Center and the U.S. Geological Survey. Gravity data was reduced to the Geodetic Reference System of 1967...
3-D reservoir characterization of the House Creek oil field, Powder River Basin, Wyoming
Debra K. Higley, Michael P. Pantea, Roger M. Slatt
1997, Data Series 33
This CD-ROM is intended to serve a broad audience. An important purpose is to explain geologic and geochemical factors that control petroleum production from the House Creek Field. This information may serve as an analog for other marine-ridge sandstone reservoirs. The 3-D slide and movie images are tied to explanations...
What are volcano hazards?
Bobbie Myers, Steven R. Brantley, Peter R. Stauffer, James W. Hendley II
1997, Fact Sheet 002-97
Volcanoes give rise to numerous geologic and hydrologic hazards. U.S. Geological Survey (USGS) scientists are assessing hazards at many of the almost 70 active and potentially active volcanoes in the United States. They are closely monitoring activity at the most dangerous of these volcanoes and are prepared to issue warnings...
Effects of uranium-mining releases on ground-water quality in the Puerco River Basin, Arizona and New Mexico
Peter C. Van Metre, Laurie Wirt, T. J. Lopes, S.A. Ferguson
1997, Water Supply Paper 2476
Shallow ground water beneath the Puerco River of Arizona and New Mexico was studied to determine the effects of uranium-mining releases on water quality. Ground-water samples collected from 1989 to 1991 indicate that concentrations of dissolved uranium have decreased. Most samples from the alluvial aquifer downstream from Gallup, New Mexico,...

1997, Water-Resources Investigations Report 95-4143
The U.S. Geological Survey and the Pennsylvania Department of Environmental Protection conducted a study from 1984 to 1990 to determine theeffects of the implementation and practice of nutrient management [an agricultural best-management practice (BMP)] on the quality of surface runoff and ground water at a 55-acre crop and...
Precipitation-runoff and streamflow-routing models for the Willamette River basin, Oregon
Antonius Laenen, John C. Risley
1997, Water-Resources Investigations Report 95-4284
Precipitation-runoff and streamflow-routing models were constructed and assessed as part of a water-quality study of the Willamette River Basin. The study was a cooperative effort between the U.S. Geological Survey (USGS) and the Oregon Department of Environmental Quality (ODEQ) and was coordinated with the USGS National Water-Quality Assessment (NAWQA) study...
