Revised preliminary geologic map of the Rifle Quadrangle, Garfield County, Colorado
R. R. Shroba, R. B. Scott
1997, Open-File Report 97-852
The Rifle quadrangle extends from the Grand Hogback monocline into the southeastern part of the Piceance basin. In the northeastern part of the map area, the Wasatch Formation is nearly vertical, and over a distance of about 1 km, the dip decreases sharply from about 70-85o to about 15-30o toward...
The Areal Extent of Continuous Type Gas Accumulations in Lower Silurian Clinton Sands and Medina Group Sandstones of the Appalachian Basin and the Environments Affected by Their Development
C. J. Wandrey, Robert T. Ryder, Vito F. Nuccio, Kerry L. Aggen
1997, Open-File Report 97-272
In order to best preserve and manage our energy and natural resources we must understand the relationships between these resources and the impacts of their development. To further this understanding the U.S. Geological Survey is studying unconventional continuous-type and, to a lesser extent, conventional oil and gas accumulations and the...
Biostratigraphic data for the Cretaceous marine sediments in the USGS-St. George no. 1 core (DOR-211), Dorchester County, South Carolina
Jean M. Self-Trail, Gregory S. Gohn
1997, Open-File Report 96-684
The USGS-St. George corehole was drilled for the U.S. Geological Survey (USGS) by a commercial drilling company during 1982. The corehole is located within the Coastal Plain Province in northern Dorchester County, South Carolina, about three miles southeast of the town of St. George near the village of Byrd (fig....
U.S. Geological Survey coal quality (COALQUAL) database: Version 2.0
L. J. Bragg, J. K. Oman, S.J. Tewalt, C.L. Oman, N. H. Rega, P. M. Washington, R. B. Finkelman
1997, Open-File Report 97-134
The USGS Coal Quality database is an interactive, computerized component of the NCRDS. It contains comprehensive analyses of more than 13,000 samples of coal and associated rocks from every major coal-bearing basin and coal bed in the U.S. The data in the coal quality database represent analyses of the coal...
Water and salt balance of Great Salt Lake, Utah, and simulation of water and salt movement through the causeway
Steven R. Wold, Blakemore E. Thomas, Kidd M. Waddell
1997, Water Supply Paper 2450
The water and salt balance of Great Salt Lake primarily depends on the amount of inflow from tributary streams and the conveyance properties of a causeway constructed during 1957-59 that divides the lake into the south and north parts. The conveyance properties of the causeway originally included two culverts, each...
Agricultural land-use classification using landsat imagery data, and estimates of irrigation water use in Gooding, Jerome, Lincoln, and Minidoka counties, 1992 water year, Upper Snake River basin, Idaho and western Wyoming
Molly A. Maupin
1997, Water-Resources Investigations Report 97-4115
As part of the U.S. Geological Survey's National Water-Quality Assessment Program in the upper Snake River Basin study unit, land- and water-use data were used to describe activities that have potential effects on water quality, including biological conditions, in the basin. Land-use maps and estimates of water use by irrigated...
Preliminary geologic map of the Little Piute Mountains, California: A digital database
Keith A. Howard, Michael L. Dennis, Karl Karlstrom, Geoffrey A. Phelps
1997, Open-File Report 97-693
The Little Piute Mountains Digital database contains digital geologic and geographic information for the study area. The geology was mapped at a scale of 1:8,000, and the topographic information was input from the Little Piute Mountains, CA 1:24,000 quadrangle. The accuracy of the spatial information is limited to the input...
Water-quality assessment of the Trinity River Basin, Texas — Nutrients and pesticides in the watersheds of Richland and Chambers Creeks, 1993-95
L. F. Land
1997, Water-Resources Investigations Report 97-4132
A study of nutrients and pesticides was conducted during February-August 1995 in the west-central part of the Trinity River Basin, where land commonly is used for growing crops. Water and bed-sediment samples were collected at 8 small reservoir sites in the headwaters (known as Natural Resources Conservation Service reservoirs), at...
Characteristics of fish assemblages and related environmental variables for streams of the upper Snake River basin, Idaho and western Wyoming, 1993-95
Terry R. Maret
1997, Water-Resources Investigations Report 97-4087
Fish assemblages and environmental variables were evaluated for 30 first- through seventh-order streams in the upper Snake River Basin, Idaho and western Wyoming. Data were collected as part of the National Water-Quality Assessment Program to characterize aquatic biota and associated habitats in surface water. Sampling sites represented major stream types...
Hydrologic and water-quality data related to the occurrence of arsenic for areas along the Madison and Upper Missouri Rivers, southwestern and west-central Montana
L.K. Tuck, D.M. Dutton, D. A. Nimick
1997, Open-File Report 97-203
Geothermal waters in Yellowstone National Park contribute large quantities of arsenic to the headwaters of the Madison River. Water in some Quaternary and Tertiary valley-fill deposits along the Madison and upper Missouri Rivers also is locally enriched in arsenic. Arsenic in surface and ground water in these...
Sub-crop geologic map of pre-Tertiary rocks in the Yucca Flat and northern Frenchman Flat areas, Nevada Test Site, southern Nevada
J. C. Cole, Anita G. Harris, Ronald R. Wahl
1997, Open-File Report 97-678
This map displays interpreted structural and stratigraphic relations among the Paleozoic and older rocks of the Nevada Test Site region beneath the Miocene volcanic rocks and younger alluvium in the Yucca Flat and northern Frenchman Flat basins. These interpretations are based on a comprehensive examination and review of data for...
Techniques for estimating peak flow on small streams in Minnesota
D. L. Lorenz, G.H. Carlson, C. A. Sanocki
1997, Water-Resources Investigations Report 97-4249
Two statistically-derived techniques, regional regression equation and region of influence regression, that estimate peak flow on small, ungaged streams in Minnesota were developed. Both techniques relate physical and climatic characteristics to peak flow for 2-, 5-, 10-, 25-, 50-, and 100-year recurrence intervals. Regional regression equations were developed for each recurrence...
