Geochemical map of the Guadalupe Escarpment Wilderness Study Area, Eddy County, New Mexico
T.D. Light, J. A. Domenico, S. M. Smith
1985, Miscellaneous Field Studies Map 1560-B
During 1982, the U.S. Geological Survey and the U.S. Bureau of Mines conducted field investigations to evaluate the mineral resource potential of the Guadalupe Escarpment Wilderness Study Area. Field studies included geologic mapping, geochemical sampling, and a survey of known mines, prospects, and mineralized zones. This map presents the results...
Delineation of the outcrop of the Edwards Aquifer hydrologically associated with Barton Springs in the Austin area, Texas
Ann F. Ardis, D.L. Slagle, Fred R. Snyder
1985, Open-File Report 85-643

Effects of storm-water runoff on an urban lake, Lake Ellyn at Glen Ellyn, Illinois
Robert G. Striegl
1985, Open-File Report 84-603
Detention of urban runoff was observed to have physical, chemical, and biological effects on a small lake located near Chicago, Illinois. Accumulated bottom sediments reduce lake storage and have comparatively high concentrations of metals and organic compounds. Concentrations of many constituents dissolved in the lake water are seasonally cyclic, with...
Seismicity map of the State of Wyoming
B.G. Reagor, C. W. Stover, S. T. Algermissen
1985, Miscellaneous Field Studies Map 1798
The data shown on this map and listed in table 1 are for earthquakes that were originally included in a study of seismic risk in the United States (Algermissen, 1969). This data file has been recompiled and updated through 1981. Some revisions of epicenters and intensities in the original file...
Water-quality characteristics of streams in the Piceance Creek and Yellow Creek drainage basins, northwestern Colorado, water years 1977-81
R.L. Tobin, H.E. Stranathan, K.J. Covay
1985, Water-Resources Investigations Report 84-4261
Physical and chemical data for streams in the Piceance Creek and Yellow Creek drainage basins, Colorado collected during the 1977-81 water years are summarized. Stream temperatures ranged from -0.5 to 35.0 degrees Celsius and were warmest near the downstream reaches of Piceance and Yellow Creeks. Minimum concentrations of dissolved oxygen...
Hydrology of major estuaries and sounds of North Carolina
G. L. Giese, Hugh B. Wilder, Garald G. Parker Jr.
1985, Water Supply Paper 2221
Hydrology-related problems associated with North Carolina 's major estuaries and sounds include contamination of some estuaries with municipal and industrial wastes and drainage from adjacent, intensively farmed areas, and nuisance-level algal blooms. In addition, there is excessive shoaling in some navigation channels, salt-water intrusion into usually fresh estuarine reaches, too...
