Selected hydrologic data, Arkansas River basin, Pueblo and southeastern Fremont Counties, Colorado, 1975-80
Doug Cain, Patrick Edelmann
1980, Open-File Report 80-1185
Selected hydrologic data collected in 1975-80 as part of water-quality investigations by the U.S. Geological Survey in Pueblo and southeastern Fremont Counties, Colo., are presented in this report. The data, in tabular form, consist of streamflow-discharge measurements for 33 sites, channel-geometry measurements for 97 sites, traveltime data for 12 sites,...
Preliminary data describing the distribution of fluoride and silica in the water in the Ogallala aquifer on the High Plains of Texas
R.L. Bassett, S.G. Perkins, R. K. Waddell
1980, Open-File Report 80-349
The Ogallala aquifer of Texas historically has been known for elevated fluoride concentration, with many areas in excess of 4 milligrams per liter. In addition, on a regional scale, silica concentrations are also somewhat elevated, with concentrations averaging in the 40 to 50 milligrams per liter range. This aquifer provides...
Minisparker profiles from Jeffreys Ledge and adjacent areas in the western Gulf of Maine
Diane M. Eskenasy, Norman G. Bailey
1980, Open-File Report 80-320
A total of 250 kilometers of single-channel seismic-reflection data (28 minisparker profiles) were collected in the coastal waters of Massachusetts, north of and immediately south of Cape Ann, and on the western flank of Jeffreys Ledge, western Gulf of Maine, during the September 1978 cruise of the R/V ASTERIAS. The...
Potentiometric map of the Winona-Tallahatta aquifer in northwestern Mississippi, fall 1979
B. E. Wasson
1980, Open-File Report 80-598
The potentiometric map of the Winona-Tallahatta aquifer is one of a series of maps, prepared by the U.S. Geological Survey in cooperation with the Mississippi Department of Natural Resources , Bureau of Land and Water Resources, delineating the potentiometric surfaces of the major aquifers in Mississippi. In the outcrop area...
A one-dimensional, steady-state, dissolved-oxygen model and waste-load assimilation study for Duck Creek, Madison, Tipton, and Hamilton counties, Indiana
Charles G. Crawford, William G. Wilber, James G. Peters
1980, Open-File Report 80-156
The Indiana State Board of Health is developing a State water-quality plan that includes establishing limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in Duck Creek was used to develop alternatives for future waste loadings that would be compatible with Indiana stream water-quality standards...
Flood magnitude and frequency of small streams in Indiana: Preliminary estimating equations
Robert L. Gold
1980, Open-File Report 80-759
This interim report presents preliminary estimating equations developed for the ongoing study, "Flood Frequency of Small Streams in Indiana." The equations were developed by the multiple-regression technique from data collected at 57 crest-stage-gage and 15 rainfall-runoff sites in the study and from 133 streamflow stations in Indiana and 11 in...
Quality of urban runoff, Tecolote Creek drainage area, San Diego County, California
James G. Setmire, Wesley L. Bradford
1980, Water-Resources Investigations Report 80-70
The quality of storm runoff from a 9.2-square-mile urbanized watershed, Tecolote Creek, San Diego County, Calif., was studied during nine storms from September 1976 through May 1977. Specific conductance reached 2,100 micromhos and total residue concentrations reached 2,770 milligrams per liter. The chemical oxygen demand concentration in 95% of the...
Physical environment and hydrologic characteristics of coal-mining areas in Missouri
J. E. Vaill, James H. Barks
1980, Water-Resources Investigations Report 80-67
Hydrologic information for the north-central and western coal-mining regions of Missouri is needed to define the hydrologic system in these areas of major historic and planned coal development. This report describes the physical setting, climate, coal-mining practices, general hydrologic system, and the current (1980) hydrologie data base in these two...
Effects of coal mine subsidence in the Sheridan, Wyoming, area
C. Richard Dunrud, Frank W. Osterwald
1980, Professional Paper 1164
Analyses of the surface effects of past underground coal mining in the Sheridan, Wyoming, area suggest that underground mining of strippable coal deposits may damage the environment more over long periods of time than would modern surface mining, provided proper restoration procedures are followed after surface mining. Subsidence depressions and...
