Data compilation of benthic invertebrates from tributary streams in Yampa and North Platte River Basins, northwestern Colorado
L. J. Britton
1983, Open-File Report 83-140
Benthic invertebrates were collected from Trout Creek, Fish Creek, and the Williams Fork (tributaries of the Yampa River in Routt and Moffat Counties), and Little Grizzly and Grizzly Creeks (tributaries of the North Platte River in Jackson County). Stream-sampling sites were upstream and downstream from potential, existing, or historical coal-mining...
A search for stratiform massive-sulfide exploration targets in Appalachian Devonian rocks; a case study using computer-assisted attribute-coincidence mapping
Helmuth Wedow
1983, Open-File Report 83-352
The empirical model for sediment-associated, stratiform, exhalative, massive-sulfide deposits presented by D. Large in 1979 and 1980 has been redesigned to permit its use in a computer-assisted search for exploration-target areas in Devonian rocks of the Appalachian region using attribute-coincidence mapping (ACM). Some 36 gridded-data maps and selected maps derived...
Electrical and magnetic properties of rock and soil
J. H. Scott
1983, Open-File Report 83-915
Field and laboratory measurements have been made to determine the electrical conductivity, dielectric constant, and magnetic permeability of rock and soil in areas of interest in studies of electromagnetic pulse propagation. Conductivity is determined by making field measurements of apparent resisitivity at very low frequencies (0-20 cps), and interpreting the...
Ground water in the northern part of Clackamas County, Oregon
A.R. Leonard, C. A. Collins
1983, Open-File Report 80-1049
Northern Clackamas County is part of the rapidly growing Portland metropolitan area. Population of this 250-square-mile area increased about 50 percent between 1970 and 1976. The study area includes a small segment of the Willamette River alluvial valley near Canby, and extends northward to the Clackamas River and eastward to...
Selective annotated bibliography of ground-water resources, records of wells and springs, and availability of streamflow data on Indian reservations in Montana
Gary W. Levings, Melvin K. White
1983, Open-File Report 83-129
A compilation was made, for each of the seven Indian reservations in Montana, of the availability of hydrologic data. The report consists of an annotated bibliography of ground-water resources reports, selected data for wells and springs from the data bases of the U.S. Geological Survey and Montana Bureau of Mines...
Geophysical investigations in the Dhahar-Al Hajrah region, Wadi Malahah Quadrangle, southwestern Saudi Arabia
H. R. Blank
1983, Open-File Report 83-778
Crone electromagnetic, self-potential, and induced polarization surveys were conducted in the Dhahar-Al Hajrah region, southwestern Saudi Arabia, in support of geological and geochemical exploration for volcanogenic sulfide deposits. Although a previous, airborne electromagnetic survey found no anomalies in the vicinity of the ancient mines in the region, surface indications of...
Hydrologic data from the Johnson Brook phosphorus loading study, Kennebec County, Maine
Thomas J. Maloney, David R. Dominie, William J. Nichols
1983, Open-File Report 83-143
Streamflow, water quality, and precipitation data collected during the 1980 and 1981 water years are reported. The purpose was to document changes in total phosphorus loads resulting from a change in agricultural waste management practices in the Johnson Brook watershed in Maine. Streamflow data include mean-daily discharges for the period...
Analyses of native water, bottom material, elutriate samples, and dredged material from selected southern Louisiana waterways and selected areas in the Gulf of Mexico, 1979-81
Dee L. Lurry
1983, Open-File Report 82-690
The U.S. Geological Survey was requested by the U.S. Army Corps of Engineers, New Orleans District, to provide water-quality data to evaluate environmental effects of dredging activities in selected reaches of the Calcasieu River in southwestern Louisiana. Samples were collected from the upper and lower Calcasieu River between January 1980...
Water resources data, Florida, water year 1982; Volume 3A. Southwest Florida surface water
R.T. Mycyk, L.D. Fayard, W.L. Fletcher, J.K. Ogle
1983, Water Data Report FL-82-3A
Water resources data for the 1981 water year for southwest Florida consist of records of stage, discharge, and water quality of streams; elevation and water quality of lakes and reservoirs; water-levels and water quality of wells; and discharge and water quality of springs. Additional water data were collected at various...
Water resources data, Florida water year 1982, Volume 1A: Northeast Florida surface water
Water Resources Division, U.S. Geological Survey
1983, Water Data Report FL-82-1A
Water resources data for the 1982 water year in Florida consists of continuous or daily discharge for 264 streams, periodic discharge for 41 streams, miscellaneous discharge for 71 streams, continuous or daily stage for 102 streams, periodic stage for 15 streams, peak discharge for 83 streams and peak stage for...
