Highlights of the 1983 Federal-state cooperative water resources program
B.K. Gilbert, T.J. Buchanan
1983, Open-File Report 83-763
The U.S. Geological Survey Federal-State Cooperative Water Resources Program in fiscal year 1983 continued to concentrate on investigations of highest priority to the Nation. Hydrologic data collection and interpretive studies were underway in every State, Puerto Rico, and several U.S. territories with focus on such current concerns as ground-water contamination,...
Hydrologic data for the drainage basins of Chatfield and Cherry Creek Lakes, Denver metropolitan area, Colorado
J. W. Gibbs, L.M. Arnold, R.L. Reed
1983, Open-File Report 83-857
Chatfield and Cherry Creek Lakes are flood control lakes constructed by the U.S. Army Corps of Engineers and leased to the Colorado Division of Parks and Recreation. Both lakes are in the Denver metropolitan area and provide a variety of recreational activities, including boating, camping, fishing, picnicking, and swimming. The...
Ground-water exploration in the South Kohala district, Hawaii County, Hawaii, using vertical electrical sounding
James P. Kauahikaua, Dallas B. Jackson
1983, Open-File Report 83-67
Ten deep electrical resistivity soundings were completed across the island of Hawai?i near the town of Waimea in an effort to locate high-level, dike-impounded water. The resistivity data did not support the existence of a high-level water occurrence. Instead, the data show that a thick basal fresh-water lens underlies the...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: September 1983
John B. Townshend, J.E. Papp, E.A. Sauter, L.Y. Torrence, P.A. Franklin
1983, Open-File Report 83-300-I
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Analyses and descriptions of geochemical samples from the Rich Mountain Roadless Area, Fannin and Gilmer counties, Georgia
C.M. Sears, M. P. Foose, G.W. Day, M.S. Ericksen
1983, Open-File Report 83-658
Semi-quantitative spectrographic analyses for 31 elements on rock, soil, fine-grained stream sediment, bulk stream sediment, and panned stream sediment samples collected in the Rich Mountain Roadless Area, Fannin and Gilmer Counties, Georgia, are reported here. Atomic absorption analyses for gold and fluorometric analyses for uranium are also reported. Brief descriptions...
Geologic interpretation of geophysical data for the Wadi al Jarir and Al Jurdhawiyah quadrangles, sheets 25/42 C and D, Kingdom of Saudi Arabia
M. Dean Kleinkopf, J. C. Cole
1983, Open-File Report 83-371
Interpretations of aeromagnetic and gravity data made in support of geologic mapping clearly outline the near-surface shape of Proterozoic granitic units in the Wadi al Jarir (25/42 C) and Al Jurdhawiyah (25/42 D) 1:100,000-scale quadrangles of the northern part of the Arabian Shield. The aeromagnetic data show marked correlation with...
Strata-bound, silver-bearing iron, lead, and zinc sulfide deposits in Silurian and Ordovician rocks of allochthonous terranes, Nevada and northern Mexico
Keith Brindley Ketner
1983, Open-File Report 83-792
Allochthonous terranes in northern Nevada contain strata-bound sulfide deposits at two horizons in Silurian and Ordovician siliceous sedimentary rocks. The most intensively mineralized horizon and most extensive deposit is at the base of the Silurian. Another less extensive deposit is in the lower Middle Ordovician. Spectrographic analyses of gossan from...
Bryozoan fauna of the Upper Clays Ferry, Kope, and Lower Fairview formations (Edenian, Upper Ordovician) at Moffett Road, northern Kentucky
Olgerts L. Karklins
1983, Open-File Report 83-21
The geology, water movement, and sediment characteristics in the upstream part of the Spring River basin have been appraised, to assist the U.S. EPA in their study of dioxin contamination in the area. The U.S. Environmental Protection Agency has confirmed that the dioxin compound, TCDD (2,3,7 ,8-tetrachlorodibenzo-p-dioxin), is present in...
Habitat Suitability Index Models: Fisher
Arthur W. Allen
1983, FWS/OBS 82/10.45
The fisher (Martes pennanti) is the largest member of its genus and is found only i n North America (Powell 1982). Within the contiguous United States, indigenous and reintroduced populations presently inhabit portions of the Appalachian Mountains from New England south to West Virginia in the east; northern Wisconsin, Minnesota,...
Water resources of Manatee County, Florida
David P. Brown
1983, Water-Resources Investigations Report 81-74
Rapid development of Manatee County in southwest Florida is creating water-resource problems. This report presents an evaluation of the water resources and potential effects of water-resource developments. Most streams in the county have small drainage basins and minimal flow. Streamflow is variable with the base flow occurring from November to...
