Flood of June 13-15, 1981, in the Blanchard River basin, northwestern Ohio
E.E. Webber
1982, Water-Resources Investigations Report 82-4044
The flood of June 13-15, 1981, in the Blanchard River basin in northwestern Ohio caused major damage in Findlay, Ottawa, and adjacent rural areas. Approximately 25 percent of Findlay and 55 percent of Ottawa were flooded. Estimated crop damage was $12 million in Hancock Country, $7 million in Wyandot Country,...
Downstream effects of reservoir releases to the Potomac River from Luke, Maryland, to Washington, D.C.
T. J. Trombley
1982, Water-Resources Investigations Report 82-4062
A digital computer flow-routing model was developed for the Potomac River in order to determine the downstream effects of flow releases from the Bloomington and Savage River Reservoirs. Both reservoirs are located above Luke, Maryland approximately 230 miles upstream from Washington, D. C. The downstream effects of reservoir releases were...
Water-quality characteristics of six small, semiarid watersheds in the Green River coal region of Colorado
John T. Turk, Randolph S. Parker
1982, Water-Resources Investigations Report 81-19
Analysis of major and trace constituents in streams flowing through six semiarid watersheds indicates that the stream chemistry is characterized by saturation with respect to common carbonate minerals (calcium, magnesium, iron, manganese, and lead). The solubility of the carbonate minerals may be a major control on the absolute and relative...
Sedimentation in the East Branch Mahoning Creek basin, Clearfield and Jefferson Counties, Pennsylvania, June 1979 to June 1980
Kim L. Wetzel
1982, Water-Resources Investigations Report 81-69
Parts of the East Branch Mahoning Creek basin, a forested area of 29.6 square miles in west-central Pennsylvania, are disturbed by farming, surface mining, unpaved haul roads, eroding reclaimed areas, and logging. Streamflow was measured and water samples collected at a site upstream from the mouth from June 1979 to...
Mineralization and other geologic factors related to the Morrison Formation in particular the northern two-thirds of the Colorado Plateau region; basic data and factor-analysis results
Robert Allen Cadigan
1982, Open-File Report 82-1130
A vanadium-mercury mineralization factor and five other significant geologic factors were determined by multivariate factor analysis of data for Morrison Formation rock samples from the Colorado Plateau region. The data presented in the report were obtained from an agglomeration of 876 samples which yielded a correlation matrix of 44 variables....
Geochemical reconnaissance for uranium occurrences in the Notch Peak intrusive area, House Range, Millard County, Utah
R. A. Cadigan, Keith Robinson
1982, Open-File Report 82-491
Samples collected from the contact metamorphic zone of the Notch Peak intrusive area, House Range, Millard County, Utah, indicate the occurrence of low-grade uranium and thorium ore. Maximum abundances in the altered mineralized rocks in the contact zone are 450 ppm uranium and 480 ppm thorium. Interpretation of factor analysis...
Occurrences of copper minerals in Alaska
1982, Open-File Report 82-1029
The following references give data, as of June 1, 1982, on localities where copper minerals have been found in Alaska. References are keyed by number to locations shown on the accompanying map. An asterisk (*) preceding a locality name indicates recorded production.In most instances the report(s) cited for each occurrence...
Water-quality assessment of White River between Lake Sequoyah and Beaver Reservoir, Washington County, Arkansas
J. E. Terry, E. E. Morris, C. T. Bryant
1982, Water-Resources Investigations Report 82-4063
The Arkansas Department of Pollution Control and Ecology and U.S. Geological Survey conducted a water quality assessment be made of the White River and, that a steady-state digital model be calibrated and used as a tool for simulating changes in nutrient loading. The city of Fayetteville 's wastewater-treatment plant is...
Quality of surface water at selected sites in the Suwannee River basin, Florida
J.E. Coffin
1982, Open-File Report 82-103
This report presents the results of analyses of water-quality samples collected from 14 surface-water sites in the Suwannee River basin in Florida from January through December 1980. The analyses of samples collected routinely included: nutrients, total organic carbon, and 5-day biochemical oxygen demand, bimonthly; and trace metals, annually. The array...
Alaska index (December 1980 - November 1981)
Mary Ann Collignon
1982, Open-File Report 82-18
In an effort to develop the oil and gas resources of the Outer Continental Shelf (OCS), the United States currently conducts a leasing program for these resources. The Secretary of the Department of the Interior (DOI) has been designated by the Outer Continental Shelf Lands Act of 1953 (43 U.S.C....
