A geochemical survey was conducted in the Mount Henry Roadless Area, Kootenai National Forest, Lincoln County, Mont. by the U.S. Geological Survey during the summer of 1981. The sampling and analytical programs were designed to locate mineralized zones in outcrops or in rocks buried at shallow depth. The geochemical results should...
Habitat Suitability Index Models: The Arizona guild and layers of habitat models
Henry L. Short
1984, FWS/OBS 82/10.70
This document is part of the Habitat Suitability Index Models Series, which provides habitat information useful for impact assessment and habitat management. Both of the models described in this report are based on the significant association of Wildlife species with vegetation structure. The models compare the structure in the study...
Water-resources investigations of the U.S. Geological Survey in Montana, October 1983 through September 1984
R.S. Roberts
1984, Open-File Report 84-435
U.S. Geological Survey investigations of the water resources of Montana are described. Hydrologic information and knowledge of the water resources are gained and disseminated principally by programs of (1) collecting hydrologic data on a continuing basis , (2) conducting water-resources appraisals of surface and ground water, (3) conducting supportive research...
Phosphate rock resources of the United States
James Bachelder Cathcart, Richard Porter Sheldon, Robert A. Gulbrandsen
1984, Circular 888
In 1980, the United States produced about 54 million tons of phosphate rock, or about 40 percent of the world's production, of which a substantial amount was exported, both as phosphate rock and as chemical fertilizer. During the last decade, predictions have been made that easily ruinable, low-cost reserves of...
Sediment transport by irrigation return flows in four small drains within the DID-18 drainage of the Sulphur Creek basin, Yakima County, Washington, April 1979 to October 1981
P. R. Boucher
1984, Water-Resources Investigations Report 83-4167
Suspended sediment, water discharges, and water temperatures were monitored in four small drains in the DID-18 basin of the Sulphur Creek basin, a tributary to the Yakima River, Washington. Water outflow, inflow, and miscellaneous sites were also monitored. The information was used to evaluate the effectiveness of management practices in...
Oregon ground-water quality and its relation to hydrogeologic factors — A statistical approach
T. L. Miller, J. B. Gonthier
1984, Water-Resources Investigations Report 84-4242
An appraisal of Oregon ground-water quality was made using existing data accessible through the U.S. Geological Survey computer system. The data available for about 1,000 sites were separated by aquifer units and hydrologic units. Selected statistical moments were described for 19 constituents including major ions. About 96 percent of all...
