Water quality of Somerville Lake, south-central Texas
Emma McPherson, H.B. Mendieta
1983, Water-Resources Investigations Report 82-4124
Somerville Lake in south-central Texas is a shallow lake, with a mean depth of 14 feet. The maximum depth of the submerged channel of Yegua Creek is usually less than 35 feet and in most areas of the lake the depth is less than 10 feet. Several factors including thermal circulation...
Ground-water quality in the western Snake River basin, Swan Falls to Glenns Ferry, Idaho
D. J. Parliman
1983, Water-Resources Investigations Report 83-4062
Water-quality data were collected from 92 wells in the western Snake River basin, Swan Falls to Glenns Ferry, Idaho. Current data were compiled with pre-1980 data from 116 wells to define water-quality conditions in major aquifers. Factors affecting water quality are composition of aquifer materials, water temperature, and source of...
Meteorological, water-temperature, and discharge data for the Mattole River basin, Humboldt County, California
R.D. Noble, Alan P. Jackman
1983, Water-Resources Investigations Report 78-81
To overcome a major difficulty in the testing of the validity of river-temperature models - the lack of adequate precise synoptic data for an entire river basin - synoptic meteorologic, water-temperature, and discharge data were obtained in the Mattole River Basin in northern California during the period June 10 through...
Reconnaissance of surface-water resources in the Kobuk River basin, Alaska, 1979-80
J.M. Childers, D.R. Kernodle
1983, Water-Resources Investigations Report 83-4027
Surface water data were collected at selected sites in the Kobuk River Basin in northwest Alaska in August 1979 and April 1980. In August 1979, frequent heavy rains caused abnormally high flows in the basin; unit runoff values, computed from discharge measurements at 25 sites, ranged from 0.08 to 12.2...
Chloride concentrations in the coastal margin of the Floridan Aquifer, southwest Florida
K.W. Causseaux, J. D. Fretwell
1983, Water-Resources Investigations Report 82-4070
The Floridan aquifer is the principal source of freshwater supply in southwest Florida. The freshwater part of the aquifer is underlain by saltwater in lower formations and is bounded on the west by saltwater in the coastal parts of the aquifer. A zone of mixing lies between the saltwater and...
Aeromagnetic map of the Powderhorn wilderness study area and Cannibal Plateau Roadless Area, Gunnison and Hinsdale counties, Colorado
R.A. Martin, William N. Sharp
1983, Miscellaneous Field Studies Map 1483-B
The Powderhorn Wilderness Study Area (51,000 acres or 20,640 hectares) and the contiguous Cannibal Plateau Roadless Area (29,500 acres or 11,959 hectares) are on the Gunnison County-Hinsdale County boundary, approximately 50mi (80 km) southwest of Gunnison and a few miles east of Lake City, Colo. Part of the area has...
Mineral resource potential map of the Raywood Flat Roadless Areas, Riverside and San Bernardino counties, California
Jonathan C. Matti, Brett F. Cox, Stephen R. Iverson
1983, Miscellaneous Field Studies Map 1563-A
Geologic, geochemical, and geophysical studies within the Raywood "Flat Roadless Areas, together with an investigation of mines and prospects within the further planning area, resulted in (1) identification of nonmetallic mineral resources at a marble mine in the further planning area and (2) recognition of a small area in the...
Rainbow filtering for terrain correcting airborne gravity
D. L. Campbell
1983, Open-File Report 83-385
In 1933, H. Rainbow derived a digital filter that relates horizontal gravity gradient to slope of the causative body. The Rainbow filter helps point to techniques for making topographic corrections to airborne gravity data....
Map showing distribution of small-scale deformation structures in a part of the upper coastal plain of South Carolina and adjacent Georgia
R. C. McDowell, B. B. Houser
1983, Miscellaneous Field Studies Map 1538
As a contribution to the assessment of neotectonics in the area of the Upper Coastal Plain of South Carolina, field traverses were made between Columbia, S.C., and Augusta, Ga., in 1975 and early 1976 in order to locate and describe small-scale deformation structures within exposed Coastal Plain rocks. The study...
Analytical results for 544 water samples collected in the Attean Quartz Monzonite in the vicinity of Jackman, Maine
W. H. Ficklin, G.A. Nowlan, D. J. Preston
1983, Open-File Report 83-831
Water samples were collected in the vicinity of Jackman, Maine as a part of the study of the relationship of dissolved constituents in water to the sediments subjacent to the water. Each sample was analyzed for specific conductance, alkalinity, acidity, pH, fluoride, chloride, sulfate, phosphate, nitrate, sodium, potassium, calcium, magnesium,...
