The effects of ground-water development on the water supply in the Post Headquarters area, White Sands Missile Range, New Mexico
T. E. Kelly, Glenn A. Hearne
1976, Open-File Report 76-277
Water-level declines in the Post Headquarters area, White Sands Missile Range, N. Mex., have been accompanied by slight but progressive increases in the concentration of dissolved solids in water withdrawn from the aquifer. Projected water-level declines through 1996 are estimated from a digital simulation model to not exceed 200 feet...
Geology and ore deposits of the McDermitt Caldera, Nevada-Oregon
James J. Rytuba
1976, Open-File Report 76-535
The McDermitt caldera is a Miocene collapse structure along the Nevada-Oregon border. The oval-shaped caldera is bounded by arcuate normal faults on the north and south and by rhyolite ring domes on the west. Precollapse ash-flow tuffs exposed within the south caldera rim consist of three cooling units and are...
Limnological investigation of six lakes in southeast Alaska
George A. McCoy, William W. Wiggins, Artwin E. Schmidt
1976, Water-Resources Investigations Report 76-122
Limnological data were collected from six lakes in southeast Alaska in 1974. The data include concentrations of major inorganic constituents, nutrients, selected trace metals, total organic carbon, and chlorophyll. Vertical profiles of specific conductance, temperature, dissolved-oxygen saturation, and pH were drawn. With the exception of Redoubt Lake, all of the...
Computer applications for step-backwater and floodway analyses
James O. Shearman
1976, Open-File Report 76-499
A computer program which can be used to computer water-surface profiles for gradually varied, subcritical flow is described. Profiles are computed by the standard step-backwater method. Water-surface profiles may be obtained for both existing stream conditions and for stream conditions as modified by encroachment. The user may specify encroachment patterns...
Water-quality data for the Eagle River valley in the vicinity of Eagle and Vail, West-central Colorado
T.F. Giles, Robert E. Brogden
1976, Open-File Report 76-812
Water-quality data were collected by the U.S. Geological Survey in the Eagle River valley, Colo., during 1976. Forty-nine ground-water samples from wells and springs were collected and analyzed during the study. Eight surface-water samples were analyzed. All the water samples were analyzed for major cations and anions, selenium, and arsenic....
Hydrologic data for Little Elm Creek, Trinity River basin, Texas, 1976
R.M. Slade Jr., T.H. Hays, C.T. Schoultz
1976, Open-File Report 78-100
This report contains rainfall, runoff, and storage data collected during the 1976 water year for a 75.5 sq mi area above the stream-gaging station Little Elm Creek near Aubrey, Texas. Floodflows from 35.7 sq mi of the area are regulated by 16 floodwater-retarding structures constructed by the Soil Conservation Service....
Probable maximum flood at Lake Chippewa near Winter, Wisconsin
William R. Krug
1976, Open-File Report 76-800
The probable maximum flood was computed for Lake Chippewa, Wisconsin, and routed through the lake to determine maximum lake stage. The peak discharge of the probable maximum flood at Lake Chippewa was computed to be about 75,000 cubic feet per second, primarily caused by rainfall on the lake. A secondary...
Computer simulation model of the Pleistocene valley-fill aquifer in southwestern Essex and southeastern Morris counties, New Jersey
Harold Meisler
1976, Water-Resources Investigations Report 76-25
A finite-difference digital computer model was developed to simulate a buried valley-fill aquifer consisting of outwash sand and gravel deposited in a series of valleys cut into bedrock of Triassic age. Till, clay, silt, and muck function as an overlying semiconfining layer. The bedrock which is represented as an unconfined...
