Flood-frequency analysis for small natural streams in Georgia
Harold G. Golden, McGlone Price
1976, Open-File Report 76-511
Flood information from 104 project basins (0.1 to 20 square miles) and data available from 170 larger basins (20 to 1,500 square miles) are analyzed to provide planners and designers with relations for estimating the magnitude and frequency of flood-peak discharges on small natural streams in Georgia. More than 90...
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...
Preliminary summary of the 1976 Atlantic Margin Coring Project of the U.S. Geological Survey

The U.S. Geological Survey Atlantic Margin Coring Project, 1976, a 60-day expedition to obtain core samples by drilling beneath the floor of the Continental Shelf and Slope of the eastern United States, was carried out in July, August, and September 1976 aboard D/V GLOMAR CONCEPTION. The coring penetrated as much...
A preliminary evaluation of selected earthquake-related geologic hazards in the Kenai Lowland, Alaska
Russell G. Tysdal
1976, Open-File Report 76-270
Several major faults exist beneath the Kenai Lowland, and others may be inferred. No surface evidence was found to indicate that any of the faults have been active in Holocene time. The sparse shallow seismicity thus far recorded does not correlate with known faults, nor does it define linear trends...

Water in carbonate rocks of the Madison Group in southeastern Montana: A preliminary evaluation
W. Roger Miller
1976, Water Supply Paper 2043
The Madison Group of Mississippian age comprises, from oldest to youngest, the Lodgepole and Mission Canyon Limestones and the Charles Formation. The Madison crops out in the Bighorn and Pryor Mountains and in the mountains west of the study area. These rocks consist of cyclically deposited normal-marine carbonates and restricted-marine...

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....
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...
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...
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...

Preliminary results of preimpoundment water-quality studies in the Tioga River Basin, Pennsylvania and New York
Janice R. Ward
1976, Water-Resources Investigations Report 76-66
The Tioga River and its major tributaries were sampled monthly from September 1973 to May 1975. Water quality in the Tioga River is degraded by acid-mine drainage entering the stream near Blossburg from both strip- and deep-mined areas. The stream supports few species of aquatic life from Blossburg to its...
