Sedimentation in Santa Margarita Lake, San Luis Obispo County, California
G. Douglas Glysson
1977, Water-Resources Investigations Report 77-56
The 1975 storage capacity of Santa Margarita Lake in San Luis Obispo County, Calif., was 41,400 acre-feet, a decrease of 3,400 acre-feet since 1941. Usable capacity decreased from 25,800 to 23,000 acre-feet. Long-term sediment yield for the Salinas River basin upstream from the lake was estimated at 1,150 tons per...
Large landslides, composed of megabreccia, interbedded in Miocene basin deposits, southeastern Arizona
Medora Louise Hooper Krieger
1977, Professional Paper 1008
The landslides in the Kearny and El Capitan Mountain quadrangles, Pinal and Gila Counties, Ariz., are tabular or lens like masses of megabreccia enclosed in Miocene basin deposits. The megabreccias within individual slide blocks are composed of pervasively brecciated Precambrian and younger formations that remain in normal stratigraphic sequence, indicating...
Preliminary flood-frequency relations for urban streams, Metropolitan Atlanta, Georgia
Harold G. Golden
1977, Water-Resources Investigations Report 77-57
A method is presented for estimating the magnitude and frequency of floods for urban streams in metropolitan Atlanta. The method is based on adjustments to the natural stream flood-frequency and rainfall-frequency characteristics of the local area as defined by urban flood studies in other areas.The effects of urbanization on flood-peak...
Late diagenetic indicators of buried oil and gas
Terrence J. Donovan, Mary C. Dalziel
1977, Open-File Report 77-817
At least three hydrocarbon seepage mechanisms are interpreted to operate over oil and gas fields. These are: (1) effusion ofh ydrocarbons through inadequate caprocks and along faults and fractures, (2) low-molecular-weight hydrocarbons dissolved in water moving vertically through capping shales as a result of a hydrodynamic or chemical potential drive,...
Computation of backwater and discharge at width constrictions of heavily vegetated flood plains
V.R. Schneider, J.W. Board, B.E. Colson, F.N. Lee, Leroy Druffel
1977, Water-Resources Investigations Report 76-129
The U.S. Geological Survey, cooperated with the Federal Highway Administration and the State Highway Departments of Mississippi, Alabama, and Louisiana, to develop a proposed method for computing backwater and discharge at width constrictions of heavily vegetated flood plains. Data were collected at 20 single opening sites for 31 floods. Flood-plain...
Hydrologic data for the Vamoosa Aquifer, east-central Oklahoma
Joseph J. D’Lugosz, Roger G. McClaflin
1977, Open-File Report 77-487
Most of the data presented in this report were collected by the U.S. Geological Survey as part of a study of the geohydrology of the Vamoosa aquifer, in east-central Oklahoma, in cooperation with the Oklahoma Geological Survey. Some of the data listed in the tables were collected by Bingham and...
Ground-water resources and geology of Colquitt County, Georgia
E. A. Zimmerman
1977, Open-File Report 77-56
Limestone beds of Eocene, Oligocene, and lower Miocene age, called the principal artesian aquifer, are the chief source of ground water for Colquitt County. Because streams are small, undependable and relatively inaccessible to most users, ground water is the most important source for increased industrial and agricultural water use. Southeast...
Analysis of bottom material from the Willamette River, Portland Harbor, Oregon
Stuart W. McKenzie
1977, Open-File Report 77-740
The bottom material of the Willamette River, Portland Harbor, was sampled in duplicate on February 1, 1977. Results are reported on the following analyses of the material: immediate and long-term oxygen demand; particle size; percent moisture; residue, loss on ignition; and chemical....
Uranium mobility during interaction of rhyolitic glass with alkaline solutions: dissolution of glass
Robert A. Zielinski
1977, Open-File Report 77-744
This report concerns investigations designed to identify the important physical and chemical parameters influencing the rate of release of uranium from glass shards of rhyolitic air-fall ash. Oxidizing, silica undersaturated, alkaline solutions are eluted through a column of rhyolitic glass shards at a carefully controlled temperature, pressure, and flow rate....
Mineral resources of the Sheep Mountain Wilderness study area and the Cucamonga Wilderness and additions, Los Angeles and San Bernardino counties, California
James G. Evans, Leroy Pankraatz, James Ridenour, Steven W. Schmauch, Nicholas T. Zilka
1977, Open-File Report 77-251
A mineral survey of the Sheep Mountain Wilderness study area and Cucamonga Wilderness area and additions by the U.S. Geological Survey and Bureau of Mines in 1975 covered about 66,500 acres (26,500 ha) of the San Bernardino and Angeles National Forests in southern California. The two study areas are separated...
