Occurrence and distribution of molybdenum in the surface water of Colorado
Paul Thomas Voegeli, Robert Ugstad King
1969, Water Supply Paper 1535-N
Molybdenum was detected in 89 percent of the samples collected from all the principal Colorado streams and their chief tributaries and from a few reservoirs and lakes. Amounts detected ranged from 1 to 3,800 micrograms per liter. The greatest amounts of molybdenum detected were in samples from the Colorado River...
Evaluation and control of corrosion and encrustation in tube wells of the Indus Plains, West Pakistan
Frank Eldridge Clarke, Ivan Barnes
1969, Water Supply Paper 1608-L
Seepage from rivers and irrigation canals has contributed to waterlogging and soil salinization problems in much of the Indus Plains of West Pakistan. These problems are being overcome in part by tube-well dewatering and deep leaching of salinized soils. The ground waters described here are anaerobic and some are supersaturated...
Water resources of Randolph and Lawrence Counties, Arkansas
A. G. Lamonds, Marion S. Hines, Raymond O. Plebuch
1969, Water Supply Paper 1879-B
Water is used at an average rate of almost 27 million gallons per day in Randolph and Lawrence Counties, and quantities sufficient for any foreseeable use are available. Supplies for the large uses--municipal, industrial, and irrigation--can best be obtained from wells in .he Coastal Plain part of the counties and...
Hydrogeology of the Scioto River Valley near Piketon, south-central Ohio
Stanley Eugene Norris, Richard E. Fidler
1969, Water Supply Paper 1872
A systematic study was made of one of Ohio's principal aquifers, a sand and gravel outwash in the Scioto River Valley, to determine the feasibility of developing a ground-water supply of 20 million gallons per day at a site near Piketon. The first part of the study was spent in...
Solubility of aluminum in the presence of hydroxide, fluoride, and sulfate
Charles Elmer Roberson, John David Hem
1969, Water Supply Paper 1827-C
The total concentration of aqueous dissolved species of aluminum that will be present in equilibrium with microcrystalline gibbsite at various levels of complexing ligand concentration are shown graphically. The graphs can be used to estimate aluminum solubility, at 25?C and 1 atmosphere total pressure, when the pH of the solution,...
Ground-water resources of the Wind River Indian Reservation, Wyoming
Laurence J. McGreevy, Warren Gayler Hodson, Samuel J. Rucker IV
1969, Water Supply Paper 1576-I
The area of this investigation is in the western part of the Wind River Basin and includes parts of the Absaroka, Washakie, Wind River, and Owl Creek Mountains. The purposes of the study were to determine the general hydrologic properties of the rocks in the area and the occurrence and...
Stage-discharge characteristics of a Weir in a sand-channel stream
Don D. Gonzalez, C.H. Scott, James K. Culbertson
1969, Water Supply Paper 1898-A
A unique relation between water-surface elevation and water discharge usually does not exist for sand-channel streams. The relation is affected by changes in bed roughness and changes in bed elevation because of scour and fill. An artificial control on a sand-channel stream must control both the resistance to flow and...
Water resources of Clark, Cleveland, and Dallas Counties, Arkansas
Raymond O. Plebuch, Marion S. Hines
1969, Water Supply Paper 1879-A
Clark, Cleveland, and Dallas counties constitute an area of 2,151 square miles in south-central Arkansas. The area is in two physiographic provinces--the Ouachita Mountains of the Ouachita province of the Interior Highlands, and the West Gulf Coastal Plain of the Coastal Plain province. The area is drained by the Ouachita,...
Water resources of Windward Oahu, Hawaii
K. J. Takasaki, George Tokusuke Hirashima, E.R. Lubke
1969, Water Supply Paper 1894
Windward Oahu lies in a large cavity--an erosional remnant of the Koolau volcanic dome at its greatest stage of growth. Outcrops include volcanic rocks associated with caldera collapse and the main fissure zone which is marked by a dike complex that extends along the main axis of the dome. The...
Water resources of the Sycamore Creek watershed, Maricopa County, Arizona
B. W. Thomsen, Herbert H. Schumann
1969, Water Supply Paper 1861
The Sycamore Creek watershed is representative of many small watersheds in the Southwest where much of the streamflow originates in the mountainous areas and disappears rather quickly into the alluvial deposits adjacent to the mountains. Five years of .streamflow records from the Sycamore Creek watershed show that an average annual...
Water in the Kahuku area, Oahu, Hawaii
K. J. Takasaki, Santos Valenciano
1969, Water Supply Paper 1874
The Kahuku area comprises the north end of the Koolau Range and its bordering coastal plain. This part of the range is less deeply eroded than oth3r parts, and except for long, narrow valleys and cliffs near the shore, it has retained the general shape of the original volcanic dome....
Estuarine studies in upper Grays Harbor, Washington
Joseph P. Beverage, Milton N. Swecker
1969, Water Supply Paper 1873-B
Improved management of the water resources of Grays Harbor, Wash., requires more data on the water quality of the harbor and a better understanding of the influences of industrial and domestic wastes on the local fisheries resources. To provide a more comprehensive understanding of these influences, the U.S. Geological Survey...
Factors initiating phytoplankton blooms and resulting effects on dissolved oxygen in Duwamish River estuary, Seattle, Washington
Eugene Brummer Welch
1969, Water Supply Paper 1873-A
Phytoplankton productivity, standing stock, and related environmental factors were studied during 1964-66 in the Duwamish River estuary, at Seattle, Wash., to ascertain the factors that affect phytoplankton growth in the estuary; a knowledge of these factors in turn permits the detection and evaluation of the influence that effluent nutrients have...
Floods of April 28, 1966 in the northern part of Dallas, Texas
Willard B. Mills, Elmer E. Schroeder
1969, Water Supply Paper 1870-B
The floods of April 28, 1966, in the northern part of Dallas, Tex., caused heavy damage to a relatively small area. Flood damage was estimated at $2,500,000; and of this amount, $1,330,000 damage was along Bachman Branch, which has a drainage area of 12.3 square miles. At least seven persons...
