Summary of water resources for the Campo, Cuyapaipe, La Posta, and Manzanita Indian Reservations and vicinity, San Diego County, California
W. R. Moyle, D.J. Downing
1978, Open-File Report 77-684
Since 1945, precipitation and runoff in California on the Campo, Cuyapaipe, La Posta, and Manzanita Indian Reservations and surrounding areas generally have been below normal, and ground-water levels are declining. Most of the water is of excellent quality. The analysis of water from one well on the Campo Reservation indicates...
A seismic refraction experiment performed in the Melones Reservoir region of the metamorphic belt, central California
James N. Murdock, John C. Roller
1978, Open-File Report 78-131
A seismic refraction experiment was conducted in the metamorphic belt of central California during May 1972. Seven charges were fired during the experiment. Three seismic refraction lines, 75 to 125 km long, were made in the belt. Also, data were gathered for regional travel-time calibrations. The experimental data are presented....

Fission-track dating of the Climax and Gold Meadows stocks, Nye County, Nevada
Charles W. Naeser, Florian Maldonado
1978, Open-File Report 78-419
Fission-track ages indicate an age of 101 m.y. for the Climax stock and a minimum age of 93.6 m.y. for the Gold Meadows stock, both at the Nevada Test Site, Nye County, Nevada. Younger fission-track ages for apatite concentrates suggest that the stocks have been within 4 km of the...

Study to determine discharge at 50-percent flow duration and ordinary high water for streams in Louisiana
Braxtel L. Neely Jr.
1978, Open-File Report 78-218
Techniques are presented for estimating the discharge at 50-percent duration and "ordinary high water" on ungaged streams in Louisiana that have drainage areas of less than 3,000 square miles. Discharge data from 91 gaging stations were used in developing the techniques. The discharge at 50-percent duration can be estimated if...
Sediment transport by irrigation return flows on the Yakima Indian Reservation, Washington 1975 and 1976 irrigation seasons
Leonard M. Nelson
1978, Open-File Report 78-947
As determined from data collected at 10 sites on the Yakima Indian Reservation during the 1975 and 1976 irrigation seasons (April-September), seasonal sediment discharges in irrigation return flows ranged from 11,000 tons from Marion Drain and Satus Drain 302, to 400 tons from Coulee Drain. There was little variation between...
Geologic setting of the lead and zinc deposits, Drenchwater Creek area, Howard Pass Quadrangle, Western Brooks Range, Alaska
Warren J. Nokleberg, Gary R. Winkler
1978, Open-File Report 78-70-C
Significant concentrations of galena, sphalerite, and minor barite are present in the Drenchwater Creek area, Howard Pass quadrangle, western Brooks Range, Alaska. Detailed geologic mapping indicates that galena, sphalerite and pyrite occur sporadically in a zone at least 1,830 m. long and 6-30 m. wide. The sulfides occur in tuff,...

1978, Open-File Report 78-470-A
Geochemical studies of the Rolla, Mo., 1° x 2° quadrangle were begun in 1977 as a part of a joint multidisciplinary study of the quadrangle by the U.S. Geological Survey and the Division of Geology and Land Survey, Missouri Department of Natural Resources. The study is to assess the mineral...

Placer gold deposits in the Mahd adh Dhahab district, Kingdom of Saudi Arabia
Abdulaziz Y. Bagdady, Jesse William Whitlow, Ralph Jackson Roberts
1978, Open-File Report 78-1074
Placer gold deposits in the Mahd adh Dhahab district were productive during ancient times, possibly during two periods, about 950 B.C. and 750— 1258 A.D. These deposits were mapped and systematically sampled in 1973 to determine their future potential. The sampling program was facilitated by use of a backhoe which...
Water-level records for the northern High Plains of Colorado, 1974-78
Ronald G. Borman
1978, Open-File Report 78-499
Water-level measurements were made in more than 600 wells in January 1978 in the northern High Plains of Colorado. Changes in water levels from January 1977 to January 1978 ranged from a rise of about 22 feet in Phillips County to a decline of about 14 feet in Yuma County....

Reconnaissance geology and geochronology of the Precambrian of the Granite Mountains, Wyoming
Zell E. Peterman, Robert A. Hildreth
1978, Professional Paper 1055
The Precambrian of the western part of the Granite Mountains, Wyoming, contains a metamorphic complex of gneisses, schists, and amphibolites that were derived through amphibolite-grade metamorphism from a sedimentary-volcanic sequence perhaps similar to that exposed in the southeastern Wind River Mountains. Whole-rock Rb-Sr dating places the time of metamorphism at...

Water-quality assessment of the Middle Fork Anderson River watershed, Crawford and Perry counties, Indiana
Mark A. Ayers
1978, Open-File Report 78-71
Surface-water quality in the watershed is generally good except for problem-causing concentrations of bacteria, dissolved oxygen, and phosphorus at some sites along the main stem during low flow and manganese at most sites year-round.Dissolved-solids concentration ranged from 76 to 248 milligrams per liter. Concentrations at sites upstream from reservoirs were...
Hydrologic reconnaissance of the Fish Springs Flat area, Tooele, Juab and Millard counties, Utah
E.L. Bolke, C. T. Sumsion
1978, Open-File Report 78-312
The Fish Springs Flat area includes about 590 square miles (1,530 square kilometers) in western Utah. Total annual precipitation on the area averages about 7 inches (180 millimeters) and totals about 232,000 acre-feet (286 cubic hectometers). Fish Springs Wash is the major drainage in the area; and, along with numerous...
Dissolved-oxygen depletion and other effects of storing water in Flaming Gorge Reservoir, Wyoming and Utah
E.L. Bolke
1978, Open-File Report 78-92
The circulation of water in Flaming Gorge Reservoir is caused chiefly by insolation, inflow-outflow relationships, and wind, which is significant due to the geographical location of the reservoir. During 1970-75, there was little annual variation in the thickness, dissolved oxygen, and specific conductance of the hypolimnion near Flaming Gorge Dam....
