Cloudburst floods in Utah, 1939-69
Elmer Butler, Ray E. Marsell
1972, Report
During 1939-69, 836 cloudburst floods were reported in Utah. The largest number was in 1965, when 88 floods were reported; 63 floods were reported in 1968, and 56 were reported in 1961. The smallest number of floods reported was three in 1944. In 1942, 1948, and 1950, six floods were...
Reconnaissance geologic map of the Solomon D-6 quadrangle, Seward Peninsula, Alaska
C.L. Sainsbury, Travis Hudson, Rodney Ewing, Thomas Richards
1972, Open-File Report 72-325
The Solomon D-6 15- by 30-minute quadrangle lies 20 miles northeast of Nome, Alaska, and adjoins on the east the Nome D-l quadrangle mapped by Hummel (1962b) and on the west the Solomon D-5 quadrangle mapped by Smith (1910).Placer gold has been produced from Iron Creek and many of its...
Sediment transport and deposition, Walnut and Pacheco Creeks, Contra Costa County, California, August 1965-April 1970
George Porterfield
1972, Open-File Report 72-302
Average annual sediment discharge in Pacheco Creek basin, Contra Costa County, Calif., was larger during August 1965-April 1970 than the historical annual sediment discharge (1909-62) by a factor of about 1.3. This increas in sediment discharge is attributed primarily to an increased frequency of peak streamflows and to a larger...
Water-resources reconnaissance of Anaktuvuk Pass, Alaska
Charles E. Sloan
1972, Open-File Report 72-348
A hydrologic reconnaissance was made of Anaktuvuk pass in the central Brooks Range during the summer of 1971 to help develop a water supply for the village school. Winter icings and summer flow conditions in Contact Creek both indicate that ground water is present beneath the creek bed. A well-site...
Program design for San Francisco Bay Region environment and resources planning study
Water Resources Division, U.S. Geological Survey
1971, Open-File Report 1640
The "Program Design" for the San Francisco Bay Region Environment and Resources Planning Study represents a refinement, elaboration, and extension of the plans which formed the basis for the cooperative program between the Department of the Interior, Geological Survey, and the Department of Housing and Urban Development, Office of Research...
Water table in Long Island, New York, March 1971
Edward J. Koszalka, Ellis Koch
1971, Report
The geologic framework and the hydrologic situation in Long Island are periodically reviewed by the U.S. Geological Survey as new knowledge is obtained from current investigations. This work is done through cooperative programs with Nassau and Suffolk County agencies and the New York State Department of Environmental Conservation. A unique...
Effects of irrigation on streamflow in the Central Sand Plain of Wisconsin
E.P. Weeks, H.G. Stangland
1971, Open-File Report 70-362
Development of ground water for irrigation affects streamflow and water levels in the sand-plain area of central Wisconsin. Additional irrigation development may reduce opportunities for water-based recreation by degrading the streams as trout habitat and by lowering lake levels. This study was made to inventory present development of irrigation in...
Use of time-lapse photography equipment for hydrologic studies
J.R. Beck
1971, Report
This report describes equipment used for recording hydrologic events photographically on a controlled time scale. Equipment used included a 16-mm (millimeter) motion-picture camera, batteries, and associated intervalometer hardware.Variables that affected operation of the equipment, and which were used to turn the equipment on and off upon demand, were sunlight intensity,...
Preliminary results of induced polarization-resistivity surveys in the Northgate district, Colorado
Gordon Robert Francis Johnson
1971, Open-File Report 71-159
Induced polarization (I.P.) and resistivity surveys were made at selected locations in the Northgate district, Jackson County, Colorado. The objectives of the study were (1) to determine the feasibility of detecting and delineating pyrite-altered zones adjacent to fluorsparmineralized veins, and (2) to locate buried or obscured extensions of these fluorspar...
Relation of drainage problems to high ground-water levels, Coconut Grove area, Oahu, Hawaii
L.A. Swain, C.J. Huxel Jr.
1971, Open-File Report 72-365
Purpose and Scope In 1969, hydrologic data-collection sites were established in and around the Coconut Grove area for the purpose of measuring directly the relationship between rainfall, runoff, ground-water levels, the level of water in Kawainui Swamp and the canals, and tidal fluctuations. The primary objective was to identify the causes...
Resistivity sections, upper Arkansas River basin, Colorado
Adel A. R. Zohdy, Lloyd A. Hershey, Philip A. Emery, William D. Stanley
1971, Open-File Report 71-337
A reconnaissance investigation of ground-water resources in the upper Arkansas River basin from Pueblo to Leadville is being made by the U.S. Geological Survey in cooperation with the Southeastern Colorado Water Conservancy District, and the Colorado Division of Water Resources, Colorado State Engineer. As part of the investigation, surface geophysical...
Ground-water reconnaissance of selected sites in Rocky Mountain National Park and Shadow Mountain National Recreation area, Colorado
F.A. Welder
1971, Open-File Report 71-320
An evaluation of the ground-water supply potential at 30 sites within the Rocky Mountain National Park and Shadow Mountain National Recreation Area was made by the U.S. Geological Survey in 1967 and 1968. The work consisted of a geohydrologic reconnaissance, well inventory, and test drilling. The study sites are underlain...
Selected fluvial monazite deposits in the southeastern United States
William C. Overstreet, A. M. White, P. K. Theobald, D. W. Caldwell
1971, Open-File Report 71-222
Farther southwest in Georgia, around Griffin and Zebullon, along streams tributary to the Flint River in the monazite belt the flood plains are generally small and discontinuous, and only about 1 percent of the sediment is gravel. The area between Griffin, Zebullon, and the Flint River is underlain by biotite...
Geology of the Stroudsburg quadrangle and Adjacent areas, Pennsylvania--New Jersey
Jack Burton Epstein
1971, Open-File Report 71-95
The Stroudsburg area is within the Valley and Ridge and Great Valley physiographic provinces, Northampton and Monroe Counties, Pennsylvania, and Warren County, New Jersey. The northeast-trending subparallel valleys and ridges resulted from erosion of folded heterogeneous sedimentary rocks. These are Middle Ordovician to Middle Devonian in age and are more...
