Trap-efficiency study, Highland Creek flood retarding reservoir near Kelseyville, California, water years 1966-77
L.F. Trujillo
1980, Open-File Report 80-735
This investigation is part of a nationwide study of trap efficiency of detention reservoirs. In this report, trap efficiency was computed from reservoir inflow and outflow sediment data and from reservoir survey and outflow data. Highland Creek Reservoir is a flood retarding reservoir located in Lake County, near Kelseyville, California....
Planning report for the southwest alluvial basins (east) regional aquifer-system analysis, parts of Colorado, New Mexico, and Texas
D. W. Wilkins, W. B. Scott, C. A. Kaehler
1980, Open-File Report 80-564
The study of the Southwest alluvial basins (east) will involve an analysis of the regional aquifer system in parts of Colorado, New Mexico, and Texas. This area has been divided into 22 basins. The study of the alluvial aquifer-system will be made in the following stages: (1) project planning, (2)...
Hydrologic data for North Creek, Trinity River basin, Texas, 1978
C.C. Kidwell
1980, Open-File Report 80-573
The U.S. Soil Conservation Service is actively engaged in the installation of flood- and soil-erosion reducing structures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The U.S. Soil Conservation Service has found...
Technique for estimating magnitude and frequency of floods in West Virginia
Gerald S. Runner
1980, Open-File Report 80-1218
A technique is presented to provide a method of estimating the magnitude of peak discharges of T-year frequencies for unregulated, virtually natural streams in West Virginia. Multiple regression techniques were used to develop the relation between peak discharges and drainage area. Data collected at 170 stream gaging sites were used...
Investigation of acidity and other water-quality characteristics of Upper Oyster Creek, Ocean County, New Jersey
Thomas V. Fusillo, J.C. Schornick Jr., H.E. Koester, D.A. Harriman
1980, Water-Resources Investigations Report 80-10
Water-quality data collected in the upper Oyster Creek drainage basin, Ocean County, N.J., indicate that the stream has excellent water quality except for a persistently low pH. The mean concentrations of the major inorganic ions were all less than 6.0 milligrams per liter. Mean concentrations of total nitrogen and total...
Nitrogen in ground water and surface water from sewered and unsewered areas, Nassau County, Long Island, New York
Stephen E. Ragone, B. G. Katz, G.E. Kimmel, J.B. Lindner
1980, Water-Resources Investigations Report 80-21
Data on nitrogen in groundwater and surface waters in the sewered and unsewered parts of Nassau County were analyzed to evaluate the principal sources of nitrogen and to determine what factors significantly affect its concentration in the upper glacial aquifer and the underlying Magothy aquifer. Nitrate data for water samples...
Columbia Glacier, Alaska: Recent ice loss and its relationship to seasonal terminal embayments, thinning, and glacial flow
W. G. Sikonia, Austin Post
1980, Hydrologic Atlas 619
In 1974 the U.S. Geological Survey began an intensive investigation of the stability of Columbia Glacier, a calving tidewater glacier terminating in Columbia Bay, near Valdez, Alaska. Aerial photographs taken in 1957 and a sequence of photographs taken at about 2-month intervals since 1976, when analyzed photogrammetrically, provided detailed data...
Seismicity map of the State of Michigan
C. W. Stover, B.G. Reagor, S. T. Algermissen
1980, Miscellaneous Field Studies Map 1228
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States in the United States (Algermissen, 1969) which have been recompiled and updated through 1977.  These data have been reexamined...
Maps showing kinds and sources of environmental geologic and geophysical data collected by the U.S. Geological Survey in the Baltimore Canyon trough area
James M. Robb, John R. Kirby
1980, Miscellaneous Field Studies Map 1210
Exploration for petroleum on the Continental Shelf and Slope off the eastern United States has generated great interest in the quantity and quality of data available to evaluate the nature and magnitude of possible geological enveironmental hazards.  This set of maps presents a compilation of publicly available geological and geophysical...
Seismicity map of the State of West Virginia
B.G. Reagor, C. W. Stover, S. T. Algermissen
1980, Miscellaneous Field Studies Map 1226
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States in the United States (Algermissen, 1969) which have been recompiled and updated through 1977.  These data have been reexamined...
Seismicity map of the State of Virginia
B.G. Reagor, C. W. Stover, S. T. Algermissen
1980, Miscellaneous Field Studies Map 1257
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States (Algermissen, 1969) which have been recompiled and updated through 1977. These data have been reexamined which resulted in some...
