Water Resources Data for California, water year 1981: Vol. 1. Colorado River basin, Southern Great basin from Mexican Border to Mono Lake basin, and Pacific slope basins from Tijuana River to Santa Maria River
Water Resources Division, U.S. Geological Survey
1982, Water Data Report CA-81-1
Water-resources data for the 1981 water year for California consists of records of stage, discharge, and water quality of streams; stage and contents in lakes and reservoirs; and water levels and water quality in wells. Volume 1 contains discharge records for 169 gaging stations; stage and contents for 19 lakes...
Geochemical survey of the Ramseys Draft Addition, Augusta and Highland counties, Virginia
Frank G. Lesure
1982, Miscellaneous Field Studies Map 1369-B
The U.S. Geological Survey (USGS) made a reconnaissance geochemical survey of the Ramseys Draft Addition (fig.1) to test for indistinct or unexposed mineral deposits that might be recognized by their geochemical halos.  Thirty-three stream-sediment, two soil, and 22 rock samples were collected from the addition during the earlier study of...
Map projections used by the U.S. Geological Survey
John Parr Snyder
1982, Bulletin 1532
After decades of using only one map projection, the Polyconic, for its mapping program, the U.S. Geological Survey (USGS) now uses sixteen of the more comnon map projections for its published maps. For larger scale maps, including topographic quadrangles and the State Base Map Series, conformal projections such as the...
Thermal springs in the Salmon River basin, central Idaho
H.W. Young, R.E. Lewis
1982, Open-File Report 82-104
The Salmon River basin drains approximately 13,000 square miles in central Idaho underlain by the Idaho batholith. Geologic units in the basin include igneous, sedimentary, and metamorphic rocks and granitic rocks predominate. Water from thermal springs ranges in temperature from 20.5 degrees to 94.0 degrees Celsius. The waters are slightly...
Water resources data for Connecticut, water year 1981
Water Resources Division, U.S. Geological Survey
1982, Water Data Report CT-81-1
Water resources data for the 1981 water year for Connecticut consist of records of stage, discharge, and water quality of streams; contents and water quality of lakes and reservoirs; and water levels and water quality of ground-water wells. This volume contains records for water discharge at 55 gaging stations; storm...
Effects of Late Cretaceous and Cenozoic faulting on the geology and hydrology of the coastal plain near the Savannah River, Georgia and South Carolina
R.E. Faye, D.C. Prowell
1982, Open-File Report 82-156
Geologic and hydrologic investigations by the U.S. Geological Survey have defined stratigraphic and hydraulic anomalies suggestive of faulting within Coastal Plain sediments between the Ogeechee River in east-central Georgia and the Edisto River in west-central South Carolina. Examination of borehole cuttings, cores, and geophysical logs from test wells indicate that...
Electrical studies at the proposed Wahmonie and Calico Hills nuclear waste sites, Nevada Test Site, Nye County, Nevada
D.B. Hoover, Michael P. Chornack, K.H. Nervick, M. M. Broker
1982, Open-File Report 82-466
Two sites in the southwest quadrant of the Nevada Test Site (NTS) were investigated as potential repositories for high-level nuclear waste. These are designated the Wahmonie and Calico Hills sites. The emplacement medium at both sites was to be an inferred intrusive body at shallow depth; the inference of the...
CONTOUR; a modification of G.I. Evenden's general purpose contouring program
R. H. Godson, M. W. Webring
1982, Open-File Report 82-797
A contouring program written for the DEC-10 computer (Evenden, 1975) has been modified and enhanced to operate on a Honeywell Multics 68/80 computer. The program uses a device independent plotting system (Wahl, 1977) so that output can be directed to any of several plotting devices by simply specifying one input...
Water-quality characteristics of streams in forested and rural areas of North Carolina
Clyde E. Simmons, Ralph C. Heath
1982, Water Supply Paper 2185-B
Data collected in North Carolina during 1973-78 from a statewide network of 39 rural sampling sites were used to define unpolluted or baseline stream quality. The basins were 90 to 100 percent forested and, except for the unknown effects of air pollution, were relatively unaffected by man 's activities. Five...
U.S. Geological Survey research in radioactive waste disposal - Fiscal year 1979
Robert Schneider, E.H. Roseboom, J.B. Robertson, P. R. Stevens
1982, Circular 847
The report summarizes progress on geologic and hydrologic research related to the disposal of radioactive wastes. The research is described according to whether it is related most directly to: (1) high-level and transuranic wastes; (2) low-level wastes, or (3) uranium mill tailings. Included is research applicable to the identification and...
Statistical summaries of water-quality data for two coal areas of Jackson County, Colorado
Gerhard Kuhn
1982, Open-File Report 82-121
Statistical summaries of water-quality data are compiled for eight streams in two separate coal areas of Jackson County, Colo. The quality-of-water data were collected from October 1976 to September 1980. For inorganic constituents, the maximum, minimum, and mean concentrations, as well as other statistics are presented; for minor elements, only...
Estimating peak flow characteristics at ungaged sites by ridge regression
Gary D. Tasker
1982, Open-File Report 82-333
A regression simulation model, is combined with a multisite streamflow generator to simulate a regional regression of 50-year peak discharge against a set of basin characteristics. Monte Carlo experiments are used to compare the unbiased ordinary lease squares parameter estimator with Hoerl and Kennard's (1970a) ridge estimator in which the...
