Preliminary geologic map of the Deadman Spring NE quadrangle, Lincoln County, Nevada
W. C. Swadley, William R. Page, Robert B. Scott
1994, Open-File Report 94-283
Pesticides are used extensively in the largely agricultural Red River of the North (Red River) Basin, but, unlike many other agricultural basins, only small amounts are routinely detected in samples from streams in the basin. The pesticides detected comprise less than 2 percent of the amount applied and usually are...
Hydrology and geochemistry of a surface coal mine in northwestern Colorado
R.S. Williams Jr., G. M. Clark
1994, Water-Resources Investigations Report 92-4187
The hydrology and geochemistry of a reclaimed coal mine in northwestern Colorado were monitored during water years 1988 and 1989. Some data also were collected in water years 1987 and 1990. This report describes (1) the sources of hydrologic recharge to and discharge from reclaimed spoil, (2) the relative contributions...
Traveltime and reaeration characteristics for a reach of the Rio Grande, Albuquerque, New Mexico, October 1991
S. D. Waltemeyer
1994, Water-Resources Investigations Report 94-4071
Traveltime characteristics were determined using stream-velocity data and tracer-dye data for a reach of the Rio Grande. Traveltimes determined by the stream-velocity method were virtually the same as those determined by the tracer-dye and tracer-gas technique. The mean velocity of the stream was 1.12 miles per hour at a flow...
Potentiometric surface of the lower Potomac Aquifer in Virginia, 1993
E. C. Hammond, E. R. McFarland, M. J. Focazio
1994, Open-File Report 94-373
Ground-water level measurements from 17 wells in the lower Potomac aquifer in the Coastal Plain Physiographic Province of Virginia in 1993 were used to prepare a map of the potentiometric surface of the aquifer. The map shows the potentiometric surface of the lower Potomac aquifer indicating a regional trend toward...
Potentiometric surface of the middle Potomac Aquifer in Virginia, 1993
E. C. Hammond, E. R. McFarland, M. J. Focazio
1994, Open-File Report 94-372
Ground-water level measurements from 50 wells in the middle Potomac aquifer in the Coastal Plain Physiographic Province of Virginia in 1993 were used to prepare a map of the potentiometric surface of the aquifer. The map shows the potentiometric surface of the middle Potomac aquifer sharply declining eastward from nearly...
Hydrologic Instrumentation Facility of the U.S. Geological Survey, annual report for fiscal year 1993
V.J. Latkovich, Debra C. Tracey
1994, Open-File Report 94-353
The Hydrologic lnstrumentation Facility (HIF) of the U.S. Geological Survey (USGS) has nationwide responsibility for all aspects of hydrologic field instrumentation in support of Survey data-collection programs. Each year the HIF publishes a report to inform Water Resources Division (WRD) personnel of progress made by the HIF in fulfilling its...
Systematic paleontology of Quaternary ostracode assemblages from the Gulf of Alaska; Part 3, Family Cytheruridae
E. M. Brouwers
1994, Professional Paper 1544
Forty-six species of podocopid ostracodes, most belonging to the Family Cytheruridae, are reported from Quaternary continental-shelf sediments of the Gulf of Alaska. Descriptions and illustrations are provided for 27 new species, 11 previously described species, and 8 species retained in open nomenclature. This report is based on 198 bottom grab...
Estimated withdrawals and use of freshwater in New Hampshire, 1990
Laura Medalie, M.A. Horn
1994, Water-Resources Investigations Report 93-4096
Estimated freshwater withdrawals during 1990 in New Hampshire totaled about 422 million gallons per day from ground-water and surface-water sources. The largest withdrawals were for thermoelectric-power generation (60 percent), public supply (23 percent), and industrial use (9 percent). Most withdrawals, 358 million gallons per day, were made from surface- water...
