Ground-water hydrology of the Sagebrush Flat area as related to the discharge of Rattlesnake Springs, Grant and Douglas counties, Washington
K.L. Walters
1980, Open-File Report 79-1530
In 1978, the U.S. Geological Survey, in cooperation with the State of Washington Department of Ecology, investigated the hydrology of the Sagebrush Flat area as it relates to Rattlesnake Springs. Rattlesnake Springs and all known wells on Sagebrush Flat obtain water from basalt aquifers. The wells tap aquifers at or...
Weather forecast needs from the viewpoint of hydrology
Donald M. Thomas, Thomas J. Buchanan
1980, Open-File Report 80-754
Hydrologists now depend on directly observed data in their forecasting and only infrequently use meteorological forecasts. Case studies show how reliable meteorological forecasts could be beneficial in flood and drought situations. Hydrologists need meteorological forecasts that recognize spatial variability, that are unbiased, and that have a specified degree of uncertainty....
Seismicity map of the State of Wisconsin
C. W. Stover, B.G. Reagor, S. T. Algermissen
1980, Miscellaneous Field Studies Map 1229
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...
Water resources data for Florida, water year 1979; Volume 3A. Southwest Florida quality of surface water
Water Resources Division, U.S. Geological Survey
1980, Water Data Report FL-79-3A
Water resources data for the 1979 water year for southwest Florida consist of records of stage, discharge, and water quality of streams; elevation and water quality of lakes and reservoirs; water-levels and water quality of wells; and discharge and water quality of springs. Additional water data were collected at various...
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)...
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...
Water resources data for West Virginia, water year 1979. Appendix - coal areas
Water Resources Division, U.S. Geological Survey
1980, Water Data Report WV-79-A
Water resources data for the 1979 water year for coal regions of West Virginia consist of records of discharge and water quality of streams, wells, mines, and abandoned mine shafts; and water levels in wells and abandoned mine shafts. Section 1 consists of data obtained for the statewide Coal Hydrology...
Ground-water data for the Riley and Andrews Resource Areas, southeastern Oregon
Paul J. Townley, Constance M. Soja, W.C. Sidle
1980, Open-File Report 80-419
Appraisals of the resources of selected management areas in eastern Oregon are being made by the U.S. Bureau of Land Mangement. To provide needed hydrologic information, the Bureau of Land Management requested the U.S. Geological Survey to inventory ground-water data for the Riley and Andrews Resource Areas. The inventory included...

Water resources data for West Virginia, water year 1979
Water Resources Division, U.S. Geological Survey
1980, Water Data Report WV-79-1
Water resources data for the 1979 water year for West Virginia consist of records of stage, discharge, and water quality of streams and springs; stage and contents of lakes and reservoirs; and water levels in wells. This report contains discharge records for 117 gaging stations; stage only records for 8...
Ground-water levels in selected well fields and in west-central Florida, September 1980
D. K. Yobbi, L. R. Mills, W. M. Woodham
1980, Open-File Report 81-77
The water table in the surficial aquifer and the potentiometric surface of the Floridan aquifer in a 1,200-square-mile area in west-central Florida are mapped semiannually by the U.S. Geological Survey. Maps are based on water levels measured in wells each May to coincide with seasonal low levels and each September...
