Synopsis of ground-water and surface-water resources of North Dakota
T. C. Winter, R.D. Benson, R. A. Engberg, G.J. Wiche, D. G. Emerson, O.A. Crosby, J.E. Miller
1984, Open-File Report 84-732
This report describes the surface- and ground-water resources of North Dakota and the limitations of our understanding of these resources. Ground water and surface water are actually one resource, because they are often hydraulically interconnected. They are discussed separately for convenience. In general, the surface-water resources of the mainstem of...
Stratigraphy and structure of the western Kentucky fluorspar district
R. D. Trace, D.H. Amos
1984, Professional Paper 1151-D
The western Kentucky fluorspar district is part of the larger Illinois-Kentucky fluorspar district, the largest producer of fluorspar in the United States. This report is based largely on data gathered from 1960 to 1974 during the U.S. Geological Survey-Kentucky Geological Survey cooperative geologic mapping program of Kentucky. It deals chiefly...
Glastonbury Gneiss and mantling rocks (a modified Oliverian dome) in south-central Massachusetts and north-central Connecticut: Geochemistry, petrogenesis, and isotopic age
G. W. Leo, R. E. Zartman, D. G. Brookins
1984, Professional Paper 1295
The Glastonbury dome is a long, narrow structure trending approximately 70 km north-northeast through Connecticut and Massachusetts along the west side of the Bronson Hill anticlinorium. Structurally and stratigraphically the dome is analogous to the Oliverian domes of New Hampshire. It is cored by Glastonbury Gneiss and is mantled by...
Water-quality and chemical loads of the Susquehanna River at Harrisburg, Pennsylvania, April 1980 to March 1981
David K. Fishel
1984, Water-Resources Investigations Report 83-4164
Water samples were analyzed for 42 chemical constituents to determine the water quality of the Susquehanna River at Harrisburg, Pennsylvania from April 1, 1980, to March 31, 1981. The investigation was part of the U.S. Environmental Protection Agency's (EPA) Chesapeake Bay Program's Fall Line Monitoring Project to provide information on...
Bathymetric map of Lydonia Canyon, U.S. Atlantic Outer Continental Shelf
Bradford Butman, John A. Moody
1984, Miscellaneous Field Studies Map 1710
Lydonia Canyon is one of several large submarine canyons that indent the eastern U.S. Continental Shelf along the southern flank of Georges Bank (Index map).  This bathymetric map of the upper part of Lydonia Canyon (water depths shallower than about 2,00 m) was prepared as part of a study of...
Application of a parameter-estimation technique to modeling the regional aquifer underlying the eastern Snake River Plain, Idaho
S. P. Garabedian
1984, Open-File Report 84-461
A nonlinear, least-squares regression technique for the estimation of ground-water flow model parameters was applied to the regional aquifer underlying the eastern Snake River Plain, Idaho. The computer program simulates two-dimensional, steady-state ground-water flow. Hydrologic data for the 1980 water year were used to calculate recharge rates, boundary fluxes, and...
Summary geochemical maps, Hoover Wilderness and adjacent study area, Mono and Tuolumne counties, California
M.A. Chaffee, R. H. Hill, S. J. Sutley
1984, Miscellaneous Field Studies Map 1101-B
The Hoover Wilderness and the adjacent Hoover Extension (East), Hoover Extension (West), and Cherry Creek A Roadless Areas (the adjacent study area) encompass approximately 153,900 acres (241 mi2; 623 km2) in the Inyo, Stanislaus, and Toiyabe Naitonal Forests, Mono and Tuolumne Counties, Calif. These two areas lie along and mostly...
White clays of Pennsylvania
John W. Hosterman
1984, Bulletin 1558-D
The white clays of Pennsylvania are composed chiefly of kaolinite and various amounts of illite. Most of the white clays are silty and a few are sandy. Quartz or chert is the only nonclay mineral in the whitest material; goethite is also present in the colored samples high in iron....
Sediment yields in eastern Montana; summary of data and proposed techniques for estimating sediment yields from small, ungaged watersheds
J. H. Lambing
1984, Water-Resources Investigations Report 84-4200
Sediment-yield data for 121 sites in eastern Montana have been compiled from results of studies conducted by various Federal, State, and private agencies. Methods used to determine mean annual sediment yields included reservoir sedimentation surveys, suspended-sediment sampling in streams, and estimates of gross erosion and indirect estimation based on physical...
Hydrology of Yucca Mountain and vicinity, Nevada-California — Investigative results through mid-1983
R. K. Waddell, J. H. Robison, R. K. Blankennagel
1984, Water-Resources Investigations Report 84-4267
Yucca Mountain, Nevada, is one of several sites under consideration for construction of the first repository for high-level nuclear waste. The climate is arid; few perennial streams are present in the region. Flash floods occasionally occur. The site is underlain by at least 1,800 meters of volcanic tuffs of Tertiary...
Compilation of selected hydrologic data from the MX missile-siting investigation, east-central Nevada and western Utah
Robin L. Bunch, James R. Harrill
1984, Open-File Report 84-702
Construction, water-level, and water-quality data for wells and site-description, discharge, and water-quality data for springs and streams in 37 hydrographic areas in Nevada and Utah are presented in this report. These data are grouped in tables, by area. Additional tables contain a summary of data and aquifer-test results for wells...
Habitat Suitability Index Models and Instream Flow Suitability Curves: White sucker
Kathleen A. Twomey, Kathryn L. Williamson, Patrick C. Nelson
1984, FWS/OBS 82/10.64
The white sucker (Catostomus commersoni) is a highly adaptable, freshwater fish species found in lacustrine and riverine environments from the Mackenzie River, Hudson Bay drainage, and the Labrador Peninsula; south along the Atlantic Coast to western Georgia; along the northern extremes of the Gulf States to northern Oklahoma; north through...
Index of surface-water stations in Texas, January 1984
E.R. Carrillo, H.D. Buckner
1984, Open-File Report 84-147
The U.S. Geological Survey's investigations of the water resources of Texas are conducted in cooperation with the Texas Department of Water Resources, river authorities, cities, counties, U.S. Army Corps of Engineers, U.S. Bureau of Reclamation, International Boundary and Water Commission, and others. Investigations are under the general direction of C. W....
Impact of development on availability and quality of ground water in eastern Nassau County, Florida, and southeastern Camden County, Georgia
D.P. Brown
1984, Water-Resources Investigations Report 83-4190
The primary sources of water in the area are from the surficial and Floridan aquifers. The surficial aquifer, consisting of thin permeable zones of sand, shell, and limestone, provides limited water supplies (10-50 gallons per minute). Its estimated transmissivity ranges from less than 100 to 10,000 feet squared per day....
