Map showing outcrops of granitic rocks, Basin and Range Province, Nevada
K. A. Sargent, Kurt Roggensack
1984, Water-Resources Investigations Report 83-4119-D
This map report is one of a series of geologic and hydrologic maps covering all or parts of States within the Basin and Range province of the western United States. The map reports contain information on subjects that characterize the geohydrology of the province, including the ground-water hydrology, ground-water quality,...
Low-Flow Characteristics of Kentucky Streams, 1984
John N. Sullavan
1984, Open-File Report 84-705
INTRODUCTION The U. S. Geologlcal Survey has been gathering low-flow data on streams throughout Kentucky for many years. This report presents low-flow characteristics at gaged and ungaged sites where the flow is not significantly regulated. Data on avai1able streamflow during low-flow periods are used for the design of plants that dispose...
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...
Maps showing ground-water units and withdrawal, Basin and Range Province, Texas
B. T. Brady, M. S. Bedinger, John Mikels
1984, Water-Resources Investigations Report 83-4121-A
This report on ground-water units and withdrawal in the Basin and Range province of Texas (see index map) was prepared as part of a program of the U.S. Geological Survey to identify prospective regions for further study relative to isolation of high-level nuclear waste (Bedinger, Sargent, and Reed, 1984), utilizing...
A statistical approach to evaluate the relation of coal mining, land reclamation, and surface-water quality in Ohio
Janet Hren, K. S. Wilson, D.R. Helsel
1984, Water-Resources Investigations Report 84-4117
Base-flow data from 779 sites in Ohio 's coal region were analyzed statistically to relate land use to selected water-quality characteristics. Sites were classified into five categories: unmined (100 percent unmined land), abandoned (50 percent or more abandoned surface mines), reclaimed (50 percent or more reclaimed surface mines), deep-mined (50...
Determination of reaeration coefficients for Ohio streams
Janet Hren
1984, Water-Resources Investigations Report 84-4139
The hydrocarbon-gas tracer technique was used to determine reaeration coefficients on 30 reaches of Ohio streams. The studies were done from September 1979 through August 1982 to determine the reaeration coefficients for the individual reaches and to develop general equation that could be used to estimate the coefficients. Multiple linear...
Water resources data, Michigan, water year 1983
J. B. Miller, J.L. Oberg, T. Sieger
1984, Water Data Report MI-83-1
Water resources data for the 1983 water year for Michigan consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water temperature of ground water. This report contains discharge records for 143 gaging stations; stage only...
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...
Mapping of forested wetland: Use of seasat radar images to complement conventional sources
John L. Place
1984, Open-File Report 84-312
Distinguishing forested wetland from dry forest using aerial photographs has been handicapped because photographs often do not reveal the presence of water below the tree canopies. Images obtained during the summer months of 1978 by the Seasat satellite's L-band (23-cm) radar reveal forested wetland as patterns of high radar reflection in the Atlantic coastal...
Recharge and discharge areas of the Floridan Aquifer in the St. Johns River Water Management District and vicinity, Florida
G. G. Phelps
1984, Water-Resources Investigations Report 82-4058
The Floridan aquifer is the principal source of most of the freshwater used in the St. Johns River Water Management District. An important step in managing water resources is the delineation of recharge and discharge areas. Geohydrologic factors to be considered when delineating recharge and discharge areas include: altitude and...
Brief statement on the hydrology of the Sampit River area near Georgetown, South Carolina
J.M. Cahill
1984, Open-File Report 84-243
The Carolina Refining and Distributing Company is planning to locate an oil-refining plant near Georgetown, South Carolina. To aid in the preparation of an environmental impact statement, a description of the stratigraphy, ground-water resources, and an assessment of possible seismic activity that may occur in the Winyah Bay vicinity has...
Water-resources investigations in North Dakota; fiscal year 1984
L.A. Hall, R.K. Kuzniar
1984, Open-File Report 84-429
The U.S. Geological Survey, through its Water Resources Division, investigates the occurrence, quantity, quality, distribution, and movement of the surface and underground water that composes the Nation's water resources. This publication contains a brief description of the ongoing investigations of the North Dakota District.Much of the Geological Survey program is...
Occurrence of beds of low hydraulic conductivity in surficial deposits of Florida
Henry G. Healy, James D. Hunn
1984, Water-Resources Investigations Report 84-4210
The disposal of municipal and industrial wastes on or at shallow depths below land surface can result in contamination of ground water--the source of drinking water for more than 90 percent of Florida 's residents. This threat to public health has resulted in new State groundwater regulations. Knowledge of the...

S.D. Goodwin, B.I. Schultz, D.L. Parkhurst, N.S. Simon, Edward Callender
1984, Open-File Report 84-74
The chemical composition of bottom sediments and their associated pore waters from the tidal Potomac River and Estuary was studied from May 1978 through June 1980. Pore waters were routinely analyzed for pH, Eh, alkalinity, and concentrations of sulfide, sulfate, phosphate, carbon, ammonium, silica, iron, manganese, chloride, sodium, potassium, calcium,...
