Configuration and hydrology of the Pre-Cretaceous rocks underlying the southeastern Coastal Plain aquifer system
Robert L. Wait, Marvin E. Davis
1986, Water-Resources Investigations Report 86-4010
An investigation was conduced to define the configuration and hydrology of the rock surface upon which the sand aquifers and confining beds of the Southeastern Coastal Plain aquifer system were deposited. The base of the Southeastern Coastal Plain aquifer system consists of crystalline rocks, saprolite, Paleozoic rocks, Triassic sedimentary rocks...
Recharge zone of the Edwards aquifer hydrologically associated with Barton springs in the Austin area, Texas
Diana L. Slagle, Ann F. Ardis, Raymond M. Slade Jr.
1986, Water-Resources Investigations Report 86-4062
The Edwards aquifer extends in a narrow belt from Bell County in the northeast to Kinney County in the southwest (index map) and provides water for at least nine counties in south-central Texas. Hydrologic boundaries divide the Edwards aquifer in the Austin area for which Barton Springs is the major...
Water level and saturated thickness maps of the alluvial aquifer in eastern Arkansas, 1984
Maria Plafcan, Joe Edds
1986, Water-Resources Investigations Report 86-4014
The Mississippi River Valley alluvial aquifer, is a major source of water for most of eastern Arkansas. Agriculture is largely dependent on the aquifer as approximately 3.3 billion gallon per day are withdrawn for that purpose. Much smaller withdrawals also occur for industrial, public supply, and domestic use. The purpose...
Generalized potentiometric surface of the Catahoula aquifer in central Louisiana, 1980
Angel Martin Jr., Charles D. Whiteman Jr.
1986, Water-Resources Investigations Report 86-4059
Generalized contours of the altitude of water levels in wells completed in the Catahoula aquifer in central Louisiana, are illustrated by this map. Most water level measurements used in compiling the map were made in 1980; however, in parts of the State where water levels from 1980 were unavailable and...
Altitude of the freshwater-saltwater interface in a regionally extensive coastal plain aquifer of Mississippi, Alabama, and Georgia
Donald J. Strickland, Gary L. Mahon
1986, Water-Resources Investigations Report 86-4058
Geophysical well logs from over 150 oil test and water wells in Mississippi, Alabama, and Georgia were examined and calculations of the dissolved solids concentration in ground water were made using the spontaneous potential deflection as a measure of ionic activity. The values derived from these calculations were used to...
Hydrogeologic and water-quality characteristics of crystalline-rock aquifers of Archean and Proterozoic age, Minnesota
H. W. Anderson Jr.
1986, Water-Resources Investigations Report 86-4033
Five aquifers in crystalline rocks of Archean and Proterozoic age in Minnesota include in descending order the North Shore Volcanic, Sioux Quartzite, Proterozoic metasedimentary, Biwabik Iron formation and undifferentiated Precambrian aquifers. The North Shore Volcanic aquifer generally yields < 15 gal/min to wells from interflow sediments and fractures in the...
Ground-water availability in the Black River Basin, New York
Roger Milton Waller
1986, Water-Resources Investigations Report 86-4040
There are three maps in this set, which were prepared in 1966-68 as part of a study on the water resources of the Black River basin in cooperation with the New York State Department of Environmental Conservation. The data presented on the maps show well locations, well yield from bedrock...
Surficial geology and ground-water availability in the Allegheny River basin and part of the Lake Erie basin, New York
Michael H. Frimpter
1986, Water-Resources Investigations Report 86-4041
New York State 's need to develop a groundwater management program for protection of its aquifers led in 1985 to a cooperative program between the U.S. Geological Survey and the New York State Department of Environmental Conservation (through regional planning agencies) to publish data from previous studies. The two maps...
Hydrogeologic and water-quality characteristics of the Cretaceous aquifer, southwestern Minnesota
D. G. Woodward, H. W. Anderson Jr.
1986, Water-Resources Investigations Report 84-4153
The Cretaceous aquifer in southwest Minnesota consists of discontinuous, basal sandstone beds in the Dakota Formation and the overlying Codell Sandstone Member of the Carlile Shale of the Colorado Group. These sandstone beds are not laterally or vertically persistent throughout the area and generally are separated shale beds in the...
Evaluation of the U.S. Geological Survey's gaging-station network in Illinois
D. M. Mades, K. A. Oberg
1986, Water-Resources Investigations Report 86-4072
Data collected at 97 of the 176 gaging stations operated in Illinois during 1983 were used to describe rainfall-runoff processes, to monitor and forecast floods, and to monitor and regulate lake levels, discharge from reservoirs, or discharge of navigable streams. Stream-gaging stations on the Illinois River at Havana, East Branch...
Summary geochemical maps for samples of rock, stream sediment, and nonmagnetic heavy-mineral concentrate, Sweetwater Roadless Area, Mono County, California and Lyon and Douglas Counties, Nevada
Maurice A. Chaffee
1986, Miscellaneous Field Studies Map 1535-C
The Sweetwater Roadless Area lies between Yerington, Nevada, and Bridgeport, California, along the California-Nevada boundary. The area encompasses approximately 72,240 acres in Toiyabe National Forest in Mono County, California, and Lyon and Douglas Counties, Nevada. This roadless area, which lies just east of the Sierra Nevada range, exhibits rugged topography. Elevations...
Shallow ground-water conditions, Tom Green County, Texas
J.N. Lee
1986, Water-Resources Investigations Report 86-4177
Most of the water needs of Tom Green County, Texas, are supplied by ground water; however, the city of San Angelo is supplied by surface water. Groundwater withdrawals during 1980 (latest year for which data are available) in Tom Green County totaled about 15,300 acre-feet, all derived from shallow aquifers....
Hydrologic characteristics of soils in parts of Arkansas, Colorado, Kansas, Missouri, Nebraska, New Mexico, Oklahoma, South Dakota, and Texas
Jack T. Dugan
1986, Hydrologic Atlas 678
Certain physical characteristics of soils, including permeability, available water capacity, thickness, and topographic position, have a definite effect on the hydrology of an area. They control the rate at which precipitation infiltrates or is transmitted through the soil, and thus they have a significant role in determining the rates both...
