Reconnaissance water-balance study of Lake Gregory, California
C.E. McConaughy
1982, Open-File Report 82-367
A study was made to determine the magnitude and distribution of the surface-water inflow and outflow (water balance) of the Lake Gregory basin in southern California. Data were collected from April 1979 through June 1981. Runoff during the study period varied greatly with the majority of inflow occurring between December...
Map showing the potentiometric surface of the Magothy Aquifer in southern Maryland, September 1982
Frederick K. Mack, Judith C. Wheeler, Stephen E. Curtin
1982, Water-Resources Investigations Report 83-4282
A map was prepared that shows the potentiometric surface of the Magothy aquifer in southern Maryland in September 1982. The map is based on measurements from a network of 83 observation wells. The highest levels of the potentiometric surface, 57 and 58 feet above sea level, were measured near the...
Preliminary evaluation of the potential for artificial ground-water recharge in eastern San Joaquin County, California
H. T. Mitten
1982, Open-File Report 82-123
In response to increasing demand on water supplies and declining water levels in San Joaquin County, the U. S. Geological Survey, in cooperation with the San Joaquin County Flood Control and Water Conservation District, is evaluating the potential for artificially recharging the aquifer system in eastern San Joaquin County, California....
Analysis of three tests of the unconfined aquifer in southern Nassau County, Long Island, New York
J.B. Lindner, T. E. Reilly
1982, Water-Resources Investigations Report 82-4021
Drawdown and recovery data from three 2-day aquifer tests (OF) the unconfined (water-table) aquifer in southern Nassau County, N.Y., during the fall of 1979, were analyzed. Several simple analytical solutions, a typecurve-matching procedure, and a Galerkin finite-element radial-flow model were used to determine hydraulic conductivity, ratio of horizontal to vertical...
Streamflows and channels of the Green River basin, Wyoming
H. W. Lowham
1982, Water-Resources Investigations Report 81-71
Width, depth, cross-sectional area, and velocity of streamflow were depicted for 51 gaged sites in or near the Green River basin of Wyoming by summarizing data obtained from current-meter discharge measurements. Using these at-a-station relations as a base, regional relations were then developed that characterize hydraulic features of streams throughout...
Methodology for hydrologic evaluation of a potential surface mine: Loblolly Branch basin, Tuscaloosa County, Alabama
Lynn M. Shown, D. G. Frickel, R.F. Miller, F.A. Branson
1982, Water-Resources Investigations Report 82-50
Methodology for evaluating premining hydrology and postmining effects of mining and reclamation on the hydrology of an area is presented for a potential mine-permit area of 1,680 acres in the Warrior Coal Field, northwestern Alabama.Information is included on climate, geology, soil-water relations, vegetation, surface water, ground water, and quality of...
A national water-use information program
William B. Mann, John E. Moore, Edith B. Chase
1982, Open-File Report 82-862
The U.S. Geological Survey has compiled estimates of water use every five years since 1950. These estimates have been derived from many sources, and have a wide range of accuracy. Therefore, they fall short of providing a national data base that is both current and reliable. In 1977, the Congress...
Chloride Concentration in Water from the Upper Permeable Zone of the Tertiary Limestone Aquifer System, Southeastern United States
Craig L. Sprinkle
1982, Water-Resources Investigations Report 81-1103
INTRODUCTION The tertiary limestone aquifer system of the southeastern United States is a sequence of carbonate rocks referred to as the Floridan aquifer in Florida and the principal artesian aquifer in Georgia, Alabama, and South Carolina. More than 3 billion gallons of water are pumped daily from the limestone aquifer; and...
