Data uses and funding of the streamflow-gaging program in North Dakota
Gerald L. Ryan
1985, Open-File Report 85-349
This report documents the uses, funding, and availability of the streamflow data currently collected in North Dakota. Presently (1984), 94 streamflow-gag ing stations are operated in North Dakota on a budget of $663,000. Station type, data uses, and funding sources are identified for each of the 94 stations. Data from...
Estimated public-water supply and industrial-commercial ground-water withdrawals and returns in Nassau County, Long Island, New York, 1973-79
D. S. Snavely, J. F. Williams
1985, Water-Resources Investigations Report 84-4246
Nassau County, New York depends upon ground water for its freshwater supply. The primary water uses are for public-water supply and industrial-commercial purposes, which together accounted for 202 Mgal/d (million gallons per day) in 1975. Public-water suppliers withdrew 85 percent of their water from the Magothy Formation. About 133 Mgal/d...
Effects of wastewater effluent on the South Platte River from Littleton to Denver
N.E. Spahr, S. R. Blakely
1985, Water-Resources Investigations Report 85-4124
The U.S. Geological Survey 's one-dimensional steady-state water quality model was used to investigate the effects of the effluent from the Bi-City WWTP (Wastewater Treatment Plant) on the South Platte River. The Bi-City WWTP is operated by the Cities of Littleton and Englewood. The model was calibrated from a 14.5...
Estimation of evaporation from Ned Wilson Lake, Flat Tops Wilderness Area, Colorado
N.E. Spahr, J.T. Turk
1985, Water-Resources Investigations Report 85-4244
As part of an effort to define the hydrology and water quality of Ned Wilson Lake, evaporation rates were estimated for the summer periods of 1983 and 1984. Mass-transfer and energy-budget techniques and the Morton model were used to estimate evaporation using data collected at the lake and data collected...
Chemical and biological quality of selected lakes in Ohio, 1978 and 1979
C.G. Angelo, John D. Youger
1985, Open-File Report 84-249
Twenty-eight Ohio lakes were sampled by the U.S. Geological Survey and the Ohio Environmental Protection Agency for water-quality characteristics during the spring and summer of 1978 and 1979. This report is the third in a series covering a lake-sampling program that began in 1975. Data include water-column profiles of temperature,...
A two-constituent solute-transport model for ground water having variable density
W. E. Sanford, Leonard F. Konikow
1985, Water-Resources Investigations Report 85-4279
A numerical model has been developed to simulate solute transport and dispersion of either one or two constituents in groundwater where there is two-dimensional, density-dependent flow. The model is a modified version of the one documented by Konikow and Bredehoeft (1978), which uses finite-difference methods and the method of characteristics...
Effects of surface mining on streamflow, suspended-sediment, and water quality in the Stony Fork drainage basin, Fayette County, Pennsylvania
D.E. Stump, T.M. Mastrilli
1985, Water-Resources Investigations Report 84-4362
A study of the Stony Fork basin in southern Fayette County, Pennsylvania, from 1977 through 1980 determined the impacts of surface coal mining on surface-water quality. Stony Fork was sampled at six sites, during which time the area of surface mines increased from 0.5 to 5.5 percent of the study...
Mathematical model of the Tesuque aquifer system near Pojoaque, New Mexico
Glenn A. Hearne
1985, Water Supply Paper 2205
A three-dimensional digital model of ground-water flow was constructed to represent the dipping anisotropic beds of the Tesuque aquifer system underlying the Pojoaque River basin and vicinity, New Mexico. Simulations of steady-state conditions and historical ground-water withdrawals were consistent with observed data. The model was used to simulate the response...
Classification of stream basins in southeastern Ohio according to extent of surface coal mining
C.J. Childress
1985, Water-Resources Investigations Report 84-4212
Water-quality data were collected from streams grenadine 35 basins in the southeaster-Ohio coal region to evaluate and categorize the effect of surface coal mining on stream quality. The study area is underlain by rocks of Pennsylvanian age, the most important coal-producing formations of which are the Allegheny and Monogahela Formations. The...
Small-area snow surveys on the northern plains of North Dakota
Douglas G. Emerson, T.R. Carroll, Harold Steppuhn
1985, Water-Resources Investigations Report 85-4026
Snow-cover data are needed for many facets of hydrology. The variation in snow cover over small areas is the focus of this study. The feasibility of using aerial surveys to obtain information on the snow water equivalent of the snow cover in order to minimize the necessity of labor intensive...
Simulated effects of projected pumping on the availability of freshwater in the Evangeline Aquifer in an area southwest of Corpus Christi, Texas
George E. Groschen
1985, Water-Resources Investigations Report 85-4182
This study is an investigation of the continued availability of freshwater in the Evangeline aquifer along the Texas Gulf Coast and the potential for degradation of the water quality by salinewater intrusion. Recharge to the aquifer occurs by the infiltration of precipitation in the outcrop area and by cross-formational flow...
Streamflow and sediment data collected at seven stream-gaging stations in the James River basin downstream from Forestburg, South Dakota, from October 1, 1982 to September 30, 1983
J.R. Little
1985, Open-File Report 85-156
A compilation of streamflow and suspended-sediment data collected from October 1, 1982, to September 30, 1983, at seven gaging stations in the James River basin downstream from Forestburg, South Dakota, is presented in tabular and graphic form. Three of the gaging stations are on the main stem and four are...
