Appraisal of ground water for irrigation in the Little Falls area, Morrison County, Minnesota
John O. Helgesen
1973, Water Supply Paper 2009-D
Anticipated irrigation on sandy soils has prompted evaluation of ground-water supply potential in the Little Falls area. Geologic conditions cause ground-water availability to vary widely in the area. The largest and most readily available groundwater source is the glacial outwash sand and gravel from which the soils were derived. Test augering...
Preparative free-flow electrophoresis as a method of fractionation of natural organic materials
J.A. Leenheer, Ronald L. Malcolm
1973, Water Supply Paper 1817-D
Preparative free-flow electrophoresis was found to be an efficient method of conducting large-scale fractionations of the natural organic polyelectrolytes occurring in many surface waters and soils. The method of free-flow electrophoresis obviates, the problem of adsorption upon a supporting medium and permits the use of high potential gradients and currents...
Ground water in the Eugene-Springfield area, southern Willamette Valley, Oregon
F. J. Frank
1973, Water Supply Paper 2018
The cities of Eugene and Springfield and their outlying suburban and rural districts constitute an area of rapid population growth where progressively greater volumes of ground water are being required for irrigation and industrial and public supplies. The area is also one of diverse geologic and hydrologic conditions. As used...
Cost analysis of ground-water supplies in the North Atlantic region, 1970
Dagfin John Cederstrom
1973, Water Supply Paper 2034
The cost of municipal and industrial ground water (or, more specifically, large supplies of ground water) at the wellhead in the North Atlantic Region in 1970 generally ranged from 1.5 to 5 cents per thousand gallons. Water from crystalline rocks and shale is relatively expensive. Water from sandstone is less...
Water resources and geology of Mount Rushmore National Memorial, South Dakota
J.E. Powell, James Jennings Norton, D. G. Adolphson
1973, Water Supply Paper 1865
Ground water suitable for public supply can be obtained from fractured metamorphic and igneous rooks at Mount Rushmore National Memorial, S. Dak. The memorial comprises three main drainage basins: Starling basin, Lafferty Gulch basin, and East Boundary basin. Ground water is most prevalent in Lafferty Gulch basin but Starling basin contributes...
A national study of the streamflow data-collection program
Manuel A. Benson, Rolland William Carter
1973, Water Supply Paper 2028
The streamflow data program of the U.S. Geological Survey was evaluated in a nationwide study during 1970. The principal elements of the study were (1) establishing the objectives and goals of the program, (2) analyzing all available data to determine which of the goals have already been met, (3) considering...
Effects of coal mining on the water resources of the Tradewater River Basin, Kentucky
Hayes F. Grubb, Paul D. Ryder
1973, Water Supply Paper 1940
The effects of coal-mine drainage on the water resources of the Tradewater River basin, in the Western Coal Field region of Kentucky, were evaluated (1) by synthesis and interpretation of 16 years of daily conductance data. 465 chemical analyses covering an 18-year period, 28 years of daily discharge data, and...
Chemical quality of surface water in the Flaming Gorge Reservoir area, Wyoming and Utah
R. J. Madison, Kidd M. Waddell
1973, Water Supply Paper 2009-C
Construction of Flaming Gorge Dam on the Green River by the U.S. Bureau of Reclamation started in 1959, and storage began in November 1962. A reconnaissance study was made during the period 1966-68 to determine the effects of the reservoir on the chemical quality of the effluent water and to...
Water resources of the Big Sioux River Valley near Sioux Falls, South Dakota
Donald G. Jorgensen, Earl A. Ackroyd
1973, Water Supply Paper 2024
The major sources of water in the Big Sioux River valley between Sioux Falls and Dell Rapids, S.Dak., are the Big Sioux River and the glacial outwash aquifer beneath the flood plain. The river and the aquifer are hydraulically connected. The Big Sioux River has an average annual discharge of 246...
Water resources of the New Jersey part of the Ramapo River basin
John Vecchioli, E.G. Miller
1973, Water Supply Paper 1974
The Ramapo River, a major stream in the Passaic River basin, drains an area of 161 square miles, 70 percent of which is in Orange and Rockland Counties, N.Y., and 30 percent is in Bergen and Passaic Counties, N.J. This report describes the hydrology of the New Jersey part of...
Use of finite-difference arrays of observation wells to estimate evapotranspiration from ground water in the Arkansas River Valley, Colorado
Edwin P. Weeks, M.L. Sorey
1973, Water Supply Paper 2029-C
A method to determine evapotranspiration from ground water was tested at four sites in the flood plain of the Arkansas River in Colorado. Approximate ground-water budgets were obtained by analyzing water-level data from observation wells installed in five-point arrays. The analyses were based on finite difference approximations of the differential...
Ground-water levels in the United States, 1967-71, north-central States
Water Resources Division, U.S. Geological Survey
1973, Water Supply Paper 2090
Publication of ground-water level data for the United States in watersupply papers was begun by the Geological Survey in 1935. From 1935 through 1939, a single water-supply paper for each year covering the entire Nation was issued (Water-Supply Papers 777, 817, 840, 845, and 886). Since then water-supply papers have...
