Computation of records of streamflow at control structures
Dannie L. Collins
1977, Water-Resources Investigations Report 77-8
Traditional methods of computing streamflow records on large, low-gradient streams require a continuous record of water-surface slope over a natural channel reach. This slope must be of sufficient magnitude to be accuratly measured with available stage measuring devices. On highly regulated streams, this slope approaches zero during periods of low...
Water-level changes in wells along the west side of the Cedar Creek anticline, southeastern Montana
D.L. Coffin, T.E. Reed, S.D. Ayers
1977, Water-Resources Investigations Report 77-93
Water levels have been measured periodically in wells along the west side of the Cedar Creek anticline in southeastern Montana since 1962-64. The measurements show the response of the Fox Hills-Hell Creek aquifer of Late Cretaceous age to withdrawals for domestic, stock, and industrial uses. Water levels were as much...
Ground water in the Koehn Lake area, Kern County, California
J. H. Koehler
1977, Water-Resources Investigations Report 77-66
Hydrologic characteristics of the Koehn Lake area were investigated to determine the effects of external stresses on the system. Unconsolidated deposits are more than 900 feet thick in the central part of the basin. Cantil Valley fault, in the central part of the basin, acts as a barrier to the...
Water and related problems in coal-mine areas of Alabama
Alfred L. Knight, John G. Newton
1977, Water-Resources Investigations Report 76-130
Water-resource problems or potential problems in Alabama resulting from surface and subsurface coal mining include erosion and sedimentation, flooding, diversion of drainage, decline in water level, land subsidence, and the degradation of water quality. The degradation of water quality is the most serious and widespread coal-mine related problem in Alabama....
Water quality of selected streams in the coal area of southeastern Montana
J. R. Knapton, P. W. McKinley
1977, Water-Resources Investigations Report 77-80
This report summarizes and evaluates water-quality data collected at 35 stream sites the the coal region of southeastern Montana. Sarpy Creek, Armells Creek, and Rosebud Creek sometimes have dissolved-solids concentrations that cause water to be marginal for agricultural purposes. At times of rainfall and snowmelt, the runoff water mixes with...
Uranium mine waste water: potential source of ground water in northwestern New Mexico
W. L. Hiss
1977, Open-File Report 77-625
Substantial quantities of water are being pumped from the Morrison Formation of Late Jurassic age in uranium mines in the Grants mineral belt in northwestern New Mexico. The water often contains unacceptable amounts of dissolved uranium, radium, iron, and selenium and suspended solids, but with treatment it can be made...
Simulation studies of flow and sediment transport using a mathematical model, Atchafalaya River Basin, Louisiana
Marshall E. Jennings, Larry F. Land
1977, Water-Resources Investigations Report 77-14
Simulation studies were made of flow and sediment transport for the Atchafalaya River basin, Louisiana using a mathematical model calibrated and supplied by the Hydrologic Engineering Center and the New Orleans District, U.S. Army Corps of Engineers. The study results are based on three, 50-year computer simulations for the following...
Ground-water resources of the alluvial aquifers in northeastern Larimer County, Colorado
R. T. Hurr, P.A. Schneider
1977, Water-Resources Investigations Report 77-7
Ground water is a source of municipal, domestic, stock, and irrigation supply for most of northeastern Larimer County, Colo. A study of the alluvial aquifers in the northeastern part of the county was conducted to determine volume of water in storage, rate and location of ground-water withdrawals, and chemical quality...
Public water supplies of selected municipalities in Florida, 1975
H.G. Healy
1977, Water-Resources Investigations Report 77-53
In 1975, the 169 municipalities and 5 county water systems listed in this report supplied 1.037 million gallons of water each day, on the average to 77 percent of the population of the State of Florida. The quantity of water supplied represented 90 percent of the State's public water supply...
