Water resources of Upper Separation Creek Basin, south-central Wyoming
L. R. Larson, Everett Alfred Zimmerman
1981, Water-Resources Investigations Report 80-85
Expected development of coal in the 85-square-mile upper Separation Creek basin of south-central Wyoming will greatly increase the demands on water resources. Flows in Separation Creek are seasonal and highly variable. Streamflow is primarily caused by snowmelt. Very light snowpack in the spring of 1977 resulted in annual runoff being...

A stochastic streamflow model of the Platte River at Overton, Odessa, and Grand Island, Nebraska
A.V. Vecchia Jr.
1981, Open-File Report 81-1188
A stochastic model is developed to simulate flows for three seasons (September through February, March and April, May through August) at Overton, Odessa, and Grand Island, Nebraska on the Platte River. The model preserves the first and second order moment properties of the historical flow series, including significant autocorrelations within...

Reconnaissance of water availability and quality in abandoned coal mines near Roslyn, Kittitas County, Washington
F. A. Packard
1981, Open-File Report 80-955
The recoverable volume of ground water in abandoned coal mines near Roslyn, Wash., is estimated to be 20,000 acre-feet. During times of drought, pumping this water into the Cle Elum and Yakima Rivers for use in irrigation downstream should present few major water-quality problems. Wells at seven locations should be...

January 1981 water levels, and data related to water-level changes, western and south-central Kansas
Marilyn E. Pabst
1981, Open-File Report 81-1001
This report provides hydrologic data related to water-level measurements in observation wells in western and south-central Kansas during January 1981. Annual water-level measurements are made by personnel from the Division of Water Resources, Kansas State Board of Agriculture, and from the U.S. Geological Survey . State-agency support for this cooperative...
Selected biological characteristics of streams in the southeastern Uinta Basin, Utah and Colorado
Ronald W. Naten, Richard H. Fuller
1981, Open-File Report 81-644
Biological sampling was carried out during 1976-78 in five streams in the southeastern Uinta Basin, Utah and Colorado, in order to provide baseline water-quality data for an area of potential oil-shale development. The biological activity in the streams sampled generally is limited by physical factors more so than by chemical...

Simulated interactions between the proposed Narrows Reservoir and the water-table aquifer along the South Platte River, Morgan County, Colorado
Alan W. Burns
1981, Water-Resources Investigations Report 80-119
A computer model, including a ground-water-flow component and a mass balance reservoir-operations component, was developed to simulate the proposed Narrows Reservoir and the adjacent alluvial aquifer of the South Platte River, Morgan County, Colo. This model, using a weekly time step, simulated the transient interactions of these two systems for...
Hydrology and the effects of industrial pumping in the Nikiski area, Alaska
Gordon L. Nelson
1981, Open-File Report 81-685
Ground-water consumption for industrial use at Nikiski increased from about 1 million gallons per day in 1968 to 4.2 million gallons per day in 1979. Water managers and local citizens are concerned that industrial pumping may reduce the esthetic and recreational value of local lakes. Some lake levels have declined...
Land application of domestic wastewater in Florida--statewide assessment of impact on ground-water quality
Bernard J. Franks
1981, Water-Resources Investigations Report 81-3
In Florida domestic waste water is being applied to the land for disposal and reuse. State and Federal regulations favor land-application methods over other advanced waste water treatment practices. Despite the increasing use of this alternative technology, little is known about localized effects on groundwater quality. This report documents the...
Predicted effects on ground water of construction of Divide Cut section, Tennessee-Tombigbee Waterway, northeastern Mississippi, using a digital model
Mark S. McBride

The need for a water-tube tiltmeter and the details of its operation were covered by Eaton [1] in 1959. Since that time more modern instrumentation has allowed modification and further development beyond the basic single-tube fluid tiltmeter with a mechanical surface sensor. A number of instruments are discussed in connection...

Bedded Precambrian iron deposits of the Tobacco Root Mountains, southwestern Montana
H. L. James
1981, Professional Paper 1187
Bedded deposits of iron-formation are minor components of the thoroughly metamorphosed and deformed Precambrian rocks that make up the core of the Tobacco Root Mountains. The rocks are Archean in age; they predate a major Precambrian orogeny that affected all of southwestern Montana about 2,750 m.y. ago. The principal bed...
