Effects of artificial recharge on the Ogallala aquifer, Texas
Richmond Flint Brown, W.S. Keys
1985, Water Supply Paper 2251
Four recharge tests were conducted by injecting water from playa lakes through wells into the Ogallala Formation. Injection was by gravity flow and by pumping under pressure. At one site, 34-acre feet of water was injected by gravity and produced a significant increase in yield of the well. At a...
Geohydrology and water resources of the Papago Farms-Great Plain area, Papago Indian Reservation, Arizona, and the upper Rio Sonoyta area, Sonora, Mexico
Kenneth J. Hollett
1985, Water Supply Paper 2258
The Papago Farms-Great Plain and upper Rio Sonoyta study area includes about 490 square miles in south-central Arizona and north-central Sonora, Mexico. The area is characterized by a broad, deep, sediment-filled basin bounded by low, jagged fault-block mountains. The climate is arid to semiarid. The climate and abundant ground water...
Ground-water resources and potential hydrologic effects of surface coal mining in the northern Powder River basin, southeastern Montana
Steven E. Slagle, Barney D. Lewis, Roger W. Lee
1985, Water Supply Paper 2239
The shallow ground-water system in the northern Powder River Basin consists of Upper Cretaceous to Holocene aquifers overlying the Bearpaw Shale--namely, the Fox Hills Sandstone; Hell Creek, Fort Union, and Wasatch Formations; terrace deposits; and alluvium. Ground-water flow above the Bearpaw Shale can be divided into two general flow patterns....
Digital models of ground-water flow in the Cape Cod aquifer system, Massachusetts
John H. Guswa, Denis R. LeBlanc
1985, Water Supply Paper 2209
The Cape Cod aquifer system was simulated with three-dimensional finite-difference ground-water-flow models. Five areas were modeled to provide tools that can be used to evaluate the hydrologic impacts of regional water development and waste disposal. The model boundaries were selected to represent the natural hydrologic boundaries of the aquifer. The...
Selected papers in the hydrologic sciences, 1985; May 1985
Seymour Subitzky, editor(s)
1985, Water Supply Paper 2270
The University of Minnesota, the Minnesota Geological Survey, and the U.S. Geological Survey are studying the feasibility of storing water at a temperature of 150 degrees Celsius in the Franconia-Ironton-Galesville aquifer. The Aquifer Thermal-Energy Storage project has a doublet-well design with a well spacing of approximately 250 meters. One well...
Relation between ground-water quality and mineralogy in the coal-producing Norton Formation of Buchanan County, Virginia
John D. Powell, Jerry D. Larson
1985, Water Supply Paper 2274
The geochemical processes controlling ground-water chemistry in the coal-producing strata of southwestern Virginia include hydrolysis of silicates, dissolution of carbonates, oxidation of pyrite, cation exchange, and precipitation of secondary minerals, kaolinite and goethite. Core material from the Norton Formation of the Pennsylvania Period is composed of slightly more than one-half...
Study and interpretation of the chemical characteristics of natural water
John David Hem
1985, Water Supply Paper 2254
The chemical composition of natural water is derived from many different sources of solutes, including gases and aerosols from the atmosphere, weathering and erosion of rocks and soil, solution or precipitation reactions occurring below the land surface, and cultural effects resulting from human activities. Broad interrelationships among these processes and...
Chemical and physical characteristics of water and sediment in Scofield Reservoir, Carbon County, Utah
Kidd M. Waddell, D.W. Darby, S.M. Theobald
1985, Water Supply Paper 2247
Evaluations based on the nutrient content of the inflow, outflow, water in storage, and the dissolved-oxygen depletion during the summer indicate that the trophic state of Scofield Reservoir is borderline between mesotrophic and eutrophic and may become highly eutrophic unless corrective measures are taken to limit nutrient inflow.Sediment deposition in...
The stream-gaging program in South Dakota
J.R. Little, D.K. Matthews
1985, Open-File Report 85-564
This report documents the results of a study of the uses, funding, and availability of the streamflow information program in South Dakota. In 1983, 107 continuous-record surface-water gaging stations were being operated in South Dakota on a budget of $607,050. Data from most stations have multiple uses. Data uses and...
The Georgia Water-Use Program
Julia L. Fanning
1985, Open-File Report 85-481
WHY COLLECT WATER-USE INFORMATION? Water used in Georgia increased from 5,560 to 6,765 million gallons per day (22 percent) between 1970 and 1980. In 1970 the population of Georgia was about 4,600,000. By 1980 it had rcached an estimated 5,500,000, a 20-percent increase. The amount of irrigated land in the State...
Water-resources activities of the U.S. Geological Survey in Wyoming; fiscal year 1985
S. L. Green (compiler)
1985, Open-File Report 85-562
This report contains lists and location maps of streamflow and reservoir stations, water quality stations, sediment stations, and groundwater observation wells where data are currently being collected. Water resources appraisal projects in Wyoming are described, including many that are related to development of energy resources. The general locations of most...
