Ground-water data for Michigan 1979
G.C. Huffman
1980, Open-File Report 80-1212
The purpose of this report is to make available the 1979 records of water levels and related data for the principal aquifers of the State. This report is written for municipalities, industries, institutions, consultants, drillers, hydrologists, and other people interested in the ground-water resources....
Ground-water quality and data on wells and springs in Pennsylvania: Volume II, Susquehanna and Potomac River basins
Harry E. Koester, Denise R. Miller
1980, Open-File Report 81-329
Volume II of the Ground-Water Quality and Data on Wells and Springs in Pennsylvania presents ground-water quality and physical data on about 1,400 wells and springs in the Susquehanna and Potomac River basins in Pennsylvania. Locations are shown on site-location maps derived from the hydrologic unit map. Codes showing the...
Hydrogeochemistry and simulated solute transport, Piceance Basin, northwestern Colorado
Stanley G. Robson, George J. Saulnier
1980, Open-File Report 80-72
Oil-shale mining activities in Piceance basin in northwestern Colorado could adversely affect the ground- and surface-water quality in the basin. This study of the hydrology and geochemistry of the area used groundwater solute-transport-modeling techniques to investigate the possible impact of the mines on water quality. Maps of the extent and...
Ground water of coal deposits, Bay County, Michigan
J. R. Stark, Michael G. McDonald
1980, Open-File Report 80-591
A coal deposit in Bay County, Mich., typical of Pennsylvanian-coal deposits in the State, was studied to determine the degree to which hydrologic factors might affect future coal mining. The coal deposit, which averages about 0.5 meters in thickness, lies 50 meters below land surface. It is part of a...
Planning and design of studies for river-quality assessment in the Truckee and Carson River basins, California and Nevada
Jon O. Nowlin, W. M. Brown, L. H. Smith, R.J. Hoffman
1980, Open-File Report 80-435
The objectives of the Geological Survey 's river-quality assessment in the Truckee and Carson River basins in California and Nevada are to identify the significant resource management problems; to develop techniques to assess the problems; and to effectively communicate results to responsible managers. Six major elements of the assessment to...
Hydrology of Jumper Creek Canal basin, Sumter County, Florida
Warren Anderson
1980, Open-File Report 80-208
In 1960, floods caused extensive damage to agribusiness in Jumper Creek Canal basin. In 1962, a plan was developed for a proposed project to reduce the threat of floods. In 1976, a study of the hydrology of the basin was proposed to help evaluate this plan and to serve as...
Hydrologic budget for Eagle Lake near Willmar, Minnesota
C. F. Myette
1980, Open-File Report 80-163
Eagle Lake occupies 890 acres of a 9,000-acre watershed in central Minnesota. Because of its proximity to Willmar, many homes and summer cabins have been built around the lake. Presently (1978), the shore is more than 90 percent developed. One effect of this development is accelerated eutrophication, most commonly shown...
Ground-water quality in North Idaho
D. J. Parliman, Harold R. Seitz, Michael L. Jones
1980, Open-File Report 80-596
From July 1977 to May 1978, water samples were collected from 116 wells north of the Palouse River in Idaho to define water-quality conditions, on a reconnaissance level, in major aquifers. Geologic and hydrologic data were combined with water-quality data to develop an understanding of factors affecting present and future...
Hydrologic data for runoff studies on small drainage areas, West Virginia Department of Highways Research Project 16
Gerald S. Runner
1980, Open-File Report 80-560
Station listings, basin and flow characteristics tables, and annual maximum discharges are presented for stations in West Virginia, Maryland, and Virginia that were used to develop flood-frequency relations for West Virginia. Also presented are figures showing approximate station location and areal coverage for both longterm and short-term stations that were...
Hydrology of the Chicod Creek basin, North Carolina, prior to channel improvements
Clyde E. Simmons, Mary C. Aldridge
1980, Open-File Report 80-680
Extensive modification and excavation of stream channels in the 6-square mile Chicod Creek basin began in mid-1979 to reduce flooding and improve stream runoff conditions. The effects of channel improvements on this Coastal Pain basin 's hydrology will be determined from data collected prior to, during, and for several years...
Ground-water resources investigation in the Amran Valley, Yeman Arab Republic
G. Chase Tibbitts, James Aubel
1980, Open-File Report 80-774
A program of hydrologic studies and exploratory drilling was conducted intermittently between 1974 and 1978 to evaluate the water-bearing properties of the unconsolidated alluvial sediments and associated rocks in the semi-arid Amran Valley basin, an 800-square-kilometer area in north-central Yemen Arab Republic. Inventory data from 395 wells were compiled, observation...
Ground-water data for the Riley and Andrews Resource Areas, southeastern Oregon
Paul J. Townley, Constance M. Soja, W.C. Sidle
1980, Open-File Report 80-419
Appraisals of the resources of selected management areas in eastern Oregon are being made by the U.S. Bureau of Land Mangement. To provide needed hydrologic information, the Bureau of Land Management requested the U.S. Geological Survey to inventory ground-water data for the Riley and Andrews Resource Areas. The inventory included...
Ground-water hydrology of the Sagebrush Flat area as related to the discharge of Rattlesnake Springs, Grant and Douglas counties, Washington
K.L. Walters
1980, Open-File Report 79-1530
In 1978, the U.S. Geological Survey, in cooperation with the State of Washington Department of Ecology, investigated the hydrology of the Sagebrush Flat area as it relates to Rattlesnake Springs. Rattlesnake Springs and all known wells on Sagebrush Flat obtain water from basalt aquifers. The wells tap aquifers at or...
Effects of the proposed Prosperity Reservoir on ground water and water quality in lower Center Creek basin, Missouri
Wayne R. Berkas, James H. Barks
1980, Water-Resources Investigations Report 80-88
Effects of the proposed Prosperity Reservoir on ground water and water quality in lower Center Creek basin depend partly on the effectiveness of Grove Creek as a hydrologic boundary between the reservoir site and the Oronogo-Duenweg mining belt. Results of two dye traces indicate that Grove Creek probably is not...
A water-quality monitoring network for Vallecitos Valley, Alameda County, California
C. D. Farrar
1980, Water-Resources Investigations Report 80-59
A water-quality monitoring network is proposed to detect the presence of and trace the movement of radioisotopes in the hydrologic system in the vicinity of the Vallecitos Nuclear Center. The source of the radioisotopes is treated industrial wastewater from the Vallecitos Nuclear Center that is discharged into an unnamed tributary...
Appraisal of the water resources of the Big Sioux aquifer, Brookings, Deuel, and Hamlin counties, South Dakota
Neil C. Koch
1980, Water-Resources Investigations Report 80-100
The Big Sioux aquifer in Brookings, Deuel, and Hamlin Counties, South Dakota, has been extensively developed and in some areas discharge, principally by wells, from the aquifer may be exceeding recharge to the aquifer.A finite-difference method digital model was used to simulate steady-state conditions of the Big Sioux aquifer. Average...
Development of a digital model of ground-water flow in deeply weathered crystalline rock, Chester County, Pennsylvania
