Ground-water hydrology before, during, and after coal strip mining of a small watershed in Coshocton County, Ohio
A. C. Razem
1983, Water-Resources Investigations Report 83-4155
Ground-water conditions before, during, and after surface mining of a small watershed are described as part of a study to determine the effects of mining on hydrologic systems. The watershed was underlain by stratified sedimentary rocks containing three aquifers. The top and middle aquifers were perched above clay beds that...
Limnological study of Shasta Lake, Shasta County, California, with emphasis on the effects of the 1977 drought
S.A. Rettig, Gilbert C. Bortleson
1983, Water-Resources Investigations Report 82-4081
An intensive limnological study of Shasta Lake was made in conjunction with the California Department of Water Resources during the 1977 drought. Water-quality data were collected from March 1977 through September 1978 at six lake stations and four lake tributary stations. Data collected during and after the drought were compared....
A statistical summary of data from the U.S. Geological Survey's national water quality networks
R. A. Smith, R. B. Alexander
1983, Open-File Report 83-533
The U.S. Geological Survey Operates two nationwide networks to monitor water quality, the National Hydrologic Bench-Mark Network and the National Stream Quality Accounting Network (NASQAN). The Bench-Mark network is composed of 51 stations in small drainage basins which are as close as possible to their natural state, with no human...
Potentiometric surfaces on Long Island, New York -- A bibliography of maps
D. A. Smolensky
1983, Open-File Report 84-70
Historic water-level records form a major basis for ground-water investigations and water-management decisions on Long Island. Potentiometric-surface maps, one of the major sources of historic data, are scattered within the literature or are available only through the publisher or sponsoring agency. This report presents a comprehensive list of available water-table...
Literature assessment of the Charlotte Harbor estuarine system and surrounding area, Southwest Florida
Yvonne E. Stoker, George A. Karavitis
1983, Open-File Report 83-127
The Governor of Florida established the Charlotte Harbor Resource Planning and Management committee to recommend the course of action Florida should take in planning for potential growth in the rapidly growing area surrounding Charlotte Harbor. In May 1981, the U.S. Geological Survey began a planning study to determine detailed hydrologic...
Water resources of the Rattlesnake Butte area, a site of potential lignite mining in west-central North Dakota
W.F. Horak
1983, Water-Resources Investigations Report 83-4228
In much of western North Dakota, minable lignite beds and associated sand beds are valuable local aquifers. Strip mining disrupts the aquifers and could significantly impact the local hydrology, imposing hardships on local residents. This comprehensive water-resources study of a 147-square-mile coal area in west-central North Dakota was done to...
Hydrology of the Wibaux-Beach lignite deposit area, eastern Montana and western North Dakota
W.F. Horak
1983, Water-Resources Investigations Report 83-4157
The Paleocene Harmon lignite, the principal commercial bed of the Wihaux-Beach deposit, underlies at least 150 square miles along the Montana-North Dakota border. An estimated 1 billion tons of strippable reserves underlies about 50 square miles. The Harmon lignite bed also is the most consistently occurring shallow aquifer in the...
Hydrology of the Newberry Volcano caldera, Oregon
E.A. Sammel, R. W. Craig
1983, Water-Resources Investigations Report 83-4091
Precipitation in the Newberry Caldera is very nearly in balance with evaporation, evapotranspiration, and streamflow. Calcium, magnesium, and bicarbonate ions predominate in the more dilute ground and surface water. Thermal waters from springs and wells have concentrations of 900 milligrams per liter or more and are characterized by high concentrations...
Bryozoan fauna of the Upper Clays Ferry, Kope, and Lower Fairview formations (Edenian, Upper Ordovician) at Moffett Road, northern Kentucky
Olgerts L. Karklins
1983, Open-File Report 83-21
The geology, water movement, and sediment characteristics in the upstream part of the Spring River basin have been appraised, to assist the U.S. EPA in their study of dioxin contamination in the area. The U.S. Environmental Protection Agency has confirmed that the dioxin compound, TCDD (2,3,7 ,8-tetrachlorodibenzo-p-dioxin), is present in...
Instrumentation used for hydraulic testing of potential water-bearing formations at the Waste Isolation Pilot Plant site in southeastern New Mexico
J.A. Basler
1983, Open-File Report 83-144
Requirements for testing hydrologic test wells at the proposed Waste Isolation Pilot Plant near Carlsbad, New Mexico, necessitated the use of inflatable formation packers and pressure transducers. Observations during drilling and initial development indicated small formation yields which would require considerable test times by conventional open-casing methods. A pressure-monitoring system...
Potential effects of surface coal mining on the hydrology of the Greenleaf-Miller area, Ashland coal field, southeastern Montana
G. W. Levings
1983, Water-Resources Investigations Report 82-4101
The Greenleaf-Miller area of the Ashland coal field contains reserves of Federal coal that have been identified for potential lease sale. A hydrologic study was conducted in the potential lease area in 1981 to describe the existing hydrologic system and to assess potential impacts of surface coal mining on local...
General hydrology and external sources of nutrients affecting Pine Lake, King County, Washington
N. P. Dion, S. S. Sumioka, T. C. Winter
1983, Water-Resources Investigations Report 83-4057
An adjusted water budget prepared for Pine Lake, a candidate for lake-quality restoration, indicates that of approximately 790 acre-feet of water that enters the lake in a typical year, 410 acre-feet is from precipitation, 350 acre-feet is from surface inflow, and 30 acre-feet is from ground-water seepage. A nearly equal...
Hydrology of the Jasper (Miocene) Aquifer in the Southeast Texas coastal plain
E.T. Baker
1983, Open-File Report 83-677
The Jasper (Miocene) aquifer is one of several important hydrologic units in the Gulf Coastal Plain. Because the Jasper aquifer underlies shallower aquifers in many areas, regional water withdrawals from the Jasper are not significant; however, it is capable of yielding 3,000 gallons per minute (200 liters per second) or...
Technique for estimating depth of floods in Tennessee
C. R. Gamble
1983, Water-Resources Investigations Report 83-4050
Estimates of flood depths are needed for design of roadways across flood plains and for other types of construction along streams. Equations for estimating flood depths in Tennessee were derived using data for 150 gaging stations. The equations are based on drainage basin size and can be used to estimate...
