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...
Aquifer systems in the Great Basin region of Nevada, Utah, and adjacent states: A study plan
James R. Harrill, Alan H. Welch, David E. Prudic, James M. Thomas, Rita L. Carman, Russell W. Plume, Joseph S. Gates, James L. Mason
1983, Open-File Report 82-445
The Great Basin Regional Aquifer Study includes about 140,000 square miles in parts of Nevada, Utah, California, Idaho, Oregon, and Arizona. Within that area, 240 hydrographic areas occupy structural depressions formed primarily by basin-and-range faulting. The principal aquifers are in basin- fill deposits; however, permeable carbonate rocks underlie valleys in...
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...
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...
Water-level changes in the high plains regional aquifer, northwestern Oklahoma, predevelopment to 1980
J.S. Havens
1983, Water-Resources Investigations Report 83-4073
During 1978, the U.S. Geological Survey began a 5-year study of the High Plains regional aquifer system to provide hydrologic information for evaluation of the effects of long-term development of the aquifer and to develop computer models for prediction of aquifer response to alternative changes in ground-water management (Weeks, 1978)....
Automatic dilution gaging of rapidly varying flow
M.D. Duerk
1983, Water-Resources Investigations Report 83-4088
It is often difficult to obtain discharge ratings at urban gaging stations. This report presents the results of using an automated constant-rate dyedilution technique to measure discharge at two sites in Madison, Wisconsin. The sites selected have well-defined stage-discharge ratings, developed during previous hydrologic studies. One site has a 60-inch...
Hydraulic conductivity, specific yield, and pumpage — High Plains aquifer system, Nebraska
Robert A. Pettijohn, Hsiu-Hsiung Chen
1983, Water-Resources Investigations Report 82-4014
Hydrologic data used to evalute the ground-water potential of the High Plains aquifer system in Nebraska are presented on maps showing the hydraulic conductivity and specific yield of the aquifer system and the volume and distribution of water pumped for irrigation from the aquifer system during 1980. The High Plains...
Identification and classification of perennial streams of Arkansas
R. A. Hunrichs
1983, Water-Resources Investigations Report 83-4063
Perennial streams are identified in a map and classified according to the relative magnitude of their 7-day, 10-year low flows. Perennial streams are identified for the entire State of Arkansas with the exception of the Mississippi Alluvial Plain. Also presented are the 7-day, 10-year low flow values at continuous-record and...
Application of remote-sensing techniques to hydrologic studies in selected coal-mined areas of southeastern Kansas
J. F. Kenny, J. R. McCauley
1983, Water-Resources Investigations Report 83-4007
Disturbances resulting from intensive coal mining in the Cherry Creek basin of southeastern Kansas were investigated using color and color-infrared aerial photography in conjunction with water-quality data from simultaneously acquired samples. Imagery was used to identify the type and extent of vegetative cover on strip-mined lands and the extent and...
Hydrology of the Ogallala aquifer in Ford County, southwestern Kansas
J. M. Spinazola, M.T. Dealy
1983, Water-Resources Investigations Report 83-4226
The rapid increase of ground-water withdrawal has caused concern over the future use of the Ogallala aquifer, the principal source of water in Ford County, in southwestern Kansas. Saturated portions of deposits of Tertiary and Quaternary age--excluding the Arkansas River alluvium--form the Ogallala aquifer. Saturated thickness of the Ogallala ranged...
Nevada - basic data for thermal springs and wells as recorded in Geotherm; Part A
James D. Bliss
1983, Open-File Report 83-433-A
GEOTHERM, a computerized information system now off-line, was used to maintain data on the geology, geochemistry and hydrology of geothermal sites primarily within the United States. The system was proposed at the First Geothermal Implementation Conference in New Zealand in 1974 (Swanson, 1977) and was active until 1983. The primary...
Hydrology and subsidence potential of proposed coal-lease tracts in Delta County, Colorado
Tom Brooks
1983, Water-Resources Investigations Report 83-4069
Potential subsidence from underground coal mining and associated hydrologic impacts were investigated at two coal-lease tracts in Delta County, Colorado. Alteration of existing flow systems could affect water users in the surrounding area. The Mesaverde Formation transmits little ground water because of the neglibile transmissivity of the 1,300 feet of...
Hydrology of the Little Androscoggin River Valley aquifer, Oxford County, Maine
D. J. Morrissey
1983, Water-Resources Investigations Report 83-4018
The Little Androscoggin River valley aquifer, a 15-square-mile sand and gravel valley-fill aquifer in southwestern Maine, is the source of water for the towns of Norway, Oxford, and South Paris. Estimated inflows to the aquifer during the 1981 water year were 16.4 cubic feet per second from precipitation directly on...
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...
Reconnaissance of surface-water resources in the Togiak River basin, southwestern Alaska, 1980 and 1982
D.R. Kernodle, R.R. Squires, J.M. Childers
1983, Water-Resources Investigations Report 83-4170
Data collected during August and September 1980 and March 1982 describe hydrologic characteristics of the Togiak River and its tributaries. Surface waters are generally cold and clear, have significant wilderness recreation values, and provide outstanding salmon habitat. Late summer unit runoff ranged from 2.3 to 8.1 cubic feet per second...
