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....
Geohydrology and model analysis of the stream-aquifer system along the Arkansas River in Kearny and Finney counties, southwestern Kansas
L. E. Dunlap, Richard J. Lindgren, C. G. Sauer
1983, Open-File Report 83-222
A study was made, in cooperation with the Division of Water Resources, Kansas State Board of Agriculture, to determine geohydrologic conditions in an area comprising nearly 850,000 acres along the Arkansas River valley in Kearny and Finney Counties, southwestern Kansas. The Arkansas River meanders atop and interacts hydraulically with the...
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...
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...
Hydrology of an abandoned coal-mining area near McCurtain, Haskell County, Oklahoma
L. J. Slack
1983, Water-Resources Investigations Report 83-4202
Water quality was investigated from October 1980 to May 1983 in an area of abandoned coal mines in Haskell county, Oklahoma. Bedrock in the area is shale, siltstone, sandstone, and the McAlester (Stigler) and Hartshorne coals of the McAlester Formation and Hartshorne Sandstone of Pennsylvanian age. The two coal beds,...
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...
Geohydrologic data for test well UE-25bH, Nevada Test Site, Nye County, Nevada
D.H. Lobmeyer, M.S. Whitfield, R.G. Lahoud, Laura Bruckheimer
1983, Open-File Report 83-855
Data were collected to determine the hydraulic characteristics of rocks penetrated in test well UE-25b number 1. This well is one of a series of test wells drilled in and near the southwestern part of the Nevada Test Site in a program conducted in cooperation with the U.S. Department of...
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...
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 resources of the Truk Islands
Otto Van der Brug
1983, Water-Resources Investigations Report 82-4082
The Truk Islands, part of the Caroline Islands in the western Pacific, consist of 19 volcanic islands and about 65 coral islets. The volcanic islands and some of the coral islets are scattered in an 820-square-mile lagoon enclosed by a 125-mile long barrier reef. Moen, although not the largest, is...
