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...
Integrated uranium system in the Marysvale volcanic field, west-central Utah
Thomas August Steven, Charles G. Cunningham, Michael N. Machette
1980, Open-File Report 80-524
Uranium in the Marysvale volcanic field is known to occur in several geologic environments, and is hypothesized to occur in others. Together the known and hypothetical occurrences range from a source in rhyolite magma, through porphyry-type deposits, hydrothermal vein deposits, dispersed hydrothermal deposits, and after transport in ground and surface...
A one-dimensional, steady-state, dissolved-oxygen model and waste-load assimilation study for Wabash River, Huntington County, Indiana
Charles G. Crawford, William G. Wilber, James G. Peters
1980, Open-File Report 80-75
The Indiana State Board of Health is developing a State water-quality management plan that includes establishing limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in the Wabash River in Huntington County, Ind., was used to predict alternatives for future waste loadings that would be...
A one-dimensional, steady-state, dissolved-oxygen model and waste-load assimilation study for Duck Creek, Madison, Tipton, and Hamilton counties, Indiana
Charles G. Crawford, William G. Wilber, James G. Peters
1980, Open-File Report 80-156
The Indiana State Board of Health is developing a State water-quality plan that includes establishing limits for wastewater effluents discharged into Indiana streams. A digital model calibrated to conditions in Duck Creek was used to develop alternatives for future waste loadings that would be compatible with Indiana stream water-quality standards...
Preliminary map showing freshwater heads for the Red River Formation, Bighorn Dolomite, and equivalent rocks of Ordovician age in the Northern Great Plains of Montana, North Dakota, South Dakota, and Wyoming
W. Roger Miller, S.A. Strausz
1980, Open-File Report 80-730
A map showing freshwater heads for the Ordovician Red River Formation, Bighorn Dolomite, and equivalent rocks has been prepared as part of a study to determine the water-resources potential of the Mississippian Madison Limestone and associated rocks in the Northern Great Plains of Montana, North and South Dakota, and Wyoming....
Preliminary map showing freshwater heads for the Mission Canyon and Lodgepole limestones and equivalent rocks of Mississippian age in the Northern Great Plains of Montana, North Dakota, South Dakota, and Wyoming
W. Roger Miller, S.A. Strausz
1980, Open-File Report 80-729
A potentiometric-surface map showing freshwater heads for the Mission Canyon and Lodgepole Limestones of Mississippian age has been prepared as part of a study to determine the water-resources potential of the Mississippian Madison Limestone and associated rocks in the Northern Great Plains of Montana, North and South Dakota, and Wyoming....
Waterfowl status report, 1976
1980, Special Scientific Report - Wildlife 227
This report contains information from the 1975-76 midwinter waterfowl survey, the 1976 waterfowl breeding population and production surveys, and the waterfowl harvest surveys for the 1975-76 hunting season. This information was provided by the U.S. Fish and Wildlife Service, the Canadian Wildlife Service, and various cooperating State wildlife conservation agencies....

Summary appraisals of the nation's ground-water resources – Caribbean region
Fernando Gómez-Gómez, James E. Heisel
1980, Professional Paper 813-U
The Caribbean Region consists of the Commonwealth of Puerto Rico (8,990 km2 (square kilometers)) and the U.S. Virgin Islands (350 km2). The mean annual precipitation varies locally from a high of 5,000 mm (millimeters) to a low of 730 mm. Maximum precipitation occurs within the peaks of Sierra de Luquillo,...
Food of alewives, yellow perch, spottail shiners, trout-perch, and slimy and fourhorn sculpins in southeastern Lake Michigan
LaRue Wells
1980, Technical Paper 98
Stomachs of 1,064 alewives (Alosa pseudoharengus), 1,103 yellow perch (Perca flavescens), 246 spottail shiners (Notropis hudsonius), 288 trout-perch (Percopsis omiscomaycus), 454 slimy sculpins (Cottus cognatus), and 562 fourhorn sculpins (Myoxocephalus quadricornis) from Lake Michigan were examined for food contents. Fish were sampled primarily from March to November and nearly all...
