Hydrologic monitoring in the coal fields of central Utah, August 1978-September 1979
Gregory C. Lines, Gerald G. Plantz
1981, Open-File Report 81-138
Surface-water quantity and quality were observed at 12 gaging stations downstream from mined and lease areas in the Wasatch Plateau, Book Cliff's, and Emery coal fields in central Utah. Measurements of base flow were made at 52 additional sites in the region. The report describes the hydrologic setting of this...
Hydrologic studies of the U.S. Geological Survey in major coal-resource areas of Utah through 1980
Gregory C. Lines
1981, Open-File Report 81-216
Increased interest in coal has created greater interest in water, both for environmental and water-supply reasons. This report summarizes hydrologic studies conducted in and near the major coal fields of Utah (fig. 1) by the U.S. Geological Survey through 1980. It is intended as a reference for those people dealing...
A 10-year plan to study the aquifer system of Indian Wells Valley, California
Paul Lipinski, Darwin D. Knochenmus
1981, Open-File Report 81-404
Water needs of the population of Indian Wells Valley, Calif., must be met through further development of ground-water resources. Studies show that annual ground-water pumpage there has increased since 1945 and has exceeded mean annual recharge since 1966. Continued and increased stress on the aquifer system of the valley is...

Baseline studies of the feasibility and reliability of using animal behavior as a component in the prediction of earthquakes
Dale F. Lott, Benjamin L. Hart, Kenneth L. Verosub
1981, Open-File Report 81-378
This project was established to determine if it were possible to advance the state of the art in earthquake prediction by learning more about claims that unusual animal behavior was an earthquake precursor. We used intensive post-earthquake interview surveys to gather objective reports both of instances of unusual animal behavior...
Radionuclide concentrations in streams in the upper Blackfoot River basin, southeastern Idaho
Walton H. Low
1981, Open-File Report 81-142
Data on radionuclide concentrations in water and sediment material in the phosphate-mining area of the upper Blackfoot River basin were collected from May to October 1979. Maximum measured uranium and radium-226 concentrations dissolved in water were 3.7 micrograms per liter and 1.8 picocuries per liter , respectively. Maximum measured uranium...

Measured sections of the Browns Park Formation (Miocene) in Moffat County, Colorado, 1980
Stanley J. Luft, William L. Thoen
1981, Open-File Report 81-171
Eight partial sections of the Browns Park Formation of Miocene age were measured in Moffat County, northwestern Colorado, during the 1980 field season, as part of a study of the stratigraphy and depositional environments of the formation. These newly measured sections are intended to complement other surface sections of the...

Potentially favorable areas for large-yield wells in the Red River Formation and Madison Limestone in parts of Montana, North Dakota, South Dakota, Wyoming, and Nebraska
L.M. MacCary, E. M. Cushing, David L. Brown
1981, Open-File Report 81-220
The need for large quantities of energy has created interest in the Fort Union coal region of the Northern Great Plains. Extensive development of this coal, which may include onsite steam-power generation, gasification, liquefaction, and slurry-pipeline transport of the coal from this region, would place a heavy demand on the...
Map showing the potentiometric surface of the Magothy aquifer in southern Maryland, August 1980
Frederick K. Mack, Judith C. Wheeler, Stephen E. Curtin
1981, Open-File Report 81-633
This map is based on measurements made in a network of 77 observation wells. Highest levels of the potentiometric surface, 61 to 64 feet above sea level, were near the outcrop or subcrop of the aquifer in topographically high areas of Anne Arundel and northern Prince Georges Counties. The potentiometric...
State-discharge relations at dams on the Illinois and Des Plaines rivers in Illinois
Dean M. Mades
1981, Open-File Report 81-1009
Stage-discharge relations were developed for the Brandon Road Dam on the Des Plaines River and the Dresden Island, Marseilles, Starved Rock, Peoria, and La Grange Dams on the Illinois River. A t Brandon Road Dam, streamflow is regulated by the operation of tainter gates and headgates. Tainter gates are operated...
