Chemical analyses of stream deposits in the West Pioneer Mountains, Beaverhead County, Montana
David F. Siems, Eric P. Welsch, Wendy S. Speckman
1980, Open-File Report 80-309
The U.S. Geological Survey commenced a mineral-resource assessment of the West Pioneer Mountains, Montana in 1970. The study consists of coordinated geological, geochemical, and geophysical studies with the objective of evaluating the potential for mineral deposits in the area. The geochemical survey consists of the collection of bulk stream sediments...
Ground-water quality and data on wells and springs in Pennsylvania: Volume II, Susquehanna and Potomac River basins
Harry E. Koester, Denise R. Miller
1980, Open-File Report 81-329
Volume II of the Ground-Water Quality and Data on Wells and Springs in Pennsylvania presents ground-water quality and physical data on about 1,400 wells and springs in the Susquehanna and Potomac River basins in Pennsylvania. Locations are shown on site-location maps derived from the hydrologic unit map. Codes showing the...

The runoff filled Lake Pleasant and resulted in the largest release--66,600 cubic feet per second--from the reservoir since it was built in 1927; the maximum...
Finite-difference model to simulate the areal flow of saltwater and fresh water separated by an interface
James W. Mercer, S. P. Larson, Charles R. Faust
1980, Open-File Report 80-407
Model documentation is presented for a two-dimensional (areal) model capable of simulating ground-water flow of salt water and fresh water separated by an interface. The partial differential equations are integrated over the thicknesses of fresh water and salt water resulting in two equations describing the flow characteristics in the areal...
