Modifications and corrections to the finite-difference model for simulation of three-dimensional ground-water flow
L.J. Torak
1982, Water-Resources Investigations Report 82-4025
This report describes modifications incorporated into the finite-difference model for simulation of groundwater flow in three dimensions. These modifications extend the application of this model to simulations involving head-dependent sources and sinks (i.e., rivers, evapotranspiration, and springs or drains). Other modifications are made that enhance the iterative-solution process of the...

1982, IMAP 1311
The rocks and deposits within the Wenatchee quadrangle can be grouped into six generalized units: (1) Precambrian(?) Swakane Biotite Gneiss in the northeastern part of the quadrangle and the probable Jurassic low-grade metamorphic suite, mostly composed of the Easton Schist, in the southwestern part; (2) the Mesozoic Ingalls Tectonic Complex;...
Reconnaissance geologic map and mineral resource potential of the Gearhart Mountain Wilderness and Roadless Area (6225), Lake and Klamath counties, Oregon
George W. Walker, James Ridenour
1982, Miscellaneous Field Studies Map 1367
The Gearhart Mountain Wilderness, Lake and Klamath Counties, Oreg., is devoid of mines and mineral prospects and there are no known mining claims within the area. Furthermore, the results of this mineral appraisal indicate that there is little likelihood that commercial deposits of metallic minerals will be found in the...

Hydrology of the Prairie Dog Creek drainage basin, Rosebud and Big Horn Counties, Montana
N. E. McClymonds
1982, Water-Resources Investigations Report 81-37
The Prairie Dog Creek drainage basin in southeastern Montana was investigated during 1978-79 to assess the surface-water and ground-water resources and the quality of water in an area having coal-mining potential. The area, a 24.2-square-mile basin, is located 30 miles southwest of Ash-land, Montana. The principal mineable coal is the...

1982, Open-File Report 82-434
Flood stages and peak discharges are described for 13 sites on streams in West Windsor Township, Mercer County, New Jersey, and surrounding areas, collected by the U.S. Geological Survey through the 1981 water year. Included are descriptions and elevations of floodmarks at 30 sites located by the West Windsor Township...
Quality of streams in the Bull Mountains region, south-central Montana
J. R. Knapton
1982, Water-Resources Investigations Report 82-2
In October 1977, water-quality monitoring stations were established on five small streams that drain the Bull Mountains and also on the Musselshell River to document present water-quality conditions in a coal area of south-central Montana. Relatively static water-quality conditions exist throughout the annual flow cycle on the small streams but...

Appraisal of ground-water quality near wastewater-treatment facilities, Glacier National Park, Montana
Joe A. Moreland, Wayne A. Wood
1982, Water-Resources Investigations Report 82-4
Water-level and water-quality data were collected from monitoring wells at wastewater-treatment facilities in Glacier National Park. Five additional shallow observation wells were installed at the Glacier Park Headquarters facility to monitor water quality in the shallow ground-water system.Water-level, water-quality, and geologic information indicate that some of the initial monitoring wells...
Evaluation of a predictive ground-water solute-transport model at the Idaho National Engineering Laboratory, Idaho
