Water-resources activities of the U.S. Geological Survey in Montana, October 1987 through September 1989
J. N. Thamke (compiler)
1989, Open-File Report 89-591
Water resources programs and activities of the U.S. Geological Survey in Montana consist principally of hydrological data collection and local, areal, or statewide hydrologic investigations. The work is supported by direct Federal funding, by transfer of funds from other Federal agencies, and by joint funding agreements with State or local...
Documentation of computer programs to compute and display pathlines using results from the U.S. Geological Survey modular three-dimensional finite-difference ground-water flow model
David W. Pollock
1989, Open-File Report 89-381
A particle tracking post-processing package was developed to compute three-dimensional path lines based on output from steady-state simulations obtained with the U.S. Geological Survey modular 3-dimensional finite difference groundwater flow model. The package consists of two FORTRAN 77 computer programs: (1) MODPATH, which calculates pathlines, and (2) MODPATH-PLOT, which presents...
Progress report on the ground-water, surface-water, and quality-of-water monitoring program, Black Mesa area, northeastern Arizona— 1988-89
R. J. Hart, J. P. Sottilare
1989, Open-File Report 89-383
The Black Mesa monitoring program in Arizona is designed to determine long-term effects on the water resources of the area resulting from withdrawals of groundwater from the N aquifer by the strip-mining operation of Peabody Coal Company. Withdrawals by Peabody Coal Company increased from 95 acre-ft in 1968 to 4...
Well installation and documentation, and ground-water sampling protocols for the pilot National Water-Quality Assessment Program
M. A. Hardy, P.P. Leahy, W.M. Alley
1989, Open-File Report 89-396
Several pilot projects are being conducted as part of the National Water Quality Assessment (NAWQA) Program. The purpose of the pilot program is to test and refine concepts for a proposed full-scale program. Three of the pilot projects are specifically designed to assess groundwater. The purpose of this report is...
Geology and water resources of Owens Valley, California
Kenneth J. Hollett, W.R. Danskin, W. F. McCaffrey, C.L. Walti
1989, Open-File Report 88-715
Owens Valley, a long, narrow valley located along the east flank of the Sierra Nevada in east-central California, is the main source of water for the city of Los Angeles. The city diverts most of the surface water in the valley into the Owens River-Los Angeles Aqueduct system, which transports...
Selected hydrologic data for Fountain Creek and Monument Creek basins, east-central Colorado
Gerhard Kuhn, Roderick F. Ortiz
1989, Open-File Report 88-705
Selected hydrologic data were collected during 1986, 1987, and 1988 by the U.S. Geological Survey for the Fountain Creek and Monument Creek basins, east-central Colorado. The data were obtained as part of a study to determine the present and projected effects of wastewater discharges on the two creeks. The data,...
Direct-current vertical electrical-resistivity soundings in the Lower Peninsula of Michigan
D.B. Westjohn, P.J. Carter
1989, Open-File Report 89-244
Ninety-three direct-current vertical electrical-resistivity soundings were conducted in the Lower Peninsula of Michigan from June through October 1987. These soundings were made to assist in mapping the depth to brine in areas where borehole resistivity logs and water-quality data are sparse or lacking. The Schlumberger array for placement of current...
Comparison of sediment transport formulas and computation of sediment discharges for the North Fork Toutle and Toutle rivers, near Mount St. Helens, Washington
S.E. Hammond
1989, Open-File Report 88-463
This preliminary report presents results of computations using twelve different sediment discharge formulas along with data from two data collection sites in the Toutle River basin. Output from six bed material discharge formulas and six bedload discharge formulas was considered. The results of the computations are presented graphically for comparison...
Water-quality data for selected wells and drains in the Oakes study area, south-central North Dakota, December 1986 through September 1987
James D. Wald, C.S. Helgesen, M.C. Pokladnik
1989, Open-File Report 89-63
Operation of the Garrison Diversion Unit in North Dakota will divert water from the Missouri River near Lake Audubon into the upper James River basin (fig. 1). The diverted water will augment flows in the James River sufficiently to permit expanded irrigation and to provide additional water supplies for municipal...
Effects of river discharge and high-tide stage on salinity intrusion in the Weeki Wachee, Crystal, and Withlacoochee River estuaries, southwest Florida
D. K. Yobbi, L. A. Knochenmus
1989, Water-Resources Investigations Report 88-4116
The Weeki Wachee, Crystal, and Withlacoochee Rivers are coastal streams flowing into the Gulf of Mexico that may be affected by either future surface water or groundwater withdrawals. Reduction of river discharge will affect the upstream extent of saltwater intrusion in the rivers; however, under certain reduced low-flow discharges, the...
Streamflow and water-quality data for Meadow Run basin, Fayette County, Pennsylvania, December 1987 - November 1988
K. M. Kostelnik, E.C. Witt
1989, Open-File Report 89-404
Streamflow and water-quality data were collected throughout the Meadow Run basin, Fayette County, Pennsylvania, from December 7, 1987 through November 15, 1988, to determine the prevailing quality of surface water over a range of hydrologic conditions. This data will assist the Pennsylvania Department of Environmental Resources during its review of...
Streamflow and water-quality data for Little Scrubgrass Creek basin, Venango and Butler counties, Pennsylvania, December 1987 - November 1988
K. M. Kostelnik, R.R. Durlin
1989, Open-File Report 89-577
Streamflow and water-quality data were collected throughout the Little Scrubgrass Creek basin, Venango and Butler Counties, Pennsylvania, from December 1987 to November 1988, to determine the prevailing quality of surface water throughout the basin. This data will assist the Pennsylvania Department of Environmental Resources during its review of coal mine...
Selected quality assurance data for water samples collected by the US Geological Survey, Idaho National Engineering Laboratory, Idaho, 1980 to 1988
