Water-quality conditions of inflow, outflow, and impounded water at Rathbun Reservoir, Iowa, Clinton and Pomona Lakes, Kansas, and Harlan County Reservoir, Nebraska, May through August 1993
A.C. Ziegler, P.P. Rasmussen, M.D. Carlson, D. A. Hargadine
1995, Open-File Report 95-472
During May through August 1993, water-quality samples were collected twice from selected sites in Rathbun Reservoir, Iowa, Clinton and Pomona Lakes, Kansas, and Harlan County Reservoir, Nebraska. Samples were analyzed for selected physical and chemical properties, bacteria, major ions, nutrients, selected metals, total organic carbon, selected herbicides, and chlorophyll-a and...
Hydrologic effects associated with the January 17, 1994 Northridge, California, earthquake
E.G. Quilty, C. D. Farrar, D. L. Galloway, S. N. Hamlin, R. J. Laczniak, E.A. Roeloffs, M.L. Sorey, D.E. Woodcock
1995, Open-File Report 95-813
This report compiles hydrologic observations in southern California associated with the 1994 Mw = 6.7 Northridge, California earthquake. In southern California, the largest ground water level change was a drop of 52 cm at Crystalaire. Most of the steplike water-level changes recorded following the Northridge earthquake agreed in direction with...
Water-quality data for the Santa Clara-Calleguas hydrologic unit, Ventura County, California, October 1989 through December 1993
J. A. Izbicki, P. M. Martin, J.N. Densmore, D. A. Clark
1995, Open-File Report 95-315
More than 700 water samples were collected from 232 wells and 34 surface-water sites in the Santa Clara-Calleguas Hydrologic Unit, Ventura County, California, from October 1989 through December 1993 as part of the U.S. Geological Survey's Southern California Regional Aquifer-System Analysis study. Most samples were analyzed for major ions, nutrients,...
Numerical Simulation of Regional Changes in Ground-Water Levels and in the Freshwater-Saltwater Interface Induced by Increased Pumpage at Barbers Point Shaft, Oahu, Hawaii
William R. Souza, William Meyer
1995, Water-Resources Investigations Report 95-4206
The effect on the regional ground-water system of southern Oahu from increased pumpage at Barbers Point shaft was estimated by a numerical ground-water model developed for the Oahu Regional Aquifer Systems Analysis (RASA) study. The RASA model was updated by revising pumping and ground-water recharge data. Pumpage data used in...
Flow duration of Kentucky streams through 1990; historical and monthly flow characteristics, including the effects of reservoirs
K.J. Ruhl, R.J. Burns, G. R. Martin, D.P. Allgeier
1995, Open-File Report 95-353
This report presents flow-duration tables and plots for selected streamflow sites in Kentucky with three or more years of continuous record through 1990. Flow duration describes the frequency with which given streamflows are equalled or exceeded. The flow-duration tables were computed using daily mean discharge values for the entire period...
Water-quality characteristics of selected public recreational lakes and ponds in Connecticut
D. F. Healy, K.P. Kulp
1995, Water-Resources Investigations Report 95-4098
Reconnaissance limnological and lakebed-sediment surveys were conducted in Connecticut during 1989-91 by the U.S. Geological Survey, in cooperation with the Connecticut Department of Environmental Protec- tion, to evaluate water-quality characteristics of selected public recreational lakes and ponds in the State. Limnological surveys were conducted on 49 lakes and ponds selected...
Geochemical processes in ground water resulting from surface mining of coal at the Big Sky and West Decker Mine areas, southeastern Montana
D.W. Clark
1995, Water-Resources Investigations Report 95-4097
A potential hydrologic effect of surface mining of coal in southeastern Montana is a change in the quality of ground water. Dissolved-solids concen- trations in water in spoils aquifers generally are larger than concentrations in water in the coal aquifers they replaced; however, laboratory experiments have indicated that concentrations can...
Data on selected herbicides and two triazine metabolites in precipitation of the Midwestern and Northeastern United States, 1990-91
D. A. Goolsby, E.A. Scribner, E.M. Thurman, M.L. Pomes, M. T. Meyer
1995, Open-File Report 95-469
Weekly precipitation (rain and snow) samples were collected from 81 National Atmospheric Deposition Program/National Trends Network sites in the Midwestern and Northeastern United States for the analysis of herbicides. In addition, five high- elevation background sites along the Rocky Mountains and in Alaska were sampled to provide data on herbicides...
Water-resources activities of the U.S. Geological Survey in Illinois, 1994
G. O. Balding (compiler)
1995, Open-File Report 95-391
This report gives an overview of U.S. Geological Survey, Illinois District, Water Resources Division activities related to the water resources of the State of Illinois. The report includes sections describing District organization, programs, water conditions, data collection activities, and project summaries. Also included is a complete listing of District and...
Quality assurance/quality control manual; National Water Quality Laboratory
J.W. Pritt, J.W. Raese
1995, Open-File Report 95-443
Quality-control practices are established for the operation of the U.S. Geological Survey's National Water Quality Laboratory. These practices specify how samples are preserved, shipped, and analyzed in the Laboratory. This manual documents the practices that are currently (1995) used in the Laboratory....
