Water-quality conditions and an evaluation of ground- and surface-water sampling programs in the Livermore-Amador Valley, California
S. K. Sorenson, P. V. Cascos, R. L. Glass
1985, Water-Resources Investigations Report 84-4352
A program to monitor the ground- and surface water quality in the Livermore-Amador Valley has been operated since 1976. As of 1982, this monitoring network consisted of approximately 130 wells, about 100 of which were constructed specifically for this program, and 9 surface water stations. Increased demand on the groundwater...
Phase I summary and phase II plan for comparing regulated with unregulated streamflow in the Yakima River at Union Gap, Washington
C.H. Swift
1985, Water-Resources Investigations Report 83-4015
A preliminary investigation of the effects of reservoir storage and canal diversion on the flow of the Yakima River at Union Gap , Washington indicates that those effects are measurable and substantial--on the average causing a reduction of roughly one-quarter from the unregulated flow. Preliminary computations of the unregulated flow...
Reported withdrawals and estimated use of water in Oklahoma during 1982
J.D. Stoner
1985, Water-Resources Investigations Report 85-4084
Reported water withdrawals in Oklahoma during 1982 were 1,270.64 million gallons per day. The withdrawals were about equally distributed between ground water and surface water with 46 percent being ground water and 54 percent being surface water. In general, the western counties rely on ground water and the eastern counties...
Chemical and biological quality of selected lakes in Ohio, 1978 and 1979
C.G. Angelo, John D. Youger
1985, Open-File Report 84-249
Twenty-eight Ohio lakes were sampled by the U.S. Geological Survey and the Ohio Environmental Protection Agency for water-quality characteristics during the spring and summer of 1978 and 1979. This report is the third in a series covering a lake-sampling program that began in 1975. Data include water-column profiles of temperature,...
Chemical and physical characteristics of water and sediment in Scofield Reservoir, Carbon County, Utah
Kidd M. Waddell, D.W. Darby, S.M. Theobald
1985, Water Supply Paper 2247
Evaluations based on the nutrient content of the inflow, outflow, water in storage, and the dissolved-oxygen depletion during the summer indicate that the trophic state of Scofield Reservoir is borderline between mesotrophic and eutrophic and may become highly eutrophic unless corrective measures are taken to limit nutrient inflow.Sediment deposition in...
Pesticides in the nation's rivers, 1975-1980, and implications for future monitoring
Robert J. Gilliom, Richard B. Alexander, Richard A. Smith
1985, Water Supply Paper 2271
Water samples were taken four times per year and bed-sediment samples two times per year during 1975-80 at 160 to 180 stations on major rivers of the United States. Samples were analyzed for 18 insecticides and 4 herbicides, which together accounted for about one-third of the total amount of all...
Effects of low-level dams on the distribution of sediment, trace metals, and organic substances in the lower Schuylkill River basin, Pennsylvania
Thomas H. Yorke, John K. Stamer, Gary L. Pederson
1985, Water Supply Paper 2256-B
Heavy use of the Schuylkill River for municipal water supplies and a history of accidental spills and discharges of trace metals and organic substances have been a concern of State and local officials for many years. The U.S. Geological Survey, as part of their River Quality Assessment Program, developed a...
Map showing abundance and distribution of arsenic in oxide residues of stream-sediment samples, Medford 1 degree by 2 degrees Quadrangle, Oregon-California
Charles L. Whittington, Reinhard W. Leinz, David J. Grimes
1985, Miscellaneous Field Studies Map 1383-J
Stream-sediment sampling in the Medford 1o x 2o quadrangle was undertaken to provide to aid in assessment of the mineral resource potential of the quadrangle. This map presents data on the abundance and distribution of copper in the oxide residues (oxalic-acid leachates) of stream sediments and in the minus-0.18-mm sieve fraction...
Maps showing abundance and distribution of mercury in rock samples, Medford 1 degree by 2 degrees Quadrangle, Oregon-California
Charles L. Whittington, David J. Grimes, Reinhard W. Leinz
1985, Miscellaneous Field Studies Map 1383-K
This map presents data on the abundance and distribution of mercury in 3,146 rock samples from the Medford quadrangle. Most of the rock samples were collected incidental to geologic, geochemical, and mineral resources studies in the period from 1974 to 1980, but about 6 percent date from earlier investigations (Wells,...
Map showing depth to bedrock in the Seattle 30' by 60' Quadrangle, Washington
J. C. Yount, G.R. Dembroff, G.M. Barats
1985, Miscellaneous Field Studies Map 1692
Maps depicting thicknesses of sedimentary units (isopach maps) are standard tools for interpretation of processes and patterns of sedimentation within basins (Potter and Pettijohn, 1977, p. 283-287). Isopach maps showing the thickness of unconsolidated sedimentary deposits overlying bedrock may help locate sources of aggregate and potential ground-water aquifers. These maps...
Ground-water contribution to the salinity of the Upper Colorado River Basin
J. W. Warner, F.J. Heimes, R.F. Middelburg
1985, Water-Resources Investigations Report 84-4198
A study was conducted to estimate the contribution of groundwater and other natural sources to the salinity of streamflow in the Upper Colorado River Basin. Salt-load estimates were derived from a mass balance using measurements of quantity and quality of base streamflow. Groundwater inflow was considered to represent the bulk...
Water resources data, Texas, water year 1984; Volume 2. San Jacinto River basin, Brazos River basin, San Bernard River basin, and intervening coastal basins
H.D. Buckner, E.R. Carrillo, H.J. Davidson
1985, Water Data Report TX-84-2
Surface-water data for the 1984 water year for Texas are presented in three volumes, appropriately identified as to content by river basins. Data in each volume consist of records of stage, discharge, and water quality of streams and canals; and stage, contents, and water quality of lakes and reservoirs. Also...
Hydraulic and sediment characteristics at the North Channel Bridge, Jamaica Bay, New York
W. W. Staubitz, S.W. Wolcott
1985, Water-Resources Investigations Report 85-4085
Data were collected during the spring of 1984 in the vicinity of North Channel Bridge in Jamaica Bay, New York to define the hydraulic regime and the physical characteristics and chemical quality of bottom sediments. The data were used in a semiquantitative analysis to predict the effects of bridge replacement...
