Water quality of a stream-aquifer system, southern Franklin County, Ohio
J.T. De Roche, A. C. Razem
1984, Water-Resources Investigations Report 84-4238
The chemical quality of the water resources in the Scioto River valley south of Columbus, Ohio, was evaluated on the basis of data collected from 74 wells and 4 surface-water sites. A very hard calcium bicarbonate water that is high in dissolved solids is characteristic of the aquifer. Mean pH...
Habitat Suitability Index Models: Lake trout (exclusive of the Great Lakes)
Michael D. Marcus, Wayne A. Hubert, Stanley H. Anderson
1984, FWS/OBS 82/10.84
The lake trout is an important commercial and sport fish in North America. In the Central Rocky Mountain regi on, 1ake trout are common ly referred to as "mackinaw". There is good evidence that lake trout should be called "1 ake charr" (Morton 1980). No subspecies of lake trout is...
Cost-effectiveness of the US Geological Survey stream-gaging program in Arkansas
M.E. Darling, T.E. Lamb
1984, Water-Resources Investigations Report 84-4084
This report documents the results of the cost-effectiveness of the stream-gaging program in Arkansas. Data uses and funding sources were identified for the daily-discharge stations. All daily-discharge stations were found to be in one or more data use categories, and none were candidates for alternate methods which would result in...
Maximum known stages and discharges of New York streams through September 1983
J.A. Robideau, P. M. Burke, Richard Lumia
1984, Open-File Report 83-927
This report lists the maximum known stages and discharges of New York streams through September 1981. The data represent 1,189 sites. Most data were obtained from files of the U.S. Geological Survey, but some were provided by other Federal, State, and private organizations. The information is grouped by major drainage...
A modification of the finite-difference model for simulation of two dimensional ground-water flow to include surface-ground water relationships
M.M. Ozbilgin, D.C. Dickerman
1984, Water-Resources Investigations Report 83-4251
The two-dimensional finite-difference model for simulation of groundwater flow was modified to enable simulation of surface-water/groundwater interactions during periods of low streamflow. Changes were made to the program code in order to calculate surface-water heads for, and flow either to or from, contiguous surface-water bodies; and to allow for more...
Water use in Arkansas, 1981
A.P. Hall, T.W. Holland
1984, Water-Resources Investigations Report 84-4070
Water use and consumption data for 1981 are presented by county and source. Use-data are presented by category for each county. Total water use, excluding wildlife impoundments, was 32,970 million gallons per day, which was 19 percent less than in 1980; consumption was 4,610 million gallons per day. Ground water...
Chemical quality of water at 14 sites near Kesterson National Wildlife Refuge, Fresno and Merced Counties, California
J. A. Izbicki
1984, Open-File Report 84-582
Data were collected to determine concentrations of major ions, nutrients, and selected trace elements in collector drains tributary to the San Luis Drain; the San Luis Drain near Kesterson Reservoir; Kesterson Reservoir; and selected drains, canals, and sloughs near but not tributary to Kesterson Reservoir, California. Results from 14 samples...
Relationship of suspended sediment to streamflow in the Green River Basin, Wyoming
B. H. Ringen
1984, Water-Resources Investigations Report 84-4026
The relation of suspended-sediment concentration to water discharge was computed using regression analysis for 33 stations and 2 miscellaneous sites in the Green River basin, Wyoming. These relations show that suspended-sediment concentrations vary in direct proportion to streamflow. The number of coincident instantaneous suspended-sediment concentration and water-discharge values available for...
Ground-water resources of the Mattapoisett River Valley, Plymouth County, Massachusetts
J.C. Olimpio, Virginia De Lima
1984, Water-Resources Investigations Report 84-4043
Ground-water withdrawals by municipal wells in the Mettapoisett River valley, Massachusetts, are expected to triple in the next two decades. State and local concern about the long-term impacts of these withdrawals on ground-water levels and streamflow made it necessary to assess the ground-water resources of the valley and to develop...
Appraisal of data for ground-water quality in Nebraska
R. A. Engberg
1984, Water Supply Paper 2245
This report summarizes existing data for groundwater quality in Nebraska and indicates their adequacy as a data base. Analyses have been made of water from nearly 10,000 wells by 8 agencies. Those analyses that meet reliability criteria have been aggregated by geologic source of water into four principal aquifer groupings--Holocene-Pleistocene...
