Maps to estimate average streamflow and headwater limits for streams in U.S. Army Corps of Engineers, Mobile District, Alabama and adjacent states
George H. Nelson Jr.
1984, Water-Resources Investigations Report 84-4274
U.S. Army Corps of Engineers permits are required for discharges of dredged or fill-material downstream from the ' headwaters ' of specified streams. The term ' headwaters ' is defined as the point of a freshwater (non-tidal) stream above which the average flow is less than 5 cu ft/s. Maps...
Water use in Ohio, 1980
Michael Eberle, J.A. McClure
1984, Water-Resources Investigations Report 84-4024
An estimated 13,389 million gallons of water per day were used in Ohio in 1980, in four major categories of water use. Of this total, 12,645 Mgal/d (million gallons per day) were taken from surface-water sources whereas 744 Mgal/d was ground water. Totals for each category (in Mgal/d) were: thermoelectric...
Water-quality characteristics of urban runoff and estimates of annual loads in the Tampa Bay area, Florida, 1975-80
M. A. Lopez, R.F. Giovannelli
1984, Water-Resources Investigations Report 83-4181
Rainfall, runoff, and water quality data were collected at nine urban watersheds in the Tampa Bay area from 1975 to 1980. Watershed drainage area ranged from 0.34 to 0.45 sq mi. Land use was mixed. Development ranged from a mostly residential watershed with a 19% impervious surface, to a commercial-residential...
Distribution and source of barium in ground water at Cattaraugus Indian Reservation, southwestern New York
R. B. Moore, W. W. Staubitz
1984, Water-Resources Investigations Report 84-4129
High concentrations of dissolved barium have been found in ground water from bedrock wells on the Seneca Nation of Indians Reservation on Cattaraugus Creek in southwestern New York. Concentrations in 1982 were as high as 23.0 milligrams per liter , the highest found reported from any natural ground-water system in...
Geohydrology of rocks penetrated by test well UE-25p#1, Yucca Mountain area, Nye County, Nevada
R. W. Craig, J. H. Robison
1984, Water-Resources Investigations Report 84-4248
Test well UE-25pNo1 was drilled in cooperation with the U.S. Department of Energy in the southwestern part of the Nevada Test Site, for investigations related to the isolation of high-level nuclear wastes. Rocks penetrated in the well are predominantly ash-flow tuffs of Tertiary age to a depth of 1,244 meters...
Quality of water from bedrock aquifers in the South Carolina Piedmont
G. G. Patterson, G.C. Padgett
1984, Water-Resources Investigations Report 84-4028
The geographic distributions of 12 common water-quality parameters of ground water from bedrock aquifers in the Piedmont physiographic province of South Carolina are presented in a series of maps. The maps are based on analyses by the South Carolina Department of Health and Environmental Control of water samples taken during...
Aldicarb-pesticide contamination of ground water in eastern Suffolk County, Long Island, New York
Julian Soren, W. G. Stelz
1984, Water-Resources Investigations Report 84-4251
Aldicarb, a toxic oxime-carbamate pesticide that was believed incapable of reaching ground water, was used in potato-farming areas of eastern Suffolk County, New York during 1975-80. In 1979, aldicarb was found in substantial concentrations in ground water throughout the area. The New York State Department of Health set a limit...
Runoff and water-quality characteristics of surface-mined lands in Illinois
Timothy P. Brabets
1984, Water-Resources Investigations Report 83-4265
Seven watersheds--three in western Illinois (Fulton County), two in south-western Illinois (St. Clair County), and two in southern Illinois (Williamson County)--were selected to assess the effect of surface mining on the quality and quantity of surface runoff. Each area had one site draining an unmined basin and a nearby site(s)...
Techniques for estimating flood hydrographs for ungaged urban watersheds
V.A. Stricker, V.B. Sauer
1984, Open-File Report 82-365
The Clark Method, modified slightly was used to develop a synthetic, dimensionless hydrograph which can be used to estimate flood hydrographs for ungaged urban watersheds. Application of the technique results in a typical (average) flood hydrograph for a given peak discharge. Input necessary to apply the technique is an estimate...
Water levels and water-level changes in the Prairie du Chien-Jordan and Mount Simon-Hinckley aquifers, Twin Cities metropolitan area, Minnesota, 1971-80
Michael Schoenberg
1984, Water-Resources Investigations Report 83-4237
The ground-water system in the Twin Cities Metropolitan Area includes five aquifers; two of these aquifers the Prairie du Chien-Jordan and the Mount Simon-Hinckley supply about 80 percent and 10 percent, respectively, of the ground water pumped for public supply. Water levels and changes in water levels in these two...
