Low-flow characteristics of streams in the upper Wisconsin River basin, Wisconsin
Warren A. Gebert
1980, Open-File Report 80-691
Low-flow characteristics of streams in the upper Wisconsin River basin are presented. Included are estimates of low-flow frequency at 10 gaging stations, flow duration at 8 gaging stations, and low-flow frequency characteristics at 13 low-flow partial-record stations and 81 miscellaneous sites. Equations are provided to estimate low-flow characteristics at ungaged...
Summary of water-quality data for selected streams in Colorado
M.W. Gaydos
1980, Open-File Report 80-682
This report presents the first statewide summary of water-quality data for selected streams in Colorado. Included in the report are a tabulation of the 165 surface-water-sampling sites for which five or more analyses of major chemical constituents were available at the end of the 1978 water year and a tabulation...
Altitude of the water table in the alluvial and Wilcox aquifers in the vicinity of Richland and Tehuacana creeks and the Trinity River, Texas, December 1979
Sergio Garza
1980, Open-File Report 80-1007
This map shows the altitude of the water table in the alluvial and Wilcox aquifers in the vicinity of Richland and Tehuacana Creeks and the Trinity River, Tex., in December 1979. The water-table contours were constructed on the basis of water-level control derived from an inventory of shallow wells in...
Cost effective stream-gaging strategies for the Lower Colorado River basin; the Blythe field office operations
Marshall E. Moss, Edward J. Gilroy
1980, Open-File Report 80-1048
This report describes the theoretical developments and illustrates the applications of techniques that recently have been assembled to analyze the cost-effectiveness of federally funded stream-gaging activities in support of the Colorado River compact and subsequent adjudications. The cost effectiveness of 19 stream gages in terms of minimizing the sum of...
Results of water quality sampling near Richton, Cypress Creek and Lampton salt domes, Mississippi
L. A. Gandl, C. A. Spiers
1980, Open-File Report 80-443
In the Mississippi salt basin in southern Mississippi, chemical quality studies of surface water and ground water have been made to determine present water-quality conditions near three salt domes being studied by the Department of Energy as potential repositories for radioactive wastes. Chloride concentrations in excess of 60 milligrams per...
Probable high ground-water levels on Cape Cod, Massachusetts
Michael H. Frimpter
1980, Open-File Report 80-1008
Water-level records from 146 short-term (1 year) observation wells and 13 long-term (16-28 years) observation wells were used to estimate the probable high ground-water level that could occur at any site on Cape Cod. The estimation was based on correlation of a single water-level measurement from a test site with...
Determining the availability of sediment-bound trace metals to aquatic deposit-feeding animals
Samuel N. Luoma, D.J. Cain, E.A. Thomson, C. Johansson, E. A. Jenne, G.W. Bryan
1980, Open-File Report 80-341
Physicochemical form affects, by as much as 1000 fold, the uptake rate by deposit-feeding clams of metals bound to sediments. The strength of metal binding to the different sedimentary binding substrates controls this effect. Statistical studies that were spatially intensive (comparing 35 stations in 17 estuaries) and temporally intensive (2...
Distribution of trace elements in bottom sediment of the northern Bering Sea
Bradley R. Larsen, C. Hans Nelson, Chris Heropoulos, Jeffrey J. Patry
1980, Open-File Report 80-399-A
2-dimensional contour and 3-dimensional value-surface maps of semi-quantitative emission spectographic analyses for over 50 elements in surface sediment from 180 sampling stations are presented. For purposes of discussion, certain of these elements have been grouped into the following categories: petroleum indicators, heavy metals, potentially toxic elements, chemically sensitive elements, major...
Helicopter airborne electromagnetic survey (using the Dighem II system) of parts of the Lake City caldera, Hinsdale County, Colorado
D.C. Fraser, Z. Dvorak
1980, Open-File Report 80-917
The data presented herein is from an airborne electromagnetic-resistivity-survey conducted by Dighem Limited of Toronto Canada for the U.S. Geological Survey. The area surveyed is located in the western San Juan Mountains near Lake City, Colorado. The general area covered is between 37°45' and 38° latitude north and 107°15' and...
The surficial aquifer at the U.S. Naval Station near Mayport, Florida
Bernard J. Franks
1980, Open-File Report 80-765
The surficial aquifer at the U.S. Naval Station near Mayport, Florida, consists of about 70 feet of unconsolidated sand, shell , and clay. The principal water-bearing zone is a shell bed 35 to 55 feet below land surface. The aquifer is unconfined, and the water table was about 4 feet...
Drainage areas of selected surface-water sites in Florida
Donald W. Foose
1980, Open-File Report 80-957
Drainage areas for about 1,500 surface-water sites on streams and lakes in Florida are contained in this report. Sites are described in relation to a nearby city or town, and are located by county, by latitude-longitude, and by topographic map on which it is located. In addition, the surface areas...
