Quality-assurance data for routine water analysis in the laboratories of the US Geological Survey for water-year 1983
D.B. Peart, Nancy Thomas
1984, Water-Resources Investigations Report 84-4234
The U.S. Geological Survey maintains a quality-assurance program based on the analysis of reference samples for its two water-analysis laboratories located in Atlanta, Georgia, and Denver, Colorado. Reference samples containing selected inorganic constituents are prepared at the U.S. Geological Survey 's Ocala, Florida office and disguised as routine samples ,...
Time of travel and dispersion of solutes in a 36.4-mile reach of the North Platte River downstream from Casper, Wyoming
G.W. Armentrout Jr., L. R. Larson
1984, Water-Resources Investigations Report 82-4103
Time-of-travel and dispersion measurements made during a dye study November 7-8, 1978, are presented for a reach of the North Platte River from Casper, Wyo., to a bridge 2 miles downstream from below the Dave Johnston Power Plant. Rhodamine WT dye was injected into the river at Casper, and the...
Generalized skew coefficient for flood frequency computations for the State of Hawaii
Reuben Lee
1984, Water-Resources Investigations Report 84-4027
In 1976, the Hydrology Committee of the U.S. Water Resources Council estimated a generalized skew coefficient for flood frequency computations of -0.05 for the State of Hawaii. This value is the average of 30 stream gaging stations with 25 or more years of record through water year 1973. This report...
Hydrology and land use in Van Buren County, Michigan
T. R. Cummings, F. R. Twenter, D. J. Holtschlag
1984, Water-Resources Investigations Report 84-4112
This report gives the results of an investigation to determine the chemical and physical characteristics of ground and surface water in Van Buren County and to relate these characteristics to the agricultural use of land. Chemical inputs to the hydrologic system, including those from precipitation, animal wastes, septic tanks, and...
Map of the Carpinteria area and vicinity, Santa Barbara County, California, showing water-level contours for March 1983 and net change in water level between March 1982 and March 1983
W. R. Moyle Jr.
1984, Water-Resources Investigations Report 84-4067
A water-level contour map of the Carpinteria area, California, was constructed using 34 water-level measurements made by the Carpinteria County Water District in March 1983. Also shown on the map are five hydrographs that show water-level fluctuations in each well between 1978 and 1983. In addition, a water-level net-change map...
Percentage change in saturated thickness of the High Plains Aquifer, west-central Kansas, 1950 to average 1982-84
Marilyn E. Pabst, Barbara J. Dague
1984, Water-Resources Investigations Report 84-4357
Continuing studies are being made in west-central Kansas to provide up-to-date information to aid in the management of ground water for irrigation.  This report, prepared in cooperation with the Western Kansas Groundwater Management District No. 1, presents the fourth in a series of studies that uses a statistical technique, called...
Application of the U.S. Geological Survey's precipitation-runoff modeling system to the Prairie Dog Creek basin, southeastern Montana
L. E. Cary
1984, Water-Resources Investigations Report 84-4178
The U.S. Geological Survey 's precipitation-runoff modeling system was tested using 2 year 's data for the daily mode and 17 storms for the storm mode from a basin in southeastern Montana. Two hydrologic response unit delineations were studied. The more complex delineation did not provide superior results. In this...
Stratigraphy and structure of the western Kentucky fluorspar district
R. D. Trace, D.H. Amos
1984, Professional Paper 1151-D
The western Kentucky fluorspar district is part of the larger Illinois-Kentucky fluorspar district, the largest producer of fluorspar in the United States. This report is based largely on data gathered from 1960 to 1974 during the U.S. Geological Survey-Kentucky Geological Survey cooperative geologic mapping program of Kentucky. It deals chiefly...
Geohydrologic and drill-hole data for test well USW H-3, Yucca Mountain, Nye County, Nevada
William Thordarson, F. E. Rush, R.W. Spengler, S. J. Waddell
1984, Open-File Report 84-149
Test well USW H-3 is one of a series of test wells drilled in and near the southwestern part of the Nevada Test Site for hydraulic testing, hydrologic monitoring, and geophysical logging. The work was performed in cooperation with the U.S. Department of Energy as part of the Nevada Nuclear...
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...
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)...
