Water-supply assessment of the Laramie-Fox Hills aquifer in parts of Adams, Boulder, Jefferson, and Weld Counties, Colorado
Paul A. Schneider
1980, Open-File Report 80-327
Groundwater in the Laramie-Fox Hills aquifer is a potential source of supplemental municipal water supplies for the communities of Erie, Lafayette, Louisville, and Superior in Colorado. The present water supplies for these communities are not always adequate to meet current demands. The U.S. Geological Survey made a water-supply assessment of...

Ground-water appraisal in northwestern Big Stone County, west-central Minnesota
W.G. Soukup
1980, Open-File Report 80-568
The development of ground water for irrigation in northwestern Big Stone County has not kept up with development in other irrigable areas of the State. This is due, in part, to the absence of extensive surficial aquifers and the difficulty in locating buried aquifers. Test augering south of Beardsley outlined a...
Evaluation of remote hydrologic data-acquisition systems, west-central Florida
J.F. Turner Jr., W. M. Woodham
1980, Water-Resources Investigations Report 79-102
The study provides an evaluation of the hydrologic applications of a land-line and two satellite data-relay systems operated during 1977-78 in the Southwest Florida Water Management District. These systems were tested to evaluate operational and reliability characteristics. Telephone lines were used to relay data in the land-line system, and the...

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...

Composition and properties of the Pierre Shale and equivalent rocks, northern Great Plains region
Leonard Gene Schultz, H. A. Tourtelot, J. R. Gill, J.G. Boerngen
1980, Professional Paper 1064-B
The Pierre Shale and equivalent rocks of Late Cretaceous age consist in the east-central Dakotas of several hundred feet of offshore-marine shale and minor marl; in west-central Montana near the sediment source the equivalents of the Pierre Shale consist of several thousand feet of volcanic-rich and mostly nonmarine sediments; and...

Study plan for the regional aquifer-system analysis of alluvial basins in south-central Arizona and adjacent states
T. W. Anderson
1980, Open-File Report 80-1197
The alluvial basins in the Southwestern United States constitute a major source of ground water and are relied upon extensively for agricultural, industrial, and public water supplies. Large-scale depletion of ground water is directly related to pumping that has occurred in the past few decades and is continuing today. The...
Mount St. Helens volcanic-ash fall in the Bull Run watershed, Oregon, March-June 1980
M.V. Shulters, Daphne G. Clifton
1980, Circular 850-A
During several periods of volcanic-ash eruption at Mount St. Helens, Wash., (March 30, May 25-26, May 30-June 2, and June 12-13, 1980) strong winds from the north occurred at high altitudes. As a result, the volcanic ash fell some 50 miles to the south in the Bull Run watershed, the...

Type curves for selected problems of flow to wells in confined aquifers
J.E. Reed
1980, Techniques of Water-Resources Investigations 03-B3
This report presents type curves and related material for 11 conditions of flow to wells m confined aquifers. These solutions, compiled from hydrologic literature, span an interval of time from Theis (1935) to Papadopulos, Bredehoeft, and Cooper (1973). Solutions are presented for constant discharge, constant drawdown, and variable discharge for pumping wells that fully penetrate leaky...
The accuracy of selected land use and land cover maps at scales of 1:250,000 and 1:100,000
Katherine Fitzpatrick-Lins
1980, Circular 829
Land use and land cover maps produced by the U.S. Geological Survey are found to meet or exceed the established standard of accuracy. When analyzed using a point sampling technique and binomial probability theory, several maps, illustrative of those produced for different parts of the country, were found to meet...

Appraisal of ground-water resources in the San Antonio Creek Valley, Santa Barbara County, California
C. B. Hutchinson
1980, Open-File Report 80-750
A nearly threefold increase in demand for water in the 154-square-mile San Antonio Creek valley in California during the period 1958-77 has increased the potential for overdraft on the ground-water basin. The hydrologic budget for this period showed a perennial yield of about 9,800 acre-feet per year and an annual...
