1982, Open-File Report 81-499
Pumpage data from about 2,100 wells used for public and nonpublic water-supply in Nassau County from 1920-77 have been collected and are available for public inspection at the U.S. Geological Survey office in Syosset, Nassau County. Except for wells in use before 1920, these data constitute the entire record available...
Streamflow losses to Madison Group rocks in the Little Belt and Big Snowy Mountains, Montana
R.D. Feltis, Ronald R. Shields
1982, Water-Resources Investigations Report 82-49
Four streams originating in the Little Belt and Big Snowy Mountains in central Montana were measured in 1975 to determine streamflow losses across outcrops of the Madison Group (Mississippian age). Based on streamflow data obtained for 39 months at two streamflow-gaging stations on the Middle Fork Judith River, the average...

Chemical composition of bulk precipitation in the North-Central and Northeastern United States, December 1980 through February 1981
Norman E. Peters, Joseph E. Bonelli
1982, Circular 874
Samples of bulk precipitation were collected at 179 sites in the North-Central and Northeastern United States for 3 months during winter 1980-81 to provide data on the distribution of chemical constituents. Concentrations and average daily loads of 29 dissolved constituents were determined. Sodium and chloride deposition was relatively high in...
Estimates of vertical hydraulic conductivity and regional ground-water flow rates in rocks of Jurassic and Cretaceous age, San Juan Basin, New Mexico and Colorado
P. F. Frenzel, F. P. Lyford
1982, Water-Resources Investigations Report 82-4015
The San Juan structural basin northwestern New Mexico was modeled in three dimensions using a finite-difference, steady-state model. The modeled space was divided into seven layers of square prisms that were 6 miles on a side in the horizontal directions. In the vertical direction, the layers of prisms ranged in...

Water use in Wisconsin, 1979
C.L. Lawrence, B.R. Ellefson
1982, Water-Resources Investigations Report 82-444
This report summarizes the uses of water in Wisconsin for 1979, except aesthetics, navigation, and recreational use. The greatest single use of water, an instream use, was for hydroelectric power production. About 26 trillion gallons, or 93 percent, was used for this purpose. Of the other 7 percent where water is...
Effects of volcanic ash on the benthic environment of a mountain stream, northern Idaho
S.A. Frenzel
1982, Water-Resources Investigations Report 82-4106
The May 18, 1980, eruption of Mount St. Helens deposited about 15 millimeters of volcanic ash on the Big Creek basin in northern Idaho. Much of the uncompacted ash remained on hillsides a year after the eruption. Physical and chemical analyses of water samples from Big Creek collected from December...
