Streamflow statistical summaries for Colorado streams through September 30, 1975; Volume 3, Colorado River basin from Gunnison River to San Juan River
Harold E. Petsch Jr.
1979, Open-File Report 83-693
This report contains statistical summaries of daily streamflow data as of September 30, 1975, for 234 stations west of the Continental Divide in Colorado and adjacent States for use by agencies and individuals engaged in water studies. To be included in this report, a station had to have a minimum...
Maps showing ground-water conditions in the New Driver-Cave Creek area, Maricopa and Yavapai counties, Arizona; 1977
G. R. Littin
1979, Water-Resources Investigations Report 79-1068
The New River-Cave Creek area includes about 500 square miles in central Arizona. The ground-water conditions vary greatly owing to large differences in rock type and extent of fracturing. Information shown on the maps includes depth to water, altitude of the water level, well depth, and specific conductance and fluoride...
Geologic interpretation of aeromagnetic map of the Seward and Blying Sound quadrangles, Alaska
J. E. Case, R. G. Tysdal, John W. Hillhouse, C. S. Grommé
1979, Miscellaneous Field Studies Map 880-D
An aeromagnetic survey of the Seward and northern part of the Blying Sound quadrangles was flown by Geometrics, Inc., during 1975-77 to provide magnetic data to aid in an appraisal of the mineral resources. Background details of the regional geology and major structures are described in a companion report by...
Chemical quality of ground water on Cape Cod, Massachusetts
M. H. Frimpter, F. B. Gay
1979, Water-Resources Investigations Report 79-65
Cape Cod is a 440 square mile hook-shaped peninsula which extends 40 miles into the Atlantic. Freshwater in Pleistocene sand and gravel deposits is the source of supply for nearly 100 municipal and thousands of private domestic wells. Most ground water on Cape Cod is of good chemical quality for...
Effects of landfill leaching on water quality and biology of a nearby stream, South Cairo, Greene County, New York
Theodore A. Ehlke
1979, Water-Resources Investigations Report 79-13
A 1-kilometer stream reach receiving leachate-enriched water from a small municipal landfill in Greene County, N.Y., was studied from 1971-75 to document streamflow rates and chemical quality of the stream and ground water. The distribution of benthic invertebrates and microorganisms in the stream above the landfill was markedly different from...
Chemical, physical, and radiological quality of selected public water supplies in Florida, November 1977-February 1978
G. A. Irwin, Robert W. Hull
1979, Water-Resources Investigations Report 79-50
Virtually all treated public water supplies sampled in Florida meet the National Interim Primary and Proposed Secondary Drinking Water Regulations. These findings are based on a water-quality reconnaissance of 129 treated public supplies throughout the State during the period November 1977 through February 1978. While primary drinking water regulation exceedences...
The Oligocene aquifer system in Mississippi
L. A. Gandl
1979, Water-Resources Investigations Report 79-28
The Oligocene aquifer system in Mississippi consists of limestone and marl members of the Vicksburg Group, and the underlying Forest Hill Sand. The aquifer system crops out in a band 5 to 10 miles wide, that trends southeast across the State from the Warren-Yazoo County line to northeastern Wayne County....
Probable hydrologic effects of a hypothetical failure of Mackay Dam on the Big Lost River Valley from Mackay, Idaho to the Idaho National Engineering Laboratory
Leroy Druffel, Gloria J. Stiltner, Thomas N. Keefer
1979, Water-Resources Investigations Report 79-99
Mackay Dam is an irrigation reservoir on the Big Lost River, Idaho, approximately 7.2 kilometers northwest of Mackay, Idaho. Consequences of possible rupture of the dam have long concerned the residents of the river valley. The presence of reactors and of a management complex for nuclear wastes on the reservation...
Ground water in the San Juan Basin, New Mexico and Colorado
Forest P. Lyford
1979, Water-Resources Investigations Report 79-73
Principal aquifers in the San Juan Basin of New Mexico and Colorado are the Entrada Sandstone, Westwater Canyon Member of the Morrison Formation, Gallup Sandstone, several sandstones in the Mesaverde Group above the Gallup (Dalton Sandstone, Point Lookout Sandstone, Menefee Formation, Cliffhouse Sandstone), and sandstones of tertiary.Most ground water flows...
Revision of the documentation for a model for calculating effects of liquid waste disposal in deep saline aquifers
Inc. INTERA Environmental Consultants
1979, Water-Resources Investigations Report 79-96
The model developed under this contract is a modified version of the deep well disposal model developed by INTERCOMP Resource Development and Engineering, Inc., for the U.S. Geological Survey (A model for calculating effects of liquid waste disposal in deep saline aquifers). The model is a finite-difference numerical solution of...
Estimation of floods of various frequencies for the small ephemeral streams in eastern Washington
W.L. Haushild
1979, Water-Resources Investigations Report 79-81
Equations were developed to estimate the magnitude of floods for various occurrence frequencies at ungaged sites on ephemeral streams that drain small, relatively undeveloped basins in the semiarid part of eastern Washington. The equations were developed from regression analyses that used the logarithms of the longitude indexes of gaged sites,...
Geohydrology and digital-simulation model of the Farrington aquifer in the northern coastal plain of New Jersey
George M. Farlekas
1979, Water-Resources Investigations Report 79-106
A two-dimensional digital-computer flow model was developed to simulate the Farrington aquifer in the northern part of the Coastal Plain of New Jersey. The area of detailed study includes approximately 500 square miles in Middlesex and Monmouth Couties where the aquifer provides a large part of the municipal and industrial...
Water-table map of Waukesha County, Wisconsin
J. B. Gonthier
1979, Water-Resources Investigations Report 79-43
A map (scale 1:100,000) was prepared of the water table in Waukesha County in southeastern Wisconsin using water levels from more than 1,700 wells. The work was done as part of a cooperative project between the U.S. Geological Survey, the University of Wisconsin-Extension, Geological and Natural History Survey, and the...
Ground-water quality in the upper Santa Ana River basin, southern California
Lawrence A. Eccles
1979, Water-Resources Investigations Report 79-113
The principal ground-water quality problems in the Santa Ana River basin, as determined from two samplings (1968-69 and 1977-78), are high concentrations of dissolved solids in general and nitrate-nitrogen in particular. The distribution of dissolved solids exceeding 800 milligrams per liter was smaller in area in 1977-78 than in 1968-69....
Relation of sediment yield to climatic and physical characteristics in the Missouri River basin
P. R. Jordan
1979, Water-Resources Investigations Report 79-49
Data from 64 stream-sediment stations and reservoirs in the plains area and from 15 stream-sediment stations in the mountainous area were analyzed to determine the relation of sediment yield to basin characteristics. Data from each sediment station and reservoir represented at least 7 years of sediment discharge in the plains...
Water resources of shallow aquifers in the Upper Poplar River basin, northeastern Montana
R.D. Feltis
1979, Water-Resources Investigations Report 79-51
The aquifer system studied in the upper Popular River basin in Montana ranges in age from Late Cretaceous to Holocene. Most wells obtain water from the Paleocene Fort Union Formation or younger rocks. The potentiometric surface of the Fort Union and overlying rocks indicates movement of water from the high...
