Water resources data for California, water year 1976; Volume 2: Pacific Slope basins from Arroyo Grande to Oregon State line except Central Valley
California District of the Water Resources Division
1977, Water Data Report CA-76-2
Water-resources data for the 1976 water year for California consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; records of water levels in selected observation wells; and selected chemical analyses of ground water. Records for a few pertinent streamflow...
The Triassic Chitistone Limestone, Wrangell Mountains, Alaska: stressing detailed descriptions of sabkha facies and other rocks in lower parts of the Chitistone and their relations to Kennecott-type copper deposits
Augustus K. Armstrong, E. M. MacKevett
1977, Open-File Report 77-217
Recent investigations show that sabkha deposits were important in the genesis of Kennecott-type copper ore. Massive chalcocite-rich lodes at Kennecott and nearby deposits formed in the lower 110 meters of the Upper Triassic Chitistone Limestone. The Chitistone and superimposed Upper Triassic and Jurassic sedimentary rocks formed in a marine basin...
Ground-water supplies in the Murfreesboro area, Tennessee
Donald Robert Rima, Mary S. Moran, E. Jean Woods
1977, Water-Resources Investigations Report 77-86
Ground water occurs in the Murfreesboro area in solution openings in the otherwise dense paleozoic limestones that underlie most of central Tennessee. Test drilling based on conceptual models of ground-water occurrence in carbonate-rock aquifers indicate that multimillion-gallon-per-day supplies could be developed from strategically located production wells in the Shiloh and...
A digital model of the Floridan Aquifer, north of Tampa, Florida
A.F. Robertson, M. J. Mallory
1977, Water-Resources Investigations Report 77-64
A regional ground-water model of the Floridan aquifer was constructed for an 875-square-mile portion of the rapidly developing area north of Tampa Bay. The digital model was calibrated by comparing observed (March 1974 and May 1975) and computed potentiometric heads. A good comparison was obtained by adjusting leakance and transmissivity....
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Eagle Quadrangle, Alaska
Edward Huntington Cobb
1977, Open-File Report 77-845
These summaries of references are designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral occurrences in the Eagle quadrangle, Alaska. All references to reports of the Geological Survey, to most reports of the U.S. Bureau of Mines, and to most reports...
Subsurface-temperature data for some wells in western Utah
F. Eugene Rush
1977, Open-File Report 77-132
The data contained in this report were gathered as part of a hydrothermal reconnaissance of the State of Utah. These data, plus additional data and information, will form the basis for a future interpretive report. These data are being released separately from and prior to the interpretive report, to make...
Digital model analysis of the principal artesian aquifer, Savannah, Georgia area
H. B. Counts, R.E. Krause
1977, Water-Resources Investigations Report 76-133
A digital model of the principal artesian aquifer has been developed for the Savannah, Georgia, area. The model simulates the response of the aquifer system to various hydrologic stresses. Model results of the water levels and water-level changes are shown on maps. Computations may be extended in time, indicating changes...
Quality of rivers of the United States, 1974 water year: based on the National Stream Quality Accounting Network (NASQAN)
Richard O. Hawkinson, John F. Ficke, L.G. Saindon
1977, Open-File Report 77-151
The National Stream Quality Accounting Network (NASQAN) was established by the U.S Geological Survey to determine and compare the quality at key locations on the Nation 's major rivers. There are 345 stations in the network--data from the first 101 of these (those operating during the 1974 water year) are...
Magnitude and frequency of floods in California
Arvi O. Waananen, John R. Crippen
1977, Water-Resources Investigations Report 77-21
The magnitude and frequency of floods from gaged and ungaged drainage areas in California, for any recurrence interval from 2 to 100 years, can be estimated by use of the method presented. Equations relating flood magnitudes of selected frequency to basin characteristics such as drainage area, precipitation, and altitude were...
