Preliminary report on the geology and geophysics of drill hole UE25a-1, Yucca Mountain, Nevada Test Site
Richard W. Spengler, D. C. Muller, R.B. Livermore
1979, Open-File Report 79-1244
A subsurface geologic study in connection with the Nevada Nuclear Waste Storage Investigations has furnished detailed stratigraphic and structural information about tuffs underlying northeastern Yucca Mountain on the Nevada Test Site. Drill hole UE25a-1 penetrated thick sequences of nonwelded to densely welded ash-flow and bedded tuffs of Tertiary age. Stratigraphic...
Chemical and biological quality of selected lakes in Ohio, 1976 and 1977
Robert L. Tobin, John D. Youger
1979, Water-Resources Investigations Report 78-109
Twenty-eight Ohio lakes (14 per year) were sampled by the U.S. Geological Survey and Ohio Environmental Protection Agency for the water-quality characteristics during the spring and summer of 1976 and 1977. Data items included: profiles of temperature, dissolved oxygen, pH, and specific conductance; physical, biological, nutrient, and organic characteristics; major...
A supplement to "Methods for collection and analysis of aquatic biological and microbiological samples"
Phillip E. Greeson, editor(s)
1979, Techniques of Water-Resources Investigations 05-A4
The report contains methods used by the U.S. Geological Survey to collect, preserve, and analyze waters to determine their biological and microbiological properties. It supplements, "Methods for Collection and Analysis of Aquatic Biological and Microbiological Samples" (TWRI, Book 5, Chapter A4, 1977, edited by P. E. Greeson, T. A. Ehlke,...
Possible uranium mineralization, Mineral Mountains, Utah
W. Roger Miller, John B. McHugh, Walter H. Ficklin
1979, Open-File Report 79-1354
The Mineral Mountains block in west-central Utah is a horst whose core stands structurally high relative to all nearby basin-and-range fault blocks. Rocks of the Mineral Mountains range from Precambrian to Quaternary in age, but mostly consist of Tertiary granitic rocks. The range lies with the Wah Wah-Tusher mineral belt....
Magnitude and frequency of floods in western Oregon
David Dell Harris, Larry L. Hubbard, Lawrence E. Hubbard
1979, Open-File Report 79-553
A method for estimating the magnitude and frequency of floods is presented for unregulated streams in western Oregon. Equations relating flood magnitude to basin characteristics were developed for exceedance probabilities of 0.5 to 0.01 (2- to 100-year recurrence intervals). Separate equations are presented for four regions: Coast, Willamette, Rogue-Umpqua, and...
Enhancement of Landsat images for lineament analysis in the area of the Salina Basin, New York and Pennsylvania
M. Dennis Krohn
1979, Open-File Report 79-533
Digital image processing of Landsat images of New York and Pennsylvania was undertaken to provide optimum images for lineament analysis in the area of the Salina Basin. Preliminary examination of Landsat images from photographic prints indicated sufficient differences between the spectral bands of the Landsat Multispectral Scanner (MSS) to warrant...
Availability of supplemental water supplies at salmonid fish-propagation stations in Wisconsin
C. Albert Harr, R.P. Novitzki
1979, Open-File Report 79-1170
Supplemental water supplies are available at all the 12 fish-propagation stations. At seven of the stations water may be obtained by diverting or impounding streams. Ground water is available from glacial sand-and-gravel aquifers at all the stations and from sandstone aquifers at 7 of the 12 stations. Probable well yields...
Surface-water features in Osceola County and adjacent areas, Florida
G.H. Hughes, James M. Frazee Jr.
1979, Open-File Report 79-1289
The western two-thirds of Osceola County, Fla., drains southward by way of the Kissimmee River and its tributaries; the eastern one-third drains eastward to the St. Johns River or to marshy areas that make up part of the headwaters of the St. Johns River. About 15 percent of the county...
Hydrologic data for Mountain Creek, Trinity River basin, Texas, 1977
F.L. Stroman
1979, Open-File Report 79-509
The collection of hydrologic data by the U.S. Geological Survey in the Mountain Creek watershed began on March 9, 1925, with the establishment of a stream-gaging station located about 2.5 miles upstream from the present site of Mountain Creek Lake Dam. The stream-gaging station was discontinued on July 5, 1933....
Urban stormwater data management system with applications to south Florida studies
Robert A. Miller, W. Harry Doyle Jr., Larry D. Wilson
1979, Water-Resources Investigations Report 79-93
A data management system was developed to store and retrieve urban stormwater data collected from four small urban basins in south Florida. The system is event oriented in that all data from one storm are stored together on the computer file. The data include descriptive information about the storm and...
Pesticide residues in agricultural drains, southeastern desert area, California
Lawrence A. Eccles
1979, Water-Resources Investigations Report 79-16
A study is being made to determine the occurrence and distribution of pesticides in the agricultural drains for approximately 3/4 million irrigated acres in the southeastern desert area of California. This report describes the results of the first year of sampling and analyzing (1) water in the drains , (2)...
Chemical analyses of coal and coal-associated rock samples from the Coalmont Formation, McCallum and Coalmont areas, North Park, Jackson County, Colorado
Joseph R. Hatch, Dawn Madden, Ronald H. Affolter
1979, Open-File Report 79-1099
As part of a continuing program by the U.S. Geological Survey to collect and chemically analyze representative samples of U.S. coals, 44 coal and coal-associated rock samples were collected from the Paleocene and Eocene, Coalmont Formation in the McCallum and Coalmont areas, North Park, Jackson County, Colorado. Twenty-eight samples (24...
