Progress toward a ground-water-quality monitoring network for Idaho
R.L. Whitehead
1978, Open-File Report 78-786
A ground-water-quality monitoring network is being designed for Idaho. The primary objectives of the network are to (1) determine the present quality of the State's ground water, (2) provide continual monitoring of groundwater quality for water-management purposes, and (3) serve as a warning system of undesirable changes in ground-water quality. Data...
Sediment yields for selected streams in Texas
C.T. Welborn, R. Bryce Bezant
1978, Open-File Report 78-83
The U.S. Geological Survey began a study to determine sediment yields for selected streams in Texas during the 1966 water year to provide information for areas in which sediment-yield data were meager or lacking. These data will aid in delineating problem areas and planning for water-resources development in the State....
Water resources data for Iowa, water year 1977
Water Resources Division, U.S. Geological Survey
1978, Water Data Report IA-77-1
This report was prepared by personnel of the Iowa district of the Water Resources Division of the U.S. Geological Survey under the supervision of S. W. Wiitala, District Chief, and Alfred Clebsch, Jr., Regional Hydrologist, Central Region. It was done in cooperation with the State of Iowa and with other...

Jesse William Whitlow, Philip J. Geraci, Peter C. Mory, Elizabeth R. King
1978, Open-File Report 78-527
A mineral resource evaluation of the Rock River Canyon Wilderness Study Area, Alger County, Mich., was completed in 1975 by personnel of the U.S. Geological Survey and the U.S. Bureau of Mines. The area consists of approximately 22 km2 in the Hiawatha National Forest.Rocks exposed in the area include sandstone,...
Calibration of a simple oilspill trajectory model using the Argo Merchant spill
Timothy Wyant
1978, Open-File Report 78-334
An oil spill risk analysis was conducted to determine the relative envionmental hazards of developing oil in different regions of the Eastern Gulf of Mexico Outer Continental Shelf lease area. The study analyzed the probability of spill occurrence, likely paths of the spills, and locations in space and time of...
Least-squares refinement of powder diffraction data for unit cell parameters: Program listing for DEC 10 computer
George Van Trump, Phoebe L. Hauff
1978, Open-File Report 78-431
This FORTRAN computer program is a time-sharing version of the classic program of Appleman and Evans (1973) and Evans, Appleman, and Handwerker (1963), which indexes powder patterns and refines unit-cell dimensions. The program, originally written to be processed in batch mode for an IBM computer, was modified to run in...
Potentiometric surface of Floridan aquifer, Southwest Florida Water Management District and adjacent areas, September 1977
P.D. Ryder, L. R. Mills, C. P. Laughlin
1978, Water-Resources Investigations Report 78-9
A potentiometric-surface map of the Southwest Florida Water Management District depicts the annual high water-level period. Potentiometric levels increased 15 to 30 feet between May 1977 and September 1977 in the citrus and farming sections of southeastern Hillsborough, northern Hardee, and southwestern Polk Counties. These areas are widely affected by...
Update and revision of brachiopod collections of the Phosphoria, Park City, and Shedhorn Formations (Permian) of the U.S. Geological Survey
Bruce R. Wardlaw
1978, Open-File Report 78-692
The numerous collections amassed by the U.S. Geological Survey's study of the Western Phosphate Field have been examined. Many collections already have been discarded; and only those still housed at the Smithsonian are dealt with in this paper. Future studies of the biostratigraphy and paleogeography of the Phosphoria Formation and...
Contact-metasomatic magnetite deposit, Medfra Quadrangle, Alaska
M.L. Throckmorton, William Wallace Patton
1978, Open-File Report 78-26
A small contact-metasomatic magnetite deposit was discovered in the Medfra quadrangle, Alaska, in 1976. It occurs at the contact between a Cretaceous or early Tertiary quartz monzonite stock and Paleozoic limestone and dolomite. The ore is a magnetite-clinohumite-hematite rock that contains up to 60 volume percent magnetite and 76 weight...
