Subsurface geology and porosity distribution, Madison Limestone and underlying formations, Powder River basin, northeastern Wyoming and southeastern Montana and adjacent areas
James A. Peterson
1978, Open-File Report 78-783
To evaluate the Madison Limestone and associated rocks as potential sources for water supplies in the Powder River Basin and adjacent areas, an understanding of the geologic framework of these units, their lithologic facies patterns, the distribution of porosity zones, and the relation between porosity development and stratigraphic facies is...
The Coffee Sand and Ripley aquifers in Mississippi
E. H. Boswell
1978, Water-Resources Investigations Report 78-114
The Coffee Sand and Ripley aquifers, of Cretaceous age, are in the Selma Group in northern Mississippi. The aquifers contain freshwater in an area of about 4,400 square miles in northern Mississippi. Water produced from the aquifers by public water systems and numerous industries in 1975 averaged about 4 Mgal/d....
Stormwater-runoff data for a highway area, Broward County, Florida
Jack Hardee, Robert A. Miller, Harold C. Mattraw Jr.
1978, Open-File Report 78-612
Rainfall, stormwater discharge, and water-quality data for both rainfall and runoff are summarized for a highway area near Pompano Beach, Florida. Loads for 20 water-quality constituents were computed for the runoff from 41 storms between April 1975, and July 1977. The basin of 58.3 acres contains a 3,000 ft segment...
A progress report on estuary modeling by the finite-element method
William G. Gray
1978, Open-File Report 78-479
Various schemes are investigated for finite-element modeling of two-dimensional surface-water flows. The first schemes investigated combine finite-element spatial discretization with split-step time stepping schemes that have been found useful in finite-difference computations. Because of the large number of numerical integrations performed in space and the large sparse matrices solved, these...
Hydrogeologic data for the Bear Creek subsurface-injection test site, St. Petersburg, Florida
John J. Hickey
1978, Open-File Report 78-853
Lithologic, hydraulic, geophysical, and water-quality data were collected at the Bear Creek subsurface-injection test site at St. Petersburg, FL. The data were collected to determine the feasibility of subsurface injection of storm runoff. An exploratory hole and five observation wells were constructed between October 1974 and April 1976. The lithology...
Distribution of organic carbon and petroleum source rock potential of Cretaceous and lower Tertiary carbonates, south Florida basin: Preliminary results
James George Palacas
1978, Open-File Report 78-140
Analyses of 134 core samples from the South Florida Basin show that the carbonates of Comanchean age are relatively richer in average organic carbon (0.41 percent) than those of Coahuilan age (0.28 percent), Gulfian age (0.18 percent) and Paleocene age (0.20 percent). They are also nearly twice as rich as...
Ground-water availability in the Hayes-Red Willow, Frenchman, and Meeker-Driftwood irrigation districts, southwest Nebraska
E.G. Lappala, P.F. Hemphill, R.E. Booker
1978, Open-File Report 78-461
Surface-water supplies are diminishing in the Hitchcock-Red Willow and Frenchman Valley Irrigation Districts in southwest Nebraska. Stream depletions due to ground-water withdrawals upstream from Enders Reservoir (northwest of the study area) have resulted in a shortage of about 8,700 acre-feet per year. The availability of ground water to supply part...
Summary appraisals of the nation's ground-water resources – Missouri basin region
O. James Taylor
1978, Professional Paper 813-Q
The Missouri Basin Region lies in the north-central part of the United States and southern Canada. It includes parts of Alberta and Saskatchewan in Canada; parts of Montana, Wyoming, North Dakota, South Dakota, Minnesota, Iowa, Colorado, Kansas, and Missouri, and all of Nebraska in the United States. The region includes...
Summary appraisals of the nation's ground-water resources – Souris-Red-Rainy region
Harold O. Reeder
1978, Professional Paper 813-K
A broad-perspective analysis of the ground-water resources and present and possible future water development and management in the Souris-Red-Rainy Region is presented. The region includes the basins of the Souris River within Montana and North Dakota; the Red River of the North in South Dakota, North Dakota, and Minnesota; and...
Summary appraisals of the nation's ground-water resources – Mid-Atlantic region
Allen Sinnott, Elliot Morse Cushing
1978, Professional Paper 813-I
The Mid-Atlantic Region covers a total area of about 108,000 square miles. It includes parts of Vermont, Massachusetts, New York, Pennsylvania, Maryland, West Virginia, and Virginia, the entire States of New Jersey and Delaware, and the District of Columbia. It encompasses the entire drainage basins (within the United States) of...
Selected data from thermal-spring areas, southwestern Montana
Robert B. Leonard, Tordis M. Brosten, Norman A. Midtlyng
1978, Open-File Report 78-438
During 1975-77 the Montana district of the U.S. Geological Survey collected and assembled data describing the flow, temperature, and chemical characteristics of thermal and related waters. The work was part of an assessment of the geothermal resources of southwestern Montana, excluding Yellowstone Park. The purpose of this report is to...
