Regional evaluation of hydrologic factors and effects of pumping, St Peter-Jordan aquifer, Iowa
M. R. Burkart, Robert Buchmiller
1990, Water-Resources Investigations Report 90-4009
The St. Peter-Jordan aquifer includes the Cambrian Jordan Sandstone and the overlying Ordovician Prairie du Chien Group and St. Peter Sandstone. The aquifer is present throughout Iowa and is confined beneath other aquifers in much of the State. Information on the aquifer available from drillers and contractors, provided estimates of...
Hydrologic framework of Long Island, New York
Douglas A. Smolensky, Herbert T. Buxton, Peter K. Shernoff
1990, Hydrologic Atlas 709
Long Island, N.Y., is underlain by a mass of unconsolidated geologic deposits of clay, silt, sand, and gravel that overlie southward-sloping consolidated bedrock. These deposits are thinnest in northern Queens County (northwestern Long Island), where bedrock crops out, and increase to a maximum thickness of 2,000 ft in southeastern Long...
Evaluation of three electronic report processing systems for preparing hydrologic reports of the U.S Geological Survey, Water Resources Division
G.J. Stiltner
1990, Open-File Report 89-576
In 1987, the Water Resources Division of the U.S. Geological Survey undertook three pilot projects to evaluate electronic report processing systems as a means to improve the quality and timeliness of reports pertaining to water resources investigations. The three projects selected for study included the use of the following configuration...
Hydrogeology of the Point Lookout Sandstone in the San Juan structural basin, New Mexico, Colorado, Arizona, and Utah
Steven D. Craigg, W. L. Dam, J. M. Kernodle, C. R. Thorn, G. W. Levings
1990, Hydrologic Atlas 720-G
This report is one in a series resulting from the U.S. Geological Survey's Regional Aquifer-System Analysis (RASA) study of the San Juan structural basin that began in October 1984. Previous reports in the series describe the hydrogeology of the Dakota Sandstone (Craigg and others, 1989), Morrison Formation (Dam and others,...
Hydrogeochemical data from an acidic deposition study at McDonalds Branch basin in the New Jersey Pinelands, 1983-86
D. G. Lord, J. L. Barringer, P.A. Johnsson, P. F. Schuster, R.L. Walker, J.E. Fairchild, B.N. Sroka, Eric Jacobsen
1990, Open-File Report 88-500
Data from a 1983-86 acidic-deposition study at McDonalds Branch basin, a small (2.35-sq-mi) forested watershed in Lebanon State Forest, New Jersey include mineralogy of soil and depositional clays; physical and chemical analyses of soils; hydrologic measurements (precipitation and throughfall amounts, stream stage and discharge, and water-table altitudes); and water quality...
Precipitation Data for the Mount St. Helens Area, Washington--1981-86
Mark A. Uhrich
1990, Open-File Report 90-117
This report is a compilation of precipitation data from U.S. Geological Survey telemetered 'Early Flood Warning' sites near Mount St. Helens, Washington, and from telemetered hydrologic data sites in the Toutle River and Muddy River basins for the years 1981-86. It also includes precipitation data for 1981-86 from non-telemetered recording...
Water type and concentration of dissolved solids, chloride, and sulfate in water from the St. Francois aquifer in Missouri, Arkansas, Kansas, and Oklahoma
Jeffrey L. Imes, Jerri V. Davis
1990, Hydrologic Atlas 711-J
The St. Francois aquifer, the lowermost of three regional aquifers that form part of the Ozark Plateaus aquifer system, is composed of water-bearing sandstone and dolostone of Late Cambrian age. The aquifer was studied as part of the Central Midwest Regional Aquifer-System Analysis (CMRASA, Jorgensen and Signor, 1981), a study...
Results of test drilling and hydrologic monitoring in the Indian Bathtub area, Owyhee County, southwestern Idaho, January 1989 through September 1990
H.W. Young, M.L. Jones, D. J. Parliman, A.M. Tungate
1990, Open-File Report 90-597
This report presents data collected during the period January 1989 through September 1990 from eight test holes and selected thermal-water wells and springs in the Indian Bathtub area, southwestern Idaho. The data include completion, lithologic, and gamma logs for eight test holes, hydrographs of water levels in the test holes...
U.S. Geological Survey National Computer Technology Meeting; Program and abstracts, May 7-11, 1990
B. H. Balthrop (compiler), E.G. Baker
1990, Open-File Report 90-161
Computer-related information from all Divisions of the U.S. Geological Survey are discussed in this compilation of abstracts. Some of the topics addressed are system administration; distributed information systems and data bases, both current (1990) and proposed; hydrologic applications; national water information systems; geographic information systems applications and techniques. The report...
A summary of water-resources activities of the U.S. Geological Survey in Iowa; fiscal year 1990
1990, Open-File Report 90-583
Water resources activities of the U.S. Geological Survey in Iowa consist of collecting hydrologic data and conducting interpretive studies. Hydrologic investigations in Iowa are made through three basic types of projects: (1) hydrologic data-collection programs; (2) local or areal hydrologic studies; and (3) statewide or regional investigations. These projects are...
