INTRODUCTION As part of the National Water-Use Information Program, the U.S. Geological Survey (USGS) stores water-use data in standardized format for different categories of water use. The data base (Site Specific Water Use Data System) is updated annually or as more current water-use information becomes available. Information about amounts of...

Synoptic-study measurements of unsteady streamflow and dye concentrations were collected on a 49.4-mile reach of the Fox River in south-eastern Wisconsin and northeastern Illinois in October and November 1990. The study area included the Fox River and its major tributaries from Wilmot, Wis., downstream to South Elgin, Ill. The measurements...

Documentation of model input values and sample output used during a conceptual evaluation of the regional ground-water flow in the carbonate-rock province of the Great Basin, Nevada, Utah, and adjacent states, was revised from previously published Open-File Report 91-479. The documentation, consisting of a listing of input values and sample...

This report, one in a series of annual reports, provides current information about the National Research Program (NRP) of the U.S. Geological Survey's Water Resources Division (WRD) during fiscal year 1992. Organized by NRP's six research disciplines, the volume contains a summary of the problem, objective, approach, and progress for...

Oxygen-isotope compositions of authigenic-layer silicates (<2-micrometer fraction) extracted from Mississippian and Pennsylvanian sandstones in the Lower Peninsula of Michigan were determined. Petrographic and scanning-electron-microscope examinations, and X-ray diffractograms show that chlorite and kaolinite are the most common authigenic-layer silicates in Mississippian sandstones. The range of oxygen-isotope compositions of chlorite and...

In 1990, a 3-year investigation was begun in North Carolina to: (1) develop a model for computing flows in the lower 67 mi of the Roanoke River; (2) characterize water-quality conditions in Albemarle Sound; and (3) describe the circulation regime of Albemarle Sound, particularly in relation to inflows. This report...

About 1,000 million gallons of water per day moves toward or into ground-water bodies of Kilauea Volcano from the lavas of Mauna Loa Volcano. This movement continues only to the northern boundaries of the east and southwest rift zones of Kilauea, where a substantial quantity of ground water is deflected...

Water and bottom-sediment samples were collected at 26 sites in the 65-square-mile High Point Lake watershed area of Guilford County, North Carolina, from December 1988 through December 1989. Sampling locations included 10 stream sites, 8 lake sites, and 8 ground-water sites. Generally, six steady-flow samples were collected at each stream...

Current activities of the Pennsylvania District of the USGS are described and include information on current projects, such as project objectives, approach, progress and plans, project location, cooperators, period of project, and project chief. Basic-data programs for surface water, ground water, and quality of water also are described. Also included...
