Geophysical logs for selected wells in the Picher Field, northeast Oklahoma and southeast Kansas
Scott C. Christenson, Tom B. Thomas, Myles D. Overton, Robert L. Goemaat, John S. Havens
1991, Open-File Report 91-213
The Roubidoux aquifer in northeastern Oklahoma is used extensively as a source of water for public supplies, commerce, industry, and rural water districts. The Roubidoux aquifer may be subject to contamination from abandoned lead and zinc mines of the Picher field. Water in flooded underground mines contains large concentrations of...

Flood characteristics of Mississippi streams
M. N. Landers, K.V. Wilson Jr.
1991, Water-Resources Investigations Report 91-4037
Flood magnitudes for selected recurrence intervals from 2 to 500 years were determined for 330 gaged sites in the study area where annual peak-flow records have been collected. The principal study area is Mississippi; however, selected data collected in adjoining States on streams draining into or from Mississippi are also...

Water Resources Division, U.S. Geological Survey
1991, Water Data Report FL-90-3B
Water resources data for the 1990 water year in Florida consist of continuous or daily discharge for 349 streams, periodic discharge for 40 streams, miscellaneous discharge for 75 streams, continuous or daily stage for 105 streams, continuous daily tide stage for 12 sites, periodic stage for 25 streams, peak discharge...
Geohydrology and ground-water resources of Philadelphia, Pennsylvania
Gary N. Paulachok
1991, Water Supply Paper 2346
The aquifers underlying the 134.6-square-mile city of Philadelphia are divided by the Fall Line into the unconsolidated aquifers (chiefly sand and gravel) of the Coastal Plain and the consolidated-rock aquifers (chiefly schist of the Wissahickon Formation) of the Piedmont. Ground water is present under confined and unconfined conditions. The principal...
Method for estimating low-flow characteristics of ungaged streams in Indiana
Leslie D. Arihood, Dale R. Glatfelter
1991, Water Supply Paper 2372
Equations for estimating the 7-day, 2-year and 7oday, 10-year low flows at sites on ungaged streams are presented. Regression analysis was used to develop equations relating basin characteristics and low-flow characteristics at 82 gaging stations. Significant basin characteristics in the equations are contributing drainage area and flow-duration ratio, which is...

James L. Wood, Jeffrey M. Fischer
1991, Open-File Report 91-189
Selected meteorological data were collected at a study site adjacent to a low-level radioactive-waste burial facility near Beatty, Nevada, for calendar year 1986. Data were collected in support of an ongoing study to estimate the potential for downward movement of radionuclides into the unsaturated sediments beneath waste-burial trenches at the...
