Ground-water levels in the alluvial aquifer at Louisville, Kentucky, 1982-87
R.J. Faust, M. A. Lyverse
1987, Water-Resources Investigations Report 87-4197
Water level data have been collected in the alluvial aquifer at Louisville, Kentucky by the U.S. Geological Survey since 1943. Interpretations of these data have been published in several reports by the Survey, but none have been published since 1983. Contour maps and hydrographs are presented in this report to...
Potentiometric surface of the Aquia Aquifer in southern Maryland during the Fall of 1986
F. K. Mack, D. C. Andreasen, S. E. Curtin, J. C. Wheeler
1987, Water-Resources Investigations Report 87-4214
Thr potentiometric map is highlighted with indications concerning: (1) outcrop areas of the Aquia aquifer; (2) the potentiometric contour of the aquifer; (3) observation and/or supply wells yielding < 10,000 gallons/day (gpd); and (4) other supply wells with yields > 10,000 gpd. (Lantz-PTT)...
Potentiometric surface of the Magothy Aquifer in southern Maryland during the Fall of 1986
F. K. Mack, D. C. Andreasen, S. E. Curtin, J. C. Wheeler
1987, Water-Resources Investigations Report 87-4216
The potentiometric map is highlighted with indications concerning: (1) outcrop areas of the Magothy aquifer; (2) the potentiometric contour of the aquifer; (3) observation and/or supply wells yielding < 10,000 gallons/day (gpd); and (4) other supply wells with yields > 10,000 gpd. (Lantz-PTT)...
Seismicity map of the state of Ohio
C. W. Stover, B.G. Reagor, S. T. Algermissen
1987, Miscellaneous Field Studies Map 1975
This map is one of a series of seismicity maps produced by the U. S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000. This map shows only those earthquakes with epicenters located within the boundaries of Ohio, even though earthquakes...
Overview of water resources in Owens Valley, California
L.S. Rogers
1987, Water-Resources Investigations Report 86-4357
In 1982-84, a water resources appraisal of Owens Valley was made by using available hydrologic information. Results of the appraisal provided an overview of water resources in Owens Valley; a better understanding of the groundwater system; and a framework for additional studies. Owens Valley is in east-central California and is...
Hydrogeology of the Socorro and La Jencia basins, Socorro County, New Mexico
Scott K. Anderholm
1987, Water-Resources Investigations Report 84-4342
The Socorro and La Jencia Basins are located in central Socorro County, New Mexico. The principal aquifer system in the Socorro and La Jencia Basins consists of, in descending order, the shallow aquifer, the Popotosa confining bed, and the Popotosa aquifer. The minor aquifer systems, which are dominant along the...
Maps showing anomalous copper concentrations in stream sediments and heavy-mineral concentrates from the Ajo and Lukeville 1 degree by 2 degrees quadrangles, Arizona
P. K. Theobald, H. N. Barton
1987, Miscellaneous Field Studies Map 1834-C
This map is part of a folio of maps of the Ajo and Lukeville 1 ° x 2° quadrangles, Arizona, prepared under the Conterminous United States Mineral Assessment Program. Other publications in this folio include U.S. Geological Survey Miscellaneous Field Studies Maps MF-1831-A and MF-1831-B and Open-File Reports 82-119, 82–599,...
Habitat Suitability Index Models: Black Bear, Upper Great Lakes Region
Lynn L. Rogers, Arthur W. Allen
1987, FWS/OBS 82/10.144
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the black bear (Ursus americanus). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum...
Flood characteristics of the Buffalo River at Tyler Bend, Arkansas
Braxtel L. Neely
1987, Water-Resources Investigations Report 87-4180
The Buffalo River is located in the Ozark Mountains in north-central Arkansas. Tyler Bend is on the Buffalo River about 1.5 miles upstream from U.S. Highway 65. The National Park Service is developing several recreational park sites along this scenic river. The magnitude, frequency, duration and velocities of floods are...
Potentiometric surface of the upper Floridan aquifer in Florida and in parts of Georgia, South Carolina, and Alabama, May 1985
Peter W. Bush, G. Lynn Barr, John S. Clarke, Richard H. Johnston
1987, Water-Resources Investigations Report 86-4316
A map, constructed as a part of the Floridan Regional Aquifer-System Analysis (RASA), shows the potentiometric surface of the Upper Floridan aquifer for May 1985. It is based on measurements of water level or artesian pressure made in about 2 ,500 wells during the period May 13 to 24, 1985....
Habitat Suitability Index Models: American alligator
John D. Newsom, Ted Joanen, Rebecca J. Howard
1987, FWS/OBS 82/10.136
A review and synthesis of existing information were used to develop a model for evaluating American alligator habitat quality. The model is applicable in marshes along the northern Gulf of Mexico. It is scaled to produce an index between 0 (unsuitable habitat) and 1.0 (optimal habitat). Habitat suitability index models...
Traveltime and dispersion in the Illinois River, Marseilles to Peoria, Illinois
E.E. Zuehls
1987, Water-Resources Investigations Report 87-4106
Traveltime in 89.3 mi of the Illinois River between Marseilles Dam and Peoria Dam was measured using rhodamine-WT dye. On each of four subreaches, dye-tracer measurements were made at approximately 50- and 85% flow duration in 1978, 1979, and 1985. The dye-tracer data were used to develop a method for...
