Potentiometric surface of the Floridan Aquifer, Southwest Florida Water Management District, May 1983
G. L. Barr, George R. Schiner
1983, Open-File Report 83-547
Maps of the potentiometric surface of the Floridan aquifer in west-central Florida are prepared semiannually by the U.S. Geological Survey in cooperation with the Southwest Florida Water Management District. Maps for May and September show, respectively, the potentiometric surface of the normally expected annual low and high water level conditions....
Occurrence and use of ground water in the Venice-Englewood area, Sarasota and Charlotte counties, Florida
Horace Sutcliffe, Thomas H. Thompson
1983, Open-File Report 82-700
In a 75-square-mile area of coastal Sarasota and Charlotte Counties, demand for water is increasing. Groundwater, the principal source of supply, is distributed largely by public water systems. Principal water-bearing formations in descending order, include the surficial aquifer, artesian zone 1 in the Tamiami Formation, zone 2 in the upper...
Geologic and aeromagnetic maps and mineral resource potential survey of the Blackjack Springs Wilderness, Vilas County, Wisconsin
Klaus J. Schulz
1983, Miscellaneous Field Studies Map 1592
The mineral resource potential of the Blackjack Springs Wilderness in the Nicolet National Forest, Vilas County, Wisc., was evaluated in 1982.  No bedrock exposures are known in or near the wilderness.  Geophysical data and regional geologic relations suggest that the area consists mostly of recrystallized and deformed mafic volcanic rocks...
Multichannel seismic measurements on the northern edge of the Bahaman-Cuban collision zone
M. M. Ball, editor(s)
1983, Open-File Report 83-23
This paper presents geophysical data obtained, in the western reaches of the Old Bahama Channel separating Cuba and the Bahamas (Figure 1). These data were collected as part of an ongoing investigation of Caribbean and Bahaman geology primarily conducted by University of Miami and the U.S. Geological Survey (USGS). The...
Hydrology of the Jasper (Miocene) Aquifer in the Southeast Texas coastal plain
E.T. Baker
1983, Open-File Report 83-677
The Jasper (Miocene) aquifer is one of several important hydrologic units in the Gulf Coastal Plain. Because the Jasper aquifer underlies shallower aquifers in many areas, regional water withdrawals from the Jasper are not significant; however, it is capable of yielding 3,000 gallons per minute (200 liters per second) or...
Index of faults of Cretaceous and Cenozoic age in the eastern United States
David C. Prowell
1983, Miscellaneous Field Studies Map 1269
The information in this report was collected between 1974 and 1982 as part of the Reactor Hazards Program of the U.S. Geological Survey (USGS). This program was initiated to delineate and assess geologic hazards that could be particularly detrimental to major constructions, especially nuclear reactors. Faults are of principal interest...
Work plan for the Sangamon River basin, Illinois
J. K. Stamer, Dean M. Mades
1983, Open-File Report 82-693
The U.S. Geological Survey, in cooperation with the Division of Water Resources of the Illinois Department of Transportation and other State agencies, recognizes the need for basin-type assessments in Illinois. This report describes a plan of study for a water-resource assessment of the Sangamon River basin in central Illinois. The...
