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...
Reconnaissance geology of the Al Ufayriyah quadrangle, sheet 20/42 A, Kingdom of Saudi Arabia
Robert C. Greene
1983, Open-File Report 83-295
The Al Ufayriyah quadrangle is located in the Najd Plateau of southwestern Saudi Arabia between lat 20?30' and 21?00' N.,. long 42?00' and 42?30' E. Two-thirds of the quadrangle is underlain by Precambrian metasedimentary, metavolcanic, plutonic, and hypabyssal intrusive rocks; this area is in part mountainous and in part uneven...
Water and streambed-material data, Eagle Creek watershed, Indiana, August 1980-December 1982
David J. Wangsness
1983, Open-File Report 83-215
Water quality studies within the Eagle Creek watershed, Indiana, were done by the U.S. Geological Survey in August 1980, October 1982, and December 1982 in cooperation with the city of Indianapolis, Department of Public Works. Streambed-material and water samples were collected from Finley and Eagle Creeks at various flow rates...
Habitat Suitability Index Models: Roseate spoonbill
James C. Lewis
1983, FWS/OBS 82/10.50
The roseate spoonbill is a long-legged wading bird with a height of approximately 80 cm (31.5 inches), a wingspan of 1.3 m (4.3 ft), and a weight of 1.6 kg (3.5 Ib }. The bill is narrower near the base (2-3 em, 0.8-1.2 inches) than at the flattened tip (5...
Habitat Suitability Index Models: Alewife and blueback herring
Garland B. Pardue
1983, FWS/OBS 82/10.58
Alewives and blueback herring are anadromous clupeids found along the Atlantic coast in marine, estuarine, and riverine habitats, depending upon life stage. Both are important commercial species, used fresh or salted for human consumption, and used as crab bait, fish meal (particularly in animal food manufacturing), and fish oil. Alewife...
Preliminary stage-discharge relations for Tombigbee River at Gainesville Dam, near Gainesville, Alabama
G. H. Nelson, C. O. Ming
1983, Open-File Report 83-942
The construction of Gainesville Dam and other related channel alterations, completed in 1979, has resulted in changes to the stage-discharge relations in the vicinity. The lack of current-meter measurements, coupled with backwater conditions, makes definition of a single stage-discharge relation impossible. However, limit curves can be defined that would encompass...
Habitat Suitability Index Models: Smallmouth bass
Elizabeth A. Edwards, Glen Gebhart, O. Eugene Maughan
1983, FWS/OBS 82/10.36
A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for Smallmouth bass (Micropterus dolomieui), a freshwater species. The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) and 1 (optimally suitable habitat) for freshwater areas of the continental...

I.L. Burmeister, V.L. Spiers, P. J. Soenksen, W.J. Matthes
1983, Water Data Report IA-82-1
Water resources data for the 1982 water year for Iowa consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels in wells. This report contains discharge records for 116 gaging stations; stage and contents for 7 lakes and reservoirs; water...
Literature assessment of the Charlotte Harbor estuarine system and surrounding area, Southwest Florida
Yvonne E. Stoker, George A. Karavitis
1983, Open-File Report 83-127
The Governor of Florida established the Charlotte Harbor Resource Planning and Management committee to recommend the course of action Florida should take in planning for potential growth in the rapidly growing area surrounding Charlotte Harbor. In May 1981, the U.S. Geological Survey began a planning study to determine detailed hydrologic...
Geology of faults exposed in trenches in Crater Flat, Nye County, Nevada
W. C. Swadley, D. L. Hoover
1983, Open-File Report 83-608
Study of three trenches excavated across two faults along the eastern edge of Crater Flat indicates that the main fault movement offset unit QTa in trench 1 at least 2.4 m down to the west, and occurred about 1.1 m.y. ago, as indicated by included basalt ash. Later fault movement,...
