Operation of hydrologic data collection stations by the U.S. Geological Survey in 1983
Alberto Condes de la Torre
1983, Open-File Report 83-862
The U.S. Geological Survey operated hydrologic data collection stations during 1983 in response to the needs of all levels of Government for hydrologic information. Surface-water discharge was determined at 11,076 stations; stage data on streams, reservoirs, and lakes were recorded at 2,136 stations; and surface-water quality was determined at 4,610...
Mineral resource potential map of the Sugarloaf Roadless Area, San Bernardino County, California
Robert E. Powell, Jonathan C. Matti, Brett F. Cox, Howard W. Oliver, Alexander Wagini, Harry W. Campbell
1983, Miscellaneous Field Studies Map 1606-A
Geologic, geochemical, and geophysical investigations and a survey of mines and prospects indicate that the Sugaloaf Roadless Area contains subeconomic graphite and magnesian marble resources. Parts of the area have a low potential for the occurrence of additional low-grade graphite resources, but there is no potential for additional magnesian marble...
Suspended-sediment data in the Salt River basin, Missouri
Wayne R. Berkas
1983, Open-File Report 83-275
Suspended-sediment data collected at six stations in the Salt River basin during 1980-82 are presented. The estimated average annual suspended-sediment load is 1,390,000 tons per year from a geomorphic examination, and 1,330,000 tons per year from periodic sampling at Salt River near Monroe City, Mo. The suspended-sediment load from the...
Slides showing quantitative models for mineral-resource assessment of the Rolla 1 degree x 2 degrees Quadrangle, Missouri
Kim-Marie Walker, S.K. Jenson, J. R. Francica, D. A. Hastings, C. M. Trautwein, W. P. Pratt
1983, Open-File Report 83-387
Th.is report consists of nineteen 35-mm color slides sh.owing digital synthesis and quantitative modeling of five geologic recognition criteria for assessment of Mississippi Valley-type resource potential in the Rolla 1° x 2° quadrangle, Missouri. The digital synthesis and quantitative modeling (Pratt and others, 1982) was done to supplement an earlier...
Habitat Suitability Index Models: Williamson's sapsucker
Patrick J. Sousa
1983, FWS/OBS 82/10.47
The Williamson's sapsucker (Sphyrapicus thyroideus) " ... inhabits middle elevation pine forests and high elevation spruce-fir forests" (Crockett 1975:111) as well as aspen stands (Hansley 1977; Hansley, pers. comm.) throughout its range in the western Uni ted States. The Rocky Mounta in subspecies (S. t. nataliae) exhibits altitudinal and latitudinal...
Habitat Suitability Index Models: Southern red-backed vole (western United States)
Arthur W. Allen
1983, FWS/OBS 82/10.42
Habitat preferences of the southern red-backed vole (Clethrionomys gapperi) are described in this publication, which is one of a series of Habitat Suitability Index (HSI) models. A review and synthesis of the literature is followed by development of a model of the species-habitat requirements of the southern red-backed vole. Habitat suitability...
Habitat Suitability Information: Blacknose dace
Joan G. Trial, Jon G. Stanley, Mary Batcheller, Gary Gebhart, O. Eugene Maughan, Patrick C. Nelson
1983, FWS/OBS 82/10.41
A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for Blacknose dace, a freshwater species. The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for freshwater, marine, and estuarine areas of the...
Habitat Suitability Index Models: Bigmouth buffalo
Elizabeth A. Edwards
1983, FWS/OBS 82/10.34
A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for Bigmouth buffalo (Ictiobus cyprinellus), a freshwater fish. The models are scaled to produce an indices of habitat suitability between 0 (unsuitable habitat) and 1 (optimally suitable habitat) for freshwater areas of the...
Water resources data, Missouri, water year 1982
L.A. Waite, D.O. Hatten, P. W. Cross
1983, Water Data Report MO-82-1
Water resources data for the 1982 water year for Missouri consist of records of stage, discharge, and water quality of lakes and reservoirs; contains records for water discharge at 112 gaging stations; stage and contents at 9 lakes and reservoirs; water quality at 30 gaging stations (including 1 lake) and...
