Habitat Suitability Index Models: Muskrat
Arthur W. Allen, Robert D. Hoffman
1984, FWS/OBS 82/10.46
The muskrat (Ondatra zibethicus) is the most valuable semi-aquatic furbearer in North America, with a total fur trade income in the millions of dollars (Willner et al. 1980). With the exception of Florida, and coastal Georgia and South Carol ina, native and introduced populations of muskrats occur throughout most of...
Habitat Suitability Index Models: Spotted seatrout
Paul T. Kostecki
1984, FWS/OBS 82/10.75
The estuarine spotted seatrout, a primarily estuarine species, is one of the most important sport and commercial fishes in coastal Gulf of Mexico waters (Arnold et a1. 1976). Spotted seatrout rank second by weight in catches by U.S. saltwater sport fishermen (National Marine Fisheries Services 1981) ....
Habitat Suitability Index Models and Instream Flow Suitability Curves: Spotted bass
Thomas E. McMahon, Glen Gebhart, O. Eugene Maughan, Patrick C. Nelson
1984, FWS/OBS 82/10.72
The Habitat Suitability Index (HSI) models presented in this publication aid in identifying habitat variable important to the growth and survival of spotted bass (Micropterus punctulatus). Facts, ideas, and concepts obtained from the research literature and expert reviews are synthesized and presented in a format that can be used for...
Habitat Suitability Index Models: The Arizona guild and layers of habitat models
Henry L. Short
1984, FWS/OBS 82/10.70
This document is part of the Habitat Suitability Index Models Series, which provides habitat information useful for impact assessment and habitat management. Both of the models described in this report are based on the significant association of Wildlife species with vegetation structure. The models compare the structure in the study...
Geochronometric and lead isotope data on samples from the Wallace 1 degree by 2 degrees Quadrangle, Montana and Idaho
R. F. Marvin, R. E. Zartman, J. D. Obradovich, J. E. Harrison
1984, Miscellaneous Field Studies Map 1354-G
Most of the bedrock in the Wallace quadrangle belongs to the Belt Supergroup, a thick (about 18,000 m) sequence of generally fine-grained clastic and carbonate rocks of Middle Proterozoic age.  Regional metamorphism prior to Cambrian time prograded the Belt rocks to greenschist facies, and some metal-bearing veins were emplaced in...
A reconnaissance study of saltwater contamination in the El Dorado aquifer, Union County, Arkansas
Matthew E. Broom, T. F. Kraemer, William V. Bush
1984, Water-Resources Investigations Report 84-4012
Since 1960 chloride concentrations in the El Dorado aquifer have increased near El Dorado, Arkansas. The aquifer is a major source for municipal and industrial water supply in Union County. Greatest withdrawal occurs near El Dorado. Because of this withdrawal, the potentiometric surface at El Dorado has been lowered more...
Definition of boundary and initial conditions in the analysis of saturated ground-water flow systems; an introduction
O.L. Franke, T. E. Reilly, G.D. Bennett
1984, Open-File Report 84-458
Accurate definition of boundary and initial conditions is an essential part of conceptualizing and modeling ground-water flow systems. This report explains the properties of the seven most common boundary conditions encountered in ground-water systems and discusses major aspects of their application. It also discusses the significance and specification of initial...
Geohydrologic data for test well USW G-4, Yucca Mountain area, Nye County, Nevada
C.B. Bentley
1984, Open-File Report 84-63
Data are presented on drilling operations, lithology, borehole geophysics, hydrologic monitoring, core analysis, water chemistry, pumping tests, and packer-injection tests for test well USW G-4. The well is one of a series of test wells drilled in and near the southwestern part of the Nevada Test Site, Nye County, Nevada,...
