Abstract
The Aquatics and Riparian Science Teams analyzed the seven alternatives by evaluating their effectiveness in sustaining aquatic ecosystem structure and function, and their expected effect on 25 taxa of native fishes. Our analysis focused on alternatives as defined in Chapter 3 of the Preliminary Draft Environmental Impact Statements (EISs) (USDA and USDI 1996a, 1996b). The analysis consisted of three steps. In step one, we identified the level of protection, maintenance, or restoration of aquatic and riparian habitats offered by each alternative. In step two, we identified expected changes in distribution and status of seven widely-distributed salmonid species that would likely result from implementation of each alternative. Step three involved a similar, though less intensive, effort to identify expected changes in the populations of 18 more narrowly-distributed fish species of special concern. Each step built on the preceding one, as the sections below demonstrate.
