Habitat Suitability Index Models and Instream Flow Suitability Curves: Chinook Salmon

This publication contains habitat models constructed and information
compiled for two distinctly different purposes. The Habitat Suitability Index
(HSI) model by Raleigh and Miller contains 17 habitat variables for chinook
salmon by life stage. The HSI model provides an objective quantifiable method
of assessing the existing habitat conditions for chinook salmon within a study
area by measuring how well each habitat variable meets the habitat requirements of the species by life stage. The model thus provides an objective basis for predicting probable project impacts, documenting post project impacts, and guiding habitat protection, mitigation, enhancement, and management decisions.
