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

This report contains four major parts: (1) a Habitat Use Information
section which provides a general summary of the life history of chum salmon;
(2) a Specific Habitat Requirements section which provides a detailed discussion of habitat needs for each 1ife stage in freshwater; (3) a HSI Model
section which presents hypothesized relationships between various environmental variables and habitat quality for chum salmon; and (4) an Instream Flow Incremental Methodology (I FIM) section whi ch di scusses use of Suitability Index Graphs from the HSI model with IFIM and provides additional SI graphs developed specifically for analysis of chum salmon habitat via the IFIM.
