Abstract
This study was conducted in the Skagit River Basin to observe what types of side-channel habitat best support juvenile Chinook and other salmon species (Lowery et al.). The Skagit and Sauk-Suiattle river basins have a total of six independent spawning populations of Chinook Salmon. Chinook salmon have three distinct life histories represented by stream type (subyearling parr and yearling), and ocean type (fry) present within the Skagit River System. Differentiating life stage is used by the 45mm threshold, fish being <= 45mm parr being fry while fish > 45 mm being subyearling and yearling. Scale, otolith, observational and genetic data suggest the presence of three distinct life histories in the Skagit River Basin (SRSC and WDFW 2005, Zimmerman et al. 2015, Lowery et al. 2020).
