Yakima River• Habitat degradation:
– Dams and irrigation canals– Bank armoring– High temperatures in downstream reaches– Invasive species
• Restoration action:– Supplementation in 1997– Acclimation facilities to extend spawning
distribution

Objectives• Develop and evaluate extensive survey
methods for lotic habitat and fishes
• Relate physical habitat to spawning site selection and homing by wild- and hatchery-origin salmon
• Link community structure of resident fishes to habitats associated with salmon spawning distribution
![Page 6: Linking physical habitat characteristics to Chinook spawning distribution in the Yakima River](https://reader036.fdocuments.in/reader036/viewer/2022081504/56814aa2550346895db7b551/html5/thumbnails/6.jpg)
Methods
• Extensive habitat and snorkel survey (2007)
• Intensive survey (2008)
• Carcass and redd surveys (2002 – 2008)
• Depth and temperature profiling (2009)

Preliminary conclusions• Hatchery- and wild-origin Chinook have similar
spawning distributions at scales ≥ 1km• The influence of habitat factors on spawning site
selection depends on spatial scale• Redd density is correlated with rainbow trout
distribution at broad scales (4 km)
