Habitat degradation:

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

Develop and evaluate extensive survey methods for lotic habitat and fishes

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

Hatchery- and wild-origin Chinook have similar spawning distributions at scales ≥ 1km

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)
