• Valley confinement

• Predominantly bedrock vs alluvial channel boundaries

• Extent of mining disturbance and existing infrastructure

• Channel gradient and confinement

• Alluvial channel features

• Floodplain Inundation

• Existing riparian vegetation

• Summer mainstem thermal suitability

• Proximity to major tributaries and other cold water refugia

• Existing spawning and rearing habitat

• Priorities identified by Salmon River Collaborative In-stream
