Siskiyou Region – Landscape & Habitat
- Multiple Ecoregions- Ecological Ties- Less Precipitation- Higher Temperatures- Steeper Stream Gradients- Erosive Geology- Human Footprint

Summer and Winter RunsNative Fish Status Report (2005)Rogue-South Coast Multispecies Plan (in progress)
- Migrate among small and large tributaries and the mainstem Rogue
- Capable of using seasonally-available water- Temperature & Passage- Conservative harvest regulations
Half Pounders- Only in Oregon and some N. California streams- Most Rogue summer steelhead; many Rogue winter
steelhead- Size of Rogue Steelhead - Popular fishery in lower and middle Rogue
