1. Science Policy Exchange
Mainstem Passage
and Survival
Sep 12-13, 2007

2. Alternative Conceptual Foundation Return to the River (1996; 2006)
Salmonid life history diversity and habitat diversity are linked
Increases in habitat abundance, diversity, and connectivity increase salmonid life history diversity
Increases in habitat and life history diversity increase salmon production
Increased abundance and production increase resilience
Sep 12-13, 2007

3. Spring Chinook spawning habitat
FWP Assumptions
Habitat-based program
rebuilding naturally producing fish populations by protecting and restoring habitats, including anadromous fish migration corridors
Juvenile and Adult Passage
Fish passage and transportation, should protect biological diversity across the range of species, stocks and life-history types
Natural Processes
Mainstem hydrosystem operations and fish passage efforts should be directed at re-establishing natural river processes where feasible
Protect and Expand Mainstem Spawning and Rearing Habitat
Spring Chinook spawning habitat
Upper Imnaha Subbasin
