Objectives
• Create a new hatchery line from Wallowa stock returning to Grande Ronde in autumn. Autumn Line may stray less and improve the autumn fishery.
• Compare performance of Autumn Line with the standard Wallowa Stock.
Is smolt outmigration survival similar? Does the Autumn Line return earlier? Are smolt-to-adult survival rates similar? Does the Autumn Line stray at a lower rate?

PIT Tag TechnologyWhat have we learned?
VSP measures• Life stage survival• Freshwater productivity• Ocean survival• Hatchery fraction• Life history designation
Management solutions• In season fishery predictions• Developed a new hatchery stock• Hatchery strays• Migration corridor contributes significant mortality
– Juveniles– Adult steelhead wandering
• Freshwater survival is still limiting– John Day vs. Grande Ronde Chinook
