Tacoma Power Settlement Agreement 2000 Focus on Recovery of Natural Populations Meet Fisheries Obligations by: Provide Effective Juvenile and Adult Passage o 95% Fish Passage Survival (75% min with BAT) Improve Habitat Maintain Hatchery Production Replace Unavoidable Losses Sustainable Fisheries
More Plans Fisheries and Hatcheries Management Plan 2006, 2011 update, 2017 update Monitoring and Evaluation Annual Project Review to set Hatchery Production LCFRB/NOAA Recovery Plan WDFW Fisheries and Hatchery Reform Policy Hatchery Scientific Review Group guidelines
HSRG Guidelines Fit Hatchery Production to Natural Population Population Type Integrated or Segregated Primary, Contributing, Stabilizing HSRG Rule Sets Natural Population Abundance This is what we estimate, Here is where data is used for management!
Population Recovery Designations Primary PNI>0.67, phos<5% or phos,pnob/2 Contributing PNI>0.60, phos <10% or pnob Stabilizing phos

Hatchery Production must fit with Size of Natural Population Size of Natural Population Size of Hatchery Program
How To Increase Natural Population? Recolonize Habitat Restore Passage (e.g.. Upper Cowlitz) Improve Passage (e.g.. Tilton River) Remove Barriers (e.g. Culverts) Improve Habitat Reduce Harvest Improve Fitness/Productivity
