7 2017 FCE Contest Guess the 2017 FCE for the new Cowlitz Falls Northshore Collector One guess per species (steelhead, coho, Chinook) to nearest % FCE. Winners announced at the 2018 CFWSAC Nearest Guess wins a fishy prize. Ties will be drawn from hat. Raw FCE= # Released/ # Detected for whole season

8 History and Purpose of Cowlitz River Projects John Serl WDFW Cowlitz M&E Program Lead April 20, 2017

9 Washington Idaho Oregon

10 Fisheries Terms Anadromy (Anadromous) Fish move from saltwater to freshwater to spawn as adults. Smolts Out-migrating juvenile salmonids that have undergone physiological changes to prepare them for life in saltwater Silvery appearance Black banding

11 Fisheries Terms NOR Natural Origin Recruits HOR Hatchery Origin Recruits phos proportion Hatchery Origin Spawners pnob proportion Natural Origin Brood PNI proportion Natural Influence = pnob/(phos+pnob)

27 Cowlitz River ESA Listed Populations Lower Columbia River, Threatened Winter Steelhead Chinook (spring and fall) Coho Chum 2005 Eulachon

28 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

29 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

30 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!

31 Population Recovery Designations Primary PNI>0.67, phos<5% or phos,pnob/2 Contributing PNI>0.60, phos <10% or pnob Stabilizing phos

33 PNI Natural Environment Hatchery Environment

34 Hatchery Production must fit with Size of Natural Population Size of Natural Population Size of Hatchery Program

35 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
