  1. Efforts to establish a local steelhead broodstock in the Okanogan River In the Okanogan River and to initiate a steelhead kelt reconditioning program C. Fisher, J. Marco, and J. Arterburn

  3. ResourceProblems Migration barriers to anadromous fish

  4. Excessive runoff and sediment from roads

  5. High stream temperature, low dissolved oxygen

  6. Increase in canopy closure from 8.4% to 30%

  7. Locally-adapted broodstock program (Phase I) 1) Collection in Omak Creek & Okanogan River 2) Collection of 16 adult steelhead (8 male, 8 females) 3) Differentially marked – based on parental origin 4) Monitoring returning adults and spawning success

  8. Increase in canopy closure from 8.4% to 30%

  9. Collection of broodstock, in Omak Creek and Okanogan River Picket weir Trap net Angling

  10. Collection from March 14 to May 2 (total 29 days)

  11. Omak Creek – Picket weir ~ 80 cfs – March 16

  12. 8 steelhead collected [4 males (1W, 3H); 4 females (2W*, 2H)]

  13. Spawning – April 11 1 wild male X 3 females (1H, 2W*) Cross (m x f) Egg take Egg loss Ponding loss W x W 6,600 100% n/a W x W 3,409 2.6% 12 W x H 6,000 1.4% 8

  14. Broodstock virology testing: (tissues, ovarian fluids) EHN, IHN, IPN, OMV, SVC, VHS

  15. Allproduction will be marked (differentially) with Elastomer tags

  16. Monitoring & Evaluation:12 years Assessments: Returning adults Redd surveys Juvenile abundance Smolt origin

  17. Recommendations 1) Improve ability to collect broodstock 2) Ability to collect smolts 3) Initiate a kelt reconditioning program
