  1. Yakima River Fall Chinook Supplementation 2009-10 Melinda DavisYakama Nation, YKFP

  2. Objectives To supplement and enhance existing stocks of Yakima River fall Chinook, while preserving the stock characteristics and fitness of targeted stocks and keeping ecological and genetic impacts to not-target species within specified limits.

  3. Yakima River Releases 99-10

  4. Fall Chinook Survival to McNary Dam (Neeley, 2005) * Brood-years 1998-2004, respectively. ** Main-Stem-Yakima Stock under Accelerated Rearing, Main-Stem-Yakima Stock under Conventional Rearing, and Marion Drain Stock

  5. Yakima River Releases 99-10

  6. Yearling vs Sub-yearling (Neeley, 2010) 74.3% 49.9% 28.4%

  7. 2009 Fall Chinook Returns

  8. 2009 Redd Surveys above Prosser 2007 Redd Surveys above Prosser • 1,132 over Prosser Dam • Yakima River- 321 Redds 55.1% Emerald Rd to Granger (RM70-83) 44.9% Granger to Zillah (RM83-91) 0% Zillah to SSD (RM91-104) 0% Union Gap (RM107-117) • Naches River- 0 Redds Wapatox Dam to Cowiche Dam 2,972 Adults over Prosser Dam • Yakima River- *218 Redds • 22 Emerald Rd to Granger (RM70-83) • 195 Granger to Zillah (RM83-91) • 1 Zillah to SSD (RM91-104) • 0 Union Gap (RM107-117) • Naches River- 0 Redds • Wapatox Dam to Cowiche Dam

  9. PNL Aerial Surveys 2009

  10. Marion Drain-70 Redds 34.3% above Hwy 97 65.7% below Hwy 97

  11. *No Surveys conducted in 2000

  12. Re-Establishing Summer Chinook in the Yakima River • Objective: To initiate investigation of the feasibility of establishing an early-run fall Chinook population in the Yakima River, with the goals being to: • Develop a naturally spawning adult population in the Yakima River between Sunnyside Dam and Roza Dam, and in the lower Naches River from the mouth to the Tieton River, and, • Increase the number of natural-origin returning summer-run adults in the lower Columbia, Zone 6, and the lower Yakima River contributing to harvest augmentation for both the tribal and sports fishery.

  13. WDFW Wells Hatchery

  14. YN Marion Drain Hatchery

  15. Summer Chinook Release N Released CWT only PIT Release 2008 180,911 170,000 30,000 6/12/09 2009 200,747 170,750 29,997 5/14/10 100% females tested for Virus and BKD Results: all keepers! Released from Stiles pond, lower Naches River

  16. (Neeley, 2010)

  17. 2010-11 Plans on-going • Acclimate summer chinook at Stiles pond, Naches River ~RM 3.4. • Continue In-basin Yearling vs. Subyearling releases from Prosser Hatchery. • Transfer up to 250,000 summer chinook eggs/milt from Wells Hatchery to Marion Drain Hatchery. • Redd Surveys on the Yakima River between Prosser and Roza Dams and lower Naches River. • Radio Tag Returning Adults at the Prosser Denil • Finalize and Submit Fall/Summer Chinook Master Plan for approval.

  18. 2010-11 Future Plans • Locate acclimation site in the lower river below Wanawish Dam (Horn Rapids) for out-of-basin fall chinook. • Establish a summer chinook mobile acclimation unit for use in the Yakima River near Skov Pond ~RM122. • Transistion from using broodstock from the LWS hatchery to Priest Rapids Hatchery, as recommended by both USFWS hatchery review and the HSRG.
