  1. Tucannon Endemic Steelhead – An Integrated Program picture

  2. Background • ESA listings (Snake, Mid-Columbia) • 1999 Hatchery Bi-OP ruled that LSRCP steelhead stocks constituted “jeopardy” to the wild populations (Snake ESU), new broodstocks (localized) should be pursued. • Hatchery production stock (LFH and Wallowa) returns were generally exceeding LSRCP Goal’s. • Started test trapping for endemic broodstock feasibility on the Tucannon and Touchet rivers (1999). • Interim agreements with co-managers • 5-year test to evaluate each before programs were expanded • 50,000 smolt release per year • HGMP development • Reductions in standard production stocks while increasing localized stocks

  4. Evaluation of Program Success • Pit tag data • Trap site data

  5. Long-term and Current Objectives? • Long Term • 150,000 total release goal • (50,000 conservation component) • (100,000 marked for harvest) • Current • 75,000 for conservation

  6. Tucannon River Harvest Opportunities • Lyons Ferry Stock Steelhead: Last juvenile released in lower Tucannon River occurred in 2009 (100,000) • Tucannon Stock Steelhead: Release juveniles for harvest?

  7. Facility Impacts • Hatchery improvements / upgrades (LSRCP obligated until BPA picks up conservation component?) • Tucannon -vs- Lyons Ferry Hatchery • Rearing to full term

  8. Questions ? • Could LSRCP or other co-managers helped in this situation to avoid the loss of fishing opportunities? • Will we be able to move forward with the harvest component without an up to date WDFW Steelhead management plan in place?
