This document outlines the integrated program for the Tucannon endemic steelhead, including historical context on ESA listings and the impact of hatchery production. The program, initiated to address local stock jeopardy, involves testing for local broodstock feasibility while aiming to enhance wild populations. Strategies include releasing 50,000 smolts annually, developing HGMP, and pursuing genetic management improvements. Objectives include a long-term release goal of 150,000 steelhead, with considerations for harvest opportunities and hatchery upgrades to boost conservation efforts.

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

Evaluation of Program Success • Pit tag data • Trap site data
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
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?
Facility Impacts • Hatchery improvements / upgrades (LSRCP obligated until BPA picks up conservation component?) • Tucannon -vs- Lyons Ferry Hatchery • Rearing to full term
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?
