Mid Columbia Recovery Region

South Fork Tieton River The Middle Columbia Salmon Recovery Region is located in central Washington along the east slope of the Cascade Mountains. Forests and farms dominate the diverse terrain and dry, shrub-steppe hills that cover most of the region. It includes the Columbia River and its tributaries entering from the west and north from the Yakima River to the Big White Salmon River.

Major Factors Limiting Recovery

  • Degraded floodplain and channel structure
  • Riparian degradation
  • Degraded water quality and temperature
  • Impaired stream flows in tributaries
  • Barriers to fish passage in tributaries
  • Excessive sediment
  • Hydropower system mortality on Columbia River
  • Harvest impacts
  • Predator harassment of spawning fish
  • Influence of hatchery releases on natural origin populations


Hatchery and Harvest Priorities

Strategies for Recovery
The recovery plan proposes actions to reduce or mitigate the limiting factors and threats to steelhead survival throughout the life cycle:
  • Tributary Habitat: Protect highest quality habitats, maintain existing unimpaired healthy watersheds, and restore habitat conditions through passive and active measures.
  • Hydrosystem: Improve juvenile and adult steelhead migratory passage and survival in the Federal Columbia River Power System.
  • Hatcheries: Improve hatchery management to minimize impacts of hatchery fish on naturally produced steelhead. Supplement natural production where appropriate.
  • Predation: Reduce predation on steelhead in the Columbia River and estuary.
  • Harvest: Maintain low-impact fisheries, increase harvest of hatchery strays.
  • Coordination: Coordinate research and planning within the range of the Middle Columbia River steelhead.
