Salmon Numbers Still Depressed
This region supports tremendous fish diversity with 74 populations of salmon, steelhead, and bull trout. Just 26 (35 percent) are meeting their minimum recovery abundance goals.
- Most fall Chinook populations remain at a high or very high risk due to low numbers of natural-spawning fish and competition with hatchery fish on spawning grounds. Work is underway to reduce these impacts, but improvements in habitat also are needed.
- Spring Chinook require successful reintroduction efforts upstream of dams.
- Chum populations are also at high to very high risk due to very low abundance, with the exception of Grays River and Columbia River spawners.
- Coho abundance levels generally are below recovery goals. Long-term trends are difficult to assess because of limited data and recent low survival rates in the ocean.
- Steelhead abundance is low, but several winter- and summer-run populations are showing moderate improvements.
