Investigations Upstream of Chief Joseph and Grand Coulee Dams

In May 2019, the UCUT completed Phase 1 of our phased approach to Fish Passage and Reintroduction into the U.S. and Canadian Upper Columbia Basin.

The Phase I Report confirms the reintroduction of salmon to the U.S. portion of the upper Columbia River upstream of Chief Joseph Dam is likely to achieve identified tribal goals given the following:

  • Current dam operations
  • Existing riverine and reservoir habitat conditions
  • Donor stock availability and risks to resident fish species
  • The likely effectiveness of state-of-the-art juvenile and adult passage technologies that could be built at both Chief Joseph Dam and Grand Coulee Dam.

Results from the investigations have shown that reintroduction is viable for the species evaluated.

"The Willamette River, a major tributary of the Columbia River that flows between Portland and Eugene, Oregon, is cited in this year's list for outdated dam operations that pose threats to water quality and the river’s imperiled salmon and steelhead runs."
