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.
