Young Salmon Survival High Through Snake River Dams

Of the 13 salmon and steelhead stocks in the Columbia Basin listed under the Endangered Species Act, only four migrate through the lower Snake River dams. Survival through these dams for young salmon heading downstream to the ocean is high, with a survival rate of 97 percent, on average. Juvenile steelhead survival is even better, averaging 99.5 percent through the dams.
