Increased spill at dams has commonly brought dissolved gas supersaturation higher than levels established by state and federal water quality criteria in the Columbia and Snake Rivers. These increased spill volumes are intended to provide safe passage for migrating juvenile salmon. However, dissolved gas supersaturation resulting from spill in.

Salmon on the Snake River Essential to Orca whales and more. The Columbia and Snake Rivers were once the greatest salmon rivers in the world until four dams were built on the lower Snake River. Wild salmon bring nutrients from the briny ocean back to the high mountain streams.

A lawful federal salmon plan must restore a freely flowing lower Snake River by removing its four costly dams and increase water releases or ‘spill’ over the dams that remain. Ina federal judge rejected the federal dam agencies’ latest plan for protecting Columbia-Snake River salmon.

Read more about juvenile Snake River steelhead and chinook survival through the hydrosystem here.
