830,000 fall-run chinook salmon die in Klamath River after release, possibly due to gas bubble disease from water pressure change.

Hundreds of thousands of young fall-run chinook salmon have died in the Klamath River following their release, potentially due to gas bubble disease caused by a change in water pressure. The California Department of Fish and Wildlife (CDFW) released around 830,000 fish into Fall Creek, which feeds into the Klamath River, and they began to die off while passing the Iron Gate Dam's tunnel. The dam is part of a historic removal project to help salmon runs.
