"Massive Salmon Die-Off in California River After Release of 830,000 Fry"

Around 830,000 salmon fry released into California's Klamath River are believed to have died due to gas bubble disease caused by a severe change in pressure as they went through the Iron Gate Dam tunnel. The fish were the first release from the Fall Creek Fish Hatchery, part of a project to support salmon populations once the river is fully undammed. The dam and tunnel are set to be removed later this year. The incident is a stark reminder of the harm caused by dams to salmon runs in the Klamath River.
