Iron Gate Dam was an earthfill hydroelectric dam on the Klamath River in northern California, outside Hornbrook, California, that opened in 1964. The dam blocked the Klamath River to create the Iron Gate Lake Reservoir. From Wikipedia
The removal of dams on the Klamath River, aimed at restoring natural ecosystems, has led to the unexpected death of over 800,000 Chinook salmon due to gas bubble disease.
