Extreme heat will soon kill nearly all salmon in Sacramento River, officials say
California officials are warning nearly all juvenile chinook salmon in the Sacramento River could die due to abnormally hot underwater conditions as heat waves continue to bake the West. There could be a “near-complete loss” of the young endangered species of salmon because temperatures above 100 degrees for extended periods of time are overheating the river, making it uninhabitable for the fish to grow beyond their egg stage, the California Department of Fish and Wildlife (CDFW) confirmed to CNN on Tuesday.
