News Release: CDFW Moves to Prevent Fish Loss, Evacuates Fish at American River and Nimbus Hatcheries
From the California Department of Fish and Wildlife (CDFW):
“With extreme drought conditions reducing the cold water supply available, California Department of Fish and Wildlife (CDFW) are moving the last rainbow trout out of the American River Hatchery to avoid future losses of young fish to rising water temperatures. CDFW biologists predict that by mid-summer the temperature of the water entering the hatchery will exceed tolerable temperatures for the growing fish, causing extensive — if not total — loss of all fish in the hatcheries.”
