In July, the Bureau of Reclamation and U.S. Fish & Wildlife Service installed several temporary water chilling units at Livingston Stone National Fish Hatchery to protect winter-run Chinook salmon in a crucial year of their life cycle. As California is experiencing a third consecutive drought year, this measure was implemented to cool and stabilize the water supply to the hatchery as elevated water temperatures were expected at Shasta Lake due to low lake levels. Poor survival during the last two drought years makes this a critical year for the population’s survival. With the help of these chillers, the hatchery will continue to provide a critical safety net for winter-run Chinook salmon while in-river conditions remain poor. Technicians are on site monitoring the chilling units 24-hours a day in order to ensure success.
