(AP) - State and federal officials say they're revising their strategy for releasing water from California's largest reservoir for the coming long, hot summer.
Officials said Tuesday that they're trying to prevent a repeated kill-off of salmon migrating up the Sacramento River like last year. Salmon need cool water to be released from Lake Shasta into the Sacramento River, or they will die.
David Murillo of the U.S. Bureau of Reclamation says that holding back some water from Shasta will force them to adjust how much water they will release from other reservoirs.
Officials say the plan is changing because equipment had provided inaccurate temperatures in Lake Shasta.
Chuck Bonham, director of the California Department of Fish and Wildlife, says salmon in the river are resilient, but they face extinction.
