Coyote Valley Dam flood release, Jan 16, 2023, by Kenneth James (DWR)

FIRO is a flexible water management approach that uses data from watershed monitoring and improved weather forecasting to help water managers selectively retain or release water from reservoirs for increased resilience to droughts and floods. FIRO applies emerging science and technology to optimize water resources and adapt to climate change without costly infrastructure. The goal of FIRO at Lake Mendocino is to update the 1950s-era Water Control Manual by applying forecasting advancements to increase water supply reliability without reducing - and while possibly enhancing - the existing flood protection capacity of Lake Mendocino and downstream flows for fish habitat.
