A unique multiuse diversion facility on the American River near Auburn, California, affords a reliable water supply, ensures adequate base flows to address environmental concerns, facilitates the passage of fish and boats, and provides white-water recreational opportunities. Concluding a process that began more than 40 years ago with the construction of the ill-fated Auburn Dam, the facility brings flows back to a previously dewatered stretch of the channel.
