hatcheries in the continental United States, producing tens of millions of salmonids annually, supporting an economically important sport fishery. RBFWO, CNFH, US Bureau of Reclamation (BOR) and California Department of Fish and Wildlife have been working collaboratively on a multi-benefit water infrastructure improvement program. Part of that program focuses on establishing a population of endangered winter-run Chinook Salmon into Battle Creek, so they have a secondary population outside the Sacramento River. CNFH has been chosen as a prime site for us to raise these fish in addition to its sport fishing production goals, but currently the water intake system does not meet specific standards and are under an aged infrastructure review being led by BOR. Under this review a new water intake system is to be added along with updating older water intake structures. The analysis and model to be generated by this agreement would directly assist BOR with creating designs for updating this water intake and overall help CNFH meet their production goals. Required deliverables include a complete and comprehensive assessment for the future design team.
