NOE - Notice of Exemption
The Cordelia Forebay is part of the North Bay Aqueduct (NBA), and acta as a sediment settling basin prior to water being pumped westward from the Cordelia Pumping Plant. The Cordelia Forebay is an asphaltic concrete lined reservoir approximately 130 to 160 feet wide by 340 feet long. The water pumped from the NBA intake at Barker Slough typically has sediment that is fine grained therefore sediment accumulates in the Cordelia Forebay as a layer of mud or slurry on the invert of the forebay.
