Operations Overview • Purpose • In-Delta Storage as a component of the State and Federal System (Public Ownership) • Meet Delta Standards • Additional benefits for environmental purposes (EWA, CVPIA, ERP) • No impact on drinking water quality • Overall system operational flexibility
Operational Concept • Previous reverse flow operation changed with DFG Review • Fish Screen and other controls isolated with a transition pool • Fish Screen gravity flow isolated from pumping units • Reservoir supply and discharge at different levels • Three interchangeable stages; forebay, midbay; afterbay for flow transfer • Gravity inflows and outflows optimized with gated structures and pumping combinations • Required flow possible with smaller head differences
