DWR and Reclamation (owners and operators of the State Water Project and Central Valley Project, respectively (collectively Projects)), through their TUCPs have requested changes to water right requirements  included in State Water Board Decision 1641 (D-1641) to allow management of reservoir releases on a pattern that conserves upstream storage for fish and wildlife protection and Delta salinity control while providing critical water supply needs.
