                                                         Dear Reader,

                                                         After seven years of discussion, collaboration, research, independent review, and informal public
                                                         scrutiny, the Bay Delta Conservation Plan has been released for formal public review and comment.
                                                         This document, titled Highlights of the BDCP, gives an overview of the legal basis for the plan and
                                                         its central elements, which intend to meet the co-equal goals of ecosystem restoration and water
                                                         supply reliability, as mandated by the 2009 Delta Reform Act. This document is based on technical
                                                         information and is not intended to substitute for the 9,000 pages of material in the actual plan,
                                                         available at www.BayDeltaConservationPlan.com.

                                                         Few parts of California are disconnected from the Sacramento-San Joaquin Delta. Nearly half of
                                                         California’s land surface drains to the Delta, while water drawn from this low-lying estuary sustains
                                                         cities and farms from San Jose to San Diego.

                                                         The historic abundance and diversity of the region’s wildlife was legendary, from massive sturgeon
                                                         to thick flocks of waterfowl. Several Delta species are now listed under state and federal laws to
                                                         prevent extinction, and they have come to symbolize the estuary’s compromised ecology.

                                                         California has struggled for several decades to balance competing demands for the Delta’s
                                                         resources. The Bay Delta Conservation Plan offers a comprehensive, long-lasting, adaptive
                                                         approach to both restore ecological functions and improve water supply reliability.

                                                         The plan details 22 separate conservation measures intended to reverse the decline of the Delta’s
                                                         native fish, plant and wildlife species. The plan identifies changes to the Delta water delivery
                                                         system that would both reduce harm to fisheries and protect against risks posed by the failure of

    Conservation Plan.                                   public are encouraged to review and comment on the plan and its potential impacts.

                                                         At stake are California’s natural heritage and economic prosperity. The Bay Delta Conservation Plan
                                                         reflects the widespread recognition that we cannot stabilize water deliveries from the Delta without
                                                         reversing recent ecological trends. It also reflects the general agreement that the current situation
                                                         in the Delta is unsustainable, and we must act now for the sake of future generations.

                                               rivers converge in the Delta—the largest estuary on the west coast.
                                               The Delta of today is made up of dozens of islands and channels,
                                               and more than 1,000 of miles of levees. Not only is the Delta

        central water supply, recover a natural treasure, and deal wisely with future challenges.                Align Water Operations to Better Reflect Natural Seasonal                 Reconnect Floodplains to improve the production of important

        Improving the Delta Ecosystem
                                                                                                                 Delta equipped with state-of-the-art fish screens, thus reducing          habitat.

        new tidal habitat, return riverbanks to a more natural state, and boost food supplies for fish.          threats of sea level rise and earthquakes.                                Return Riverbanks to a More Natural State through the

        The BDCP would help California cope with changing weather patterns by enabling the capture of large
        amounts of winter flood flow at times of minimal ecological risk. A more reliable facility for moving
        water through the Delta would also boost operational flexibility to enhance the state’s ability to
        respond to drought.

        Securing More Reliable Water Supplies
        The BDCP would retrofit, modernize, and add greater flexibility to the state’s water
        system. The proposed BDCP puts more tools to work that would restore water
        supply reliability, securing supplies for Californians. The proposed project also
        reduces exposure to possible system interruption caused by the potential
        failure of aging levees and seismic events. Additionally, the BDCP could
        reduce regulation as ecosystem restoration is realized.

        2
             In some cases, take alternatives also increase or reduce benefits to some covered species. For example, Take Alternative G reduces
             benefits to covered fish due to less tidal natural community restoration. Take Alternative H increases benefits to some covered fish
             due to more restoration of several aquatic natural communities, but increases take on some covered terrestrial species.
