        ``Apalachicola-Chattahoochee-Flint projects'' means the Federal 
        water resources projects on the Apalachicola, Chattahoochee, 
        and Flint Rivers in the States of Alabama, Florida, and Georgia 
        authorized by section 2 of the Act of March 2, 1945 (59 Stat. 
        17, chapter 19; 60 Stat. 635, chapter 595) and section 203 of

                    (E) Jim Woodruff Dam and Reservoir.
            (2) Freshwater flows.--The term ``freshwater flows'' means 
        the quality, quantity, timing, and variability of freshwater 
        flows required--
                    (A) to support and reestablish--
                            (i) the physical, chemical, biological, and 
                        overall ecological integrity of the components, 
                        functions, and natural processes required for a 
                        thriving and resilient Chattahoochee River, 
                        Apalachicola River, Apalachicola River 
                        floodplain, and Apalachicola Bay;

                        composition, diversity, adaptability, and 
                        functional organization similar to those found 
                        in the Chattahoochee River and Apalachicola 
                        River ecosystems prior to construction of the 
                        Apalachicola-Chattahoochee-Flint projects;
                    (B) to restore and recover species that are 
                endangered, threatened, or at risk; and
                    (C) to prevent significantly harmful adverse 
                impacts to the Chattahoochee River and Apalachicola 
                River ecosystems.
    (b) Project Modification.--Notwithstanding any authorized purpose 
of the Apalachicola-Chattahoochee-Flint projects, the Secretary shall 
operate the Apalachicola-Chattahoochee-Flint projects in a manner that 
ensures the maintenance of freshwater flows.
    (c) Revision of Water Control Manuals.--
            (1) In general.--Not later than 18 months after the date of 
        enactment of this Act, the Secretary shall complete the ongoing 
        revision of the water control manuals for the Apalachicola-
        Chattahoochee-Flint projects and issue revised water control 
        manuals for those projects that ensure the maintenance of 
        freshwater flows.
            (2) Operational modifications.--In carrying out paragraph 
        (1), the Secretary shall ensure that operational modifications 
        needed to maintain freshwater flows are achieved, to the 
        maximum extent practicable, while providing system-wide balance 
        in conservation storage through the maintenance of water levels 
        within the same action zone for each of the Apalachicola-
        Chattahoochee-Flint project reservoirs.
            (3) Independent peer review of water control manuals.--
                    (A) In general.--The Secretary shall enter into an 
                arrangement with the National Academy of Sciences under 
                which the National Academy of Sciences shall carry out 
                an independent peer review of each revised water 
                control manual, as required under section 2034 of the 
                Water Resources Development Act of 2007 (33 U.S.C. 
                2343).
                    (B) Compliance.--Each independent peer review under

                Water Resources Development Act of 2007 (33 U.S.C. 
                2343).
            (4) Final approval.--Before a final water control manual 
        may be issued, the Secretary shall obtain written approval of 
        each water control manual developed under this subsection 
        from--
                    (A) the Administrator of the Environmental 
                Protection Agency;

Summary: Directs the Department of the Army to operate the Apalachicola-Chattahoochee-Flint federal water resources projects on the Apalachicola, Chattahoochee, and Flint Rivers in Alabama, Florida, and Georgia in a manner that ensures the maintenance of freshwater flows. Defines freshwater flows to mean the quality, quantity, timing, and variability of freshwater flows required to: (1) support and reestablish the ecological integrity of the rivers, commercial and recreational fisheries dependent on freshwater flows into Apalachicola Bay and adjacent waters, and thriving and diverse fish, wildlife, and plant populations having species composition, diversity, adaptability, and functional organization similar to those found prior to construction of the Apalachicola-Chattahoochee-Flint projects. (2) restore and recover species that are endangered, threatened, or at risk. And (3) prevent significantly harmful adverse impacts to the Chattahoochee and Apalachicola River ecosystems. Requires the Army to: (1) complete the ongoing revision of the water control manuals for such projects and issue revised manuals that ensure the maintenance of freshwater flows. (2) ensure that operational modifications needed to maintain freshwater flows are achieved while providing system-wide balance in conservation storage through the maintenance of water levels within the same action zone for each of the project reservoirs. (3) enter into an arrangement for the National Academy of Sciences to carry out an independent peer review of each revised manual. And (4) obtain written approval from the Environmental Protection Agency, the US Fish and Wildlife Service, the National Oceanic and Atmospheric Administration, and the US Geological Survey of each manual developed before a final manual may be issued.
