To direct the Secretary of the Army to provide for modification of certain Federal water resources development projects on the Apalachicola, Chattahoochee, and Flint Rivers, and for other purposes.

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 U.S. Fish and Wildlife Service, the National Oceanic and Atmospheric Administration, and the U.S. Geological Survey of each manual developed before a final manual may be issued.

SECTION 1. APALACHICOLA, CHATTAHOOCHEE, AND FLINT RIVER PROJECTS.

    (a) Definitions.--In this section:
            (1) Apalachicola-Chattahoochee-Flint projects.--The term 
        ``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 
        the Flood Control Act of 1962 (76 Stat. 1182), including--
                    (A) Buford Dam and Reservoir;

                    (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;
                            (ii) commercial and recreational fisheries 
                        dependent on freshwater flows into Apalachicola 
                        Bay and adjacent waters, including the Gulf of 
                        Mexico; and
                            (iii) thriving and diverse fish, wildlife, 
                        and plant populations having species 
                        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
