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. 1. Apalachicola, Chattahoochee, and Flint River projects (a) Definitions In this section: (1) Apalachicola-Chattahoochee-Flint projects The term Apalachicola-Chattahoochee-Flint projects (A) Buford Dam and Reservoir; (B) West Point Dam and Reservoir; (C) George W. Andrews Dam and Reservoir; (D) Walter F. George Dam and Reservoir; and (E) Jim Woodruff Dam and Reservoir. (2) Freshwater Flows The term freshwater flows (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 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 this paragraph shall comply with section 2034 of the 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; (B) the Director of the United States Fish and Wildlife Service; (C) the Director of the National Oceanic and Atmospheric Administration; and (D) the Director of the United States Geological Survey. (d) Applicability of other Federal and State laws Except as provided in subsection (b), nothing in this section waives, limits, or otherwise affects the applicability of any provision of Federal or State law that would otherwise apply to the Apalachicola-Chattahoochee-Flint projects.

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.
