MISSOURI RIVER.

SEC. 1179. MISSOURI RIVER. (a) Reservoir Sediment Management.— (1) Definition of sediment management plan.—In this subsection, the term “sediment management plan” means a plan for preventing sediment from reducing water storage capacity at a reservoir and increasing water storage capacity through sediment removal at a reservoir. (2) Upper missouri river basin pilot program.—The Secretary shall carry out a pilot program for the development and implementation of sediment management plans for reservoirs owned and operated by the Secretary in the Upper Missouri River Basin, on request by project beneficiaries. (3) Plan elements.—A sediment management plan under paragraph (2) shall— (A) provide opportunities for project beneficiaries and other stakeholders to participate in sediment management decisions; (B) evaluate the volume of sediment in a reservoir and impacts on project purposes, including storage capacity; (C) identify sediment management options, including sediment dikes and dredging; (D) identify constraints; (E) assess technical feasibility, economic justification, and environmental impacts; (F) identify beneficial uses for sediment; and (G) to the maximum extent practicable, use, develop, and demonstrate innovative, cost-saving technologies, including structural and nonstructural technologies and designs, to manage sediment. (4) Justification.—In determining the economic justification of a sediment management plan under paragraph (2), the Secretary shall— (A) measure and include flooding, erosion, and accretion damages both upstream and downstream of the reservoir that are likely to occur as a result of sediment management within the reservoir compared to the damages that are likely to occur if the sediment management plan is not implemented; and (B) include lifecycle costs and a 100-year period of analysis. (5) Implementation.—As part of a sediment management plan under paragraph (2), and in accordance with paragraph (10), the Secretary may carry out sediment removal activities at reservoirs owned and operated by the Secretary in the Upper Missouri River Basin, or at reservoirs for which the Secretary has flood control responsibilities under section 7 of the Act of December 22, 1944 (33 U.S.C. 709), in the Upper Missouri River Basin, in accordance with section 602 of the Water Resources Development Act of 1986 (100 Stat. 4148; 110 Stat. 3758; 113 Stat. 295; 121 Stat. 1076) as if those reservoirs were listed in subsection (a) of that section. (6) Prioritization of sediment management plans.—In carrying out the pilot project under this subsection, the Secretary shall give priority to developing and implementing sediment management plans that affect reservoirs that cross State lines. (7) Cost Share.—The beneficiaries requesting a sediment management plan shall share in the cost of development and implementation of the plan and such cost shall be allocated among the beneficiaries in accordance with the benefits to be received. (8) Contributed funds.—The Secretary may accept funds from non-Federal interests and other Federal agencies to develop and implement a sediment management plan under this subsection. (9) Guidance.—The Secretary shall use the knowledge gained through the development and implementation of sediment management plans under paragraph (2) to develop guidance for sediment management at other reservoirs. (10) Partnership with secretary of the interior.— (A) In general.—The Secretary shall carry out the pilot program established under this subsection in partnership with the Secretary of the Interior, and the program shall apply to reservoirs managed or owned by the Bureau of Reclamation. (B) Memorandum of agreement.—For sediment management plans that apply to a reservoir managed or owned by the Bureau of Reclamation under subparagraph (A), the Secretary and the Secretary of the Interior shall execute a memorandum of agreement establishing the framework for a partnership and the terms and conditions for sharing expertise and resources. (C) Payments.—The Secretary is authorized to accept and expend funds from the Secretary of the Interior to complete any work under this paragraph at a reservoir managed or owned by the Bureau of Reclamation. (D) Lead Agency.—The Secretary that has primary jurisdiction over a reservoir shall take the lead in developing and implementing a sediment management plan for that reservoir. (11) Other authorities not affected.—Nothing in this subsection affects sediment management or the share of costs paid by Federal and non-Federal interests relating to sediment management under any other provision of law (including regulations). (b) Snowpack and Drought Monitoring.—Section 4003(a) of the Water Resources Reform and Development Act of 2014 (Public Law 113-121; 128 Stat. 1310) is amended by adding at the end the following: “(5) Lead Agency.—The Corps of Engineers shall be the lead agency for carrying out and coordinating the activities described in paragraph (1).” .
