construction of, the chosen alternative.</DELETED>
<DELETED>    (c) Feasibility Study Deadline.--The Secretary shall

SECTION 1. GLEN CANYON DAM FEASIBILITY STUDY.

    (a) In General.--The Secretary of the Interior (acting through the 
Commissioner of Reclamation) (referred to in this section as the 
``Secretary''), in consultation with the Secretary of Energy, the 
Director of the United States Fish and Wildlife Service, the Director 
of the United States Geological Survey, the Colorado River Basin 
States, and Colorado River Storage Project power contractors, shall 
carry out a feasibility study (including all hydrological modeling) to 
analyze alternatives (including infrastructure upgrades) to address 
downstream invasive species at Glen Canyon Dam.
    (b) Included Alternatives.--The alternatives analyzed under 
subsection (a) may include a thermal curtain or a selective water 
withdrawal system at Glen Canyon Dam to optimize hydropower generation 
when releasing cold water from Glen Canyon Dam, while also preventing 
entrainment of invasive species, pursuant to the 2016 Long-Term 
Experimental and Management Plan Supplemental Environmental Impact 
Statement and Record of Decision and section 1802 of the Grand Canyon 
Protection Act of 1992 (Public Law 102-575; 106 Stat. 4669).
    (c) Feasibility Determination.--If the Secretary determines that an 
alternative studied under subsection (a) is feasible under the 
reclamation laws, the Secretary may initiate design, construction, and 
associated activities of, as applicable, the recommended alternative, 
including any necessary policy actions allowable under the reclamation 
laws.
    (d) Feasibility Report.--After completion of the feasibility study 
required under subsection (a), the Secretary shall develop a summarized 
feasibility study report that includes, at a minimum--
            (1) an analysis of the alternatives analyzed and 
        identification of the recommended alternative;
            (2) an allocation of the construction, operation, 
        maintenance, and replacement costs of the recommended 
        alternative to the authorized purposes of the Colorado River 
        Storage Project;
            (3) the major structural features and nonstructural 
        features of the recommended alternative, any special 
        considerations for implementation of the recommended 
        alternative, and the estimated cost of implementation of the 
        recommended alternative;
            (4) an analysis of the effects of the recommended 
        alternative on hydropower production and rates, which shall be 
        developed in consultation with the Western Area Power 
        Administration;
            (5) a recommendation of the Secretary on whether--
                    (A) the recommended alternative is found to be 
                technically and financially feasible in accordance with 
                the reclamation laws; and
                    (B) the recommended alternative should be

        subsection (d), submit to the Committee on Energy and Natural 
        Resources of the Senate and the Committee on Natural Resources 
        of the House of Representatives the feasibility report required 
        under that subsection.
    (f) Funding.--
            (1) In general.--The costs of the feasibility study 
        required under subsection (a) shall be paid for by the 
        Secretary using appropriated funds.
