Summary

Despite section 507, the Secretary may add benefits to a project by building new or supplementary works if she finds the added benefits, such as more conservation storage, are needed, in the U.S. and project interest, feasible, and consistent with the subchapter, and if the feasibility study sets conditions. Federal and nonfederal funders must reach a cost-share agreement; costs must be borne by beneficiaries and repaid under Federal Reclamation law (Act of June 17, 1902, 43 U.S.C. 371 et seq.) and related acts.
