The Secretary can add new or extra parts to a project to get more benefits, such as more conservation storage, if she finds those benefits are needed, feasible, and fit the project's purposes. Even if section 507 would limit it, this can happen with section 506 work only after a feasibility study and a cost-share agreement with Federal and non‑Federal funders; the costs must be borne only by the beneficiaries and repaid under Federal Reclamation law (Act of June 17, 1902, 43 U.S.C. 371 et seq.).
