Directs the Secretary to continue operation of the Glines Canyon dam after the Elwha dam has been removed, subject to appropriations.

Requires the Secretary to: (1) complete a Glines Canyon engineering and design study concerning the reconfiguration of transmission lines and dam operational controls; and (2) evaluate the impact that managing such Project for fisheries restoration will have on future hydropower operations.

Directs the Secretary to: (1) develop an annual work plan that defines all requirements necessary to achieve the ecosystem restoration objectives of the Act; and (2) appoint an Independent Scientific Review Panel to review progress toward restoration of the Elwha River ecosystem and the contribution of removal of the dam toward restoration.
