Scope/Content: Abstract: The removal of the Elwha and Glines Canyon dams is the only alternative that would result in the "full restoration of the Elwha River ecosystem and native anadromous fisheries" as prescribed by the Elwha River Ecosystem and Fisheries Restoration Act (section 3(c)). A synopsis of the consequences of each restoration alternative is provided in Table 3. Retention of either or both dams, even with the provision of fish passage facilities and other measures, would not allow for the full restoration of native anadromous fisheries , in particular chinook, pink, and chum salmon. Additionally, retention of either or both dams would prevent the restoration of natural sediment transport processes, resulting in continued degradation of the river below the dams, the estuary, and near coastal areas. Retention of either or both reservoirs would prevent the restoration of important bottom land and riverine habitat for wildlife and anadromous fish, as well as prevent full nutrient transport, thus impacting freshwater organisms.
