 | The Elwha is a short, steep river, tumbling 45 miles from the mountainous heart of Olympic National Park down to the Strait of Juan de Fuca. |
| The Elwha Report, submitted by the Secretary of the Interior, determined that removing the dams was feasible and necessary to fully restore the fisheries and ecosystem. |
| The restored, free-flowing river is estimated to produce approximately 390,000 salmon and steelhead in about 30 years, compared with less than 50,000 fish if the dams were fitted with upstream and downstream fish passage facilities. |

| Objective(s) - A 3-year intensive study of sediment transport in the Elwha River is proposed to assess the increase in suspended-sediment concentrations during dam removal and resulting changes in the particle-size distribution of bed material. |
| In order to manage the Elwha River during the process of restoration and evaluate the eventual success of the restoration effort, it is important to evaluate its present ecological status. |
| The adjacent Dungeness River basin is a free-flowing system with remaining runs of salmon and serves as a reference basin for comparison with the Elwha River. |
