Abstract: The U. S. Department of Interior, Bureau of Reclamation is involved in many dam decommissioning projects in the Western United States. These projects involve complete to partial dam removal. A primary factor of each project is to identify the characteristics and volume of sediment impounded by the dam and to describe the potential erosion and transport of that sediment into the downstream river channel as a result of dam decommissioning. Three Bureau of Reclamation dam decommissioning projects are: 1.) Savage Rapids Dam on the Rogue River in Oregon, 2.) Matilija Dam on the Ventura River near Ventura, California, and 3).Coleman and South Diversion Dams on Battle Creek in California. The dam decommissioning studies for each project are described and sediment characterization before and after dam removal are compared. Insights into the unique characteristics of each project are also given. Conclusions will be drawn about the dam removal projects.
