WFRC Scientist Discusses an Undammed Elwha River in Voice of America Series
Our science assessing the recovery of the Elwha River following dam removal was recently featured on Voice of America.
WFRC’s Research Ecologist Jeffery Duda was recently featured in a video series about the Elwha dam removals and river restoration. The video is part of a Voice of America series exploring various aspects and implications of Klamath dam removal. Episode four of the series "Promising Signs of Recovery on Undammed Elwha River" features an interview with Jeff about his research and findings with collaborators following dam removal.
The Elwha River studies conducted since dam removal was completed in 2014 allowed scientists to gain a more in-depth view on dam removal and ecosystem recovery. WFRC has been involved with similar evaluation and monitoring of numerous dam removals across the region as well as national level assessments of the practice. Together with our partners, we are well-prepared to address management questions and decisions moving forward, including proposed dam removals on the Klamath River.

Dam removal in the United States is increasing as a result of structural concerns, sedimentation of reservoirs, and declining riverine ecosystem conditions. The removal of the 32 m Elwha and 64 m Glines Canyon dams from the Elwha River in Washington, U.S.A., was the largest dam removal project in North American history. During the 3 yr of dam removal—from September 2011 to August 2014—more than te
