Jeff Duda, USGS research ecologist, has been studying the effects of dam removal in the Pacific Northwest, such as on the Elwha River. He is in New Brunswick this week to give lectures on the process of dam removal and its ecological impacts, a topic very much front-of-mind as a result of the pending Mactaquac decision. He is also on the Science Advisory Board for the Mactaquac Aquatic Ecosystem Study (MAES) being undertaken by Canadian Rivers Institute. Duda was interviewed on CBC about his planned talks on March 22 and 23. We have a long list of dam removal videos, collected by Larissa Holman for the Energy Transitions team during her summer internship with the project in 2014. Some of these were from the Elwha River, showing the dam removal, with time-series photography, changing sediments in former lakebeds, salmon coming immediately back, and the impact on sandbars at the river’s mouth.
