Abstract
After years of anticipation, volumes of Environmental Impact Statements, multiple mitigation projects, and the multidisciplinary collection of predam removal data, the deconstruction phase of the Elwha River restoration officially began on September 17th, 2011. With their simultaneous decommissioning, the removal of the 64 m tall Glines Canyon Dam and the 33 m tall Elwha Dam represents one of the largest such projects of its kind in North America. It’s also an excellent opportunity to study large-scale ecosystem restoration, as the majority of the reconnected habitat that will become available to recolonizing salmon occurs in the protected wilderness areas of Olympic National Park. As part of a week-long series of ‘Celebrate Elwha’ events, which culminated with a moving ceremony commemorating the official launch of dam removal, I was proud to work with a number of dedicated people, listed below, to organize the two day 2011 Elwha River Science Symposium.
Many of the scientists working on the Elwha project have regularly met, since around 2004, for annual meetings. Loosely organized under the auspices of the Elwha Research and Elwha Nearshore consortia, the annual meetings have been informative for many reasons, including the sharing of study plans, field schedules, and preliminary results. It has been a great way for groups of physical scientists and groups of biologists to learn about the questions of interest to each group and to explore areas of overlap. In some cases, these meetings have spawned new collaborations, synergies, and research directions. In planning for the 2011 Elwha River Science Symposium, we sought to retain this espirit de corps, but realized that the start of dam removal heralded an important new phase of the project and called for an event that celebrated this special occasion.
