The USGS has published a new Fact Sheet, “Science Partnership between U.S. Geological Survey and the Lower Elwha Klallam Tribe: Understanding the Elwha River Dam Removal Project.”
Two large hydroelectric dams on the Elwha River in Washington State were removed in the period 2011–2014 to restore the river ecosystem and recover imperiled salmon populations. The new fact sheet summarizes findings by a multidisciplinary team of scientists from the Lower Elwha Klallam Tribe, the USGS, other agencies, universities, and non-governmental organizations who collected data before, during, and after dam removal. The 4-page fact sheet lists key lessons, details some impacts of dam removal on river sedimentation and the physical and biological makeup of the estuary and coast, and lists references with in-depth information.
