Summary

Two large dams were removed from the Elwha River in Washington, starting in 2011 and ending in 2014. The Elwha and the Glines Canyon dams were located approximately 7 km and 20 km upstream, respectively, from the Elwha River's mouth on the Strait of Juan de Fuca. The dams trapped over 20 million cubic meters of sediment. Dam removal changed the river's sediment budget and water flow, which affected the river's morphology. This data release presents digital elevation models (DEMs), orthomosaic images, dam height measurements, sediment measurements and river streamgage data that were collected by the U.S. Geological Survey (USGS) and U.S. Bureau of Reclamation (USBR) to support studies on morphodynamic and sediment budget responses of [...]
