Summary

This data release provides bathymetry and acoustic-backscatter data collected during a 2016 SWATHPlus-M survey offshore the Elwha River mouth, Strait of Juan de Fuca, Washington. Data were collected and processed by the U.S. Geological Survey, Pacific Coastal and Marine Science Center during field activity 2016-605-FA. This survey, along with two other surveys (Cochrane and others, 2008, Finlayson and others, 2011) was conducted to map changes that have occurred following sediment input from dam removals from the Department of the Interior's Elwha River Restoration Project. This project resulted in the removal of two large dams on the Elwha River during 2011-2014, which released millions of tonnes of sediment to the river and coast. Collaborative partners in this work include the Lower Elwha Klallam Tribe.
