Catalog Record

Elwha River Sediment Monitoring Data from the Elwha Bed Load Monitoring Database

The data contained in the files are continuous bed load flux. The data are summed across the cross section and averaged over an hour. Data were collected with a calibrated surrogate sediment measurement system including 72 impact plates, mounted adjacent to each other, spanning the cross section of the Elwha River at river kilometer 5 (river mile 3.1). The following Science and Technology project numbers apply to the Elwha bed load data; 0115, 1709, 6209, 4542, 9562, and 6499.

Location Information

Location Name Elwha River
Location Description The Elwha River is a 45-mile (72 km) river on the Olympic Peninsula in the U.S. state of Washington. From its source at Elwha snowfinger in the Olympic Mountains, it flows generally north to the Strait of Juan de Fuca. Most of the river's course is within the Olympic National Park. From 1911 to 2014, dams blocked fish passage on the lower Elwha River. The National Park Service removed the two dams as part of the Elwha Ecosystem Restoration Project. Dam removal work began in September 2011 and was completed in August 2014.
