Ritchie, A.C., Curran, C.A., Magirl, C.S., Bountry, J.A., Hilldale, R.C., Randle, T.J., and Duda, J.J., 2018, Data in support of 5-year sediment budget and morphodynamic analysis of Elwha River following dam removals: U.S. Geological Survey data release,


Daily values of discharge and sediment loads were measured and estimated at U.S. Geological Survey gaging station 12046260, on the Elwha River at the diversion near Port Angeles, Washington. Daily data are reported from September 15, 2011 to September 30, 2016. Specific data include (1) date; (2) discharge; (3) suspended-sediment concentration and one standard-deviation bounds; (4) percentage of fine-grained particles (silts and clays) in suspension; (5) loads of total suspended-sediment, fine-grained particles in suspension, and sand in suspension; (6) gauged bedload for particles between 2-16 mm and greater than 16 mm; and (7) estimated bedload for particles smaller than 2 mm.

Data were collected to quantify the flux of water, suspended sediment, and bedload sediment at the U.S. Geological Survey gaging station 12046260, Elwha River at Diversion Near Port Angeles, WA. The gaging station 12046260 is downstream of the 2011-2014 dam removal of two large dams on the Elwha River. These discharge and sediment flux data were combined with morphological data collected by collaborative researchers and combined into a total river sediment budget during and after dam removal.
