Sediment yields of streams in the Umpqua River Basin, Oregon

January 1, 1975

This report summarizes sediment data collected at 11 sites in the Umpqua River basin from 1956 to 1973 and updates a report by C. A. Onions (1969) of estimated sediment yields in the basin from 1956-67.  Onions' report points out that the suspended-sediment data, collected during the 1956-67 period, were insufficient to compute reliable sediment yields.  Therefore, the U.S, Geological Survey, in cooperation with Douglas County, collected additional data from 1969 to 1973 to improve the water discharge-sediment discharge relationships at these sites.  These data are published in "Water resources data for Oregon, Part 2, Water quality records," 1970 through 1973 water years.  In addition to the 10 original sites, data were collected during this period from the Umpqua River near Elkton station, and a summary of the data for that station is included in table 1.
