| Notes | 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. (from the Abstract) "Open-file report." |
