Median suspended-sediment concentrations ranged from 24 to 61 milligrams per liter at 7 daily record stations and from 6 to 539 milligrams per liter at 70 partial-record stations. Estimated suspended-sediment yields ranged from 11 to 2,310 tons per square mile per year. Significant trends were found in only 9 of 36 stations with long-term records. At six of the nine stations, suspended-sediment concentrations (adjusted for streamflow) had been decreasing with time.
