Abstract: An investigation was conducted during the silt runs on the North Platte River to determine the continued effectiveness of the runs in providing fine sediments to the canal systems downstream. A sediment monitoring program was conducted from 1979 through 1981. Changes which had occurred in storage between the 1966 and 1981 surveys were documented. Changes in sediment concentration discharging below the dam while fluctuating the reservoir pool were analyzed to determine optimum conditions for the silt runs. It was concluded that the runs would continue to move sediment downstream to the canal intakes over the next 15 years.
