Fluvial-sediment samples have been collected from the Kansas River at Wamego from 1957-70 by the U.S. Geological Survey in cooperation with the Kansas Water Resources Board. During this period. the stream-runoff pattern of the basin has been altered by constructions of Tuttle Creek and Milford Reservoirs.
An analysis of data shows that the reduction of suspended sediment discharge has been significant as a result of reservoir storage. However. the particle-size distribution of fluvial sediment has not been appreciably altered.
