The contributing watershed downstream of Chatfield Dam <br />will continue to urbanize and contribute less sediment. Secondly, the <br />reach between the dam and the USACE channel at Columbine Valley will be <br />stabilized as part of the development of the Littleton floodplain park and <br />efforts of the Urban Drainage and Flood Control District. <br /> <br />At present (1987) the sediment load at Union Avenue is low. It represents <br />the flushing of loose residual material from the new USACE channel, <br />continued erosion from the Littleton floodplain park, and minor sediment <br />inflow from the tributary basin downstream of Chatfield Reservoir. <br /> <br />Once the new USACE channel settles into its stable regime, <br />load at Union Avenue should experience a marked decrease. <br />stabilization of the upstream reach, the sediment load <br />decrease. <br /> <br />the sediment <br />Later, with <br />will further <br /> <br />The South Platte River between Chatfield and Union Avenue transports less <br />sediment than would a normal river of its flow character.
