One of Reston’s most eroded stream channels lies between Wakerobin Lane and Cedar Cove Cluster, just south of South Lakes Drive and downstream of South Lakes High School, Langston Hughes Middle School, and Whisperwood Cluster. The channel, which feeds into Lake Audubon, has been eroding continuously since the initial development on the watershed in the late 1970s and early 1980s. With approximately 50 percent of the 50-acre watershed now covered with impervious surfaces such as roadways, parking lots, rooftops and sidewalks, the stream is in need of stabilization and restoration to prevent further damage to the channel itself, public and private utilities, members’ properties and Lake Audubon.
Over the course of four dredging projects conducted on Lake Audubon, Reston Association has spent approximately $100,000 to remove around 2,000 cubic yards of sediment from the lake cove just below this channel.
