Description:

The Turkey Run @ Truro Subdivision Stream Restoration project was substantially completed within budget on October 19, 2017. This project included restoring approximately 3,850 linear feet of stream channel and tributaries. The Tributary of Turkey Run which drains directly to Accotink Creek in the Accotink Creek watershed is located in the center of Fairfax County, Virginia and drains southeast to Accotink Bay, then Gunston Cove and finally to the Tidal Potomac River. Restoration of the stream was achieved through the use of natural channel design principles.
