Goose Creek & Little River Navigation, Double Lock, Mouth of Goose Creek at Potomac River, Leesburg, Loudoun County, Virginia

Significance: The double lock at Clapham's Mill is the most important structure on the Goose Creek and Little River Navigation, a 20-mile river improvement project chartered in 1832 and dissolved in 1857. The purpose of the navigation was to provide lock-and-dam, or slackwater, navigation to connect landlocked portions of Loudon, Fauquier, and Prince William counties in Virginia with the Chesapeake and Ohio Canal on the eastern bank of the Potomac River in Maryland. Of the nine locks, four canal sections and four dams constructed as part of this improvement, Clapham's Double Lock is the best preserved and one of the most significant canal structures in the Commonwealth of Virginia.
