This marsh was once dammed up to serve as a boat basin on the adjoining C & O Canal, and it was called Poly Ponds. Boat basins were used sort of like a "railroad yard" for canal boats, i.e. they were used as places where canal boats were loaded and unloaded, stored and repaired. It has been reclaimed by nature since the maintenance of the Canal ended about 1924.
