Seneca Falls, or Rapids, is located about five miles above the Great Falls of the Potomac River. Seneca Falls begins just below the mouth of Seneca Creek, near the Fairfax-Loudoun county line.
As president of the Potomac River Company, GW passed through Seneca Falls on several occasions, especially during inspection trips to investigate the potential for the construction of canals and locks in the area to facilitate navigation on the Potomac River (see Ledger B, 204, 227).
