Erie Canal Since the 1990s, the canal system has been used primarily by recreational traffic, although a small but growing amount of cargo traffic still uses it.
Chesapeake and Ohio Canal The Chesapeake and Ohio Canal, abbreviated as the C&O Canal and occasionally called the "Grand Old Ditch,"[1] operated from 1831 until 1924 along the Potomac River from Washington, D.C., to Cumberland, Maryland. The canal's principal cargo was coal from the Allegheny Mountains.
