Which was farther north, Corpus Christi Ship Channel or Cayuga–Seneca Canal?
Cayuga–Seneca Canal The Cayuga–Seneca Canal is a canal in New York, United States. It is now part of the New York State Canal System.
North Shore Channel The North Shore Channel is a drainage canal built between 1907 and 1910 to flush the sewage-filled North Branch of the Chicago River down the Chicago Sanitary and Ship Canal. The sewage carrying duty has been largely taken over by the Chicago Deep Tunnel, but there are still occasional discharges due to heavy rains.
