Chemung Canal Chemung Canal The Chemung Canal is a former canal in New York, United States. The canal connected Seneca Lake at Watkins Glen to the Chemung River at Elmira, New York. It was planned to connect the Finger Lakes region and Pennsylvania's Susquehanna River watershed with New York's Erie Canal system. The latter connected the Great Lakes with the Hudson River and ultimately the Atlantic port of New York City. The state government allocated $300,000 for the construction, which started in 1830 and was completed in 1833. Opening to full service was delayed because of damage from a rainstorm in May
Great Lakes Waterway lake freighters to travel from the system's saltwater outlet to its far interior. The Waterway has larger locks and deeper drafts than the lower Seaway, limiting large freighters to the four lakes upstream of the Welland Canal and Lake Ontario and similarly restricting passage beyond the canal by larger ocean vessels. The two waterways are often jointly and simply referred to as the "St. Lawrence Seaway", since the Great Lakes, together with the St. Lawrence River, comprise a single navigable body of freshwater linking the Atlantic Ocean to the continental interior. Shipping channels separate upbound traffic from downbound traffic. The
