The New York State Canal System is a successor to the Erie Canal and other canals within New York. Currently, the 525-mile system is composed of the Erie Canal, the Oswego Canal, the Cayuga–Seneca Canal, and the Champlain Canal. In 2014 the system was listed as a national historic district on the National Register of Historic Places in its entirety, and in 2016 it was designated a National Historic Landmark.
The Erie Canal connects the Hudson River to Lake Erie; the Cayuga–Seneca Canal connects Seneca Lake and Cayuga Lake to the Erie Canal; the Oswego Canal connects the Erie Canal to Lake Ontario; and the Champlain Canal connects the Hudson River to Lake Champlain.
