In the 1820s the Oswego Canal opened, linking the Erie Canal and Lake Ontario and boosting Fulton's economy. Locks enabled boats to negotiate the falls of the Oswego River, which drop 14 feet, and a series of rapids to the north, which drop another 30 feet. An observation area in Canal Park overlooks the lower locks.
Exhibits related to Fulton's history can be seen at the Pratt House, 177 S. First St.; phone (315) 598-4616.
