The Seneca River flows 61.6 miles (99.1 km) through the Finger Lakes region of Upstate New York in the United States. The main tributary of the Oswego River – the second largest river flowing into Lake Ontario – the Seneca drains 3,468 square miles (8,980 km2) in parts of fourteen New York counties. The Seneca flows generally east, and is wide and deep with a gentle gradient. Much of the river has been channelized to form part of the Erie Canal.
The Seneca River begins at Geneva in Seneca County, as the outflow of Seneca Lake, flowing east past Waterloo and Seneca Falls. Skirting the northern end of Cayuga Lake at the Montezuma Marsh, it turns north, receiving the Clyde River from the west, forming the Seneca–Cayuga county line, then the border of Cayuga and Wayne counties. The river passes under Interstate 90, flowing northeast past Weedsport, across the middle of Cayuga County into Cross Lake.
Below Cross Lake the Seneca River enters Onondaga County. It turns sharply north then east, past Baldwinsville and Liverpool, along the northern edge of metro Syracuse where it receives the outflow of Onondaga Lake. The river then flows north to join the Oneida River at Three Rivers on the Onondaga–Oswego County line, forming the Oswego River. From the confluence, the Oswego flows a further 23 miles (37 km) north, emptying into Lake Ontario at the city of Oswego.
