The Seneca River is a large waterway that begins at the outflow of Seneca Lake in Seneca County and flows eastward for approximately 61 miles to Three-Rivers in Onondaga County, where it combines with the Oneida and Oswego Rivers. The Oswego River then continues north into Lake Ontario. The Seneca River is part of the New York State Canal System, including portions of the Barge Canal, Erie Canal, and Cayuga-Seneca Canal. Known for its picturesque landscapes and rich ecosystem, the river meanders through the beautiful Finger Lakes region, offering anglers a diverse fishing experience with its abundance of fish species and minimal fishing pressure. With its slow current and ample underwater structure, the Seneca River has become increasingly popular among tournament anglers while still maintaining relatively uncrowded conditions.
