The Salmon River, located in Oswego County, stretches 17 miles from the Lighthouse Hill Reservoir in Altmar to where it empties into Lake Ontario at Port Ontario. There are 12 miles of Public Fishing Rights along the river. The Salmon River offers some of the finest sportfishing in the country. Two major fish records have been set in the Salmon River: the Great Lakes record Chinook salmon (47 lbs. 13 oz.) and the world record Coho salmon (33 lbs. 4 oz.).
