The Cohocton River, sometimes referred to as the Conhocton River, is a 58.5-mile-long (94.1 km) tributary of the Chemung River in western New York in the United States. Via the Chemung River, it is part of the Susquehanna River watershed, flowing to Chesapeake Bay. The name "Cohocton" is derived from an Iroquois term, Ga-ha-to, meaning "log floating in the water" or "trees in the water".New York State Route 17 follows the valley of the river along much of its route through Steuben County. The river is a popular destination for fly fishing. Source: Wikipedia
