Owasco River (also known as Owasco Creek, Owasco Lake Outlet, and Owasco Outlet) is a river in Cayuga County in the state of New York. The river drains Owasco Lake at Auburn and flows in a north-northwest direction before converging with the Seneca River north-northwest of Port Byron. The Owasco River Railway is named after the river.
The city of Auburn owns and operates a dam on the river, and empties the effluent from its wastewater treatment plant into the river.[2]
