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] The Owasco River was also used as a power source for the Auburn Prison in the early-to-mid nineteenth century, helping fuel the town's developing economy and for-profit prison.[3]
The United States Geological Survey (USGS) maintains one stream gauge along the Owasco River. It has been operation since October 1998, and is located about 200feet upstream from Genesee Street in Auburn.[4]
The station had a maximum discharge of per second and a gauge height of 8.34feet on April 4, 2005. It had minimum discharge of per second on March 30-31, 1999, and July 22, 1999.[4]
