Bronx River

The Bronx River, approximately 24 miles long, flows through southeast New York in the United States and drains an area of 38.4 square miles. It is named after colonial settler Jonas Bronck. The Bronx River is the only fresh water river in New York City.It originally rose in what is now the Kensico Reservoir, in Westchester County north of New York City. With the construction of the Kensico Dam in 1885, however, the river was cut off from its natural headwaters and today a small tributary stream serves as its source.
