Hutchinson River

The Hutchinson River begins in Westchester County, flows through the Borough of the Bronx, and empties into Eastchester Bay. This system is a tributary of the East River, which lies immediately to the west of Long Island Sound. The Hutchinson River runs through the areas of Eastchester, Co-Op City, Baychester, Spencer Estates, Country Club, Eastchester Bay and Edgewater Park. The river is tidal throughout the Bronx, but receives freshwater input in Westchester County. The watershed is bordered on the north by Westchester County, the west by the Westchester Creek watershed, the east by Long Island Sound and the south by the Eastchester Bay.

Long Term Control Plan

DEP completed a Long Term Control Plan (LTCP) to better understand CSO impacts on water quality within the Hutchinson River. Throughout the LTCP’s development the City collected water quality data, performed extensive modeling, held multiple public meeting and analyzed potential projects based on costs and anticipated water quality.
