Hackensack River Hackensack River The Hackensack River is a river, approximately 45 miles (72 km) long, in the U.S. states of New York and New Jersey, emptying into Newark Bay, a back chamber of New York Harbor. The watershed of the river includes part of the suburban area outside New York City just west of the lower Hudson River, which it roughly parallels, separated from it by the New Jersey Palisades. It also flows through and drains the New Jersey Meadowlands. The lower river, which is navigable as far as the city of Hackensack, is heavily industrialized and forms a commercial extension
Geography of New York (state) state. The river takes its rise in Otsego Lake, and, flowing southwest to the Pennsylvania line, receives Charlotte River from the south and the Unadilla River from the north. After a course of a few miles in Pennsylvania, it again enters New York and flows in a general westerly direction to near the western border of Tioga County, whence it turns south and again enters Pennsylvania. Its principal tributary from the north is the Chenango River. The Tioga River enters New York from Pennsylvania near the eastern border of Steuben County, flows north, receives the Canisteo River from the west
