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
Colonial history of New Jersey existed for the 26 years between 1674 and 1702. Determination of an exact location for a border between West Jersey and East Jersey was often a matter of dispute, as was the border with New York. The border between the two sides reached the Atlantic Ocean to the north of Atlantic City. The border line was created by George Keith, and can still be seen in the county boundaries between Monmouth and Burlington/Mercer Counties; Burlington and Ocean Counties; and Hunterdon and Somerset Counties, reaching upward to a point on the Delaware River which is just north of the Delaware Water
