Facts About The Hudson River For Kids


The Hudson River is a 315-mile watercourse that flows from north to south through eastern New York State in the United States.The river begins at the confluence of Calamity Brook and Indian Pass Brook near Henderson Lake in Newcomb, New York. The river flows southward past the state capital at Albany and then eventually forms the boundary between New York City and the U.S. state of New Jersey at its mouth before emptying into Upper New York Bay.

  • This formed during the most recent North American glaciation over the latter part of the Wisconsin Stage of the Last Glacial Maximum, 26,000 to 13,300 years ago.
  • Tidal waters influence the Hudson’s flow as far north as Troy, New York.
  • The Dutch called the river the “North River” – with the Delaware River called the “South River” – and it formed the spine of the Dutch colony of New Netherland.
  • During the eighteenth century, the river valley and its inhabitants were the subject and inspiration of Washington Irving, the first internationally acclaimed American author.
  • In the nineteenth century, the area inspired the Hudson River School of landscape painting, an American pastoral style, as well as the concepts of environmental conservation and wilderness.
  • The actual Hudson River begins several miles north of Tahawus at the confluence of Calamity Brook and Indian Pass Brook near Henderson Lake in Newcomb, New York.
  • The Hudson is joined at Waterford (north of Albany) by the Mohawk River, its major tributary, just south of which the Federal Dam separates the Upper Hudson River Valley from the Lower Hudson River Valley or simply the Hudson River Valley.
  • The Hudson river then flows south, passing between the Catskill Mountains and the Taconic Mountains, widening significantly at the Tappan Zee, finally flowing between Manhattan Island and the New Jersey Palisades and into the Atlantic Ocean at New York Bay, an arm of the ocean, where it forms New York Harbor.
  • The lower Hudson is actually a tidal estuary, with tidal influence extending as far as the Federal Dam at Troy.
  • The Hudson is often mistaken for one of the largest rivers in the United States, but it is an estuary throughout most of its length below Troy and thus only a small fraction of fresh water, about 15,000 cubic feet per second, is present.
  • A barge canal now splits from the Hudson at that point, taking roughly the same route to Lake Champlain at Whitehall.
  • The New York, West Shore and Buffalo Railway began at Weehawken Terminal and ran up the west shore of the Hudson as a competitor to the merged New York Central and Hudson RiverRailroad.
