Raritan River - Description

Description

The river forms at the confluence of the North and South Branches just west of Somerville at the border of Bridgewater, Branchburg, and Hillsborough Townships. It flows for approximately 16 mi (25.7 km) before slowing in tidewater at New Brunswick, and its estuary extends 14 mi (22.5 km) more entering the western end of Raritan Bay at South Amboy.

The river has served an important water transportation route since the days of the Lenape Native Americans. The name itself comes from an Algonquian word meaning "stream overflows." The name is also applied to the Raritan people, an Algonquian tribe that inhabited Staten Island, near the river's mouth. In colonial days, the river allowed the development of early industry around New Brunswick, as well as the transportation of agricultural materials from central New Jersey. During the American Revolutionary War, the river provided a means for troop conveyance. The construction of the Delaware and Raritan Canal along the right (south) bank of the river provided a critical link between New York City and Philadelphia, Pennsylvania on the Delaware River.

Comprehensive measures have been taken to reduce the pollution and increase the water quality. These actions have benefited the fish population which include (but are not limited to) largemouth bass, smallmouth bass, sunfish, catfish, trout, chain pickerel, american eels, carp and yellow perch. An occasional Pike and Musky have been taken out of the Raritan as well. The tidal portions of the river host migratory salt water species such as striped bass, fluke, winter flounder, weakfish and bluefish. Many nesting birds and water fowl make their homes in and along the length of the river. Crustaceans such as blue claw crab, fiddler crabs and green crabs are also found in the tidal sections of the river. Crayfish can be found further upstream.

The river is also used for recreational boating, including use by the rowing team of Rutgers University in New Brunswick. The river is featured in the title of Rutgers' alma mater, On the Banks of the Old Raritan, and its flooding is mentioned in the song. The musical 1776 mentions troops bathing in the Raritan River.

Geologists assert that approximately 6,000 years ago the lower Raritan provided the course of the mouth of the Hudson River. Following the end of the last ice age, the Narrows had not yet been formed and the Hudson flowed along the Watchung Mountains to present-day Bound Brook, then followed the course of the Raritan eastward into Lower New York Bay.

Near its mouth, the river is spanned by a New Jersey Transit railroad bridge which carries the North Jersey Coast Line; the Victory Bridge which carries Route 35 (connecting Perth Amboy and Sayreville, New Jersey); the Edison Bridge, which carries U.S. Route 9 (connecting Woodbridge Township and Sayreville); and the Driscoll Bridge, which carries the Garden State Parkway (connecting Woodbridge Township and Sayreville).
