The name Raritan possibly derives from a branch of the Lenape people called the Nariticongs, the first people known to settle the Raritan Valley. Following conflict with the arriving Dutch colonists, the native people of the region were forced to sell their territory near the

and move further inland along the river valley. As English colonists took over the region, they took advantage of the river's location between New York and Philadelphia as well as a road network developed by the Lenape to turn the region into a transportation and commercial hub.DeAngelo, W.

The vast majority of traffic along the canal was Pennsylvania anthracite coal with the rest consisting mostly of agricultural goods, and at its peak in 1866 it transported more cargo than the Erie Canal. In 1932 the canal shut down for commercial use, though in 1974 it was turned into a state park for recreational use and remains used as a water supply for Central New Jersey.

Flooding

The Raritan River has persistent flooding problems when excessive rain from storms affects the river basin. The flooding problems mainly affect the town of Bound Brook, which is partially built on a natural floodplain at the junction of several tributaries, and Manville, which has a large neighborhood known as Lost Valley that lies on the floodplain between the Raritan River and its largest tributary river, which is known as the

. Other towns in the Raritan River basin also experience flooding to a lesser degree. Record flooding in the aftermath of

swept through the area. This problem was exacerbated by well-above average rainfall that fell in the weeks before the storm hit, and spurred completion of the Army Corps of Engineers flood control project. As of 2015, the current status of this project is: # The R2 levee system is functionally complete – The R2 Levee System is designed to provide Bound Brook with protection from a 150-year flood level. The levee is built to the height of the raised Talmage Avenue Bridge. # Closure gates along Raritan are functionally complete – The gate closures across the New Jersey Transit railroad tracks on the western side of Bound Brook and at the South Main Street railroad underpass that leads to Queens Bridge have been completed and are used to keep flood waters out of Bound Brook. # The new Talmadge Avenue Bridge that connects Bound Brook and

is functionally complete. The replacement bridge was built to the height of the R2 Levee to prevent Middle Brook and Raritan River waters from entering Bound Brook from the west. # To improve water flow through Bound Brook, the former Conrail bridge over the Raritan River and its associated railroad embankment that were located east of Bound Brook were removed during 2007. The bridge and embankment, when they were in place, acted to block the river flow through the Bound Brook area. To build the main Bound Brook R2 levee, the bridge and embankment needed to be removed.Valinski, Robin Blackstone, "Green Brook Flood Control Project: Saving Bound Brook" (2012).
