New River (South America)

The New River (Dutch: Nieuwe Rivier) is a river of South America. It forms the Western border of the Tigri Area, a disputed territory that is claimed by both Guyana and Suriname. From a Surinamese perspective it is also called the Upper Corantyne River.
The river rises in the Acarai Mountains and flows, together with the Coeroeni River, to the Courantyne River. The Oronoque River is a major tributary of the New River and within the Tigri Area. It was the location of a skirmish between Guyana Police Force and a Surinamese labor camp, 15 December 1967.
Even though the area is disputed, it still attracts illegal mining. In 1993, the Guyana Defense Force identified alluvial mining by Brazilian nationals.
