Corantijn

The Courantyne/Corentyne/Corantijn River flows through Suriname and Guyana in northern South America. It is the Longest River in Suriname, forming the border between Suriname and Guyana's East Berbice-Corentyne area. Kutari River, Coeroeni River, New River, and Zombie Creek are among its tributaries. The Guianan wet woods ecoregion is traversed by the river. It rises in the Acarai Mountains and travels northward via the Boven (Upper) Courantyne, the source river for roughly 724 kilometers (450 miles) between Guyana and Suriname, until emptying into the Atlantic Ocean in Corriverton, Guyana, and Nieuw Nickerie, Suriname. Between these two towns, a ferry service exists. The Courantyne River is home to the Wonotobo Falls, Frederik Willem IV (Anora) Falls, and King Edward VI Falls. Barrington Brown Falls, Drios Falls, and Maopityan Falls are among the other waterfalls.

The Tigri Area is located between the upper reaches of the Courantyne, Upper Courantyne, Coeroeni, and Koetari rivers, and is claimed by both Suriname and Guyana. The Guyanese–Surinamese boundary is the Guyanese river bank (the west bank of the river). Suriname considers the left bank of the Courantyne to be a border, however, Guyana disputes this and considers the center of the river to be a border, citing the Thalweg Doctrine. This issue, which has raged since the colonial era, was resolved in 2007 by a Hague Arbitration Court ruling that established the boundary between Guyana and Suriname on the left side of the river, as well as the river water body belonging to Suriname.
