Sangha River

Sangha River (Kikongo: Nzâdi Sangha, Swahili: Mto Sanga, French: Rivière Sangha) is one of the principal right-bank tributaries of the Congo River in Central Africa. Formed by the confluence of the and the Kadéï River at Nola in the western Central African Republic, it flows for about 790 km (490 mi) through or along the borders of the Central African Republic, Cameroon and the Republic of the Congo before joining the Congo River near Mossaka.

The river drains a basin of approximately 213,400 km within the north-western Congo Basin, one of the world's largest continuous tropical rainforest regions. Its flow has been monitored at Ouésso, where the mean annual discharge was measured at 1,662 m/s between 1947 and 1983.

Much of the Sangha basin remains sparsely populated and is recognised for its exceptional biodiversity. The river flows through the Sangha Trinational, a transboundary conservation area that includes Dzanga-Ndoki National Park, Lobéké National Park and Nouabalé-Ndoki National Park. The area was inscribed as a UNESCO World Heritage Site in 2012 and provides habitat for species including the African forest elephant, western lowland gorilla and central chimpanzee.
