Ouham River
Ouham
The Ouham River is a significant natural watercourse in Central Africa, originating in the Central African Republic between the Nana-Mambéré and Ouham-Pendé prefectures. It flows northward into Chad where it joins the Chari River approximately 25 kilometers north of Sarh. This river serves as one of the main headwaters of the Chari River system. Its notable tributaries include the Baba, Fafa, Nana Bakassa, and Nana Barya rivers, contributing to its substantial drainage basin. Hydrological observations conducted over 33 years (1951–1984) at Moïssala, Chad, indicate an average annual flow of 480 cubic meters per second, fed by a catchment area of about 67,600 square kilometers, representing roughly 95% of the river's total watershed. The Ouham River plays an important role in the regional hydrology and ecology, supporting local communities and ecosystems along its course.
