The Bahr Aouk River is a river in central Africa. It arises in eastern Chad at the border to Sudan and flows southwest, forming a significant portion of the international boundary between Chad and the Central African Republic. The Bahr Aouk meets the Chari River, which leaves the border and flows north into the Chad.
The flow of the river has been observed for over 22 years (1952–74) at Golongoso a town just short of the confluence with the Chari.[1] The measured average annual flow during this period was 74m3/s, draining an area of about 96000km2 which is a high proportion of the total catchment area of the river.
