Baro River

The Baro River or Baro/Openo Wenz, also known as the Openo River by the Anuak, is a river in southwestern Ethiopia that forms part of Ethiopia's border with South Sudan. It flows west for 306 kilometers (190 miles) from its source in the Ethiopian Highlands to join the Pibor River. The confluence of the Baro and Pibor rivers marks the beginning of the Sobat River, a tributary of the White Nile.

The Baro and its tributaries drain a watershed covering 41,400 km2 (16,000 sq mi). The average annual discharge of the river at its mouth is 241 m3/s (8,510 ft3/s).

The Baro/Openo River is formed by the confluence of the Birbir and Gebba Rivers east of Metu in the Oromia Region's Illubabor Zone. It then flows west through the Gambela Region, merging with the Pibor River to form the Sobat. The Alwero and Jikawo Rivers are two other notable tributaries of the Baro/Openo. To the west of Jikawo, the Baro River merges with the Pibor River. During the rainy season, the river floods to form the vast inundated area to the east and south of Jikawo, previously reaching as far east and south as Abobo and Gog.
