Baro River at Gambela
|Mouth||Coordinates: into Sobat River|
|Basin countries||Ethiopia, South Sudan|
The Baro River (known to the Anuak as Upeno River) is a river in southwestern Ethiopia, which defines part of Ethiopia's border with South Sudan. From its source in the Ethiopian Highlands it flows west for 306 kilometres (190 mi) to join the Pibor River. The Baro-Pibor confluence marks the beginning of the Sobat River, a tributary of the White Nile.
The Baro river is created by the confluence of the Birbir and Gebba Rivers, east of Metu in the Illubabor Zone of the Oromia Region. It then flows west through the Gambela Region to join with the Pibor River, both of them creating the Sobat. Other notable tributaries of the Baro include the Alwero and Jikawo Rivers.
Of the Sobat River's tributaries, the Baro River is by far the largest, contributing 83% of the total water flowing into the Sobat. During the rainy season, between June and October, the Baro River alone contributes about 10% of the Nile's water at Aswan, Egypt. In contrast, these rivers have very low flow during the dry season.
The boundary between Sudan and Ethiopia was defined for the region near the Baro River in 1899 by Major H.H. Austin and Major Charles W. Gwynn of the British Royal Engineers. They had no knowledge of the land, its inhabitants, or their languages, and were short on supplies. Rather than defining a line based on ethnic groups and traditional territories, essentially along the escarpment that separates the highlands and the plains, they simply proposed drawing the line down the middle of the Akobo River and parts of the Pibor and Baro rivers. This boundary was consummated in the Anglo-Ethiopian Treaty of 1902, resulting in an area in Ethiopian Gambela Region called the Baro Salient. This area is more closely connected to South Sudan than Ethiopia, both in terms of natural features and people. The Baro Salient was used as a sanctuary by Sudanese insurgents during the country's long civil wars. It was difficult for Sudan to exert authority over a region that is part of Ethiopia, and Ethiopia was reluctant to police this remote region and become involved in the politics of Sudan's internal conflicts.
The only navigable river in Ethiopia, the Baro's most important city is Gambela, which served as a port from 1907 until the 1990s when civil war in Ethiopia and Sudan forced shipping on the river to be halted.
The second-longest bridge in Ethiopia crosses the Baro, connecting two parts of the Gambela Region. This bridge is 305 meters long.
