Tekezé River
The Tekezé River (Ge'ez: ተከዘ or ተከዜ), also known as the Takkaze River, is a major river of Ethiopia. For part of its course it forms a section the westernmost border of Ethiopia and Eritrea. The river is also known as the Setit in Eritrea, western Ethiopia, and eastern Sudan. According to materials published by the Ethiopian Central Statistical Agency, the Tekezé River is 608 kilometers (378 mi) long. The canyon which it has created is the deepest in Africa and one of the deepest in the world, at some points having a depth of over 2000 meters (6,562 feet).
Course
The Tekezé River rises in the central Ethiopian Highlands near Mount Qachen within Lasta, from where it flows west, north, then west again, forming the westernmost border of Ethiopia and Eritrea from the confluence of the Tomsa with the Tekezé at 14°11′N 37°31.7′E / 14.183°N 37.5283°E / 14.183; 37.5283 to the tripoint between the two countries and Sudan at 14°15′27″N 36°33′37″E / 14.25750°N 36.56028°E / 14.25750; 36.56028. After entering northeastern Sudan at the tripoint it joins the Atbarah River, which is a tributary of the Nile. The Tekezé is perhaps the true upper course of the Atbarah, as the former follows the longer course prior to the confluence of the two rivers.
