Giba River

The Giba is a river of northern Ethiopia. It starts at the confluence of Genfel and Sulluh (which rises in the mountains of Mugulat) (3,298 metres above sea level) and flows westward to the Tekezé River. Future Lake Giba will occupy the plain where the Sulluh, Genfel and Agula'i Rivers meet, and hence be the future source of Giba River.
