Didessa River
From Wikipedia, the free encyclopedia
The Didessa River is a river in western Ethiopia. A tributary of the Abbay River, it rises in the mountains of Gomma, flowing in a northwestern direction to its confluence. The drainage area of the Didessa include parts of the Benishangul-Gumuz Region and parts of the Mirab Welega Zone of the Oromia Region.
Its own tributaries include the Wam, Enareya, Aet, Angar and Dobana rivers. Downstream of its junction with the Angar, the Didessa is rapid-free and potentially navigable.
