Greater Angereb River

The Angereb also known as the Bahr as-Salam is a river of Ethiopia and eastern Sudan, and one of the sources of the Nile. It rises near Daqwa, north of Gondar in the Amhara Region, flowing west to join the Atbarah River. The historic district of Armachiho is located along part of its flow.

The Angereb Dam spans the river, built in 1986 for water supply purposes.
