Site description The Akaki–Aba-Samuel wetlands are part of the Awash river catchment, c.20 km south-east of Addis Ababa. The wetlands consist of Aba-Samuel reservoir and an adjacent area that is inundated most of the year. The Akaki river consists of two main branches, the confluence of which is at the Aba-Samuel reservoir. The western branch of the river rises north-west of Addis Ababa on the flanks of Wechacha mountain and flows for c.40 km before it reaches the reservoir. The eastern branch of the river rises north-east of Addis Ababa and flows into Aba-Samuel reservoir after c.53 km. The reservoir was created in 1939 to produce electricity for Addis Ababa, and production continued until 1970 when the machinery became too old to maintain and the plant stopped working. Aba-Samuel reservoir catchment area is 1,495 km², and includes the catchment of the Lege Dadi dam. The reservoir originally had an area of 12,068 km², but the catchment has suffered much erosion resulting in silt deposition in the reservoir that has also been invaded by Eichhornia crassipes. Both of these factors have severely reduced the area of open water. The area around Akaki–Aba-Samuel is permanently marshy with small ephemeral lakes. The fringe of the marsh has some tall sedges, grasses and reeds. The rest of the area is farmland and grassland with a few scattered trees, mostly Faidherbia albida and figs.
