Dam characteristics

• Dam height: 22 metres
• Dam crest length: 424 metres
• Spillway width: 14 metres

Capacity

• Original capacity: 1 250 000 m³
• Dead storage: 62 500 m³
• Reservoir area: 18.5 ha

In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 40 years.[1]

Irrigation

• Designed irrigated area: 100 ha
• Actual irrigated area in 2002: 6 ha

Environment

The catchment of the reservoir is 8.19 km² large, with a perimeter of 13.43 km and a length of 5640 metres. The reservoir suffers from rapid siltation.[2] The lithology of the catchment is Agula Shale, Mekelle Dolerite, and sandstone of the Amba Aradam Formation.[1] Part of the water that could be used for irrigation is lost through seepage; the positive side-effect is that this contributes to groundwater recharge.[3]
