Dam characteristics

• Dam height: 15.5 metres
• Dam crest length: 514 metres
• Spillway width: 10 metres

• Original capacity: 670 480 m³
• Dead storage: 60953 m³
• Reservoir area: 12.86 ha

In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 31 years.[1]

Irrigation

• Designed irrigated area: 60 ha
• Actual irrigated area in 2002: 7 ha

Environment

The catchment of the reservoir is 14.18 km² large, with a perimeter of 17 km and a length of 5360 metres. The reservoir suffers from rapid siltation.[2] The geology of the catchment is Mekelle Dolerite, Agula Shale, and, at the upper edge, 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]
