Dam characteristics

• Dam height: 17.8 metres
• Dam crest length: 433 metres
• Spillway width: 15 metres

Capacity

• Original capacity: 1 022 900 m³
• Dead storage: 153 435 m³
• Reservoir area: 17.24 ha

In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 22 years.[1]

Irrigation

• Designed irrigated area: 100 ha
• Actual irrigated area in 2002: 70 ha

Environment

The catchment of the reservoir is 7 km² large. The reservoir suffers from rapid siltation.[2][3] The lithology of the catchment is Adigrat Sandstone, Enticho Sandstone, tertiary basalt and Precambrian metavolcanics.[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.[4]
