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 was estimated at 22 years.

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. The lithology of the catchment is Adigrat Sandstone, Enticho Sandstone, tertiary basalt and Precambrian metavolcanics. 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.
