Dam characteristics

• Dam height: 14.7 metres
• Dam crest length: 128 metres
• Spillway width: 17 metres

In 2001, the life expectancy of the reservoir before it is filled with sediment was estimated at only 33 years.^[1]

Irrigation

• Designed irrigated area: 60 ha
• Actual irrigated area in 2001: 5 ha

Environment

The catchment of the reservoir is 4.92 km², with a perimeter of 9.62 km and a length of 3560 metres. The reservoir suffers from rapid siltation.^{[2] [3]} The lithology of the catchment is Antalo Limestone and Agula shale.^[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]
