• Actual irrigated area in 2002: 3 ha

Environment

The catchment of the reservoir is 7.44 km² large, with a perimeter of 14.23 km and a length of 5840 metres. The reservoir suffers from rapid siltation.^[2][3] The lithology of the catchment is Mekelle Dolerite 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]
