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. The lithology of the catchment is Mekelle Dolerite and Agula Shale. 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.
