Environment

The catchment of the reservoir is 8.67 km² large, with a perimeter of 12.12 km and a length of 4320 metres. The reservoir suffers from rapid siltation.^[2][3] The lithology of the catchment is Mekelle Dolerite and Antalo Limestone.^[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]
