Environment


The catchment of the reservoir is 9.71 km² large, with a perimeter of 14.24 km and a length of 4960 metres. Due to the possibility to by-pass sediment-laden water, the reservoir suffers from less rapid siltation.[2][3] The lithology of the catchment is Agula Shale and Mekelle Dolerite.[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]
