Irrigation

Environment

The catchment of the reservoir is 0.72 km2 large, with a perimeter of 3.34 km and a length of 1210 metres. The reservoir suffers from rapid siltation. The lithology of the catchment is dominantly Agula shale and little Mekelle dolerite. 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.
