Environment
The catchment of the reservoir is 4.8 km² large, with a perimeter of 9.62 km and a length of 3670 metres. The reservoir suffers from rapid siltation.[2] The lithology of the catchment is Adigrat Sandstone and Enticho Sandstone.[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.[3]
