Irrigation

  • Designed irrigated area: 80 ha
  • Actual irrigated area in 2002: 38 ha

Environment

The catchment of the reservoir is 17.16 km² large, with a perimeter of 20.38 km and a length of 4910 metres. The reservoir suffers from rapid siltation.[2][3] The lithology of the catchment is Mekelle Dolerite and Agula Shale.[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]
