Шаблон:Infobox body of water Gereb Bi’ati is a reservoir located near Mekelle in the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 2000 by SAERT.[1]

Dam characteristics

  • Dam height: 17 metres
  • Dam crest length: 578 metres
  • Spillway width: 40 metres

Capacity

  • Original capacity: 1005841 m³
  • Dead storage: 232728 m³
  • Reservoir area: 17 ha
  • Designed irrigated area: 88 ha

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]
