Шаблон:Short description Шаблон:Infobox body of water Addi Gela is a reservoir located in the Hintalo Wajirat woreda of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 1998 by SAERT.[1]

Dam characteristics

  • Dam height: 22 metres
  • Dam crest length: 424 metres
  • Spillway width: 14 metres

Capacity

  • Original capacity: 1 250 000 m³
  • Dead storage: 62 500 m³
  • Reservoir area: 18.5 ha

In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 40 years.[1]

Irrigation

  • Designed irrigated area: 100 ha
  • Actual irrigated area in 2002: 6 ha

Environment

The catchment of the reservoir is 8.19 km2 large, with a perimeter of 13.43 km and a length of 5640 metres. The reservoir suffers from rapid siltation.[2] The lithology of the catchment is Agula Shale, Mekelle Dolerite, and sandstone of the Amba Aradam Formation.[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]
