Шаблон:Infobox body of water Belesat is a reservoir located in the Inticho woreda of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 1997 by the Relief Society of Tigray.[1]

Dam characteristics

  • Dam height: 15 metres
  • Dam crest length: 308 metres
  • Spillway width: 19 metres

Capacity

  • Original capacity: 428 028 m³
  • Dead storage: 60 000 m³
  • Reservoir area: 7.4 ha

In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 15 years.[1]

Irrigation

  • Designed irrigated area: 32 ha
  • Actual irrigated area in 2002: 20 ha

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]
