Шаблон:Infobox body of water Betqua 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 1997 by SAERT.[1]

Dam characteristics

  • Dam height: 16 metres
  • Dam crest length: 284 metres
  • Spillway width: 20 metres

Capacity

  • Original capacity: 666 337 m³
  • Dead storage: 133 267 m³
  • Reservoir area: 13.7 ha

In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 23 years.[1]

Irrigation

  • Designed irrigated area: 70 ha
  • Actual irrigated area in 2002: 25 ha

Environment

The catchment of the reservoir is 1.52 km² large, with a perimeter of 4.82 km and a length of 1520 metres. The reservoir suffers from rapid siltation.[2] 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.[3]
