Шаблон:Short description Шаблон:Infobox lake Addi Amharay is a reservoir located in the Inderta 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: 14.7 metres
  • Dam crest length: 128 metres
  • Spillway width: 17 metres

Capacity

  • Original capacity: 957,000 m³
  • Dead storage: 175,000 m³
  • Reservoir area: 31.5 ha

In 2001, the life expectancy of the reservoir before it is filled with sediment was estimated at only 33 years.[1]

Irrigation

  • Designed irrigated area: 60 ha
  • Actual irrigated area in 2001: 5 ha

Environment

The catchment of the reservoir is 4.92 km², with a perimeter of 9.62 km and a length of 3560 metres. The reservoir suffers from rapid siltation.[2] [3] The lithology of the catchment is Antalo Limestone 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]
