Шаблон:Infobox body of water Addi Akhor is a reservoir located in the Enderta district of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 1998 by SAERT.[1]
Dam characteristics
- Dam height: 18 metres
- Dam crest length: 210 metres
- Spillway width: 1.3 metres
Capacity
- Original capacity: 510 777 m³
- Dead storage: 6008 m³
- Reservoir area: 8.19 ha
In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 30 years.[1]
Irrigation
- Designed irrigated area: 30 ha
- Actual irrigated area in 2002: 20 ha
Environment
The catchment of the reservoir is 2.75 km² large. The reservoir suffers from rapid siltation.[2] The lithology of the catchment is Antalo Limestone 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]
