Addi Akhor

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.

Dam characteristics

 * Dam height: 18 metres
 * Dam crest length: 210 metres
 * Spillway width: 1.3 metres

Capacity
In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 30 years.
 * Original capacity: 510 777 m³
 * Dead storage: 6008 m³
 * Reservoir area: 8.19 ha

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. The lithology of the catchment is Antalo Limestone and Mekelle Dolerite. 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.
