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 
 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.

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.
