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]
In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 30 years.[1]
The catchment of the reservoir is 2.75 km2 (1.06 sq mi) 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]
