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: 957000 m³
- Dead storage: 175000 m³
- Reservoir area: 31.50 ha
In 2001, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 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 large, with a perimeter of 9.62 km and a length of 3560 metres. The reservoir suffers from rapid siltation.[2] 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.[3]
