Freshwater artificial lake in Ethiopia
Imbagedo is a reservoir located in the Inderta woreda of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 1998 by SAERT.[1]

Close
- Dam height: 20 metres
- Dam crest length: 328 metres
- Spillway width: 20 metres
- Original capacity: 1 776 278 m³
- Dead storage: 360 000 m³
- Reservoir area: 36 ha
In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 24 years.[1]
- Designed irrigated area: 80 ha
The catchment of the reservoir is 12.4 km² large. The reservoir suffers from rapid siltation.[2][3] 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.[4]
