Шаблон:Infobox body of water Gereb Shegal 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]
Dam characteristics
- Dam height: 20 metres
- Dam crest length: 363 metres
Capacity
- Original capacity: 1000000 m³
- Reservoir area: 17.1 ha
Irrigation
- Designed irrigated area: 52 ha

Environment
The catchment of the reservoir is 8.67 km² large, with a perimeter of 12.12 km and a length of 4320 metres. The reservoir suffers from rapid siltation.[2][3] The lithology of the catchment is Mekelle Dolerite and Antalo Limestone.[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.[4]
