Gereb Awso
Gereb Awso 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. Environment. The catchment of the reservoir is 1.21 km² large, with a perimeter of 4.62 km and a length of 1780 metres. The reservoir suffers from rapid siltation. The lithology of the catchment is Agula Shale. 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.
