  • Addi Qenafiz is a reservoir located in the Hintalo Wajirat woreda of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 1998 by SAERT.


    Dam characteristics


    Dam height: 15.5 metres
    Dam crest length: 514 metres
    Spillway width: 10 metres


    Capacity


    Original capacity: 670 480 m³
    Dead storage: 60953 m³
    Reservoir area: 12.86 ha
    In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 31 years.


    Irrigation


    Designed irrigated area: 60 ha
    Actual irrigated area in 2002: 7 ha


    Environment


    The catchment of the reservoir is 14.18 km² large, with a perimeter of 17 km and a length of 5360 metres. The reservoir suffers from rapid siltation. The geology of the catchment is Mekelle Dolerite, Agula Shale, and, at the upper edge, the Amba Aradam Formation. 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.
