Dibdibo is a reservoir named after the homonymous village, located in the Inticho woreda of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 1999 by the Relief Society of Tigray.[1]

Dam characteristics

Capacity

In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 22 years.[1]

Irrigation

Environment

The catchment of the reservoir is 7 km² large. The reservoir suffers from rapid siltation.[2] [3] The lithology of the catchment is Adigrat Sandstone, Enticho Sandstone, tertiary basalt and Precambrian metavolcanics.[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]
