Inda Zib'i is a reservoir located in the Inderta woreda of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 1999 by SAERT.[1]

Dam characteristics

Dam height: 12.34 metres
Dam crest length: 227 metres
Spillway width: 2 metres

Capacity

Original capacity: 182 593 m³
Dead storage: 20 000 m³
Reservoir area: 4.05 ha

In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 25 years.[1]

Irrigation

Designed irrigated area: 13 ha
Actual irrigated area in 2002: 0 ha

Environment

The catchment of the reservoir is 1.49 km² large, with a perimeter of 4.77 km and a length of 1320 metres. The reservoir suffers from rapid siltation.[2][3] The lithology of the catchment is Agula Shale.[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]
