Gereb Segen (Hintalo)

Gereb Segen 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 2000 by SAERT.

Dam characteristics

 * Dam height: 14.86 metres
 * Dam crest length: 473 metres
 * Spillway width: 8 metres

Capacity
In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 25 years.
 * Original capacity: 337408 m³
 * Dead storage: 22400 m³
 * Reservoir area: 11.7 ha

Irrigation

 * Designed irrigated area: 24 ha
 * Actual irrigated area in 2002: zero ha

Environment
The catchment of the reservoir is 3.53 km2 large, with a perimeter of 11.66 km and a length of 5200 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.

Homonymous places
There is a (much larger) dam with the same name, some 20 km to the northwest: Gereb Segen (May Gabat)
