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.[1]
In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 25 years.[1]
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.[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]
There is a (much larger) dam with the same name, some 20 km to the northwest: Gereb Segen (May Gabat)
