Gereb Segen with catchment

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]

Homonymous places

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