Filiglig 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 1998 by SAERT.[1]

Dam characteristics

Capacity

In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 30 years.[1]

Irrigation

Environment

The catchment of the reservoir is 7.44 km2 large, with a perimeter of 14.23 km and a length of 5840 metres. The reservoir suffers from rapid siltation.[2] [3] The lithology of the catchment is Mekelle Dolerite and 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]
