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.
Dam characteristics Dam height: 14 metres Dam crest length: 325 metres Spillway width: 15 metres
Capacity Original capacity: 296000 m³ Dead storage: 20832 m³ Reservoir area: 6.5 ha In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 30 years.
Irrigation Designed irrigated area: 20 ha Actual irrigated area in 2002: 3 ha
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. The lithology of the catchment is Mekelle Dolerite and 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.
