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[edit]
- Dam height: 14 metres
- Dam crest length: 325 metres
- Spillway width: 15 metres
Capacity[edit]
- 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.[1]
Irrigation[edit]
- Designed irrigated area: 20 ha
- Actual irrigated area in 2002: 3 ha
Environment[edit]
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]
