Era is a reservoir located in the Atsbi Wenberta woreda of the Tigray Region in Ethiopia. The earthen dam that holds the reservoir was built in 1997 by SAERT.[1]
Dam characteristics
- Dam height: 16.73 metres
- Spillway width: 10 metres
Capacity
- Original capacity: 1 920 000 m³
- Dead storage: 480 000 m³
- Reservoir area: 37 ha
Irrigation
- Designed irrigated area: 100 ha
- Actual irrigated area in 2002: 95 ha
Environment
The catchment of the reservoir is 16 km2 large. The reservoir suffers from rapid siltation.[2] [3] 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]
