Addi Shihu 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: 10.8 metres
• Dam crest length: 301 metres

Capacity

• Original capacity: 1 million m³
• Reservoir area: 36 ha

Irrigation

• Designed irrigated area: 40 ha
• Actual irrigated area in 2002: 13 ha

Environment

The catchment of the reservoir is 9.4 km² large. The reservoir suffers from rapid siltation. ^[2] 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. ^[3]
