Dur Anbesa 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 2001 by SAERT.[1] The catchment of the reservoir is 10 km^2 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]

Dam characteristics

• Dam height: 18 metres
• Dam crest length: 605 metres
• Spillway width: 10 metres

Capacity

• Original capacity: 900 000 m³
• Dead storage: 115 598 m³
• Reservoir area: 14 ha

In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 36 years.[1]

Irrigation

• Designed irrigated area: 61 ha
