May Leiba is a reservoir located in the Dogu’a Tembien woreda of the Tigray Region in Ethiopia. It is named after the May Leiba River. The earthen dam that holds the reservoir was built in 1998 by the Relief Society of Tigray.[1]

In 2002, the life expectancy of the reservoir (the duration before it is filled with sediment) was estimated at 15 years.[1]

Irrigation
- Designed irrigated area: 50 ha
- Actual irrigated area in 2002: 5 ha
A first problem is administrative: the dam is located in one ‘’tabia’’ and the command area in another ‘’tabia’’, leading to disagreements with regard to the sharing of the water. The larger part of the water that could be used for formal irrigation is lost through seepage across the limestone;[2] the positive side-effect is that this contributes to groundwater recharge,[3] particularly around the downstream settlement of Addi Idaga, where a large irrigation perimeter has been developed.
