May Leiba is a reservoir located in the Dogu’a Tembien woreda of the Tigray Region in Ethiopia.

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.

The catchment of May Leiba reservoir is 17.87 km² large, with a perimeter of 17.61 km and a length of 4540 metres.

[1] The lithology of the catchment of the reservoir is Antalo Limestone, Agula Shale, sandstone of the Amba Aradam Formation and Ashangi Basalts.

While this doubled the garlic yield, it proved also to be a costly venture to transport the sediment from the dry lake bottom to nearby barren land in order to establish the plots.
