Lake Giba is a reservoir under construction at the border of the Inderta; Kilte Awula'ilo and Dogu’a Tembien woredas of the Tigray Region in Ethiopia.

[2] The dam is aimed to provide drinking water to Mekelle and to regulate the river flow.

[1] Average annual sediment input to the reservoir by the main rivers was calculated as 3.8 million tonnes:[3] The dam will occupy the wide valley bottom at the river confluences, which is currently occupied by farmlands and bushlands.

Current dryland villages Ch’in Feres (in Inderta), Addi Atereman and Worgesha (in Dogu’a Tembien) will become lakeshore villages, and Genfel church in the homonymous gorge will be on the edge of Lake Giba.

[1] Part of its water is anticipated to be lost through seepage;[5] the positive side-effect is that this will contribute to groundwater recharge in the downstream areas.
