Chad’s world heritage site ‘includes eighteen interconnected lakes in the hyper arid Ennedi region of the Sahara desert. While Ounianga Kebir comprises of lakes: Lake Yao, Lake Katam, Lake Oma(or Ouma), Lake Bever, Lake Midji and Lake Forodom,  Ouniang Serir comprises Lake Melekui, Lake Dirke, Lake Ardjou, Lake Téli, Lake Obrom, Lake Élimé, Lake Hogo, Lake Djiara, Lake Ahoita, Lake Daléyala, and Lake Boukkou. Lake Motro is southeast of Ounianga Kébir.

These eighteen lakes hold migrants’ memory of their ‘first-land’ ; in the  native geographical grips remains the ‘inhabited world’ in such a magnificent way that the names of lakes tell the story of the ancient migration. Scholars connect this migration to have happened at the end of the last ice age about 11,000 years ago. They also speak of the desert returned to the area about 5,000 years ago. But the real migration occurred sometimes in 9^th c A.D. only after the Flood along with volcanic eruption. These eighteen names are amazingly reflect on the geographical situation of the ‘first-land’.
