Lake Assal ( , literally 'honey lake') is a crater lake in central-western Djibouti. It is located at the western end of Gulf of Tadjoura in the Tadjoura Region, touching Dikhil Region, at the top of the Great Rift Valley, some west of Djibouti city. Lake Assal is a saline lake which lies below sea level in the Afar Triangle, making it the lowest point on land in Africa and the second-lowest land depression on Earth after the Dead Sea. No outflow occurs from the lake, and due to high evaporation, the salinity level of its waters is 10 times that of the sea, making it the most saline in the world after Don Juan Pond. Lake Assal is the world's largest salt reserve, which is exploited under four concessions awarded in 2002 at the southeast end of the lake; the major share of production (nearly 80%) is held by Société d’Exploitation du Lac and Société d’Exploitation du Salt Investment S.A de Djibouti.
