The Chari and Logone Rivers, both of which originate in the Central African Republic and flow northward, provide most of the surface water entering Lake Chad.

Although Chadian society is economically, socially, and culturally fragmented, the country's geography is unified by the Lake Chad Basin.

Once a huge inland sea ( the Pale-Chadian Sea ) whose only remnant is shallow Lake Chad, this vast depression extends west into Nigeria and Niger.

Lake Chad, located in the southwestern part of the basin at an altitude of 282 meters, surprisingly does not mark the basin's lowest point ; instead, this is found in the Bodele and Djourab regions in the north-central and northeastern parts of the country, respectively.

North and northeast of Lake Chad, the basin extends for more than 800 kilometers, passing through regions characterized by great rolling dunes separated by very deep depressions.

Southeast of Lake Chad, the regular contours of the terrain are broken by the Guéra Massif, which divides the basin into its northern and southern parts.

South of the Chadian border, the koros divide the Lake Chad Basin from the Ubangi-Zaire river system.

Farther north the western depression, known as the Albertine Rift is occupied for more than half its length by water, forming the Great Lakes of Tanganyika, Kivu, Lake Edward and Lake Albert, the first-named over 400 miles ( 600 km ) long and the longest freshwater lake in the world.

There is, however, in the centre a circular basin occupied by Lake Tsana.
