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.
Čadské jazero, situované na juhozápade povodia s nadmorskou výškou 282 m, prekvapivo neoznačuje najnižší bod povodia; namiesto toho ho nájdeme v regiónoch Bodele a Djourab na severe a severovýchode.
