Niger River to Lake Chad: Clarifying the Geography

A common geographical confusion: there is no "Niger Delta River"—only the Niger River, which forms a vast delta (the Niger Delta) in Nigeria before emptying into the Gulf of Guinea. Lake Chad, a shallow endorheic lake in the Sahel, lies over 4,000 km northeast of the Niger's mouth—separated by the entirety of northern Nigeria, Niger, and parts of Chad.

The Niger flows northeast from Guinea through Mali (including the Inner Niger Delta), Niger, and Nigeria. Lake Chad sits in a separate basin, fed primarily by the Chari-Logone system from the Central African Republic and Cameroon. The two systems are hydrologically distinct, though both are critical to the Sahel's water security.

Understanding this separation matters for transboundary water management, climate adaptation, and the millions who depend on each system.
