The Logone River is formed by tributaries flowing from Cameroon and Central African Republic.

Both shorter and smaller in volume than the Chari, it flows northeast for 960 kilometers ; its volume ranges from five to eighty-five cubic meters per second.

At N ' Djamena the Logone empties into the Chari, and the combined rivers flow together for thirty kilometers through a large delta and into Lake Chad.

At the end of the rainy season in the fall, the river overflows its banks and creates a huge floodplain in the delta.
