Hydrometry

The flow of the river has been observed over 38 years (1951–84) in Bongor a town in Chad downstream of the union with the Pendé about above the mouth into the Chari. The Bongor observed average annual flow during this period was fed by an area of about approximately 94.5% of the total catchment area of the River. Due to the strong evaporation, the amount of water flowing into the estuary decreases. In N'Djamena, the flow reduces to .

Population

In the eastern lower Logone valley formed out of the Kotoko population several historic sultanates ( Kousseri, Logone-Birni, Makari-Goulfey and others) which were vassals of the Bornu or Baguirmi inside the borders of modern-day Cameroon.

September 2013 dam failure and flood

On the night of September 17 to September 18, 2013, heavy rains caused a rupture of the dam along the Logone River at the town of Dougui, Kai Kai District in the Far North Region of Cameroon. This caused initial evacuations of people to the banks of the dam. On September 27, a second rupture in the dam from the first rupture started flooding the area and nearly 9,000 people were displaced.
