The Logon or Logone River is a major tributary of the Chari River. The Logone's sources are located in the western Central African Republic, northern Cameroon, and southern Chad. It has two major tributaries. The Pendé River (Eastern Logone) in the prefecture Ouham-Pendé in the Central African Republic and the Mbéré River (Western Logone) at the east of Cameroon. Many swamps and wetlands surround the river.

Settlements on the river include Moundou, Chad's second-largest city, and Kousseri, Cameroon's northernmost city. Chad's capital city, N'Djaména, is at the spot where the Logone empties into the Chari river.

The Logone forms part of the international border between Chad and Cameroon.

Hydrometry

The flow of the river observed over 38 years (1951-84) in Bongor a town in Chad short after the union with the Pendé about 450 km above the mouth into the Chari.[1] It should be noted that due to the strong evaporation the amount of water to the estuary decreases. The at Bongor observed average annual flow during this period was 492 m³ / s fed by an area of ​​about 73.700 km ² approximately 94,5% of the total catchment area of the River. In his last part, in N'Djamena, there were only remaining 400 m³ / s.

The average monthly flow of the river Logone at hydrological station of Bongor (in m³ / s )< br /> (Calculated using the data for a period of 38 years, 1948-86)
