Rivers of the Central African Republic: major streams and drainage basins

Major drainage systems

The nation’s waterways fall into two broad groups. The southern and western rivers ultimately feed the Congo River system and flow toward the Atlantic. The northern and central rivers drain into the Chari–Logone system and Lake Chad. These basins determine settlement, agriculture and transport corridors across different ecological zones.

Principal rivers (selected)

• Ubangi (Oubangui) — the largest river associated with the country, a major waterway on which Bangui, the capital, is situated.
• Mbomou (Bomu) — an important river in the southeast that links to the broader Ubangi system.
• Sangha — flows in the forested southwest and is part of the Congo Basin network.
• Chari — while mainly in neighboring countries, it receives several CAR tributaries that flow north toward Lake Chad.
• Ouham — a key northern river contributing to the Lake Chad watershed.
• Kotto, Ouaka, Bamingui, Gribingui, Mambéré, Kadéï — notable regional rivers and tributaries found across central and western areas.

Characteristics and uses

These rivers vary from seasonal streams in the north to large, perennial channels in the south. They support fishing, supply water for communities, irrigate small-scale agriculture and provide limited river transport in otherwise road-poor regions. Riverine forests and floodplains around major waterways are important for biodiversity and local livelihoods.

History, borders and conservation

Rivers have historically guided exploration and colonial boundary-making in Central Africa; several waterways still coincide with international frontiers. Today they are central to conservation efforts—wetlands and riparian forests harbor wildlife but face pressures from deforestation, mining and unsustainable fishing. Protecting river basins is critical for water security and ecosystem services across the country.

Further notes

Many smaller streams and seasonal channels are not listed here but are essential to local communities. For detailed inventories, hydrological maps and navigability information consult specialized databases and national surveys referenced by hydrology and environmental agencies.
