The Congo River Basin contains the Congo River, which drains central equitorial Africa, discharging on the Atlantic Coast. The Republic of the Congo lies to the northwest of the lower part of the river and the Democratic Republic of the Congo lies to the southeast of the lower part of the river and within its upper reaches. The river is navigable for most of its length, but cut off from the Atlantic Ocean by 3 major falls, one of which, Inga Falls, is the site of a major hydroelectic project, Inga Dam. This dam site is located just below Pool Malebo (Stanley Pool), site of Kinshasa (formerly Léopoldville) and Brazzaville.
Other upper basin countries include Central African Republic, Angola, Zambia, Tanzania, Burundi, and Rwanda. The Chambeshi River in Zambia, the Congo's longest tributary, is generally considered the source of the Congo. The Congo is 2,922 miles long (4,700 km), second in Africa after the Nile. Its average discharge is 41,800 m³/s (1,476,376 ft³/s). The area of the basin is 3,680,000 km² (1,420,848 mi²).
