Inga Falls is a rapids 40 km from Matadi in the Democratic Republic of the Congo where the Congo River drops 96 m (315 ft) over the course of 15km (9 mi). At 42,476 m³/s (1,500,000 ft³/s), it is arguably the largest waterfall in the world. Its maximum recorded volume is 70,793 m³/s (2,500,000 ft³/s). Inga falls is also the site of two large hydroelectric dams, named Inga I & II, as well as two projected dams, one of which would be the largest (by power production) in the world.
