The most powerful stretch of rapids in the world

What is it?

Inga Falls is not one single waterfall but a long stretch of wild, thundering rapids on the lower Congo River. An enormous amount of water crashes through a narrow rocky canyon here โ€” more water than passes through any other waterfall or rapids in the world. It is one of the most powerful natural places on the whole planet.

Tell me more

At Inga Falls the Congo River squeezes through a canyon and drops about 96 metres over a stretch of about 15 kilometres. The water moves with incredible force โ€” far more energy is packed into this one stretch of river than in any similar place on Earth. Engineers say that if the rapids were harnessed for electricity, they could power a very large portion of the entire African continent.

The sound of Inga Falls is extraordinary. From a distance you hear a deep, constant roar like a storm that never stops. Up close, the white water crashes against black volcanic rocks, throwing up clouds of spray that catch the sunlight and create shimmering rainbows.

Because the river moves so violently here, Inga Falls has created its own remarkable wildlife world. Certain fish have evolved specifically to survive in the furious current โ€” some cling to rocks with their mouths while others have extra-powerful tails for swimming against the flow.

Inga Falls reminds us how full of energy our natural world truly is. The water here has been rushing through this canyon for millions of years, long before any human being arrived to marvel at it.

Discussion prompts

  1. 01Inga Falls has more flowing water than anywhere else on Earth. How do you think early explorers felt when they first saw it?
  2. 02Moving water can make electricity. Can you think of other things in nature that contain energy we can use?
  3. 03Animals have adapted specially to survive in the rapids. What is an adaptation, and can you think of one in an animal you know?

Classroom activity

In pairs, design a poster called 'Rivers Are Energy'. Show two ways a river can have energy โ€” moving things downstream, and powering machines. Include a drawing of Inga Falls and label the water, the rocks, the spray and one adapted animal.
