The strength of the Amazon River in South America dwarfs other rivers on the planet. The amount of water flowing through the Amazon is greater than the amount carried by the Mississippi, the Yangtze, and the Nile combined.

The Amazon River in South America moves more water than any other river in the world, and it isn't even close. By "discharge volume," the Amazon averages about 209,000 cubic meters per second (209,000 m3/s). To put that in perspective, the Amazon’s flow is greater than the next seven largest rivers combined. It accounts for approximately 20% of all the fresh water that enters the world’s oceans from land. The river is so powerful that it creates a "plume" of fresh water in the Atlantic Ocean that can be detected up to 400 kilometers (approx. 250 miles) away from the river's mouth. While the Nile is often cited as the longest river (a title the Amazon also disputes), the Amazon is the undisputed king of volume and "drainage basin" size, covering an area of nearly 7 million square kilometers. In 2026, the Amazon remains the critical "lungs" and "water pump" of the planet, influencing weather patterns across the entire Western Hemisphere.
