The fastest flowing river in the world is the Amazon River. When measuring by volume, the Amazon is also the largest river in the world.
With its impressive size, the Amazon River has been said to cover one-fifth of the world's total river flow. With no bridges or areas to cross due to its power and size, the Amazon is ranked by many sources as the world's swiftest flowing river. At its mouth, the Amazon is also said to dump somewhere around eight trillion gallons of water on a daily basis. Finally, the Amazon is around 150 foot deep — just another statistic that proves it is a big, powerful giant of a river.
