Largest river by volume of water

Estimated Oceans and rivers · Verified 2026-10-29 · WWV-SP-006

The Amazon discharges about 219,000 cubic metres of water every second into the Atlantic. That is roughly one fifth of all the fresh water flowing into the world's oceans.

Flow changes with the season and with the gauge location, so the figure is an average estimate.
