The Amazon River carries more water into the ocean than any other river.

The longer version

Discharge measures the volume of water passing a point each second. A wide channel, a deep cross section and steady rainfall across a huge basin all push that number upward. This river drains a basin fed by rain on both sides of the equator, so tributaries on different sides peak at different times and keep the flow strong through the year.

Seasonal flooding spreads water into the forest, carrying sediment that renews soil. The fresh water pushes far out to sea before mixing with salt water, creating a visible plume. Length contests with other rivers depend on which source stream is counted, but volume is not seriously disputed.
