This is a list of rivers by their average discharge, that is, their water flow rate. Here, only those rivers are shown whose discharge is more than 2,000 m3/s (71,000 cu ft/s).

For context, the volume of an Olympic-size swimming pool is 2,500 m3. The average flow rate at the mouth of the Amazon is sufficient to fill more than 83 such pools each second. The average flow of all the rivers in this list adds up to 1,192,134 m3/s.

Notes

  1. ^ Amazon river water flows into its estuary through Santa Mario River Channel
  2. ^ Because it has a larger discharge than the Mississippi River at their confluence, the Ohio River is technically the main stream of the Mississippi River System
  3. ^ If considered a river. The Detroit River may also be seen as a strait connecting Lake St. Clair with Lake Erie and separating the Lower Peninsula of Michigan from the Ontario Peninsula.
