List of rivers by discharge

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 cubic metres per second (530,000 US gal/s; 440,000 impgal/s; 2,000,000 L/s). For context, the volume of an Olympic-size swimming pool is 2,500 cubic metres. So the flow rate at the mouth of the Amazon is sufficient to fill more than 83 such pools each second.
