List of waterfalls by flow rate
From Wikipedia, the free encyclopedia
This list of waterfalls by flow rate includes all waterfalls which are known to have an average flow rate or discharge of at least 150 cubic metres per second (5,300 cu ft/s). The waterfalls in this list are those for which there is verifiable information, and the list should not be assumed to be a complete list of waterfalls which would otherwise qualify as globally significant based on this metric.
Largest extant waterfalls
Largest historic waterfalls
This list comprises the waterfalls which have ceased to exist due to the impoundment of their river(s) by a dam, or due to the diversion of the watercourse.

The section further upstream was submerged beneath the Rio Grande, while the section below the dam was dewatered and are visible.[79] | ||
| San Rafael Falls | 400 | 14,000 | 94 | 308 | 23 | 75 | Coca | 0°06′15″S 77°34′51″W | On 2 February 2020, a large sinkhole formed just above the falls, diverting its flow beneath a large band of rock (the former brink of the falls) which survived the collapse and became a natural bridge until it too collapsed. Although the river initially still fell over 100 m (330 ft) into the sinkhole, very rapid headward erosion has since left no significant waterfall at this location.[80][81][82] | ||
