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 for, and should not be assumed to be a complete list of waterfalls which would otherwise qualify as globally significant based on this metric.
The Inga falls, whose status as a true waterfall is controversial, are currently incorporated into the Inga I and Inga II hydroelectric facilities. The volume of the river diverted is approximately 30% of the average discharge. The
Grand Inga Dam, potentially the world's largest by generating capacity, is also proposed to be built on the falls.[1]
A series of seven cataracts, also referred to as the Stanley Falls. The last and most significant of these cataracts, at
Kisangani, is known as Wagenia.[3] The Boyoma Falls marks the transition to the
Congo River from the
Lualaba River.[4]
A series of falls and rapids that when measured end-to-end is over 10 kilometres in width, making it the world's widest waterfall. Largest waterfall in
Asia by average flow rate.[5]
Prior to the development of the Oregon City area, it is thought the falls may have spanned as much as 762 metres across. Flow regulated by the
T. W. Sullivan Hydroelectric Plant.[18]
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.
Submerged beneath the
Columbia River following the completion of
The Dalles Dam in 1957. The rock formation responsible for the falls remains intact.[75][76]
The
Marimbondo Dam was built atop the upper portion of the falls in 1971. The section further upstream was submerged beneath the
Rio Grande, while the section below the dam was dewatered and are visible.[79]
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]
