Kaieteur Falls is a high-volume waterfall on the Potaro River in central Guyana, Potaro-Siparuni region. It is located in Kaieteur National Park. It is 226 meters (741 ft) high when measured from its plunge over a sandstone and conglomerate cliff to the first break. It then flows over a series of steep cascades that, when included in the measurements, bring the total height to 251 meters (822 ft). While many falls are greater in height, few have the combination of height and water volume. However, it is likely one of the most powerful waterfalls in the world.
Kaieteur Falls is about three times higher than the more well known Niagara Falls, located on the border between Canada and the United States and about two times the height of the Victoria Falls located on the border of Zambia and Zimbabwe in Africa. It is a single drop waterfall according to the World Waterfall Database which list it as 19th largest waterfall in terms of volume, and in their estimation, Kaieteur is the 26th most scenic waterfall in the world.
Its distinction lies in the unique combination of great height and large volume, averaging 663 cubic meters per second (23,400 cubic feet per second). Thus it is one of the most powerful waterfalls in the world, rivaling even the Jog Falls of India’s Karnataka state during the monsoon season. (from Wikipedia, the free encyclopedia)
