Comparisons to other famous fallsEleanor Roosevelt reportedly exclaimed "Poor Niagara!" (which, at 50 m or 165 feet, are a third shorter). Iguazu is also often compared with Southern Africa's Victoria Falls which separates Zambia and Zimbabwe. Iguazu is wider, but because it is split into about 275 discrete falls and large islands, Victoria is the largest curtain of water in the world, at over 1,600 m (5,249 ft) wide and over 100 m (328 ft) in height (in low flow Victoria is split into five by islands; in high flow it can be uninterrupted). The only wider falls are extremely large rapid-like falls such as the Boyoma Falls.
With the flooding of the Guaíra Falls in 1982, Iguazu currently has the second-greatest average annual flow of any waterfall in the world, after Niagara, with an average rate of 1,746 m3/s (61,660 cu ft). Its maximum recorded flow was 12,800 m3/s (452,000 cu ft/s). By comparison, the average flow of Niagara Falls is 2,400 m3/s (85,000 cu ft), with a maximum recorded flow of 8,300 m3/s (293,000 cu ft/s). The average flow at Victoria Falls is 1,088 m3/s (38,420 cu ft/s), with a maximum recorded flow of 7,100 m3/s (250,000 cu ft/s).
