In Spanish it is called Saltos del Guairá, In Portuguese it's Salto das Sete Quedas do Guaíra- the Guaría falls were a bunch of waterfalls on the Paraná River along the border between Brazil and Paraguay. The falls no longer exist, they were rid of in 1982 by the of the Itaipu Dam reservoir. ranging from 470,000 cubic feet (13,000 m3) per second to 1,750,000 cubic feet (50,000 m3) per second, Guaíra's flow rate was among the greatest of any then-existing falls on Earth.
The falls had 18 cataracts clustered in seven groups— their Portuguese name, Sete Quedas (Seven Falls) relates. The falls were located at a point where the Paraná River was forced through a narrow gorge. At the head of the falls, the river narrowed sharply from a width of about 1,250 feet (380 m) to 200 feet (61 m). The total height of the falls was approximately 375 feet (114 m), while the largest individual cataract was 130 feet high. The roar of the water could be heard from 20 miles away.
