Guairá Falls (Spanish: Saltos del Guairá, Portuguese: Salto das Sete Quedas do Guaíra) were a series of immense waterfalls on the Paraná River along the border between Paraguay and Brazil. The falls ceased to exist in 1982 when they were inundated by the impoundment of the Itaipu Dam reservoir. While published figures vary, ranging from 13,000 m3 (470,000 cu ft) per second[1] to 50,000 m3 (1,750,000 cu ft) per second,[2] Guaíra's flow rate was among the greatest of any then-existing falls on Earth.

The falls comprised 18 cataracts clustered in seven groups—hence their Portuguese name, Sete Quedas (Seven Falls)—near the Brazilian municipality of Guaíra, Paraná and Salto de Guairá, the easternmost city in Paraguay. 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 380 m (1,250 ft) to 60 m (200 ft). The total height of the falls was approximately 114 m (375 ft), while the largest individual cataract was 40 m (130 ft) high. The roar of the plunging water could be heard from 30 km (20 mi) away.[3]
