Guaíra, Salto del

Prior to 1982, this was a massive waterfall. Sadly, it was flooded by the reservoir of a massive dam in 1982. While we understand the enormous hydropower potential of the Itaípu dam, it's sad the desire for electricity precluded shortening the height of the dam by roughly 150 feet. Salto del Guaíra was a voluminous waterfall that was similar to Iguaçu in basic shape, with greater volume, though not as tall or wide.
There were several named segments: Salto Arco-Íris, Salto Barão de Mauá, Salto Benjamim Constant, Salto do Caxias, Salto Deodoro, Salto Diretor Francis, Salto Floriano, Salto General Estigaríbi, Salto do Limite, Salto Marechal Lopes, Salto Maria Barreto, Salto Osório, Salto Presidente Franco, Salto Rabisco Mendes, Salto Ruy Barbosa, Salto Saldanha Gama, Salto Saltinho, Salto do Tamandaré, and Salto Thomás Laranjeira.
