Cataratas do Iguaçu registram recorde de vazão com chuvas no PR

As Cataratas do Iguaçu, localizadas em Foz do Iguaçu, no oeste do estado do Paraná, alcançaram a maior vazão de 2026. Com as recentes chuvas na região, o volume de água ficou cerca de dez vezes superior à média histórica, fazendo com que a água cobrisse a famosa passarela que aproxima os turistas das quedas.

Medição da Copel e marcas históricas De acordo com os dados obtidos pelo monitoramento da Copel às 17h, a vazão bateu a marca de 16 milhões de litros de água por segundo. Para comparação, em condições normais, o volume médio costuma ser de 1,5 milhão de litros por segundo.

Esse novo patamar ultrapassa o recorde anterior do ano, registrado em 14 de outubro, quando o fluxo chegou a 15,7 milhões de litros por segundo. Apesar da impressionante cheia atual, o volume ainda se mantém distante do recorde histórico de 2014, período em que as quedas alcançaram 46 milhões de litros por segundo.

Segurança e interdição da passarela A passarela principal está fechada preventivamente desde o dia 11 de outubro, seguindo protocolos de segurança que determinam o encerramento do acesso quando o volume ultrapassa 8,5 milhões de litros por segundo com tendência de alta.

Como medida extra para proteger a estrutura contra a força da correnteza, as grades de proteção foram retiradas nos dias seguintes, procedimento que não era realizado desde 2023.

“E como ela pega uma área maior, ela pode trazer árvores, troncos, que podem vir a bater na passarela, nos pilares, e ter algum dano à estrutura”, explicou Franzini, responsável pelas explicações técnicas sobre a estrutura.

O especialista também detalhou o comportamento do rio: “A partir de 15 milhões de litros por segundo, ela começa a passar por cima da passarela a água”. Sem as grades, a resistência diminui, reduzindo os riscos de prejuízos físicos ao local.

Funcionamento do Parque Nacional do Iguaçu Mesmo com o cenário de cheia extrema, o Parque Nacional do Iguaçu segue aberto ao público, embora com alterações importantes na circulação. A Trilha das Cataratas permanece acessível, mas áreas específicas continuam bloqueadas por motivos de segurança e monitoramento contínuo feito pela concessionária Urbia+Cataratas e pelo ICMBio.

Entre os locais temporariamente fechados estão a Passarela das Cataratas, o mirante inferior do Espaço Naipi, o Circuito São João, o Espaço Usina, o Caminho do Poço Preto e a Trilha da Canafístula. Já o Caminho das Bananeiras está fechado em razão de obras. Até o momento, não há previsão oficial para a normalização e reabertura completa dos atrativos.
