14 de Julho
hydroelectric power station and dam
14 de Julho is a partially collapsed hydroelectric dam, formerly with around 100 MW of power, that is located in the Das Antas River between the municipalities of Cotiporã and Bento Gonçalves in Brazil. The dam had an estimated capacity of 55.18 million cubic meters before its collapse. Its construction project started in 2004 and subsequently entered into commercial operation in 2008.
Collapse
On May 2, 2024, the dam partially collapsed during heavy rains. After the collapse, the region has since been declared a state of emergency by Rio Grande do Sul state governor Eduardo Leite, and the Civil Defense issued a statement warning residents in regions around the Taquari River to leave their homes. The collapse of the dam created a two-meter (6.6-foot; 79-inch) wave that exacerbated the 2024 flooding of Rio Grande do Sul.
The Brazilian company Companhia Energética Rio das Antas (CERAN) later issued a statement stating that the dam collapse did not significantly alter the flow dynamics in the Taquari–Antas basin.
This brief starts where responsible research should: with the source description of “14 de Julho” as hydroelectric power station and dam. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as hydroelectric power station and dam. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated May 29, 2026. The linked authority identifier is Q10388345. Authority coordinates are -29.070, -51.675. 1 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2004, 2008 and 2024.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
