Banqiao Dam Disaster EXPOSED — The Deadliest Dam Failure Hidden for 30 Years

The Banqiao Dam disaster of 1975 remains one of the most devastating dam failures ever recorded. In August 1975, Typhoon Nina stalled over Henan Province, bringing extraordinary rainfall that overwhelmed the Banqiao and Shimantan dams. What followed was a catastrophic chain reaction as dozens of downstream dams collapsed, flooding thousands of square kilometres and devastating entire communities. But the disaster was not simply about extreme weather. The story also involves dam design, limited discharge capacity, maintenance problems, failed communications, ignored engineering warnings, and the vulnerability created by a chain of interconnected reservoirs. The script describes hydrologist Chen Xing warning that Banqiao needed far greater flood discharge capacity, while the approved design had only five gates. The human aftermath was even more devastating, with disease, hunger, displacement, and enormous uncertainty surrounding the final death toll. Later estimates varied substantially, with official and independent figures differing over the full number of deaths. This video explores what happened that night, why the dam failed, how the cascade unfolded, and why the disaster remained largely unknown internationally for decades.
