The Banqiao Reservoir Dam (along with 63 other dams) in the Henan province of China failed in 1975, killing an estimated 171 000 people (although some reports suggest the number could be as high as 230 000). When the dam failed, it destroyed the homes millions of people and is considered the largest dam failure in history.

In August 1975, the region experienced an extreme flood, resulting in quantities of water falling that had not been considered during the construction of the dam. More than a year's worth of rain fell in only 24 hours, and the dam failed on August 8. Early on August 8, the dam was breached and 700 million cubic meters of floodwater was released, flooding communities and homes downstream. After this burst, a chain reaction began and the other 61 reservoirs located in the area collapsed—releasing another six billion cubic meters of floodwater. The water covered an area equal to 10,000 square kilometers. The failure to plan and account for extreme floodwaters resulted in the immediate death of 26,000 as a result of the water itself. 145 000 more people died as a result of epidemics and famine following the flood.
