Extreme floods have hit China’s Three Gorges dam, which recorded the largest inflow of water in its history, prompting officials to assure the public it would not be breached.

Inflows to the world’s largest hydro-electric dam reached 75m litres of water a second, according to state media.

By Thursday morning, 11 outlets of the dam had been opened to discharge 49.2m litres of water a second, the largest release since its construction.

After two months of heavy floods across central and south-west China, officials have promised the dam can withstand the flows.

A breach of the dam, a controversial and unprecedented feat of engineering along the Yangtze River, would be embarrassing for China, which took 12 years to build the megaproject, displacing millions and submerging swathes of land.
