Authorities in central China have blasted a dam to release surging waters behind it amid widespread flooding across the country that has claimed country that has claimed scores of lives.
The dam on the Chuhe River in Anhui province was destroyed with explosives early on Sunday morning, after which the water level was expected to drop by 70cm (more than 2ft), state broadcaster CCTV reported.
Water levels on many rivers, including the Yangtze, have been unusually high this year because of torrential rains.
Blasting dams and embankments to discharge water was an extreme response employed during China’s worst floods in recent years in 1998, when more than 2,000 people died and almost three million homes were destroyed.
Last week, the gargantuan Three Gorges Dam on the Yangtze opened three floodgates as the water level behind the massive dam rose more than 15m (50ft) above flood level.
Another flood crest is expected to arrive at the dam on Tuesday.

Elsewhere, soldiers and workers have been testing the strength of embankments and shoring them up with sandbags and rocks. Ten reservoirs on the Huai River have seen water levels exceeding warning levels by as much as 6.85 metres, according to the Huaihe River Commission of China’s Ministry of Water Resources. The 1,000km (620 mile) Huai River flows through major agriculture and manufacturing hubs in Henan, Anhui and Jiangsu provinces. China on Sunday raised the flood alert level in the Huai River region in the country’s east to Level II from Level III, the second highest on its four-tier scale.
On Saturday, firefighters and others finished filling in a 188m (620ft) break on Poyang Lake, China’s largest freshwater lake, that had caused widespread flooding across 15 villages and agricultural fields in Jiangxi province.
More than 14,000 people were evacuated.
Seasonal flooding strikes large parts of China annually, especially in its central and southern regions, but has been especially severe this summer.
More than 150 people have died or are missing in flooding and landslides brought on by the torrential rains — 23 of them since Thursday alone.
About 1.8 million people have been evacuated and direct losses attributed to flooding are estimated at more than 49 billion yuan (€4.8bn), according to the ministry of emergency management. Major cities have been spared so far, but concern has risen over Wuhan and other downstream metropolises that are home to tens of millions of people.–PA and Reuters
