On Thursday afternoon, workers hired by the local government stacked up sandbags beside the Yangtze River to protect against a different kind of threat. Nearby, dozens more hurried to close ferry gates and build a temporary brick wall, lined with hay mats and supported by sandbags behind, while officials were stationed in watch posts along the river bank to monitor rising water levels.

One worker, who declined to give his name, said he had toiled around the clock to prepare for the heavy rain expected in the coming days. He said a wall of sandbags two metres high had been built to reinforce the embankment.

“The water is rising fast,” he said. “It only reached my ankle yesterday, but it is up to my knee now.”

Some parts of the riverside promenade had been closed to visitors, although many locals ignored police warnings by entering taped-off sections to go swimming.

The Wuhan government has ordered the closure of 188 ferry gates, shut down river ports and deployed over 12,000 people to patrol vulnerable spots along the Yangtze and its tributaries.

On Thursday, a water level at the Hankou Port in Wuhan reached 27.91 metres (91.6 feet), 61cm above alert level. The water level is expected to keep rising, with more heavy rain forecast in the coming days and increased water inflow from the tributaries.

Also on Thursday, the local government released a report explaining that because of Wuhan’s geography – sandwiched between Dongting Lake and the Hanjiang River on the upstream and Poyang Lake on the downstream – the city would be vulnerable to flooding if the heavy rain persisted.

Some local residents expressed dismay at their city’s misfortune so soon after enduring another crisis.

“Wuhan has just emerged from Covid-19, and now comes the flood. It’s such a disastrous year,” Mei Renxiang, a Wuhan resident, said. “It’s flooding everywhere; everywhere I look, it’s water. I have rarely seen anything like this. I hope we can all make it through this time.”

Some older residents still have vivid memories of past floods. A man surnamed Wang, who went swimming on Thursday, said the city had experienced flooding before but the situation had never been too serious.

“I’m not nervous at all,” he said. “We’ll be fine as long as we are prepared.”
