The Three Gorges Dam is one of the biggest if not the biggest gravity dam in the world. China is currently seeing record flooding, with three-four days of rain still in the future for the area around the dam.
When the dam was under construction, they asked foreign consultants to come in and inspect the dam. The consultants noted poor concrete quality and insufficient rebar supports. The Chinese then kicked the consultants out and called them racist.
A good video of the extent of the flooding.
The dam itself has taken damage from a 2012 earthquake and is now currently stressed. If it were to break, millions of lives could be at stake, especially since a huge amount of power is wired through the dam, thus, if it breaks during the night, people could be making a blind rush into the dark and into a wall of water.

so far 34 million are affected.
“it is similar to the floods in 1998 that started around this time of the year and continued to September.”

From 2018:
What would the effects be if the Three Gorges Dam were to collapse?
If the Three Gorges Dam is completely collapsed, more than 10 billion cubic meters of reservoir water will be released in a short time, and the coast between the dam site and Shashi City will be directly impacted by flood waves, resulting in serious disaster losses. The Gezhouba Dam water conservancy project will be severely damaged, and Yichang is flooded in the area below the railway line, and the embankment of Zhicheng, the upper and lower Dizhou and the Jing Jiang flood areas will be flooded by the embankment of the West Bank of the West.
The maximum flow rate of the dam break peak will reach 100 - 2 million 370 thousand cubic meters per second. The flood peak will reach the Gezhouba Dam water control hub at 100 km per hour. The flood peak will still reach 310 thousand cubic meters per second, the flood damages the Gezhouba Dam dam and enters the city of Yichang. The flow rate in the Yichang city is still still. With 65 kilometers per hour and 4 to 5 hours after dam break, the water level of Yichang will reach 64 to 71 meters above sea level.
It is not only the water, something else is in the water:

The recent floods and floods in our province are frequent. In areas where schistosomiasis is endemic, the chances of contracting schistosomiasis will be greatly increased without strengthening self-protection. In order to prevent infection with schistosomiasis and protect your own health, it is necessary to understand schistosomiasis protection.

Wuhan Laowai:
Sunday 12th July I went back to the Yangzte river entrance to check the water levels. The authorities locked the gates. So, my only option was to walk around the side to take a look. The service road was even more flooded, and I could clearly see the water right up against the side gate.
As I am writing this description I can hear the rain pouring down. It is just a matter of time until the river bursts its banks and then I will be in the middle of another disaster.

The rising of the water in the Three Gorges Dam continues; now it is 154.17 m. http://www.cjh.com.cn/
That is about 1 m per day the last week, something has to be done in a few days otherwise there will be owerflow. This will have consequences in Wuhan and the surrounding areas.
This is a bridge, but in a few days it was a bridge:

Thanks for posting these. Impressive forces of nature.
Yesterday it was 154.17 m, now it is 155.76, 4.24 to overflow.
No, I was wrong, the limit for the water in the dam is not 160 m it is 175 m, according to https://www.researchgate.net/publication/314139496_Reflections_on_the_Three_Gorges_Project_since_Its_Operation

WUHAN, July 18 (Xinhua) — The Three Gorges reservoir in central China’s Hubei Province has seen the second flood along the Yangtze River in 2020, the largest one arriving at the reservoir so far this year. At 8 a.m. on Saturday, the inbound flow of water reached 61,000 cubic meters per second while the outbound flow was 33,000 cubic meters per second, with 45 percent of floodwater withheld in the reservoir, according to the China Three Gorges Corporation.
Three lower floodgates of the Three Gorges Dam opened to discharge the floodwater on Saturday morning, with various parameters of the dam at safety levels. After withholding rounds of floodwaters, the water level of the reservoir has reached 160.17 meters, more than 15 meters higher than the flood limit level.
It is expected that this round of floods will recede after it peaked on Saturday, but a new round of floods is forecast to arrive around July 21, according to the corporation.

The have increased the outbound flow 1 600 cubic meters to reduce the water level, and this will have effect on the flooding downstream, expect more videos showing more flooding in Wuhan etc.

talking about disasters:
the likelihood rises that the Kariba Dam (border between Zambia and Zimbabwe) will not just fail but fall. If the dam collapses, the BBC reported in 2014, a tsunami would tear through the Zambezi River Valley, a torrent so powerful that it would knock down another dam a hundred miles away, the Cahora Bassa in Mozambique — twin disasters that would take out 40 percent of the hydroelectric capacity in all of southern Africa.
