This is a translation of an image, seen on Twitter, about the current state of the Three Gorges Dam. I've done my best to preserve the news voice, and to ensure the accuracy of all technical terms related to flood control.


On July 18th, Xinhua News reported that, as a result of heavy rainfall, on the 17th the "second 2020 Yangtze flood" began in the upper reaches of the Yangtze.

The Three Gorges Dam's inflow rose rapidly, reaching 61,000 cubic meters per second as of 8 AM on the 18th. This is the largest floodwater to reach Three Gorges since the beginning of the flood season. The dam's outflow was 33,000 cubic meters per second, with the flood-blocking rate passing 45%. After retaining several cycles of floodwater, the Three Gorges Dam's water level had reached 160.1 meters 15 meters above its flood limit level [the highest allowable water level for flood containment.]

The report acknowledged that the Three Gorges Hub Operations Department's testing record showed the dam to be undergoing "displacement, seepage, and deformation." However, the [Xinhua] report did not provide specific data on those factors; rather, it stated in general terms that the dam was "within ordinary limits," and emphasized that "safety indicators for all of the dam's water-blocking structures are stable."
