“I assume the breach is no longer a danger.”
That seems to be the case.
The peak of the monsoon season is now past (late July/Early August), and water levels are within a manageable level (about 163 meters, down from last Sunday’s peak around 168 meters).
Apparently, they will use the design max level of 175 meters in the Winter, when there is little chance of floods, and they want to save water for steady electrical generation.

The first job of the dam is generating electricity, flood control is its secondary secondary mission. Generally, it trims off about 1/3 of a flood effect, for those downstream. When push comes to shove, they would release the floodwaters downstream, rather than allow the dam to top over (181 meters).
This year was something like a once in a hundred year flood season. There was pretty massive flood damage downstream from Three Gorges, which would have been worse without the dam. It sure looks like the dam has survived the test this year, but there is still some non-peak monsoon season to go, if God decides.
good news. tks for update!
