You're all missing something here.

The area in the circle is believed to be silt buildup. Now, most dams have methods of dealing with silt, but given China's safety standards, I wouldn't be surprised if those systems either aren't in place or have broken down. What if they aren't pumping out more water because they CAN'T? Also, what if that water height figure isn't taking into account a silt buildup at the base of the dam? Another thing, what would the stresses of silt buildup do to a dams structural integrity?

Check out the garbage buildup near the side of the dam. Nasty.

Edit:I almost didn't notice this. Take a look at this road on the left of the image

Now take a look at where it was previously from a different angle.

I think this flooding is much higher than the reported numbers by this point.

Wow, I totally missed this.

2020 really is the Year of the Happenings, isn't it? Judging from how much water that dam is already holding, it looks like we have our July/August episode planned out.

Xinhua News (the source quoted) is reporting that the number was 61k at 8 pm on the 18th, but reduced to around 46k by 8 pm on the 19th (about 16 hours ago, I believe). At least that's what I read on their English site. (archive) It didn't mention the structural compromises anywhere that I could find on there, so either it's been hidden away from English speakers or I'm just shit at finding things on their crappy site.

Gotcha. Yeah, I could not find the source for the text quoted in that image either. Regardless, I don't think the dam is on the brink of busting yet. Supposedly it operated at full capacity, all 175m, for a while in 2010 under normal circumstances. Here's a crappy image from an archived puff piece.

EDIT: More low res images of the dam at full capacity in 2010, if it interests anyone.

We'll see what the rest of this rainy season brings.

Silt build up uas actually been something western engineers have bitched about for years when it comes to the 3 gorges dam. All the way back to start of the project the CCP was warned such a massive barrier will inevitably lead to build up. And even a cursory google search shows the CCP has every couple of years or so "beaten the silt problem". Apparently it's a problem they need to beat quite regularly.

This could be catastrophic if they are lying about it. At the low end, sediment build up reduces the ability of the spillways to release pressure from the reservoir. At the worst end, the backlog delta sediment pile could slip in an underwater landslide, sending a sudden tsunami of Force against the Dam Wall itself which is already strained to capacity

From these photos it looks like they still have plenty of the gates closed.

Looks like 6/8 gates are open to me. Not sure how many gates there are. Can't find the info from a cursory search.

 

[jje100010001]

Strong 5 to a light 6 at best. Strong 8 at worst.

Agreed- but the bigger impact is that China will be looking for more foreign outlets to channel nationalist focus away from the CCP as a result of these recent events.

I definitely think that foreigners (i.e. ESL teachers) should be immediately thinking of an exit strategy to keep handy on a moment's notice.

@jje100010001 I wouldn't be surprised that once the dam breaks, they say the Marines placed explosives on there to cause the destruction. Or they have footage of Donald Trump doing said action on video.

This was posted earlier. It's supposed to be the layout of the outlets.

Trying to analyse AI upscaled photos is asking for trouble since it obviously needs to approximate and fill in the blanks through virtual guesswork. Here's something reportedly from Sunday morning, showing 7, not 6 open floodgates:

 

[Niggernerd]

This is completely normal, nothing is wrong.
What we should really be concerned about are the dams along the Columbia river; which are old, unsafe, and cause untold environmental damage. America should have removed them years ago.

Whatcha doing Mr.Lok xin ping?

 

[pwnest injun]

Something to consider is that typical water levels at the reservoir are enough extra weight to cause tectonic activity. With water levels higher than usual, there's an increased risk of earthquakes in the area at a time when the structure is already under massive stress.

You know, if any of them do fail and kill a bunch of people it will rocket up the number of people killed by "green" technology. I remember arguing with someone, years ago, that for all its faults nuclear power has killed far fewer people than say - coal. And of course solar panels, until they are made domestically (and perhaps with different materials) are an environmental disaster.

 

[No Ma'ams Land]

Not to blunt the doomchat, but I recall 4chan sperging in a similar way in 2017 over California's Oroville dam. Similar stress issues and flood gates being opened, I think a town or two was also evacuated. Interesting to follow along, though.

We could shout to them: Nice try fellows for a diversion. Close but no cigar.

This! Btw will they blame Mossad as well?

You didn't follow up on that did you? The DWR was an hour or two from breaching the emergency spillway and punched a 300' deep trench in the main spillway.

 

[Homersexual]

Good video on dam spillways. He also has some other relevant videos.

I remember discussion of the emergency spillway, and the conversation petering off once the water levels stabilized. Not saying it wasn't a dangerous event, but I'm not at the level of "inevitable failure" for 3GD just yet.

China blasts dam to release floodwaters as death toll rises

Authorities in central China blasted a dam Sunday to release surging waters behind it amid widespread flooding across the country that has claimed scores of lives. State broadcaster CCTV reported the dam on the Chuhe River in Anhui province was destroyed with explosives early Sunday morning...

China is officially saying "the flood is safely past" https://twitter.com/XHNews/status/1285216832220098561

I have no idea what to make of that.

 

[Super-Chevy454]

It's hard to know how much we can trust China Xinhua News since it's Chinese government owned the same could be said with that video from New China TV. Even various Youtubers who commented on that video have some scepticism.
