I should be sleeping and preparing for a new week. Instead I'm LARPing as a journalist since they aren't reporting on this shit.
Okay so I have been grabbing numbers every few hours today. My snapshots aren't always spaced out as well as I would like, but here's a general summary of what today looked like:
(I am using official CCP numbers - Take them with a grain of salt. Even if they are doctored and/or low balled, I guess not even the CCP can polish this turd)
I simply wanted to look at the reservoir water height today since there had been a lot of rain over the weekend. Some of these numbers also include the amount of water flowing into the reservoir, which I will put in parenthesis next to the reservoir height. The times listed are all in Eastern Standard Time; I am not entirely sure why their website does this.
July 26 reservoir water level (and inflow)
10AM: 160.03m (54,000 m³/s)
11AM: 160.06m
3PM: 160.27m
4PM: 160.34m (55,000 m³/s)
8PM: 160.56m (57,000 m³/s)
9PM: 160.63m
10PM: 160.71m (59,000 m³/s)
11PM: 160.77m
12AM: 160.85m (59,500 m³/s)
The day started off with the same slow and steady increase in the reservoir's water level as the prior day. But the major factor between July 25th and July 26th was the rate of water flowing into the reservoir. To illustrate this, here is a data point from the day before:
July 25 reservoir water level (and inflow)
2PM: 158.86m (36,000 m³/s)
On July 25th at 2PM the Three Gorges Dam was releasing water at a rate of 37,500 m³/s which is a good thing. They were putting more water out through the dam than they were taking into the reservoir. Overnight that all changed as the recent storms began to hit the reservoir and the inflow began to skyrocket. Worse, over the course of July 26, there has been a minor but steady
decrease in the amount of water the Three Gorges Dam is releasing. The day started at an outflow rate of 37,500 m³/s, then dropped to 37,400 m³/s until reaching 37,200 m³/s for most of the afternoon all the way up until the most recent reading at 11AM, just before I started writing this post. And I ended up spending so much time on this that you get the midnight readings as well! And yikes they don't look any better.
It is a very minor decrease; however I do not understand why outflow would be reduced at all given the enormous increase in reservoir inflow. What I do know is that the amount of water in the Three Gorges Dam reservoir has begun increasing more rapidly. The rate of inflow is especially alarming given all of the mitigation that the CCP has attempted over the past two weeks. It does not appear as if their efforts are having a long term, sustainable impact.
Today has offered a break in the rain but that ends in mere hours. And within 48 hours there is the potential for 10cm of rain to fall on the region around the dam, followed by days and days of steady rain in the forecast. I'm not sure what else there is to do at this point. Not to be a broken record, but the catastrophic flooding up and down stream is going to be get much worse before it starts to get even a little bit better. The dam is pushing ~37
tonnes of water per second out through its interior and yet the reservoir is taking in ~60 tonnes of water per second. I don't see that reservoir intake water dropping drastically. There may be a slight decrease as today's lack of rain hits in 12-24 hours, but then I would expect that number to jump back up again as the torrential downpours of the following few days make their way downstream.
I'm no good at math. But given the amount of land being rained upon and all of the rivers and tributaries and miscellaneous runoff, the reservoir is four or five days away from being slammed. And there does not appear to be any sign that the CCP will be able to reduce the water level significantly in time to ward off further problems up and down stream. I can't say if this will push the reservoir over its stated limits of 175 meters, but it's going to be a harrowing couple of weeks for people on either side of the Three Gorges Dam.
