Confirmed! During the September 10th period of the Three Gorges Reservoir, the 175-meter water storage stage in 2023 will be initiated.

However, many people have also seen that although there is a lot of rainfall in southern China, there is still a lack of water sources for the entire southern region of China.



On the comprehensive drought monitoring map of China, it can be seen that the middle and lower reaches of the Yangtze River in China - Jiangxi, Hunan, and other places - have also shown a trend of drought.

So, this makes it difficult for many people to understand, that is, in the middle and lower reaches of the Yangtze River in China, there is still drought. Why not increase water release and instead carry out water storage? Let's answer step by step.



The Three Gorges Reservoir starts storing 175 meters of water in 2023!

Firstly, we need to understand the importance of the Three Gorges Reservoir, which is an artificial lake formed after the completion of the Three Gorges hydropower station in China, with a total area of 1084 square kilometers.

To put it bluntly, the Three Gorges Reservoir is a part of China's Three Gorges hydropower station, or rather a part of the entire Three Gorges water conservancy project.



Of course, when it comes to the importance of the Three Gorges Water Control Project, I believe many people should know that it is a project that benefits the country and the people, and its importance cannot be described. Let me briefly explain a few functions.

Firstly, the flood control function of the Three Gorges Water Conservancy Project was that before its construction, various rivers in the upper and lower reaches of the Yangtze River in China often experienced floods, and every time a major flood occurred, flood diversion measures were taken in the Jingzhou section of the Yangtze River below Yichang (Jingjiang), flooding villages and farmland, causing extremely large losses.

After the construction is completed, the huge storage capacity provided by it will enable the downstream Jingjiang area to withstand the once-in-a-century catastrophic flood, and also contribute to the governance of Dongting Lake and the comprehensive repair of Jingjiang embankment.



Secondly, the power generation function of the Three Gorges Water Control Project is something that everyone has experienced. With the drastic changes in climate, we see prolonged high temperatures leading to a shortage of electricity. Without the existence of the Three Gorges Reservoir, many regions may face power outages every summer.

After its construction was completed, it created enormous green energy for our country. According to statistics, 100 billion kilowatt hours of green electricity is equivalent to saving 319 million tons of standard coal and reducing 85.8 million tons of carbon dioxide.

If calculated based on the GDP generated by 12 yuan per kilowatt hour of electricity, 100 billion kilowatt hours of electricity can support China's GDP of 1.2 trillion yuan, so I think it would be good.



Thirdly, the shipping value of the Three Gorges Water Conservancy Project is that before the completion of construction, the one-way annual transportation volume of the Chuanjiang River was only 10 million tons, and ships of 10000 tons could not reach Chongqing at all.

After the construction is completed, this is not a problem.

For example, in the first half of 2023, the Three Gorges Ship Lock operated 5469 times safely, passing over 20000 ships, passing 4929 passengers, and passing 81.48 million tons of cargo, an increase of 9% year-on-year; The ship lift has safely operated a total of 2206 times, passing over 190000 passengers, 2232 ships, and 1.97 million tons of cargo, generating enormous value.



In addition, there are also values such as drought resistance, so the construction of the Three Gorges Reservoir is very good. This is not true. The Three Gorges Reservoir was impounded on September 10th, 2023, and the Ministry of Water Resources has officially approved the "Three Gorges Reservoir 2023 Water Storage Plan".

Previously, the 2023 joint water storage plan for the downstream cascade reservoirs of the Jinsha River had also been launched, which means that the water storage plan for the Yangtze River main stream cascade reservoirs under the jurisdiction of the Three Gorges Group has been fully approved.



However, what many people do not understand is that there are signs of drought in the middle and lower reaches of the Yangtze River in China. Shouldn't we increase water release? Why is it still storing water? This question must be explained.

Why not increase water discharge instead of storing water?

Indeed, it is very difficult for many lakes in the middle and lower reaches of the Yangtze River in China to stop water supply, and there are many periods of low water supply. For example, the largest freshwater lake in China, Poyang Lake, is expected to peak and decline, and will continue to experience low water levels. Dongting Lake may be slightly better, but it is also often in a low water level.



So, we often see many netizens say that China's largest and second largest freshwater lakes may undergo significant changes in the future because climate change is changing everything, which is indeed a fact.

However, if these two freshwater lakes have completely disappeared, it is definitely not a change in China's climate, but rather the entire Earth's climate has entered an extraordinary period. Therefore, take a rational view.

At the same time, I have also seen people say that the drought in the middle and lower reaches of the Yangtze River is a problem with the Three Gorges Reservoir. I believe this issue no longer needs to be discussed and has been discussed multiple times.



If the Three Gorges Reservoir changes the climate issues in the middle and lower reaches of the Yangtze River, and the climate of the entire Earth, as well as the high temperatures, droughts, and other issues in many countries around the world, who should be blamed? So, we should be more rational. This is a change in the climate of our planet, not the Three Gorges Reservoir.

To put it harshly, without the Three Gorges Reservoir, all the water entering the downstream would not have been able to dry out? The Yangtze River is connected to the sea, and without any interception measures, any amount of water will be useless.



Moreover, as mentioned above, if the Three Gorges Reservoir does not carry out drought relief work in recent years, I believe the situation in many areas of the middle and lower reaches of the Yangtze River may be even more difficult.

In extreme weather conditions, the Three Gorges Reservoir has implemented joint water regulation for many areas in the middle and lower reaches of the Yangtze River, which can be said to be very significant. In 2022, the cumulative inflow of water from the Three Gorges Reservoir was 340.4 billion cubic meters, 25% less than the designed multi-year average (451 billion cubic meters).



During the ebb and flow period, the Three Gorges Reservoir fully utilized its role as a freshwater resource reservoir, providing a total of 156 days of downstream water replenishment, with a total replenishment amount of approximately 21.8 billion cubic meters. This is all to alleviate the drought problem in the middle and lower reaches of the Yangtze River.

Of course, this may not include the usual water transportation, and many people mistakenly believe that the Three Gorges Reservoir has not discharged water at any time, which is completely wrong.

If water is not discharged, where is the electricity coming from? You should know this simple truth, so many people have a deep misunderstanding of the Three Gorges Reservoir and hope to understand it.



Why not increase water discharge instead of storing water?

This is actually something that the Three Gorges Reservoir needs to do every year, and the Three Gorges Reservoir stores water at the end of each year's flood season to gradually release and free up its storage capacity from the dry season to the next year's flood season, in order to "store abundant water and replenish depleted water" and provide strong support for the navigation, water supply, ecology, power generation and other needs of the Yangtze River Basin this winter and next spring.



So, in simple terms, it's preparing for the upcoming dry season, which is the normal situation.

summary

Overall, the Three Gorges Reservoir needs to do this every year, and there is a drought in the middle and lower reaches of the Yangtze River, mainly due to climate change. Many people have a deep misunderstanding of the Three Gorges Reservoir. It is really necessary to understand and not be misled.



If the Three Gorges project has the ability to change the global climate, I would like to make some changes.

And lakes such as Poyang Lake and Dongting Lake already have their own water systems, which is the main issue. If there are no water systems, lakes cannot store water, and no amount of water can stay for a long time.
