China has built over 98,000 dams, but in just five years, it lost nearly 4,000—along with 80% of its flood-control capacity. Why? These dams prioritize hydropower, fish farming, and tourism over flood prevention. Take Beijing's Miyun Reservoir: overfilled from the South-to-North Water Diversion Project, it hit record levels before a storm, forcing a massive discharge that caused devastating floods. Built during the Great Leap Forward with poor quality, Miyun now poses a huge risk. Is this a failure of engineering or CCP priorities?
Now, China has more dams than any other
country in the world. In fact, half of
the world's reservoirs are in China. And
six of the 10 tallest dams are in China,
too. And before the Communist Party came
to power in 1949, China had only about
20 reservoirs. They were mostly built by
the Japanese during their occupation.
And then by 1950, there were just 22
dams in China. That's a very small slice
out of the 5,268
dams worldwide. So, China only had 22
out of them. By 1973, just in two
decades, China had constructed 170,000
dams, but they're mostly small ones. And
a second wave began after the three
gorgeous dam were approved. Um, then
China started to focus on mega dams and
giant reservoirs. And then since 2000,
China has doubled its reservoir
capacity, adding over 470 billion cubic
meters. By the end of 2020, China had
Yeah. 98,566
dams and reservoirs uh with a combined
storage capacity of 930 or 931 billion
cubic meters. So you see between the
year 1973 and 2000 the number of dams
were reduced but the capacity increased
significantly. But if you look carefully
in 2025
during the national people's congress
water resource minister Lee Guing
revealed some stunning numbers. He said
that in 2025 China has 94,800
77 dams. And if you compare that number
to the number five years ago, China lost
3,689
dams in just 5 years. And that's for 4%
of the total. And that doesn't even
account for the newly built dams,
meaning the real loss could be even
greater. What's even more alarming if
you look at the numbers, flood control
storage capacity dropped to 185.6
cubic meters and that's 15th of what it
was in 2020. So in 2020, China's total
flot control storage capacity was 930
and then it's been dropped to just oneif
of that in five years. So here's the
question. How did China lose 4% of its
dams but 80% of its flood control
capacity in five years? That's the
question raised by uh one of China's top
hydraologist, Mr. Wi, who now lives in
Germany. Now, if you think about it,
China has been building larger and
larger dams. If anything, they should
increase the flood control capacity.
They might get rid of some older dams
and replace them with the newer ones,
but the newer ones are at much higher
capacity. So, it's understandable that
there the total number of dams is
reducing, but the total capacity flood
control capacity shouldn't be even when
they replace the old dams with new ones
because the new ones are mega mega dams.
If you really think about it, the answer
there's only just one answer in my
opinion because those dams were never
used for flood control in the first
place. These dams were meant to manage
flood control, power generation,
irrigation, transport and tourism. But
most of them have been used for economic
gain uh for hydropower, fish farms and
tourism. That's why even though China
has been building many dams and
increasing capacity, the country has
been losing flood management capacity.
Dams are supposed to release water
before flood season so they can store
water during floods. But in China, local
governments often refuse to release
water in dry seasons because they don't
want to lose the economic benefits. So
they gamble. If it doesn't rain much,
they're fine. But if heavy rain comes,
they're forced to suddenly discharge
massive volumes downstream, turning what
could have been a manageable flood into
a man-made disaster. And these dams have
become ticking time bombs, poorly
maintained, mismanaged, and dangerously
operated. And they turn annual flood
seasons into fullblown crisis. And now
let's back to that 4% dam loss figure.
It's likely worse. uh once you subtract
the newly added dams, the actual loss of
old dams could be much higher. So what
happened to those thousands of dams that
were gone? Some experts believe that the
3689 dams lost between 2020 and 2025
either collapsed or failed during poor
construction and age and poor
maintenance. If true that number is
higher than all dam collapses recorded
over 67 years. So um let me give you
some numbers. So accord this is public
information from the year 1952 to 2021.
So in a span of 67 years China
officially recorded 33,558
dam collapses.
That's an average of 52 dams collapses
per year with a failure rate of 5.3 per
10,000 dams. That's already five times
higher than the international safety
standard of one per 10,000. But think
about it. 3600 dams disappeared in just
5 years versus 3500 dam collapses in 67
years. Where did they go? that number is
problematic. So um that's why the
Chinese hydraologist Mr. Wang he's very
well known he's a this is an expert on
three gorgeous dam. So he calls the
number extremely disturbing. So it
strongly suggests that the number of
dams that have failed in the past five
years is very high is alarmingly high.
Now China has a long history of dam
disasters. In August 1963,
319 dams failed in the High River Basin
in 1973.
10 years later, over 550 dams reportedly
collapsed in a single year. In August
1975,
62 dams, including the Bancha Dam,
collapsed in Hernand province, killing
an estimated 240,000 people and
displaced 11 million. The Discovery
Channel later ranked this dam collapse
uh the number one man-made technological
disaster in world history. And since
Shinjin Ping took office, unannounced
emergency discharges from dams have
become common practice causing floods
every year for the reason I described
above. So now let's talk about the the
devastating flooding in Beijing right
now. It wasn't just the result of heav
he heavy rain. It was largely man-made,
a disaster uh driven by mismanagement of
the Miwing reservoir, which is the
capital city's main water source. Over
the years, the Mi Dam hasn't just been
filling up from its natural sources, the
Chauru and Bhur rivers, but also from
the CCP's so-called south to north water
diversion project. This massive project
moves water uh from the south to the
north. So in this case, in the case of
the Miin reservoir, it moves water from
the Danjango reservoir in southern China
all the way to Beijing using gravity.
And Danjango sits at 170 m above sea
level, which is about 120 meters higher
than Beijing's average elevation. So
thanks to this height difference, water
flows naturally north northbound into
the capital. It made sense, right? But
here's where it gets strange. Very
strange. After reaching Beijing's um
Tuanchan lake, you know, this water from
the south, somehow the Chinese officials
decided to pump that same water, that
same water gets pumped uphill into the
Miwin reservoir. But the problem is the
Ming reservoir is 100 over 100
kilometers away from the city and it's
uphill. It's 133 meters higher than
Beijing. So the Chinese officials built
103 kilometers long system of channels
and pipelines powered by nine pump
stations that pushed this water that
came from the south uphill uh by 133
meters into this muing reservoir. Now so
think about it. The first the water
flows naturally downhill then it's
forced back uphill. So it's kind of
reverse engineering right? But it's
that's how China's GDP keeps growing
through these inefficient wasteful mega
projects. However, the problem just
doesn't I mean if it's just wasteful
it's a minor issue but this has created
a problem that has already become out of
control. So since this reverse transfer
or uphill transfer began in 2015 and
from that point on Min reservoir's water
level or or or um the the water volume
that it holds skyrocketed. In 2013 the
reservoir held just two 800 million
cubic meters of water. That's before the
project. And then by 2018 that number
hit 2.2 billion cubic meters. 2019 it
reached 2.6 billion. 2021 it reached
3.3.6
billion cubic meter and by that year the
water level has reached 155.3
m. That's already dangerously high. And
then in October 2024 it reached 3.58
billion cubic meters. And then on July
29th, 2025,
just before the floods, Mi hit a record
height of 3.61
billion cubic meters with a water level
of 155.52
m. Now, here's the problem. The
reservoir's flood warning level is 150
m. The maximum safety limit during flood
season is 152 meters. The top of the dam
is only 160 m. So by late July, meaning
the reservoir was running 3.5 meters
above its flood season safety limit. So
when the storm hit, officials had no
choice. They had to discharge water
rapidly or risk dam the dam's failure.
But that emergency discharge triggered
downstream flood disaster, destroying
homes, infrastructure, and likely
claiming far more lives than officially
reported. And it gets worse. This dam uh
was Mim Dam, the this very dam that's
responsible for the capital city's water
resources was built during the great
great leap forward period. It was a time
known for poor construction standards.
And during the 1976 Tangan earthquake, a
landslide nearly caused the dam to
collapse. It's said that the main dam is
over 100 meters higher than Teneaman
Square. If it were breached, flood
waters could reach 2 mters deep in
Teneaman Square itself. So in short, uh,
Muin did not do what a reservoir is
supposed to do, mitigate flood risk or
reduce peak runoff. Instead, it released
nearly all the incoming flood water in a
compressed window of time, intensifying
the destruction downstream. So, the real
root of the July flood disaster in
Beijing in suburban lies in years of
overfilling the reservoir with water
from the south to uh from the south to
north diversion project. So officials
treated the rise in water levels as a
political and economic wing because
that's an indication of their local GDP
index.
So they completely ignore the grave
safety risks. When a dam is full to the
brim before flood season even begins,
it's no longer a protective buffer. It
becomes a liability, right? A disaster
waiting to happen. But under the CCP's
rule, there's no accountability and no
respect for human life. The only thing
officials know when disaster strikes is
is to lie and cover
