If you flip it upside down, it’ll end badly.

Right now, thousands of Chinese are heading to Tibet in trucks.

The president gave them a special mission to block the three biggest rivers in the area.

Last time, they allegedly triggered hundreds of earthquakes and even slightly slowed the Earth’s rotation.

But this time, it’s a whole different level.

A colossal thing, the ultimate symbol of engineering overkill, just the way we like it.

Not sure what’s going on? Me neither.

And if everything goes according to plan, by 2023, the Yarlong Sangpo River will have a new hydroelect electric plant, the largest in the world.

They’re building all of this in Tibet.

And it’s not just some random mountain region.

This is where a huge number of rivers began.

Three of Asia’s longest rivers start here.

The Yellow River, the Yang Sea, and the Mikong, plus tens of thousands of glaciers, plus the altitude and the climate.

Together, it all functions like a giant water tower that stores water and then releases it slowly over time.

That’s why the Tibetan plateau is called the third pole.

Its ice fields are the largest store of fresh water on Earth outside the Arctic and Antarctica.

In summer, the ice melts in the river swell.

In winter, they’re sustained by the steady runoff from the mountains.

The result is powerful, reliable rivers where you can build dozens, even hundreds of hydro power plants.

And the potential really is massive.

These glaciers feed rivers that more than 1.

3 billion people across 10 countries depend on for drinking water, irrigation, and electricity.

Put into numbers, the region’s theoretical hydro power potential is about 210 gawatt, and around 140 gawatt of that could realistically be put to use.

For context, the total installed generating capacity of all power plants worldwide is about 8,890 gawatt.

So the Tibetan plateau alone could in theory cover roughly 2.

4% of global electricity needs.

In plain terms, that’s enough energy for about three Polands or around 80% of Germany.

And so far, very little of it has been developed.

In China’s part of Tibet, only about 1.

7% of the hydro power potential has been tapped.

So there’s a huge open field there.

Plenty more than can be built, rolled out, and connected.

which is exactly why China’s going allin on Tibetan hydro power.

Since 2000, the country has launched 193 hydro power projects in the region and roughly 60% of them are still in the planning or early preparation stage.

China is basically the world champion of dams.

They built more dams than anyone else.

Every dot on this map is a dam.

It all comes down to the elevation change.

Over a stretch of just 31 mi, the river plunges by roughly 6,500 ft.

Locals even nicknamed this spot the Great Bend.

And with a drop like that, you can squeeze out staggering amounts of hydro power.

We’re talking about the Yarlong Sangpo.

It’s one of the highest altitude rivers on Earth, beginning at the Ang Glacier in Tibet, then flowing into India, where it becomes the Brahmaputra.

Along the way, it slices through one of the deepest canyons on the planet.

About 19,714 ft at its deepest point.

The canyon runs for a little over 310 mi.

The scales almost beyond comprehension.

 

Picture the Grand Canyon, only three times deeper.

In total, the Yarlong Sangpo drops around 25,150 ft from its upper reaches to where it exits into India.

That’s why it’s considered one of the most energy richch rivers in the world.

And one specific section near Namsha Barwa, that same 31 mile stretch with a 6,500 footfall, looks like a near perfect site for a hydro power plant.

From an engineering standpoint, this is pure madness.

Seriously, just think about it.

To build a dam here, they’d have to carve multiple tunnels, each roughly 12 mi long, to divert the river.

The flow rate is around 528,000 gallons, about one Olympic pool every second.

Just try to picture that volume of water.

A place like this is a dream for any engineer who’s ever wanted to build the ultimate hydro power project.

So, it’s no surprise that China is looking at this remote, brutal corner of Tibet to take on one of the most monumental dam projects in history.

Not just for China, but for humanity as a whole.

And it’s important to note this wouldn’t be a typical hydro power plant like the ones we’re used to.

Yes, on paper the river still gets blocked by a dam.

That’s standard.

But then things get interesting.

To ring every last bit of power from the elevation drop, they’re planning to drill straight into the mountains.

The core engineering concept of the Midog hydro power station is a set of tunnels, each running for dozens of miles drilled straight through the Yarlong Sangpo River’s Great Bend.

And these aren’t just long bores.

They’re designed for a vertical drop of more than 6,500 ft.

Essentially, the project aims to set new world records for both tunnel length and depth.

They’ll even surpass the current record holders, the Jingping 2 hydropower tunnels in Sichuan Province.

But there’s a catch.

These tunnels would have to pass through fault zones, heavily fractured rock, and an extremely complex stress field in the mountains.

The deeper the excavation, the greater the risks, rock burst, deformation, and weaker rock, and truly extreme rock pressure at those depths.

The plan calls for four to six tunnels, each about 12 mi long, plus diverting roughly half of the river’s flow.

From there, the water is routed down through these tunnels, accelerating and building pressure before it finally hits the turbines.

This approach makes it possible to exploit the height difference to the fullest and extract nearly everything the water can deliver.

That’s why this project looks very different from the kind of power plants we’re used to.

China describes it as a run of river hydro power plant.

The water’s diverted to generate electricity and then return to the Yarlong Sangpo.

Unlike classic dams with massive reservoirs, these systems don’t hold on to huge volumes of water for years or tightly control the river’s flow.

There aren’t any hard technical specs for the project yet because they haven’t been published.

But Chinese state media are already putting numbers on it and they sound almost unreal.

Around 60,000 megawatts of generating capacity.

That’s nearly 30 times the output of the Hoover Dam.

Right now, the world record belongs to the Three Gorges Dam on the Yangy.

in both installed capacity and annual generation, it’s still in a league of its own, producing roughly 95 to 112 terowatt hours of electricity a year.

And if the Yarlong Sang Poe project is actually completed, it could beat that record by almost threefold.

To put the scale into perspective, the largest hydroelectric plant in the US on the Columbia River in Washington State, generates about 20 terowatt hours per year.

And the dam on the Nevada Arizona border, the Hoover Dam, puts out even less, about 4.

2 terowatt hours a year.

And all of this costs an absolutely insane amount of money.

By the latest estimates, a new hydro power plant could run to over 1 trillion yuan, roughly $137 billion.

To grasp the scale, let’s put that into perspective.

$137 billion is about Uspekiststan’s entire annual GDP.

The total value of all goods and services the country produces in a year.

So yes, the price tag for a single dam is basically the size of a whole nation’s economy for 12 months.

And that’s not even the ceiling.

That figure is higher than the yearly GDP of Bulgaria, Slovenia, Cameroon, or Tunisia.

And honestly, you could keep going for a long time.

Over a 100 countries have a yearly GDP smaller than that.

Oh, don’t forget that building in a place like this is risky business.

Not something everyone can handle.

Tibet with its towering mountains exists because the Indian tectonic plate collided with the Eurasian one.

And the worst part is those plates are still moving, which is why this region is considered one of the most earthquake prone on Earth.

Yes, China already has experience building dams on the middle reaches of the Yarlong Sangpo.

But a mega dam on the lower reaches, especially near the Great Bend, is a completely different level of challenge.

This isn’t relatively calm terrain at moderate elevations.

It’s a river that plunges into one of the deepest and most geologically unstable gorges in the world.

This stretch is constantly threatened by landslides, powerful earthquakes, and extreme weather.

All of that sharply increases both the risks and the cost of construction.

And the bigger danger here is seismic activity.

Midog County, the proposed site for the project was hit by the 1950 Assam Tibet earthquake of magnitude 8.

7.

Nepal’s 2015 quake with a magnitude of 8.

1 was yet another reminder of how extremely high the earthquake risk is across the whole Himalayan belt.

By the way, the last major earthquake here happened quite recently in January 2025.

More than 120 people were killed and the tremors were felt across the entire Himalayan region in Nepal, Bhutan and parts of northern India.

The aftermath was severe.

Over 27,000 buildings were damaged and another 3,612 homes simply collapsed.

In some villages, 80 to 90% of all houses were destroyed.

Inspections of five hydroelectric plants revealed cracks.

Three of them had to be drained.

And at one dam in Tangri County, the wall had tilted so badly that about 1,500 people were urgently evacuated from six villages.

And that’s only part of the problem.

People have to work in the cold with a constant lack of oxygen.

The altitude really hits you here.

The catch is the problem isn’t up there, it’s down below.

Since the rock lies so far down, the project runs into an additional challenge.

High geothermal temperatures.

In short, the working environment is extreme from every angle, a direct threat to both the machinery and people’s health, and there are risks for the tunnels themselves, too.

The structure could become unstable, and construction materials could wear out faster.

One small mistake, and you’re looking at losses in the billions.

Plus, the site is extremely remote.

Until fairly recently, there were no decent roads here, and the power supply was unreliable.

Midog County, home to only about 15,000 people, was the last county in China to be connected to the national road network.

The first road didn’t reach it until 2013.

Yes, there’s some experience already, but it isn’t very encouraging.

When a small hydro power station was built in Midog in 2013 to 2015, it ended up costing four times more than comparable projects elsewhere in China.

The reason, simple, logistics.

For more than 200 days a year, there are heavy rains and landslides and mud flows happen regularly.

Yes, over the past decade, the government has invested roughly $16.

8 million.

And the length of paved roads in Midog is more than doubled.

But even with that, transporting oversized equipment for a truly large-scale project is still a separate headache and honestly, one of the biggest.

I’d even call it a full-blown migraine.

Just as a reminder, construction officially began on July 19th, 2025, and they’re planning to start using the whole thing in 2033.

There’s one more sudden complication.

The river they want to dam belong to China alone.

It keeps flowing into India.

The Yarlang Sangpo rises in western Tibet near the Ang Glacier.

From there, it runs east across the Tibetan plateau, then makes a sharp turn to the southwest where it becomes part of the Brahmautucha system.

The name, as you might guess, is Indian because downstream, the river passes through northeastern India and Bangladesh.

On maps, it often looks like one very long line, but in reality, it’s a vast river system.

By discharge, it ranks ninth in the world, and by length, it’s 15th.

For the region, it’s a true lifeline.

Irrigation, transport, drinking water for millions, everything depends on it.

Yes, the tunnels and the dam are being designed with seismic activity in mind, but there are no guarantees.

If a strong enough earthquake damages the structure, debris and water will rush downstream straight into India.

And that isn’t even the worst case scenario.

The real danger begins after the dam is built.

When the dam is holding back water, a huge reservoir, if the structure fails and can’t hold the Yarlong Sang Poe, an enormous wall of water will tear downstream with staggering force and then it’ll trigger destruction on a scale that’s hard to even picture.

It’s hardly surprising that the reaction in India was harsh.

Politicians said the project could give China a way to use so-called water bombs in any future conflict, releasing massive volumes of water across the border.

In India, people have already started talking about building their own dam downstream.

Experts are warning, however, that the environmental damage from such a project may be no better.

Puandu, the chief minister of Aronakal Pradesh, the state directly downstream, called the project a direct threat.

He said that during routine operations, the river in the state could simply run dry.

In the worst case scenario, the dam could be used as a tool to trigger flooding that could claim the lives of hundreds of thousands.

Some independent experts share these concerns.

In a report, an Oxford University political scientist wrote bluntly that building dams on Tibetan rivers effectively gives China leverage over India’s economy.

But there are also more restrained assessments.

For example, an environmental historian at Australia’s Lrobe University argues that despite the project’s energy potential, dams like these wouldn’t be able to hold back such enormous volumes of water for long.

Still, from New Delhi’s perspective, even a shift in the river’s flow is a serious concern.

It could disrupt the Yarlong Sangpo’s natural rhythm, affect groundwater and surface water levels, and hit both agriculture and drinking water supplies.

There are also lingering questions about water quality.

From there, the consequences cascade to the communities along the river for whom it’s a source of water, food, and a means of making a living.

China, for its part, insists India has nothing to worry about.

Yeah, right.

Just a massive dam that’s going to change literally everything.

All right, jokes aside, there are real arguments on the table.

Yes, a hydrop power project could affect river flows in India’s Aronakal Pradesh, but at least in theory, it shouldn’t have a major impact on the Brahmautra.

Overall, studies paint an interesting picture.

Even though roughly half of the river basin technically lies within China, that portion accounts for only a small share of the total discharge.

Depending on the estimate, water originating in China contributes around 30% of the Brumopatra’s flow.

Some sources put it much closer to 7%.

Most of the waters generated downstream in India thanks to monsoon rains and numerous tributaries, snow melt and glaciers in the upper Tibetan reaches contribute about a quarter of the total flow, no more than that.

Given this hydraological balance, the assumption is that upstream infrastructure like the Midog hydro power project would only have a limited effect on water levels further down the river.

At least that’s how Beijing puts it.

But even 30% is enormous.

That’s a huge amount of water passing through a huge valve.

I honestly can’t even picture the scale because we’re talking volumes that are just hard to grasp.

During the dry season, especially when the monsoon is laid and the Chinese stretch becomes far more important, glaciers melt faster.

And if the flow is held back at that moment, things could get very uncomfortable for India.

Imagine a drought year.

The rains don’t come and the river inside the country shrinks dramatically and then upstream someone decides not to release water.

Fields are left without irrigation and cities start facing disruptions in drinking water supply.

So, even if that so-called Chinese share dropped by just 10%, it could be enough to trigger localized crisis in some Indian states.

And the thing is, China and India simply don’t have a water sharing treaty.

No clear rules about who gets how much, when, or under what conditions.

What’s more, China has no such agreements with any of the 13 countries it borders.

There’s also a different opinion.

According to it, the dam might not harm India at all.

It could actually help simply because less water would mean weaker floods.

Even Assam’s chief minister Hamont Biswis Sarma has said that a reduction in the Brahmautuch’s flow from the Chinese side could benefit the state and soften the impact of the yearly destructive flooding.

The contrast is immense.

The Tibetan plateau gets about 12 in of rainfall a year while the southern part of the basin in India averages over 90 in.

The monsoon is what really drives the river.

It arrives from June through September and rapidly drives up the volume of runoff.

A good example is the 2012 flood.

It was unprecedented and it was caused specifically by monsoon rains in India, Bangladesh, and Myanmar.

That year, 124 people died and around 6 million were forced to leave their homes.

In 2015, the river’s floods killed 42 people, triggered landslides, cut off roads, and affected 1.

65 million residents across 21 districts.

About 2100 villages went underwater and crops were destroyed across 440,000 acres.

In 2016, it happened again.

Flooding affected 1.

8 million people.

28 people died and nearly 494,000 acres of farmland ended up underwater.

I won’t go on.

I think the point is clear by now.

There were floods in 2017, in 2018, and then almost every year after that.

So maybe in this particular place having a bit less water in the river isn’t actually such a bad thing.

So why did China take so long to get this construction going? I looked into it and it turns out there are two main reasons.

The first is simple but important.

For a long time, the construction site was extremely remote.

Until fairly recently, there were no proper roads and no reliable electricity.

So launching a project on this scale just didn’t make sense.

The second reason is political.

In the past, Beijing probably wasn’t ready to deal with potential disputes with downstream countries, above all India.

But now things look different.

China clearly feels more confident and seems to believe it can handle outside pressure.

That’s what’s allowing the project to move forward.

And what can India do about it? Well, to be honest, not much.

In theory, it can keep the dialogue going, develop its own water management projects, and strengthen hydro power and water infrastructure in the Himalayan foothills.

That sounds reasonable, but in practice, it’s much harder.

Every project like that costs a fortune.

And then there are protests from environmental groups warning about the destruction of some of the last truly wild areas.

And don’t forget about farmers who worry about their water, their land, and their future.

One project like this has already got everyone talking.

Well, maybe not everyone, but people in India for sure.

It’s the Upper Ciang Hydro Power Dam.

They’re planning to build it near the China India border on the same Yarlong Sangpo Brahmautapucha River system.

Once completed, its reservoir is expected to hold about 2.

4 trillion gallons of water.

The goal is to start building around 2028 and have the station operating by 2032.

India says the dam could in a way offset China’s hydro power project upstream by holding back water and preventing a potentially destructive surge from being released downstream.

Our produce chief minister PMandu has called it a defensive measure.

He says it’s protection against any water related threats from the Midog project which he even described as a ticking time bomb.

Can we put that in really simple terms? If too much water gets dumped from upstream or if an earthquake damages the dam, the surge wouldn’t roar straight down the river.

It would hit another reservoir first, reducing the risk of disaster further downstream.

Power would be a good bonus.

The Indian Dam could generate 11,200 to 11,600 megawatt, making it the most powerful hydro power plant in the country.

That would also help cut India’s reliance on coal.

The problem is that the dam would flood 27 villages and force more than 150,000 members of the Audi people to relocate.

It would also damage forests, farmland, and culturally important sites.

And for this region, that’s a huge deal.

The Audi people consider the river sacred.

They depend on it for everything.

fertile soil, orange and jackf fruit orchards, and the life they’ve always known.

Their fear is simple and completely understandable.

The dam would literally flood their world.

But judging by India’s actions, the country doesn’t seem ready to abandon the project.

It’s already built two major dams despite local opposition.

So, the logic is clear.

Energy and security outweigh everything else.

Hold on.

How many people would be affected by the Chinese project? No one’s giving exact numbers yet, but relocation there also looks unavoidable.

For context, the three gorgeous project displaced about 1.

4 million people.

Midog is much less densely populated, and they say they’re not planning a classic reservoir, so the scale could be smaller, but that doesn’t mean there won’t be serious consequences.

The project’s expansion threatens culturally significant places in one of the most sacred regions for Tibetans.

According to the International Campaign for Tibet, if all 193 projects in the area go ahead, more than 1.

2 million people could be affected by relocation and dozens of religious and sacred sites would be put at risk.

There’s one more important point I still haven’t mentioned.

Right at the very end of its journey, the river runs through Bangladesh.

We won’t get too deep into the details.

Down there, it’s joined by other rivers, splits into multiple channels, and in places even changes names.

Bottom line, all that water eventually ends up in the Bay of Bengal.

According to a 2022 estimate by Bangladesh’s Ministry of Environment, even a 5% reduction in the Brahmautra’s flow could cut agricultural output by as much as 15% in certain regions.

And that’s a direct threat to food security.

Still, there’s no real consensus.

Some water experts and activists in Bangladesh argue the proposed dam won’t have any noticeable negative impact downstream toward the country.

Want to know why? because the dam’s simply too far away.

In their view, after the water is traveled more than 600 miles from Aronakal Pradesh, its flow patterns and quality would have time to recover by the time the river reaches Bangladesh.

So, they say everything will be fine.
