Highest Dam in the World – Top 10 highest dam in the world

Highest Dam in the World – Top 10 highest dam in the world The tallest dam ever is currently being built in Tajikistan, the Rogun Dam, which is supposed to be 335 meters (1,099 feet) high. When complete, the dam will be taller than the world’s tallest dam, the Jinping-I Dam in China (305 meters) and the Nurek Dam in Tajikistan (300 meters).

Key Tallest Dams Worldwide:

Rogun Dam (Tajikistan): 335 meters (uncompleted).

The Jinping-I Dam (China, 305 m; arch dam)

Nurek Dam (Tajikistan) – 300 meters (embankment dam)

Xiaowan Dam (China): 292 meters.

Xiluodu Dam (China): 285.5 meters.

Tehri Dam (India): 260.5 meters.

The Rogun Dam project along the Vakhsh River was started in 1976 in the Soviet era and is being finalised as a way to substantially increase energy production capacity in central Asia.

The Top 5 Highest Dams

While the Jinping-I Dam in China currently stands as the tallest dam in the world, it is anticipated to be eclipsed in height by the Rogun Dam in Tajikistan, which is still under construction and could reach new heights in 2026.

Key Highlights for 2026

New King: Rogun Dam, Tajikistan (the heart of Central Asia’s energy strategy) When fully built (the early 2030s), it will be the highest man-made dam in the world at 335 meters. By 2026 construction is well underway, and has begun redrawing the balance of power in the region.

World’s 4th Tallest: The Tehri Dam in Uttarakhand was the tallest dam in India and the fourth tallest in the world at 260.5 meters (855 ft). This is huge earth and rock-fill dam on the River Bhagirathi.

China in the Lead: 4 out of 5 of the Highest Dams Currently in Use It is all part of its ambitious push into hydro to satisfy huge local energy requirements.

The “Natural” Giant: Usoi Dam in Tajikistan — While not a human structure, the Usoi Dam in Tajikistan is officially the tallest dam in the world. Built to a height of about 567 meters (1851 ft), it was formed by a large landslide in 1911, but the dam has not been used for power generation.

F&Q: Common Misconceptions

Q1: Is Three Gorges Dam the tallest?

No. Although the dam is the most potent in the world by electricity generation and one of the biggest by volume, its height is only 181m (594ft). It’s further down the “tallest” list.

Q2: How does it compare to the Hoover Dam?

Hoover Dam — While impressive in its own right, Hoover may once have set records for height, but when compared to large dams built during the last decade, it doesn’t measure up. That is ~114 meters shorter than the Rogun Dam at 221m (726ft).

Q3: Is anyone planning to build a higher dam?

Q: Has China ever proposed the Yarlung Tsangpo (Medog) project in Tibet? Though its precise structural height remains open to engineering debate, its power capacity is believed to be three times the Three Gorges dam.

Top 10 highest dam in the world

The vast majority of the world’s tallest dams are in China and Tajikistan, with the world’s tallest completed dam being the 305 m (1,001 ft) Jinping-I Dam in China. Rogun Dam, a dam under construction in Tajikistan, would be the tallest at an initial height of 335 m.

Following are the 10 tallest dams in the world by height.

1. Rogun Dam (Tajikistan): ~335 m (under construction/ partial embroilment)
2. Jinping-I Dam (China): 305 meters.
3. Nurek Dam (Tajikistan): 300 meters.
4. Lianghekou Dam (China): 295 meters.
5. Xiaowan Dam (China): 292 meters.
6. Baihetan Dam (China): 289 meters.
7. Xiluodu Dam (China): 285.5 meters.
8. Grande Dixence Dam (Switzerland): 285 m
9. Enguri Dam (Georgia): 271.5 meters.
10. Nuozhadu Dam (China): 261.5 meters.

Marginal note: The various lists appear to differ by including either dams that are partially operable or fully under construction (for instance Rogun).

A Quick Look at Top 5 Reaching Finished Dams :

1. Jinping-I Dam (China) 305m (Concrete Arch)
2. Nurek Dam (Tajikistan): 300m (Embankment/Earth-fill)
3. Lianghekou Dam (China) — 295m (Embankment/Concrete-face rock-fill)
4. Xiaowan Dam 292m (Concrete Arch) approx year of completion: (China)
5. Baihetan Dam (China): 289m (Concrete Arch)

They are essential for hydroelectric power generation, flood control, and water regulation.

The 10 Highest Dams in the World

Key Takeaways

The Rogun Milestone: Rogun dam (the tallest man-made dam) It started producing some power years ago, but now standing at over 305m it has exceeded the Jinping-I in height and approaches its designed height of 335m.

India’s position: The Tehri Dam in Uttarakhand remains top 10 worldwide It still supplies a crucial portion of hydroelectric power and drinking water for the northern belt, including Delhi.

Diverse Structures: This includes the Arch dam (Jinping-I), which uses a curved design to transfer the force of water onto the canyon land, as well as the Embankment dam (Nurek and Rogun), which consists of earth and rock walls.

The Quiet Giant: One item in the Top 10 list is a former giant — the Vajont Dam (Rank 9) is not generating anymore. The dam was still there after a catastrophic landslide in 1963, but the reservoir was never re-filled, creating one of the highest “abandoned” structures on Earth.

F&Q: Height vs. Volume

Is the biggest dam the highest one? — Q. No.

China’s Three Gorges Dam, the largest in the world by power capacity and concrete volume, is only 181 meters high, almost 150 meters shorter than the Rogun.

Q: What is the “Usoi Dam”?

The Usoi Dam in Tajikistan, frequently referred to in geography classes, is a natural dam formed by a landslide set off by an earthquake. It is the tallest man-made dam as a science but isn’t truly measurable for what it is constructed.
