Located on the Vakhsh River in Tajikistan, the Nurek Dam is the tallest dam in the world, standing an astounding 1,817 feet tall.  Constructed between 1961 and 1980, this earth-fill embankment dam has transformed the surrounding region by creating a massive reservoir that supplies water for irrigation and hydroelectric power.

The dam’s nine turbines generate 3,015 megawatts of power, making it a vital energy source for Tajikistan.  Its creation submerged numerous villages, prompting the relocation of thousands of residents, an event that remains etched in the history of the region.  Today, the turquoise waters of the reservoir provide a stunning backdrop, attracting tourists and photographers from around the globe.

#2: Jinping-I Dam – 1,837 feet

Nestled in the Sichuan Province of China, the Jinping-I Dam reaches a height of 1,837 feet, making it the tallest arch dam in the world.  Built between 2005 and 2014 on the Yalong River, this engineering feat helps regulate water flow and generate hydroelectric power.

The dam’s innovative double-curvature design allows it to withstand immense water pressure while maintaining stability.  Its reservoir holds a staggering 7.76 billion cubic feet of water, supporting irrigation and flood control.  Anecdotal tales from the construction period highlight the challenges faced by workers, including harsh terrain and adverse weather conditions, underscoring the immense effort required to complete this project.

#3: Rogun Dam – 1,817 feet

The Rogun Dam, currently under construction in Tajikistan, is poised to match the height of the Nurek Dam at 1,817 feet.  Situated upstream of the Vakhsh River, this dam is set to become a cornerstone of Tajikistan’s energy infrastructure, with a planned capacity of 3,600 megawatts.

Once completed, the Rogun Dam will mitigate water shortages and enhance regional energy stability.  Its construction has been a long and arduous journey, marked by delays and geopolitical challenges.  The dam represents a symbol of national pride and a beacon of hope for a sustainable energy future.

#4: Xiaowan Dam – 958 feet

The Xiaowan Dam in China’s Yunnan Province stands at 958 feet and is a paragon of modern engineering.  Completed in 2010, this arch dam on the Lancang (Mekong) River generates 4,200 megawatts of power, ranking among the top hydroelectric projects globally.

The dam’s striking arch design blends harmoniously with the surrounding mountains, creating a picturesque landscape.  Its construction involved cutting-edge technology and meticulous planning to ensure seismic safety in this earthquake-prone region.

#5: Grande Dixence Dam – 935 feet

Switzerland’s Grande Dixence Dam, at 935 feet, is the tallest gravity dam in the world.  Built between 1951 and 1965, it holds back the Lac des Dix reservoir, which stores water from 35 glaciers.

This engineering marvel provides hydroelectric power to millions while showcasing Switzerland’s commitment to sustainable energy.  Anecdotal stories from the dam’s construction highlight the ingenuity of the workers who overcame harsh alpine conditions to complete the project.

#6: Inguri Dam – 892 feet

Situated on the Inguri River in Georgia, the Inguri Dam stands at 892 feet and ranks as one of the tallest concrete arch dams in the world.  Built between 1961 and 1987, it produces over 1,300 megawatts of power, supplying energy to Georgia and neighboring regions.

The dam’s construction united diverse engineering teams during the Soviet era, symbolizing collaboration despite geopolitical tensions.  Its sweeping arch and serene reservoir have become a symbol of resilience and innovation.

#7: Vajont Dam – 859 feet

Located in northern Italy, the Vajont Dam rises to a height of 859 feet and holds a tragic history.  Built in 1960, the dam’s reservoir caused a massive landslide in 1963, resulting in a devastating flood that claimed thousands of lives.

Despite its tragic past, the Vajont Dam stands as a cautionary tale, reminding engineers of the importance of studying geological conditions.  Today, it remains a somber monument to human ambition and the forces of nature.

#8: Hoover Dam – 726 feet

One of the most iconic dams in the world, the Hoover Dam on the Colorado River stands at 726 feet.  Completed in 1936, this gravity-arch dam was a groundbreaking achievement for its time and continues to provide power, water, and flood control to the southwestern United States.

The dam’s Art Deco design and massive structure attract millions of visitors each year.  Anecdotal tales from its construction highlight the courage of the workers who braved extreme conditions to build this symbol of American progress.

#9: Oroville Dam – 770 feet

The Oroville Dam in California, standing at 770 feet, is the tallest dam in the United States.  Built between 1961 and 1968, this earth-fill embankment dam creates Lake Oroville, a vital water reservoir for irrigation and drinking water.

In 2017, the dam made headlines when its spillway was damaged, leading to the evacuation of thousands.  The subsequent repairs highlighted the importance of infrastructure maintenance in preserving safety and functionality.

#10: Tehri Dam – 857 feet

India’s Tehri Dam, at 857 feet, is the tallest dam in the country.  Located on the Bhagirathi River, this multi-purpose dam generates 1,000 megawatts of power and provides irrigation and drinking water to millions.

The dam’s construction faced significant opposition from environmentalists and local communities, who raised concerns about its ecological and social impact.  Despite these challenges, the Tehri Dam stands as a confirmation to India’s efforts in energy generation and water management.

The tallest dams in the world are more than feats of engineering; they are monuments to human ingenuity and resilience.  From providing energy and water to serving as cautionary tales of nature’s power, these structures play pivotal roles in shaping modern civilization.  Each dam tells a story of ambition, challenges, and the delicate balance between progress and preservation, standing as a confirmation to humanity’s ability to reshape the world.
