At 50 stories high and with a span of more than a mile, one of the world’s largest feats of modern engineering is not a skyscraper. It’s a hydroelectric dam.
The Three Gorges Dam in Hubei Province, China, can hold back more than five trillion gallons (19 billion cubic meters) of water, according to NASA.
At 1.4 miles wide (2.3 kilometers) and 630 feet (192 meters) high, Three Gorges Dam is the largest hydroelectric dam in the world, according to International Water Power & Dam Construction magazine.
Three Gorges impounds the Yangtze River about 1,000 miles (1,610 km) west of Shanghai. It’s named for its location near the three gorges at the foot of the western Wu Shan Mountains, according to PBS.
