The Height of Hoover Dam

The Hoover Dam stands at an impressive 726.4 feet, making it taller than two of the Great Pyramids of Giza stacked on top of each other!

The dam’s height was critical in creating the largest reservoir in the United States, Lake Mead, which stretches for 110 miles behind the dam and holds a whopping 28.9 million acre-feet of water when at full capacity. That’s enough water to cover the entire state of Pennsylvania with over 1 foot of water!

Engineering Marvel

During its construction, the Hoover Dam was the tallest dam in the world and still remains an engineering marvel today. The dam was built between 1931 and 1936 during the Great Depression, providing thousands of jobs to workers in need.

The engineering feat of building such a colossal structure, which required diverting the Colorado River, was made even more impressive by the fact that the dam was constructed using only 230 concrete blocks, each uniquely shaped to fit into the curve of the dam.

Tourist Attraction

Today, the Hoover Dam is not only a crucial source of hydroelectric power and water for the Southwestern United States but also a popular tourist destination. Visitors can take guided tours of the dam, learn about its history and operations in the visitor center, and even stand on the dam to marvel at its sheer size and the stunning views of the Colorado River and Lake Mead below.
