Geographical Facts About Hoover Dam

Here are some geographical facts about Hoover Dam:

  1. Location: Hoover Dam is situated on the border between the U.S. states of Nevada and Arizona. It straddles the Colorado River, which serves as the boundary between these two states.
  2. Colorado River: The dam impounds the Colorado River, creating Lake Mead, the largest reservoir in the United States by maximum water capacity. Lake Mead stretches approximately 112 miles (180 kilometers) upstream from the dam and covers about 247 square miles (640 square kilometers) when full.  
  3. Mohave Desert: The region surrounding Hoover Dam is part of the Mohave Desert, a desert in the southwestern United States. The dam’s construction brought significant challenges due to the harsh desert climate, with extreme heat in the summer and cold winters. Unique Facts About Hoover Dam - Hoover dam facts

  5. Elevation: Hoover Dam sits approximately 726 feet (221 meters) above sea level. The high elevation contributes to its water storage capacity and power generation potential.
  6. Nearby Cities: The nearest major city to Hoover Dam is Las Vegas, Nevada, approximately 30 miles (48 kilometers) to the northwest. Boulder City, Nevada, is the closest city to the dam, and it was built to house the workers during the dam’s construction.
  7. Border Crossing: Hoover Dam is a notable border crossing point between Nevada and Arizona. The state line runs along the centerline of the Colorado River, with the dam straddling this line.
  8. Scenic Views: The surrounding area offers breathtaking views of the Colorado River, Lake Mead, and the rugged desert landscape. Visitors can enjoy these vistas from the dam itself and the Mike O’Callaghan-Pat Tillman Memorial Bridge, which spans the canyon downstream from the dam.

  9. Recreation Area: Hoover Dam and Lake Mead are part of the Lake Mead National Recreation Area, managed by the National Park Service. This area offers many recreational activities, including boating, fishing, hiking, and camping.
  10. Geological Significance: The dam’s construction and the impoundment of the Colorado River have had significant geological effects on the region, including the creation of Lake Mead, changes in sediment deposition downstream, and even the gradual sinking of the surrounding landscape due to the immense weight of the dam and reservoir.

These geographical facts highlight the Hoover Dam’s unique location and environmental impact within the southwestern United States.

Historical facts about Hoover Dam

Here are some historical facts about Hoover Dam:

Unique Facts About Hoover Dam - Hoover dam facts

  1. Great Depression Project: Hoover Dam’s construction began during the Great Depression in the early 1930s. It was envisioned as a massive public works project providing employment opportunities for thousands of workers during economic hardship.
  2. Planning and Design: The idea for a dam on the Colorado River had been discussed for decades, but it was under the leadership of President Herbert Hoover that the project gained momentum. The Bureau of Reclamation, under the U.S. Department of the Interior, was responsible for planning and designing the dam.
  3. Official Start Date: Construction officially began on March 11, 1931, when President Hoover authorized the first concrete to be poured. The project was initially named the Boulder Dam.
  4. Workforce: At its peak, over 5,000 workers were employed in dam construction. These workers, known as “Hoover Dam High Scalers,” endured harsh conditions and extreme temperatures in the Mohave Desert.
  5. Labor Disputes: The construction of Hoover Dam was with its challenges. Labor disputes, including strikes, occasionally disrupted the project. The dam’s completion was also hastened by the need to create jobs during the Depression.
