The Historic Railroad Hiking Trail, just minutes from Hoover Dam, is inside Lake Mead National Recreation Area and offers a 7.5-mile roundtrip walk through 5 historic tunnels that were used for the train when building the dam. The walk is extremely flat and easy and is dirt/gravel. Gold Strike Canyon is a challenging trail, including climbing over rocks, and eventually leading to the Colorado River, below Hoover Dam; it is a strenuous hike and not advised without research and preparedness
Hoover Dam is about 2 hours from the Grand Canyon West Rim and about 4 hours from Grand Canyon South Rim.

During the Great Depression of the 1930s, thousands of potential workers arrived in the Las Vegas area, hoping to find work at the dam. Those who were hired eventually moved to Boulder City, which was a city built by the U.S. Government to house employees working on the project. Meanwhile, the U.S. government set about finding a contractor to build the proposed 60-story arch dam. The contract was awarded in March 1931 to a company called Six Companies, a group of six construction firms that had pooled its resources to work together and to meet the $5 million performance bond. In Boulder City, there are some incredible bronze statues, along the Art Walk, that depict some of the workers.

When plans were being worked on to build the dam, historical records were studied for rainfall from the previous decades. These studies of the years prior to the 1930s included some unusually wet years, which projected some higher-than-normal expectations for future years. Rainfall amounts fluctuate over the years, decades, and centuries. The last few decades have had lower precipitation in the Rocky Mountains, which is the area that provides the water for the Colorado River and Lake Mead, behind Hoover Dam. 1986 was the year of the highest water levels in recent history. The high-water mark around Lake Mead reflects that high point, and not the “normal” level of the reservoir. Although the water is lower than normal in recent years, this can change according to fluctuations in weather patterns.

Many visitors wonder about the Lake Mead water level, behind Hoover Dam. When plans were being worked on to build the dam, historical records were studied for rainfall from the previous decades. These studies of the years prior to the 1930s included some unusually wet years, which projected some higher-than-normal expectations for future years. Rainfall amounts fluctuate over the years, decades, and centuries. The last few decades have had lower precipitation in the Rocky Mountains, which is the area that provides the water for the Colorado River and Lake Mead, behind Hoover Dam. 1986 was the year of the highest water levels in recent history. The high-water mark around Lake Mead reflects that high point, and not the “normal” level of the reservoir. Although the water is lower than normal in recent years, this can change according to fluctuations in weather patterns.
Hoover Dam was built with earthquakes in mind. The dam was built to last “indefinitely” and is extremely solid with seven million tons of concrete. It is 660 feet thick at the bottom. Earthquakes are generally not considered to be a threat to the massive structure.
No. Las Vegas will not be flooded by Hoover Dam. As unlikely as it is that there would ever be a flood if it happened, the water would flow downriver to Davis Dam, which would stop a surge. Beyond that, California and Arizona are on the path. Las Vegas is at higher ground than Hoover Dam and the Colorado River and is under no threat of being flooded.
The simplest answer is no. Hoover Dam was built to be more stable and secure than it needed to be. It is shaped like a crescent wedge, with the top of the dam is just 45 feet (13 meters) thick, and its base 660 feet (221 meters) thick. The bottom is as thick as the length of two football fields end to end. It is built with solid concrete. In fact, it is built with 4.5 million cubic yards. It is built to withstand water pressure, earthquakes, erosion, and every other imaginable threat.
