The Lake Mead – A Triumph of Engineering and Nature

Lake Mead, the lake created by the Hoover Dam, is a breathtaking feat of engineering and a testament to human ingenuity. Named after Elwood Mead, the commissioner of the Bureau of Reclamation, the reservoir is not only a vital source of water and power for millions of people, but also a stunning recreational area drawing in millions of visitors each year.

The Birth of Lake Mead

It all began with the construction of the Hoover Dam in the 1930s, a monumental undertaking during the Great Depression that employed thousands of workers. The dam was built to control the mighty Colorado River, which often flooded the surrounding areas, wreaking havoc. As the dam was completed, the rising waters of the Colorado River formed what we now know as Lake Mead.

Key Statistics and Features

Lake Mead is no ordinary lake; it’s the largest reservoir in the United States by volume when at full capacity and stretches for approximately 112 miles. Its maximum depth reaches around 500 feet, and its 550-mile-long shoreline is dotted with spectacular rock formations and pristine beaches, making it a haven for outdoor enthusiasts, boaters, and anglers.

Impact on the Environment and Wildlife

While Lake Mead is a crucial water source for numerous communities, its formation also resulted in the submersion and alteration of natural ecosystems and habitats. The changing water levels over the years have posed challenges for the region’s flora and fauna. Despite this, the lake remains a critical refuge for a variety of wildlife, including desert bighorn sheep, coyotes, and migratory birds.

Challenges and Changes

In recent years, Lake Mead has faced significant water level declines due to prolonged drought and increased demand for water. These conditions have sparked concerns about the sustainability of the reservoir and have led to ongoing efforts to manage and conserve its precious water resources, highlighting the delicate balance between human needs and ecological preservation.

Misconceptions About the Name of the Lake Created by Hoover Dam

Lake Havasu

Lake Havasu is a popular misconception when it comes to the lake created by Hoover Dam, but it is, in fact, incorrect. Lake Havasu is located along the Colorado River, but it is not the reservoir formed by Hoover Dam. The lake created by the dam is known as Lake Mead, named after Elwood Mead, who was a key figure in the planning and development of the dam. Lake Havasu, on the other hand, is formed by the Parker Dam, which is downstream from Hoover Dam.

Lake Tahoe

Lake Tahoe, though a well-known and picturesque lake in the Sierra Nevada mountains, is not the body of water created by Hoover Dam. Lake Tahoe is located far to the west of the dam, spanning the border between California and Nevada. The reservoir formed by Hoover Dam is indeed Lake Mead, which holds the distinction of being the largest reservoir in the United States in terms of water capacity when at full capacity.

Lake Powell

Lake Powell, situated in northern Arizona and southern Utah, is often mistaken as the lake created by Hoover Dam. This misconception stems from the fact that Lake Powell is also formed by the Colorado River. However, Lake Powell is actually a reservoir created by the Glen Canyon Dam, which is located over 500 miles upstream from Hoover Dam. Lake Powell and Lake Mead, while both created by dams along the Colorado River, are distinct bodies of water with separate dam systems governing their water levels and usage.


In conclusion, the lake created by Hoover Dam is known as Lake Mead. This impressive man-made reservoir not only provides water and hydroelectric power to the surrounding areas, but it also offers recreational opportunities for locals and tourists alike. With its striking views and ample opportunities for boating, fishing, and hiking, Lake Mead is a popular destination for outdoor enthusiasts.
