Water Management in Las Vegas

Las Vegas thrives in the desert due to the Hoover Dam, built in the 1930s, which provides hydroelectric power, flood control, and water for irrigation. The dam created Lake Mead, a crucial water source for the city. In the 1950s, pipelines began transporting water from Lake Mead to Las Vegas, enabling population growth. Today, Las Vegas recycles much of its water, returning it to Lake Mead, ensuring a sustainable water supply.
