The construction of Hoover Dam created Lake Mead in 1935, which serves as the primary storage reservoir in the lower Colorado River Basin. Water levels in Mead have declined significantly since 2000 when the reservoir peaked at more than 1,200 feet above sea level. As of October 2019, the reservoir is less than 40 percent full at just over 1,080 feet above sea level. Credit: Jirka Matousek / Flickr via Water Education Colorado

Tower with sculptures of the purpose of Hoover Dam. I love the navigation purpose. Elevator to the interior of the dam is located here.

Looking downstream of Hoover Dam. On December 13, 2019 they were not generating much power. They are using the power plants to balance grid load now since they can spin up quickly as demand dictates. They can also use power to spin up the turbines so that they can supply energy to the grid instantaneously according to Terry Fulp. He told us that the power customers in the grid are willing to pay for this flexibility.

From Wikipedia:
Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. Originally known as Boulder Dam from 1933, it was officially renamed Hoover Dam for President Herbert Hoover by a joint resolution of Congress in 1947.
