Is Hoover Dam in trouble?

But the climate change-fueled drought and overuse of the Colorado River's water is pushing Lake Mead lower and threatening the dam's hydroelectricity production. Declining water flow has cut the dam's power generation capacity almost in half – around 1,076 megawatts – as of June.

D.J. Jenner, the owner of Las Vegas Scuba, who has been observing the lake for years, told Impact that the water levels have gone down roughly 40 feet since he started his business. There's still plenty of water out here for people to come out and enjoy the lake, but it is going down pretty quickly, he said.

Following the attack on Pearl Harbor in 1941, security was again reinforced at Hoover. As a major supplier of electricity to the U.S. defense industry, the dam was deemed to be a prime military target.

The construction and design of the Hoover Dam is so strong that it is expected to last 10,000 years. The bowlike shape of the massive dam channels the wind, hitting the dam straight up and causing the water to spill “up” instead of “down.”

With intervening flows between Lake Powell and Lake Mead of 1.32 maf in CY 2023, Lake Mead's physical elevation is projected to be 1,065.42 feet on December 31, 2023. The WY 2023 unregulated inflow into Lake Powell in the August Probable Maximum inflow scenario is 13.75 maf, or 143% of average.

Studies show that a project like this would be possible, though it would take decades of construction and billions of dollars. Maybe even trillions.

Some speculate the water would spread into the Mojave National Preserve and communities in southeastern California all the way to the Salton Sea, an area that was routinely flooded by the Colorado River before the dam was built in the 1930s.
