Is there water behind the Hoover Dam?

Lake Mead is the largest man-made lake (reservoir) in the United States, holding almost 29 million acre feet of water. An acre-foot of water is the amount of water that will cover an acre, one foot in depth. This water is stored behind Hoover Dam and is used throughout the Southwest.

The Dam Future While the dam is expected to last for centuries, engineers predict the structure could last for more than 10,000 years, surpassing most remnants of human civilization if humans were to disappear from the earth.

Key Points. Lake Mead has dropped by 70% due to droughts in the West and it will take many years to refill again, naturally. The reservoir is vitally important to millions of people as a source of water, electricity, and recreation.

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.

Daily releases are made to meet downstream municipal and agricultural water demands while hourly releases are made to coincide with peak hydropower demand. River levels on the lower Colorado River vary based on Hoover, Davis, and Parker dam releases.

Lake Mead expected to have gained 20 feet of water by end of 2023. By the end of the year, the water level at Lake Mead is expected to be at least 20 feet higher than it was in January, according to a Bureau of Reclamation forecast released this week.

Electricity would not just be the only thing lost. Without Lake Mead, Las Vegas would lose access to 90 percent of its water sources. If Lake Mead were to reach dead pool, it would technically still be able to supply drinking water to Las Vegas. But there will not be enough water for agricultural activities.

The Lake Mead problem could be resolved by draining Lake Powell and storing the water in Lake Mead. More than 5% of the water in the Colorado River evaporates off the surface of Lake Powell - which never should have been built.

Officials have warned that dead pool could be reached by 2025, if the lake continues drying up at the rate it is currently.

While there is no door in the middle of the dam, there are several access points and tunnels that allow workers and maintenance crews to access different parts of the structure. It is an important part of the dam's infrastructure, ensuring that it can continue to function properly and safely for many years to come.

Mead reaches dead pool at 895 feet. If Lake Powell reaches dead pool, the US Bureau of Reclamation—which declined our interview requests—would be unable to meet its obligation to deliver water downstream to Lake Mead. In which case, 40 million people would be affected.
