Lake Mead would reach dead pool if the water level dropped to 895 feet, said Patti Aaron, public affairs officer for the U.S. Bureau of Reclamation's Lower Colorado Basin Region.

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.
Although a physical collapse is not likely, officials believe that Lake Mead's water levels could reach what is known as the dead pool in just a few years. If this were to happen, it would mean no hydropower, no water supply, and all operations dependent on the dam would cease.

What happens if Lake Mead dries up forever? If Lake Mead were to run out of water, the Hoover Dam would no longer be able to generate power or provide water to surrounding cities and farms. The Colorado River would essentially stop flowing, and the Southwest would be in a major water crisis.
Lake Powell and Lake Mead are unlikely to refill for another 50 years - and would need SIX consecutive years of deadly atmospheric rivers to replenish.
Downriver towns and major cities would see the most damage, in the event of the dam's physical collapse. Water flows would engulf many towns and growing cities around Mohave county, including Laughlin, Nevada; Needles, California; Lake Havasu, Arizona; and even as far south as Yuma, Arizona, and San Luis Rey, Colorado.
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.
As a decades-long drought parches the American West, Lake Mead's water supply has suffered, causing the man made reservoir's shorelines to dramatically recede and reveal some remains that were once submerged.
Although Lake Mead gradually began filling again after Lake Powell reached the minimum pool required for power generation in that reservoir in 1965, full pool in Lake Mead was not reached again until 1983.
Rainfall doesn't immediately add inches to the nation's largest reservoir. Lake Mead is enormous, and even the storm that dumped 8-10 inches of rain at Mt. Charleston covered a much smaller area than the lake. “We saw Mead's water level tick up a couple tenths of an inch.
But that heavy rainfall likely had little effect on Lake Mead's water levels. The reservoir sat at about 1,063.4 feet in elevation when the rains started on Friday. By Monday night, it had ticked up to 1,063.8.
As much as we clearly wanted it to, Hurricane Hilary couldn't help with that. Its rain didn't reach into the Rockies to sate those soils. And while Hilary drenched areas near Lake Mead, it gained less than a foot of elevation in the days after the storm (it is a big lake, after all, which takes a lot of water to fill).
As crazy as it sounds, engineers say the idea is technically feasible. It would involve building a system of dams and pipelines to move the water uphill across multiple states over the Continental Divide. Gravity would then work in our favor to drop the water down to the Colorado River watershed.
Record snowfall in the West wasn't enough to alleviate drought impacting Lake Mead. The record snowfall in the West wasn't enough to permanently alter the course of the drought impacting Lake Mead. FOX Weather's Robert Ray reports on the ongoing water issues and the Colorado River.
Still, the drought deficit is so large, experts say the West would need four or five more years of snowmelt like this year's to really fill up Powell and Mead.
