Lake Mead fell to its lowest level to-date in July 2022, when the elevation sat at 1040 feet. If the reservoir had fallen another 145 feet, it would have become a “dead pool,” unable to provide water or hydroelectric power to millions of customers.

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.
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.
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.
When the snow eventually begins to melt, gravity will take over. As the water flows down from higher elevations, it begins a long journey that does not end at Lake Mead. According to the Las Vegas Valley Water District (LVVWD) the water will slowly seep into the ground.
Investments to enhance system conservation and improved hydrology have led to significant improvements for Lake Mead this year, the federal government announced Tuesday, after the lake hit historic lows last year and the remains of several bodies were found.
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.
There are many places to swim in the bright blue waters of Lake Mead and Lake Mohave. Be aware that there are no lifeguards in the park. Always wear a life jacket. Most fatalities at Lake Mead National Recreation Area could have been avoided if the person in the water was wearing a life jacket.
Dead pool conditions would mean the end of all electric production, as well as water, from the Colorado River. Electricity would not just be the only thing lost. Without Lake Mead, Las Vegas would lose access to 90 percent of its water sources.
Despite hope that the lake will return to what it once was, Lake Mead's chance at a full recovery is slim. Jennifer Pitt, director of the National Audubon Society's Colorado River Program, previously told Newsweek that it is possible only if three years of average snowfall occur with no water use from the reservoir.
“While the amount of precipitation received in the lower basin and from tributary inflows helps, the greatest source of water for Lake Mead is still snow melt and flows from the upper basin.”
Rising temperatures due to climate change have sapped more than 10 trillion gallons of water from the Colorado River over the last two decades, enough water to completely fill Lake Mead from top to bottom, according to a recent study from researchers at UCLA.
“While the amount of precipitation received from the recent storms in the lower basin and from tributary inflows helps, the greatest source of water for Lake Mead is still from snow melt and flows from the upper basin — especially from good winter snowpack from the west slope of the Rocky Mountains,” Hendrix said.
Lake Mead's water levels currently stand at 1,050.71 feet as of May 8. According to a Maximum Probable Inflow 24 month report released in April 2023, Lake Mead's water levels could rise to 1,060.30 feet by the end of July 2023. This, in other words, is a best-case scenario for the drought-stricken reservoir.
The amount of water that melted off and made its way into the river system was enough for the Bureau of Reclamation to release far more water from Glen Canyon Dam at Lake Powell this year, which means more water flowing downstream into Lake Mead.
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.
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.
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.
