How long until Lake Mead Dead Pool?

Officials have warned that dead pool could be reached by 2025, if the lake continues drying up at the rate it is currently. But Glennon said that one would need a crystal ball to know for sure. The longer we wait, the worse it will get and there's a specific reason for this.

Outlining their latest projections for Lake Powell and Lake Mead, the nation's two largest reservoirs, federal water managers said there is a risk Lake Mead could reach “dead pool” levels in 2025. If that were to happen, water would no longer flow downstream from Hoover Dam.

Lake Powell and Lake Mead - the nation's largest reservoirs - are unlikely to refill for another 50 years and would need six consecutive years of deadly atmospheric rivers to replenish, experts say.

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.

The Bureau of Reclamation announced that the country's largest and second-largest reservoirs, Lake Powell and Lake Mead, saw improved water levels but recovery back to a full pool is a long way away, if ever.

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.

Powell's physical elevation is projected to be 3,574.30 feet on December 31, 2023. 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.

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.

Since 1983, years of drought along with high water demand have caused the lake to drop by 132 feet. Today, the lake is at only 30% capacity, its lowest level since it was built in the 1930s. Fortunately, heavy rainfall early in 2023 has relieved the situation a little, but only temporarily.

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.

The vast reservoir's water level has dropped more than 170ft (52m) since 1983, the same year the Colorado River flooded the dam's spillways. Over-extraction, extreme heat and decreased snowmelt have burdened the Colorado River Basin and nearly 40 years later, Lake Mead is down to about 27% of its capacity.

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.

The water levels for Lake Mead are projected to reach slightly over 1,065 feet by January 2024, according to the Bureau of Reclamation, in large part due to an extremely wet winter that eased the effects of the longstanding drought. In October 2022, the water levels were at a historic low, at roughly 1,046 feet.

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.

The last time Lake Mead was at maximum capacity, reaching an elevation of about 1,220 feet near the dam, was in 1983 and 1999, NASA notes.

“It has some impact, but it's not very much. I don't think you would notice Lake Mead appreciably rising just from the results of big rainstorms,” Miller said. After years of mostly seeing its water levels fall, Lake Mead has steadily risen since April.

If the reservoir dips below 895 feet (272.8 meters) – about 150 feet (45 meters) lower than where it is now – Lake Mead would reach what's called dead-pool level. Dead pool is when water in a reservoir drops so low that it can't flow downstream from the dam.

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.
