In the worst-case-scenario, the water level could fall to just above 990 feet in July 2024. Karyn Stockdale, National Audubon Society's senior director for western water, told Newsweek: [Lake Mead] could be at dead pool within a couple of years.

Lake Mead is shrinking — and it's not stoppingExperts say the NASA images show how much the reservoir has changed. The new images show Lake Mead creating a “bathtub ring,” a phenomenon where there's a light-colored outline where water used to be. When the lake was at capacity, water would fill those areas.
About 60% of the area still is in drought. It would actually take six more years of heavy rainfall in a row to refill the Lake Mead reservoir completely. Time is ticking to solve the problem before future droughts dry up the lake completely.
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.
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.
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.
Lake Mead's water level continues to fall to historic lows, bringing the reservoir less than 150 feet away from “dead pool” — so low that water cannot flow downstream from the dam. The loss of water entirely from this source would be catastrophic.
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.
After falling to record lows in 2022, Lake Mead has seen its water levels rise 3 feet above projections after a precipitation-heavy winter. But experts warn it's only a temporary reprieve without a comprehensive water management plan.
If the water levels dip much lower, the Colorado's northernmost reservoir won't have enough in the tank to both fill Lake Mead downstream and generate any hydropower, which would have devastating effects on the electricity grid in the western US.
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.
“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.”
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.
The water elevation in Lake Mead is around 1,040 feet above sea level. At 950 feet, Hoover Dam will be at its lowest point to be able produce power, according to the US Bureau of Reclamation.
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.
