“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.”

“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 sees 'significant improvement' in water levels after drought led to disturbing discoveries. In October 2022, the water levels at the reservoir were roughly 1,046 feet.
After falling more than 27 feet since the start of the year, Lake Mead got a bit of a bump thanks in part to the August monsoon season. But in the face of a megadrought that has gripped the Southwest for more than two decades, the small uptick is a drop in the nation's largest bucket of water.
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.
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.
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.
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.
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.
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.
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.
Most of our rainwater travels untreated through gutters, storm drains, channels, washes and eventually into the major source of our drinking water - Lake Mead. All storm drains lead to lake mead. Stormwater that falls in the Las Vegas Valley picks up pollutants and travels untreated to Lake Mead.
A team of scientists at UCLA estimated that from 2000 to 2021, rising temperatures led to the loss of about 32.5 million acre-feet of water in the Colorado River Basin, more than the entire storage capacity of Lake Mead, the country's largest reservoir.
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.
Typically, Lake Mead's water levels rise over the winter and early spring months and start to decline in March. However, with the amount of snowfall supplementing the lake through the spring as it melted, this year the lake began rising in earnest in May and continued its upward trek through mid-September.
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.
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.
