Arizona, California and Nevada are proposing to voluntarily save at least 3 million acre-feet of water in Lake Mead through 2026, over and above any other water cuts to which we've previously agreed. That's enough over three years to cover the entire city of Phoenix in more than 9 feet of water.
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.
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.
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.
“Although every drop counts, the reality is that the rain we received from Tropical Storm Hilary and runoff into the tributaries that enter Lake Mead as well as reduced releases from Hoover Dam — due to a decrease in downstream demand — has had some minor impact on the lake's elevation,” according to U.S. Bureau of ...
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.
The tropical storm brought nearly a monsoon season's worth of precipitation in just a few days. But that heavy rainfall likely had little effect on Lake Mead's water levels.
But while Lake Mead has filled up slightly since its low point of July 2022, the Bureau of Reclamation anticipates that the water levels will start to decline again come spring. A Bureau of Reclamation study published in January predicted that Lake Mead could reach a new all-time low in 2023.
As mentioned, it's possible for the water level in Lake Mead to drop to the point where the dam cannot generate hydroelectric power. However, it's very unlikely that the lake would completely run out of water.
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.

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.
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.
