Is Lake Mead going to disappear?

Lake Mead is shrinking — and it's not stopping Experts 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.

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.

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 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.

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.

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.

In a worst case scenario, Lake Mead could reach as low as 992 feet by the end of July 2024, according to a two-year probabilistic projection of the Colorado River system by the Bureau of Reclamation, released in August 2022.

If the Hoover Dam shuts down, it will have a ripple effect in the states of Nevada, Arizona, and California. There will be less water to go around, power will have to come from less clean sources, and all industries will be impacted some way or another.

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.

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.

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.

Water taken directly from Lake Mead, the Colorado River or the underground water table isn't safe for people to drink, but those are the sources of Southern Nevada's drinking water. Before it hits a glass, Las Vegas Valley's water must run through two Southern Nevada Water Authority facilities.

Las Vegas has two systems for disposing of excess water. The sewage system carries sink and toilet water to a treatment plant, where it's processed before being sent to Lake Mead. Rain and runoff water travels through storm drains and channels directly to the Las Vegas Wash and on to the lake.
