NASA satellite images show Lake Mead water levels plummeting to lowest point since 1937

Satellite pix launched with the aid of NASA this week exhibit a dramatic drop in water degrees over the ultimate 22 years at Lake Mead.
NASA validated that water degrees in Lake Mead, positioned in Nevada and Arizona, are at their lowest on the grounds that April 1937, when the reservoir was once being crammed for the first time.
As of Monday, Lake Mead, the biggest reservoir in the United States, was once stuffed to 27% capacity, in accordance to NASA.
The snap shots shared through the NASA Earth Observatory, taken in 2000, 2021 and 2022, exhibit Lake Mead performing to develop much less and much less full of water, even in the one-year span between 2021 and 2022. The photograph from 2000 suggests swaths of Lake Mead full of water, whilst the photograph from 2022 solely suggests one section, regarded as Overton Arm, filled.

The lake's water tiers have fallen almost one hundred sixty ft due to the fact July 2000 and 26 ft because July 2021.
The severity of this loss is underlined by using its affect on these who have relied on Lake Mead's water for decades. The pics additionally arrive as states all through the West ride excessive ranges of drought – with 74% of 9 Western states presently reporting some degree of drought, and 35% going through excessive levels, in accordance to the U.S. Drought monitor.
"The biggest reservoir in the United States substances water to tens of millions of humans throughout seven states, tribal lands, and northern Mexico," NASA Earth Observatory's information launch reads. "It now additionally affords a stark illustration of local weather exchange and a long-term drought that may additionally be the worst in the U.S. West in 12 centuries."

In current months, the unexpectedly receding waters at Lake Mead have published human bodies, ghost towns, a crashed B-29 Superfortress and more.
"This is simply the tip of the iceberg," Travis Heggie, a former National Park Service professional who has studied deaths at Lake Mead Recreation Area, informed USA TODAY in May.
The water elevation at Hoover Dam, which fashioned Lake Mead, is losing significantly. According to records from the U.S. Bureau of Reclamation, the water elevation of Hoover Dam used to be nearly 1,200 ft in July 2000. As of July 18 this year, it had fallen to about 1,040 feet.
The remaining time Lake Mead used to be at most capacity, attaining an elevation of about 1,220 ft close to the dam, used to be in 1983 and 1999, NASA notes.
Lake Powell, which sits above Lake Mead in northern Arizona and southern Utah, is additionally at dangerously low levels. Similar to Lake Mead, Lake Powell is now at 27% capacity, in accordance to NASA.
Earlier this summer, the U.S. Reclamation Commissioner warned surrounding states that the losses on the Colorado River device supposed water customers would want to make greater immediately cuts to defend future resources and electricity technology at each Hoover Dam and Glen Canyon Dam, which backs up Lake Powell upstream.
The Bureau of Reclamation will launch a set of projections for 2023 in August, which that ought to set off even deeper cuts in water usage.
