NASA satellite shows just how big Death Valley's ghost lake really was
Hurricane Hilary and the intense winter atmospheric river storms flooded salt flats in the desert of Death Valley National Park, the driest place in North America.
Atmospheric rivers bring lake to Death Valley National Park

DEATH VALLEY, Calif. – The National Park Service recently announced that there will be no more boating at the driest place on the continent because a lake that appeared in Death Valley is disappearing, but NASA has released satellite images showing exactly how big the so-called ghost lake was.
Death Valley National Park averages just 2 inches of rain and 130 inches of evaporation a year, but it has been a boating mecca for inland kayakers since summer after a lake reappeared 10,000 years after going extinct.

Lake Manly is an extinct lake
The lake dubbed "Lake Manly" began developing during Hurricane Hilary. The monster Category 4 storm slammed Mexico in August 2023 and continued into California. The National Hurricane Center issued its first-ever Tropical Storm Warning for Southern California. In just one day, it dropped more than a year's worth of rain. The floodwater rushed into almost every basin in the national park.

"The most notable one is the one at Badwater Basin," Matthew Lamar, park ranger at Death Valley National Park, told FOX Weather in November.
Badwater Basin, a salt flat 282 feet below sea level and as far as the eye can see, is the lowest point in North America, according to Lamar. He said it filled with 2 feet of water after the storm, but since the area is normally a desert, there were no permanent instruments to measure it. Rangers and park visitors judged the depth by wading into the water.

By November, the lake was down to a couple of inches, he said. Then came the winter of 51 atmospheric rivers which drenched the West Coast. February soakers dropped another three-quarters of a year's worth of rain in a day, and kayakers set sail again.

No instruments to measure water depth in desert
NASA used the U.S.-French Surface Water and Ocean Topography satellite to measure the depth of the ephemeral lake. Over six weeks, from Feb. 2 to March 4, the water ranged from 3 feet to 1.5 feet deep. Analysts used the satellite to measure the elevation of the water's surface and combined it with U.S. Geological Survey data about the basin.
The images from NASA tell the tale of the stormy February and windy March.

"The researchers found that the water levels varied across space and time in the roughly 10-day period between SWOT observations. Right after a series of storms in early February, the temporary lake was about 6 miles (10 kilometers) long and 3 miles (5 kilometers) widest," wrote NASA in a statement. "Each pixel in the image represents an area that is about 330 feet by 330 feet (100 meters by 100 meters)."
Another storm brought strong winds to Death Valley between Feb. 29 and March 4. The winds moved the shallow lake a couple of miles. That was when kayaking was temporarily halted. Sunday, the park closed the "lake" for boating.

Don't even leave your footprints behind
"'Lake Manly,' the temporary shallow lake at Badwater Basin (formed after storms in August 2023 and February 2024) is shrinking rapidly and is now only a few inches deep. It is a minimum of 1/4 mile away from the road over rough, uneven salt and mud (no trail)," the NPS posted. "Due to the shallow depth of the lake and the damage caused by people dragging watercraft across the salt flats, the lake is closed to all boating (kayaks, paddleboards, canoes, pool floats etc.)."
Visitors can still walk in the water and enjoy the mountain reflections, though. However, park officials prohibit anyone from walking in the mud and leaving footprints, which will scar the landscape until the next wild weather event causes the lake to reappear.
