Ancient Lake Manly Re-forms at Badwater Basin as Rare Storms Flood Death Valley
After months of unusually heavy storms, a short‑lived version of ancient Lake Manly re‑formed across Badwater Basin in Death Valley, creating a temporary shallow lake that attracted visitors and was documented by the National Park Service and satellite imagery.
Key takeaways
- An informal, short‑lived “Lake Manly” returned to Badwater Basin after months of heavy storms, as reported by the National Park Service.
- Scale and depth: the modern lake was typically a few inches to about a foot deep, and at its peak in 2023–24 grew to roughly 6 miles long and 3 miles wide (National Park Service).
- Triggering storms: remnants of Hurricane Hilary (August 2023) and an atmospheric river in February combined to deliver exceptional rainfall, documented by NASA Earthdata and Outside Online.
Main story
What is Lake Manly?
Lake Manly was a large pluvial lake that filled Death Valley during the last ice age, fed by rain and melting snow when the region was cooler and wetter. Today the ancient shoreline is the Badwater Basin salt flat, roughly 282 feet (86 meters) below sea level — the lowest point in North America (see National Park Service and Outside Online). The name “Lake Manly” is now used informally for the small, temporary lakes that form on that salt flat after rare heavy rains.
How the modern Lake Manly re-formed
The recent reappearance began with an unusual storm sequence. In August 2023 the remnants of Hurricane Hilary moved inland and dropped about 2.2 inches of rain on the basin — notable because Death Valley’s average annual rainfall is roughly 2 inches. That single event led to water pooling on the salt crust, and subsequent storms (including an atmospheric river in early February that added about 1.5 inches) helped expand and sustain the shallow lake for months, according to the National Park Service and coverage by Outside Online.
How the lake changed over time
The temporary Lake Manly was dynamic. Strong winds (~40 mph) pushed surface water north by about 2 miles in late February and early March, creating what the park described as a traveling lake
(National Park Service). Wind-driven spreading reduced average depth and accelerated evaporation, which helped the lake shrink faster. Winds also left parts of the salt flat as soft, salty mud near launch points; when winds eased water returned toward the deeper center, leaving a shallower, muddier remnant.
Scientific observation and satellite confirmation
Spaceborne observations confirmed field reports. Harmonized Landsat–Sentinel‑2 images showed Lake Manly as dark‑blue water across parts of Badwater Basin, as published by NASA Earthdata. Scientists note this episode illustrates how extreme storms can briefly reverse Death Valley’s hyper‑arid conditions and recreate Pleistocene‑era landscapes, even if only temporarily (see NASA Earthdata and Outside Online).
Park rules and visitor impacts
The sudden lake drew many visitors, but the National Park Service warned that walking and dragging boats across wet salt crust can cause long‑lasting damage. The park prohibited boating on the temporary Lake Manly to protect resources and ensure safety; visitors are asked to stay on already‑compacted routes from the Badwater Basin parking lot to avoid creating new scars on the salt flat (National Park Service).
Why this is rare and what it means for climate context
Death Valley is one of the hottest, driest places on Earth; its average annual rainfall is about 2 inches, so receiving 2+ inches from a single storm is exceptional. The sequence of Hurricane Hilary followed by winter storms and an atmospheric river produced one of the most extensive, long‑lived modern Lake Manly episodes documented by the National Park Service and NASA Earthdata. Scientists and park staff emphasize that while a single event does not prove long‑term climate trends, it demonstrates how extreme precipitation can temporarily transform landscapes usually regarded as permanently dry.
Photos and public interest
Satellite and ground photos offered rare visuals: dark water across a normally white salt flat made headlines and drove a surge of visitors. Social media amplified images from the field and from space, increasing public interest and visitation to Death Valley (NASA Earthdata; Outside Online).

Implications for Los Angeles, California
Economic impact
Tourism and services: renewed interest in Death Valley can shift travel patterns across Southern California. Los Angeles‑area tour companies, outfitters and hotels that run desert trips could see increased demand, while park closures or restrictions to protect fragile land may limit some commercial activity around Badwater Basin (National Park Service).
Political consequences
Unusual inland impacts from storms and hurricanes often spur discussions about preparedness. Los Angeles leaders and county agencies may review emergency planning for extreme rainfall, water and infrastructure resilience, and the policy implications of more frequent extreme weather events.
Social effects
Visitor pressure: the event may increase weekend visitation from the L.A. area, placing added demand on park facilities and nearby towns. It could also prompt school and outdoor groups to plan educational trips focused on geology and climate.
Cultural relevance
Images of water in Death Valley resonate with Southern California’s appreciation for dramatic outdoor spectacles. The re‑formed Lake Manly connects regional audiences to California’s geological past and can deepen interest in natural history and preservation.
Practical applications for residents and planners
Practical tips: Angelenos planning visits should check park notices before traveling to Badwater Basin. The park has prohibited boating to protect fragile surfaces and requests visitors stay on compacted paths (National Park Service). Vehicle renters and trip planners should prepare for muddy areas and temporary road impacts after storms. For planners, the episode reinforces incorporating rare but extreme precipitation into emergency response and visitor management strategies.
Summary: This rare re‑flooding of Badwater Basin is a short chapter in Death Valley’s long story — offering photos, science and lessons for visitors and regional planners (National Park Service; NASA Earthdata; Outside Online).
