Ancient Lake Manly reappears in Death Valley — Badwater Basin briefly becomes a shallow lake after months of extreme storms
Death Valley, California (High Desert News Online) – Death Valley’s Badwater Basin, normally North America’s driest point, has been transformed as an ephemeral Lake Manly resurfaced after historic storms — Hurricane Hilary remnants and multiple atmospheric rivers — forming a shallow lake that persisted for months.
- Temporary lake grew to roughly 6 by 3 miles and ~1 foot deep, allowing limited kayaking before boating was restricted to protect the salt crust.
- Satellite imagery confirmed the water’s extent and helped managers track changes as storms and wind redistributed the shallow sheet.
- Storm sequence began with Hurricane Hilary (Aug 2023) and continued with strong winter storms and an atmospheric river in early 2024.
- Event offers scientific insight into extreme precipitation, paleoclimate evidence, and rapid evaporation in closed desert basins.
What and where is Lake Manly?
Lake Manly is the name scientists give to a large pluvial lake that filled Death Valley during the Pleistocene ice ages. At its maximum in the distant past it stretched as long as ~100 miles, fed by a wetter regional climate. Today the former lakebed is the Badwater Basin salt flat, roughly 282 feet (86 meters) below sea level, and the lowest point in North America. Modern water appearances are typically shallow and short-lived, but they form in the same basin as the ancient lake. (Outside Online; National Park Service.)
How the lake returned: from Hurricane Hilary to repeated storms
The sequence began in August 2023 when the remnants of Hurricane Hilary swept inland, delivering about 2.2 inches of rain to parts of Death Valley in a single event — more than the valley usually receives in a year. That flooding was enough to pond water across the salt flat and damage roads. Through winter and into early 2024, additional heavy storms — including an atmospheric river in early February that added roughly 1.5 inches — refilled and enlarged the water body. The combination of Hilary’s rainfall and repeated winter storms pushed seasonal totals well above normal and allowed the temporary lake to persist for months. (National Park Service; Outside Online.)
“Traveling lake” behavior and rapid change
Between Feb. 29 and March 2, sustained high winds near 40 mph pushed the shallow water roughly two miles north. Park scientists described the phenomenon as a “traveling lake”, in which the water’s migration expanded surface area while reducing depth and accelerating evaporation. Areas that had been suitable for kayaking were exposed as salty muddy flats within days. The wind-driven migration changed where visitors could safely access remaining water and altered lake behavior rapidly. (National Park Service.)

NASA confirmation from space
Satellite imagery using Harmonized Landsat–Sentinel-2 products showed the ephemeral lake as a distinct dark-blue patch centered in Badwater Basin. Space-based views confirmed the unusual size and multi-month persistence of this transient water body in one of North America’s driest places and helped managers track area and extent as storms and wind redistributed water.

Why scientists care
Climatology
Death Valley typically receives about 2 inches of rain per year. When tropical remnants and atmospheric rivers deliver comparable or larger totals in short sequences, they temporarily override long-term aridity. Tracking such episodes informs understanding of regional weather extremes and future precipitation variability. (National Park Service; Outside Online.)
Paleoclimate and geology
Although the modern lake was tiny compared with Pleistocene Lake Manly, floods in the same basin reveal how water interacts with salt crust and sediments. Short-lived inundation can expose ancient shorelines and move sediment in ways that mirror past lake behavior, offering snapshots of long-term hydrologic and sedimentary processes. (Outside Online.)
Hydrology and evaporation
Badwater Basin is a closed system with no outlet; extreme heat drives rapid evaporation. Even substantial rainfall typically results in a shallow, salty sheet that disappears in days to months. The 2023–24 episode is notable for its depth, areal extent and multi-month duration, which are rare in the modern record. (National Park Service.)
Visitor experience and park management
Visibility and access: When water was present it could be seen from the main Badwater Basin parking area. In many spots visitors could walk onto compacted salt crust near the lake edge. For a short period kayaking was allowed on parts of the temporary lake.
Protections and closures: Park staff later banned boating after winds and evaporation exposed soft mudflats. Walking or dragging equipment across soft, newly exposed mud can leave deep scars that persist until the next major flood; park managers urged visitors to stay on hardened surfaces and existing footprints. (National Park Service.)
Safety reminders for visitors
- Bring water and shade: Death Valley is remote and can be dangerously hot in summer months.
- Be cautious on wet salt and mud: Surfaces can be unstable and sticky; avoid walking beyond hardened areas.
- Heed park guidance: Follow temporary rules and closures intended to protect landscapes and public safety. (National Park Service.)
How rare is this modern return?
Thin films of water appear on Badwater every few years, but the depth, area and months-long persistence of the 2023–24 event are unusual. Satellite documentation and broad media coverage underscore how notable it is to see a sustained body of water in a place defined by record heat and drought — a clear example of extreme Death Valley weather.

Implications for The High Desert, California
Economic impact
A visible, sustained Lake Manly can temporarily boost visitor interest in Death Valley and nearby High Desert towns, bringing business to lodging, gas stations and restaurants that serve tourists. The phenomenon’s seasonal nature limits long-term benefit; operators should plan for short-lived surges in demand. (National Park Service.)
Political consequences
Local leaders are reminded of the need for emergency preparedness and resilient infrastructure as extreme storms can flood roads and damage access routes. County and state agencies should maintain updated flood-response plans and clear communication with rural communities. (National Park Service.)
Social effects
Residents may feel both awe and concern: the rare sight draws photographers, scientists and curiosity seekers while heavy storms can strain local services and create safety risks. Public education on safe recreation and the fragile nature of salt flats can reduce harmful impacts from well-meaning visitors. (National Park Service.)
Cultural relevance
The return of water to Lake Manly evokes regional history and identity: communities shaped by aridity and scarcity were briefly reminded of the basin’s ancient, wetter past. The event is a vivid illustration of how rare storms can reshape familiar landscapes. (Outside Online.)
Practical applications
Local agencies can use this event to review road maintenance, signage for sudden floods, visitor guidance, and coordination with federal partners. Businesses serving tourists should plan flexible staffing for short surges. Satellite monitoring and timely public alerts proved useful and can be integrated into future planning.
