Ancient Lake Manly Returns to Death Valley: Badwater Basin Lake Reforms After Record Rainfall
An ancient Ice Age lake, Lake Manly, has re-emerged in Death Valley’s Badwater Basin after record rainfall in late 2025, briefly transforming North America’s lowest point into a shallow, temporary oasis visible from satellite imagery.
Key takeaways
- Lake Manly—a prehistoric pluvial lake—has reformed as a shallow Badwater Basin lake after months of unusually heavy storms in late 2025 (NASA EarthData).
- Death Valley recorded its wettest November on record, helping refill portions of the basin and produce visible water on satellite imagery (Los Angeles Times).
- Park managers caution visitors to respect closed areas and fragile salt flats; storms also affected roads and operations in the park (National Park Service).
What is Lake Manly and where is it now?
Lake Manly was a vast pluvial lake during the late Pleistocene that once stretched roughly 100 miles and reached hundreds of feet deep, filling much of the valley now capped by salt crust. Today, the flat white Badwater Basin is usually dry at 282 feet below sea level, the lowest point in North America (Los Angeles Times).
When heavy rains accumulate, a modern, much smaller version of Lake Manly can re-form for days, weeks or months. Satellite imagery from Dec. 10, 2025, shows a dark-blue water body on the Badwater Basin salt pan—what scientists call a remnant or re-formation of Lake Manly (NASA EarthData).
Recent history: From Hurricane Hilary to 2025 storms
Modern rebirths of Lake Manly are rare but not unprecedented. In August 2023, remnants of Hurricane Hilary dropped about 2.2 inches of rain in parts of Death Valley, enough to flood the salt flat and create a temporary lake. An atmospheric river in February 2024 added roughly 1.5 inches and briefly deepened water again; park and NASA data show depths up to ~3 feet during the Feb–Mar 2024 episode, and the pool extended for miles, briefly allowing some visitors to kayak (National Park Service; Los Angeles Times).
Record rainfall in late 2025
After drying following the 2023–24 events, the basin received months of unusually heavy storms in late 2025. From September through November the park recorded 2.41 inches of rain, including 1.76 inches in November alone—Death Valley’s wettest November on record and the most rain in a single month since at least 1923. That rainfall refilled parts of the ancient lake bed; the National Park Service confirmed a shallow lake had formed in a Dec. 4 news release (Los Angeles Times; National Park Service).
What the images show
NASA’s Harmonized Landsat–Sentinel-2 imagery from Dec. 10, 2025, clearly shows pooled water in Badwater Basin framed by snow‑capped mountain slopes. The satellite view corroborates visitor reports and park observations that a visible, if temporary, lake now occupies parts of the salt pan (NASA EarthData).
Size, depth and duration: what to expect
Park officials report the current lake is smaller than the 2023–24 episode but still noticeable in places. In spots the water is knee-deep and stretches across portions of the salt pan. How long it remains depends on wind, temperature and additional precipitation; cooler weather could prolong visibility into the new year, while sun and strong winds can evaporate shallow water quickly (Los Angeles Times).
Wind, evaporation and visitor impact
Shallow lakes in open desert respond rapidly to wind. In early 2024, sustained winds pushed water miles across the basin in a “traveling lake” event; those winds also accelerated evaporation and left wide mudflats. Visitors who walked long distances or dragged watercraft left persistent footprints and drag marks that can remain until the next flood.
Park guidance: boating on Lake Manly has been ended and visitors are urged to stay on compacted surfaces near the Badwater Basin parking area to protect the fragile surface (National Park Service).
Park operations and public safety
Heavy storms and the new lake have affected park operations: some paved roads were covered by debris and temporarily closed. Key viewpoints—Zabriskie Point, Dante’s View, Badwater Basin and Mesquite Flat Sand Dunes—remained open at the time of reporting, but officials warned back‑country drivers to be cautious and prepared to self-rescue. The park posted advisories and limited certain activities to protect resources and keep visitors safe (Los Angeles Times).
Scientific and historical context
Lake Manly is a direct echo of a wetter Ice Age landscape; its modern returns illustrate how modest changes in precipitation can briefly transform extreme deserts into lakes. Scientists combine satellite imagery and park measurements to track these events and study the Basin’s response to extreme weather patterns (NASA EarthData; National Park Service).
Implications for Huntington Beach, California
Although Lake Manly is hundreds of miles inland, its reappearance can influence regional tourism and preparedness:
- Economic and tourism effects: The rare spectacle may draw visitors from Southern California, including Huntington Beach residents, potentially boosting motel, restaurant and travel services demand (Los Angeles Times).
- Infrastructure and preparedness: Storms that damaged roads inland are a reminder for local officials to review storm plans, clear drains and rehearse response actions to reduce avoidable damage.
- Water and resource planning: The event highlights the importance of targeted investments in drainage, road maintenance and emergency communications over broad, immediate policy shifts.
- Visitor conduct: Respect park rules limiting boating and avoid making lasting marks on delicate salt flats—responsible behavior preserves the landscape for future visitors.
Regional climate note
This cluster of wetter-than-usual years—from Hurricane Hilary’s remnants in 2023, an atmospheric river in 2024, to record rainfall in late 2025—demonstrates the range of weather variability. Communities like Huntington Beach should prepare for both drought and intense wet periods with practical resilience measures.
