GRAND CANYON NATIONAL PARK, Ariz. (AP) — Rescue crews have discovered at least two bodies following a significant flash flood that occurred in the Grand Canyon, with forecasters warning of potential further flooding due to ongoing heavy rain. The flood, which took place on Saturday, caused substantial damage to the only water pipeline supplying the canyon, leading officials to prohibit tourists from staying at lodges and hotels within Grand Canyon National Park and to implement emergency water restrictions for local residents.
As of now, at least two individuals have been confirmed dead, and over a dozen others are reported missing after heavy rainfall affected the Bright Angel Creek area, a popular destination that attracts approximately 4.4 million visitors annually. The flood impacted areas near the Colorado River, particularly around lodges and camping sites frequented by hikers traversing the canyon.
Rescue operations involved evacuating numerous visitors by helicopter, who reported experiencing a significant deluge and were warned of potential rockslides. Witnesses described seeing large pools of logs and debris flowing down the river as they awaited rescue. Hiker Daniel Evans recounted experiencing multiple rain showers before a particularly intense 30-minute downpour on Saturday afternoon, which led to the evacuation order from park rangers.
The body of a 46-year-old man was recovered on Sunday evening near Crystal Rapids, according to the National Park Service, which did not provide additional details. Recovery efforts for a second body were ongoing as of Monday, with officials urging anyone who was in the park during the flood to contact park rangers to confirm their safety.
On Monday morning, additional rainfall was reported as the state Department of Emergency and Military Affairs coordinated with the park service and county emergency management officials in the search and recovery efforts. The summer months in the Grand Canyon are particularly risky due to the potential for flash flooding associated with the monsoon season, where clear days can rapidly transition to thunderstorms.
Forecasters have indicated that further flooding could occur as storms develop. Rain also affected areas previously burned by the Dragon Bravo fire, which was ignited by lightning in July 2025 and resulted in significant evacuations and damage to structures, including the historic Grand Canyon Lodge.
The current monsoon season has been intensified by a strong El Niño, leading to increased water vapor in the atmosphere, according to A. Park Williams, a hydroclimatologist at UCLA. This phenomenon can significantly influence weather patterns globally. Climate scientist Daniel Swain of the California Institute for Water Resources noted a strong link between human-caused climate change and the heavy rainfall observed in Arizona, citing a study that found short-term intense downpours in the West have become 10% stronger since 2000.
The flood has also severely impacted efforts to modernize the water pipeline serving visitors and the approximately 1,600 residents of Grand Canyon Village. A $208 million rehabilitation project for the pipeline and associated water delivery system began in 2023, with completion expected next year. This project is considered essential for meeting the water needs of both residents and visitors.
