A flash flood struck Grand Canyon National Park on Saturday afternoon, resulting in at least two confirmed deaths and leaving around 15 to 20 people initially reported missing, though search efforts and permit reviews have since suggested the number of unaccounted individuals may be closer to one. The flood occurred in the Bright Angel Creek and Phantom Ranch area, a remote section popular with hikers and campers, prompting a large-scale evacuation and ongoing search and rescue operations involving state and federal agencies.
The flood began around 2:30 p.m., triggered by intense rainfall over the Kaibab Plateau that quickly overwhelmed Bright Angel Creek. The rapidly rising waters washed away footbridges, trails, and sections of the Transcanyon Waterline, the park’s sole water pipeline, which supplies drinking water and fire suppression resources across the park. Preliminary assessments indicate that about 40 percent of this 20-kilometer pipeline was damaged or destroyed. As a result, emergency water restrictions were imposed, including shutting off spigots in campgrounds on the South Rim except for restroom faucets, and bans on campfires and charcoal fires throughout much of the park.
Search and rescue teams evacuated at least 62 people by helicopter from the affected area, including hikers, park staff, and contractors working on the waterline. Among the evacuees were groups stranded by debris flows and rockslides that buried trails and altered river conditions. Rescuers recovered the body of a 46-year-old man near Crystal Rapids along the Colorado River on Sunday evening; a second body was later found though details have not been released publicly. The National Park Service (NPS) has asked the public to provide any information about hikers or backpackers who were in the affected corridor, including those staying at campgrounds or on backcountry trips.
The rushing floodwaters carried logs, boulders, and debris through the narrow canyon, creating hazardous and rapidly changing conditions. Survivors described scenes of sudden, intense flooding accompanied by loud rumbling noises, with some reporting being forced to climb to higher ground as walls of debris surged downstream. Helicopter rescues continued into Monday, although ongoing thunderstorms and forecasts for additional heavy rain have slowed recovery efforts.
Officials have closed overnight accommodations throughout the Grand Canyon, including Phantom Ranch, Bright Angel Lodge, El Tovar, Maswik Lodge, Yavapai Lodge, and Trailer Village, with only day visits and dry camping allowed for now. The Bright Angel Trail and North Kaibab Trail sections leading to Phantom Ranch remain closed pending further safety assessments. The damage has been described as significant, not only to infrastructure but also to long-term projects, such as a $208 million rehabilitation of the park's water delivery system that began in 2023 and was scheduled for completion next year.
The region’s arid landscape and steep, rocky terrain make the Grand Canyon particularly vulnerable to flash flooding events, especially during the monsoon season from July to mid-September. Burn scars from a major wildfire last summer, which impacted key watersheds draining into the Colorado River, may have further amplified runoff and debris flows during the storm. Authorities have urged visitors to exercise extreme caution in all affected areas and to remain vigilant given the elevated risk of additional flash floods, debris flows, and rockfalls.
The National Park Service, working with Arizona’s Department of Emergency and Military Affairs and other emergency management agencies, continues search and recovery operations. The agency is actively identifying those in the canyon at the time of flooding and coordinating efforts in challenging conditions exacerbated by weather and inaccessible terrain. Visitors and the public are encouraged to report any relevant information that could assist in locating missing persons or assessing the disaster’s full impact.
