A sudden flash flood in the Grand Canyon on Saturday, August 29, 2026, has left one person dead and around 15 individuals unaccounted for. The flooding, which began around 2:30 p.m. in Bright Angel Canyon, led to the airlift evacuation of over 60 people from Phantom Ranch and the lower North Kaibab Trail. Park officials are urging anyone with information about hikers or backpackers in the inner canyon along the Bright Angel Creek corridor on Saturday to contact investigators.
The flash flood caused extensive damage to the park's infrastructure. Nearly all footbridges spanning Bright Angel Creek were destroyed, making hiker access impossible. A metal building was washed into the Colorado River, and the Transcanyon Waterline, which supplies water to the park, is currently non-operational. This has led to Stage 4 water restrictions on the South Rim. Due to debris in the water, the Colorado River is closed to all river traffic until further notice.
Key areas, including Phantom Ranch, Bright Angel Campground, the Phantom Ranch Canteen and cabins, and the entire North Kaibab Trail from the trailhead to Phantom Ranch, are closed indefinitely. The Black Bridge and Silver Bridge, which cross the Colorado River, are also closed with no estimated reopening date. The incident occurred during the Southwest's peak monsoon season, and authorities warn of potential additional thunderstorms and heavy rain, which could exacerbate flooding, debris flows, and rockfalls.
The National Park Service and the American Red Cross are coordinating assistance for evacuees at the Maswik Lodge Cafeteria on the South Rim. The floodwaters caused gauges along the Colorado River to spike by as much as 9 feet in some areas. While total rainfall was modest, between 1 to 1.75 inches in the hardest-hit areas, the steep elevation drop in the rocky terrain led to rapid runoff and significant issues.
