A deadly flash flood at Grand Canyon National Park has prompted Stage 4 water restrictions and the closure of all overnight accommodation on the South Rim, as officials respond to extensive damage caused by the severe weather.
The “significant flash flooding” struck the Bright Angel Canyon and Phantom Ranch areas on Saturday, 29 August, according to the National Park Service (NPS). Two people were confirmed dead, while more than 80 people were evacuated from the affected areas. At least one person remained unaccounted for in the days following the disaster, according to CBS News.

The flooding caused widespread damage to infrastructure in the inner canyon, including nearly every footbridge spanning Bright Angel Creek. More than 60 people were evacuated by helicopter from Phantom Ranch and the lower North Kaibab Trail as floodwaters swept through the area.
One of the most significant consequences has been damage to the Transcanyon Waterline, the system that supplies water from the canyon for use throughout the park. The waterline is currently not operational, leaving the Grand Canyon with limited water reserves and forcing officials to introduce Stage 4 water restrictions on the South Rim.

Under the restrictions, all overnight guest accommodation operated by park concessionaires has been closed for the foreseeable future. This includes El Tovar, Bright Angel Lodge, Maswik Lodge, Phantom Ranch, Yavapai Lodge and Trailer Village RV Park. Hotels located outside the park in Tusayan are not affected by the restrictions.
“These measures are crucial for ensuring the safety and sustainability of water resources,” the NPS wrote in a statement. “We are asking residents and visitors to help conserve water by limiting showers to five minutes or less, turning off faucets while shaving or brushing teeth, flushing toilets selectively, washing laundry with full loads, and reporting leaks to the appropriate offices.”

Camping is also limited. Only dry camping is permitted on the South Rim, with campground water spigots turned off, although bathroom faucets remain operational. Fires are prohibited in the South Rim and inner canyon areas, including wood-burning and charcoal fires.
The park itself remains open for day use, with food and beverage services, the Grand Canyon Clinic and the Post Office continuing to operate, although some services may have reduced hours.
The Colorado River has also been closed to river traffic until further notice because of metal structures and debris entering the river. Visitors with upcoming river trips have been advised to contact their commercial outfitter or the NPS River Permits office for information specific to their trip.

The flooding occurred during the region’s monsoon season, when intense rainfall can rapidly funnel through the Grand Canyon’s steep, rocky terrain. The Guardian reported that the storm also affected areas scarred by the 2025 Dragon Bravo wildfire, where reduced vegetation can increase runoff. Researchers cited by the newspaper also pointed to drought, warming temperatures and a potentially stronger El Niño as factors that may have contributed to the extreme rainfall.
With further thunderstorms and heavy rainfall possible, the NPS has warned that additional flash flooding, debris flows, rockfall and rapidly changing trail and river conditions could occur.
