UPDATE: Two Dead, About 15 Missing After Major Flash Flooding at Grand Canyon

GRAND CANYON NATIONAL PARK, ARIZONA — August 31, 2026 — A devastating flash flood that tore through the Grand Canyon over the weekend has now left at least two people dead, while authorities continue trying to account for approximately 15 people who may still be missing or unaccounted for.

The flooding began at approximately 2:30 p.m. on Saturday, August 29, in the Bright Angel Canyon and Phantom Ranch area, after heavy thunderstorms dumped intense rainfall over the canyon. The floodwaters quickly surged through Bright Angel Creek, damaging bridges, trails, buildings and critical infrastructure.

The National Park Service initially reported evacuations and widespread damage, but the situation became more serious as search teams began accounting for visitors who may have been hiking, camping or staying in the inner canyon when the flood hit.

As of Monday morning, two deaths had been confirmed and roughly 15 people were still believed to be missing or unaccounted for. Authorities cautioned that the number could change as people are located or contact family members and park officials.

More Than 60 People Evacuated

Emergency crews carried out a large-scale evacuation operation after the flood cut off several parts of the canyon.

The National Park Service said at least 62 people were evacuated from Phantom Ranch and the lower North Kaibab Trail, with additional evacuations planned from Cottonwood Campground and other affected locations.

Many evacuees were flown out by helicopter because trails and crossings had become unsafe or impassable. Those brought to the South Rim were directed to the Maswik Lodge Cafeteria, where the American Red Cross was assisting displaced visitors.

Bridges and Trails Destroyed

The force of the flooding caused extensive damage throughout Bright Angel Canyon.

Park officials said nearly all footbridges crossing Bright Angel Creek were destroyed, eliminating normal hiking access through large portions of the area.

The flood also carried metal structures and debris into the Colorado River, temporarily forcing officials to close the river to traffic while crews assessed hazards.

Phantom Ranch, Bright Angel Campground, the Phantom Ranch Canteen and cabins, and the entire North Kaibab Trail from the trailhead to Phantom Ranch remain closed until further notice.

Critical Water System Heavily Damaged

One of the most serious long-term consequences of the flooding involves the Transcanyon Waterline, which supplies water to much of the Grand Canyon’s South Rim.

Officials say the flood caused extensive damage to the system, leaving the waterline currently inoperable.

Preliminary assessments indicate approximately 40 per cent of the pipeline was damaged, creating major concerns for both visitors and the roughly 1,600 people who live and work in Grand Canyon Village.

Because of the damage, Grand Canyon National Park implemented Stage 4 water restrictions beginning August 31.

All overnight hotel accommodations inside the South Rim portion of the park are being suspended, including the El Tovar, Bright Angel Lodge, Maswik Lodge, Phantom Ranch, Yavapai Lodge and Trailer Village.

The park remains open for day visitors, but officials are asking everyone in the area to conserve water.

Search Continues for Missing Visitors

The National Park Service is asking the public to help identify approximately 15 people who may have been in the affected area.

Investigators are particularly interested in anyone who was hiking or camping along the Bright Angel Creek corridor on August 29, including people travelling along the North Kaibab Trail, staying at Bright Angel Campground or passing through the area known as “the Box” north of Phantom Ranch.

Anyone with information about someone who may have been in those areas is being asked to contact the National Park Service Investigative Services Branch at 888-653-0009.

More Storms Could Bring Additional Flooding

The danger is not necessarily over.

Meteorologists are warning that additional thunderstorms and heavy rainfall remain possible, raising the risk of further flash flooding, debris flows, rockfalls and rapidly changing trail conditions.

The risk is especially concerning in areas affected by the 2025 Dragon Bravo wildfire. Burned landscapes can shed water much faster than healthy terrain, increasing the chances of dangerous debris flows consisting of mud, ash, rocks and fallen trees.

A Major Disaster Inside One of America’s Most Famous Parks

The flooding has transformed a busy summer weekend at one of the most recognizable natural landmarks in the United States into a major search, recovery and infrastructure emergency.

Two people are now confirmed dead, approximately 15 remain unaccounted for, dozens have been evacuated and some of the Grand Canyon’s most important trails and facilities are closed.

The destruction of bridges and severe damage to the Transcanyon Waterline could also affect park operations well beyond the immediate emergency.

Search crews, park rangers and Arizona emergency officials continue working to account for visitors and assess the full extent of the damage.

Authorities are warning visitors not to enter closed areas and to closely monitor weather conditions because another round of heavy rainfall could worsen an already dangerous situation.
