National Park Service officials confirmed a second fatality on Monday following a devastating flash flood that swept through a section of the Grand Canyon over the weekend.
Helicopter evacuations were required to rescue dozens of visitors as the deluge destroyed trails and critical infrastructure. Fifteen individuals remain missing or unaccounted for, with the NPS warning that additional heavy rain and thunderstorms could trigger further debris flows, flash floods, or rockfalls.
“With deep monsoonal moisture in place and already saturated soils in some locations, an elevated risk of flash flooding will be in place through Monday,” the National Weather Service (NWS) stated.
Park authorities are urging the public to share any information regarding hikers or backpackers who may have been exploring the inner canyon near Bright Angel Creek, as well as campers holding reservations in the vicinity.
Flash floods are a recurring hazard in the region, particularly during the monsoon season from June to September. Intense rainfall often hits the arid landscape, rapidly filling narrow rock formations. Visiting the Grand Canyon—a crown jewel of the US national park system—carries specific risks during the summer due to these monsoonal flash floods, where clear skies can swiftly transition into severe thunderstorms and torrential downpours.
The torrential rain fell upon hardened, sparsely vegetated steep terrain while the Grand Canyon region and the Colorado River basin remain entrenched in a severe drought contributing to a widespread water crisis.
Scientists have frequently cautioned that the climate crisis drives more intense extremes and volatile shifts between wet and dry conditions. The sudden, severe rainstorm that triggered this catastrophic flood may have been amplified by the historic El Niño, which has significantly raised Pacific Ocean sea surface temperatures and can influence global weather patterns.
The NWS has issued flood watches across a large portion of the south-west, including northern Arizona. Officials are advising against visiting creeks, slot canyons, burn scars, and low water crossings where flash floods can develop rapidly.
Footage recorded by hikers prior to their helicopter rescue captured churning brown waters carrying large metal objects and other debris. Several individuals crossed bridges just moments before they were swept away by the rising waterway.
“It must have been, like, 10 minutes afterwards—we crossed the bridges to get to the evacuation zone,” hiker Gabriel Burgeman recounted to a local news station. “We were just barely in time to cross them before they got wiped out.”
The body of a 46-year-old man was recovered Sunday evening near Crystal Rapids along the Colorado River, the NPS reported, without releasing further details. At least one other body has been recovered, according to a statement posted on Facebook by Grand Canyon national park, though details remain undisclosed.
Initial assessments indicate that approximately 40% of a key pipeline supplying drinking water to tourists and residents has been damaged or destroyed. The 12.5-mile (20km) Transcanyon Waterline has experienced dozens of breaks in recent years. A repair and replacement project exceeding $200 million was already underway when the floods struck.
This pipeline transports water from one side of the canyon, down to its base, across a bridge, and back up the opposite side of the rugged terrain. Repairing breaks caused by rockfalls or flash floods is notoriously time-consuming, hazardous, and expensive, complicating efforts to address the current damage.
Emergency water restrictions commenced on Monday, shuttering all overnight lodges and hotels within Grand Canyon national park and turning off campground spigots on the South Rim. Year-round residents were instructed to conserve water. The park had implemented water conservation measures even prior to the latest flooding and infrastructure damage.
The Saturday flooding in Bright Angel Creek, which feeds into the Colorado River, necessitated the airlifting of more than 60 people from the canyon’s depths.
Parth Desai was hiking through a narrow passage in Bright Angel Canyon alongside fellow physicians and a park ranger when the heavy rain began on Saturday.
“We saw the creek flood, waterfalls coming up out of nowhere, boulders, mud, landslides happening everywhere,” he reported.
Torrential waters obliterated footbridges over the creek and dramatically altered the landscape, widening the creek bed and either extending an existing river rapid or carving a new one. The flood dealt a severe blow to ongoing efforts to modernize the pipeline that serves 6 million annual visitors and approximately 1,600 residents of Grand Canyon Village.
“Heaven help us if the whole thing down there at the bottom has to be reconstructed,” remarked Jack Schmidt, director of the Center for Colorado River Studies at Utah State University. “Where are they going to get the money?”
Suspending overnight stays due to water shortages is uncommon, though the pipeline has a history of failures over the years. Despite large potable water storage tanks on the South Rim, they will not be replenished while the pipeline remains out of service.
A $208 million rehabilitation of the pipeline and associated water delivery system upgrades commenced in 2023, described by the park service as a vital investment to meet the needs of residents and visitors. The project was slated for completion next year.
In unrelated weather events, officials in San Antonio, Texas, reported two storm-related deaths on Sunday following a severe storm two days prior.
Police stated that a 46-year-old woman died after being caught in rushing water in San Pedro Creek north of downtown, according to Texas Public Radio. A companion escaped safely, police confirmed.
Separately, police reported that a man in his 50s was found at Woodlawn Park on Sunday morning.
The woman’s death is being investigated as a drowning, while the man’s death is considered a possible drowning, according to police.
