Powerful flash flooding swept through the Grand Canyon over the weekend, crippling a key water line and prompting the National Park Service to impose emergency water restrictions as crews continued searching for missing hikers.
The NPS said stage four water restrictions will take effect at 12:00 p.m. Monday after Saturday’s flooding caused “extensive damage to infrastructure,” including the Transcanyon Waterline, the main system that supplies water to the park. Officials said one person was killed and as many as 15 others may be missing, though they emphasized that the number remains an estimate.
Park officials said the body of a 46-year-old man was recovered from the Colorado River on Sunday night. His name has not been released publicly.

The National Park Service has asked the public to share any information that could help locate the 15 people believed to be missing.
“The National Park Service is asking anyone who knows of hikers or backpackers who were in the inner canyon along the Bright Angel Creek corridor on August 29, as well as anyone who had a campground reservation in the affected corridor, to provide information to the National Park Service Investigative Services Branch,” NPS said in a statement.

Park officials say they have so far evacuated at least 62 people since the Saturday flooding.
The stage 4 water restrictions affecting the rest of the park include forced dry camping with no access to water spigots, the temporary closure of overnight lodgings, and a strict no-fire rule for the South Rim and inner canyon areas.
The flooding struck Bright Angel Canyon and the Phantom Ranch area on Aug. 29, according to NPS, which added that nearly all footbridges spanning Bright Angel Creek were destroyed.
Arizona Gov. Katie Hobbs said state emergency officials are coordinating with federal and local authorities as the search continues.
“My heart is with the families and loved ones of every person unaccounted for after the flash flooding at the Grand Canyon,” Hobbs wrote on X. “DEMA is coordinating with NPS and Coconino County Emergency Management to support search and recovery efforts.”

Arizona Secretary of State Adrian Fontes called the flash flooding “devastating” and thanked first responders for searching for those still unaccounted for and evacuating others from the affected area.
“The physical damage includes a historic lodge near the bottom of the site and untold environmental upheaval,” Fontes said in a statement. “I send my prayers to the community as the search for those unaccounted for continues.”
