The National Park Service said flash floods swept through a section of Arizona's Grand Canyon, leaving one person dead and 15 others unaccounted for.

The flooding struck the Bright Angel Canyon and Phantom Ranch area at about 2:30 p.m. local time Saturday. Recovery crews found the body of a 46-year-old man near Crystal Rapids along the Colorado River on Sunday evening.

"As of this evening, recovery operations have been completed for a 46-year-old male near Crystal Rapids along the Colorado River. The Coconino County Medical Examiner's Office is currently onsite. There is no additional information to share at this time. We will provide updates as soon as available," the National Park Service wrote on X late Sunday.

The flooding also damaged the Transcanyon Waterline, forcing the National Park Service to implement strict water restrictions across the area. The outage could affect drinking water supplies for visitors, as well as operations at hotels, restaurants, campgrounds, and even emergency facilities.
