Watch: Flash flood sweeps through Grand Canyon

Heavy rainfall triggered flash floods in the Grand Canyon over the weekend, resulting in at least two deaths and 15 people missing, according to CBS News. The floods also damaged the Transcanyon Waterline, a 12.5-mile pipeline that supplies water to millions of Grand Canyon visitors, with around 40% of it damaged or destroyed, as reported by the Associated Press.

The floods prompted the evacuation of over 60 people, with survivors describing a desperate effort to reach higher ground as they ran through rising muddy water. According to ABC News, two survivors, Gabriel Bergemann and David Gregory, who were backpacking at the bottom of the national park, said they were told by park rangers to run across a footbridge over a raging creek to higher ground, just before a wall of water came through and washed the bridge away.

The damage to the pipeline has set up a tricky repair scenario, with officials warning of significant water reductions to protect the limited stored water on the South Rim. The park's infrastructure, visitors, and year-round residents may face long-term implications from the damage, although these are not yet clear. A search continues for those still missing, with one individual identified as Dr. John Guisti, a New York chiropractor.
