Flash flooding causes major damage to the Grand Canyon's critical water pipeline

Flash flooding badly damaged the Transcanyon Waterline — the only pipeline that supplies water to millions of Grand Canyon visitors — with park flyovers estimating about 40% impacted and miles possibly destroyed; surveys and repairs are just beginning.
The park has halted overnight stays and imposed strict water-saving measures (short showers, turning off taps while brushing, selective flushing) as staff rely on limited stored water and past tactics like trucking in water.
A yearslong, $200M+ pipeline upgrade was underway but now faces major setbacks; repairs are difficult and costly because the route crosses extremely rugged terrain where helicopters and special materials are often needed.
