Story summary

The U.S. Park Service reported that an Aug. 29 flood killed two hikers, left one missing, and forced evacuations.
The flood damaged or destroyed about 40% of the 12.5-mile Transcanyon Waterline, threatening South Rim water supply.
Nearly all footbridges over Bright Angel Creek were destroyed, cutting off key hiking routes.
Scientists said the flood resulted from the 2025 Dragon Bravo Fire burn scar, severe drought, and record El Niño rains.

History

Historical Context

In 1988, a drought-driven blaze burned about 36 % of Yellowstone National Park, involving roughly 9,600 firefighters and costing $120 million. The disaster spurred the National Park Service to adopt a stricter fire-management plan in 1992 that emphasizes natural fire use and protective design. Those policies now guide the response to the 2025 Grand Canyon flood that follows a recent large fire.
