Northern Arizona University researchers are studying how last year’s Dragon Bravo Fire impacted the water supply at the Grand Canyon. The blaze, which was ignited by lightning on July 4, 2025, burned more than 145,500 acres on the North Rim, making it the seventh-largest wildfire in the state’s history. The Transcanyon Waterline pulls water from Roaring Springs and delivers it throughout Grand Canyon National Park. Snowmelt on the Kaibab Plateau feeds the aquifer that supplies Roaring Springs. … The burn scar on the Kaibab Plateau changed the hydrology of the landscape and, as a result, changed the quality of the water that seeps through the ground.
