Grand Canyon National Park

Grand Canyon National Park is announcing Transcanyon Waterline (TCWL) construction closure-related work for 2026.  Rockfalls occurred along a section of the River Trail in August, causing a 50-foot section of the trail to collapse and triggered the need for additional assessments and work to rebuild the trail. 

Grand Canyon National Park will reopen hotels on the park’s South Rim beginning Wednesday, Dec. 17 and will begin easing some water restrictions. Park water utility crews successfully completed complex repairs to the Transcanyon Waterline last week and resumed pumping water without identifying any new breaks. The park will continue to operate under enhanced water restrictions until the water storage tanks have adequate capacity to return to routine water conservation practices.

Grand Canyon National Park will implement additional water restrictions on the South Rim starting Saturday, December 6, due to a series of significant breaks in the 12½ mile-long Transcanyon Waterline that supplies water from the canyon for use in the park. Since mid-November, the park has faced challenges with water supply, and currently, no water is being pumped to the South Rim.

Grand Canyon National Park will close the North Rim to all visitor access on Friday, November 14, 2025, at 5:20 p.m. Sections of the North Rim are tentatively expected to reopen to visitors for the 2026 season on May 15, pending weather, trail conditions, infrastructure readiness, and completion of hazard mitigation efforts.

Grand Canyon National Park will implement Stage 3 Water Restrictions and Stage 2 Fire Restrictions beginning Oct. 31, 2025, in response to limited water availability and construction activities associated with the ongoing Transcanyon Waterline Replacement Project. Also, a temporary interruption in water pumping is scheduled for Nov. 4 through approximately Nov. 18 to allow crews to replace and test a critical pipeline segment.
