The Transcanyon Waterline, a 12.5-mile pipeline that supplies water to millions of visitors at the Grand Canyon, has suffered significant damage due to flash flooding over the weekend. Park officials estimate that approximately 40% of the pipeline has been damaged, which will complicate repairs and disrupt a long-standing project to upgrade the aging line.
The pipeline, which was completed in the 1970s, has experienced numerous breaks in recent years, with over 85 incidents since 2010. The current repair and replacement project, which began in 2023, aims to address these issues and ensure the park's water supply needs are met for at least the next 50 years. However, the latest damage will likely delay the project's progress.
The flooding has forced park officials to implement water conservation measures, including limiting shower time and turning off the tap while brushing teeth. Overnight accommodations have also been suspended, with visitors advised to check in at nearby visitor centers or ranger stations before engaging in recreational activities.
The full extent of the damage will not be known until Tuesday at the earliest, when a full survey of the pipeline is expected to be completed. In the meantime, park officials are urging visitors to be cautious and consider changing their plans if they were planning to hike, boat, or paddleboard in areas that may be prone to flooding.
The flooding has also resulted in at least two fatalities, with one person still missing as of Monday night. Roughly 80 people were rescued over the weekend, with officials working to continue rescue operations and maintain essential services within the park.
