Overnight hotel lodging is closed at Grand Canyon National Park following a series of breaks in the only water pipeline that serves the park.
The restrictions will run throughout the Labor Day weekend when most hotels are at or near capacity.
The Transcanyon Waterline serves about 2,000 residents at Grand Canyon Village and millions of visitors each year. Park spokesperson Joelle Baird says campers are also affected.
"We are also working to conserve water by instituting dry camping. So we are shutting off water and spigot access at all campgrounds here on the South Rim," she said.
Baird says the almost 1,000 visitors who had plans to stay overnight will have to find other options. Officials hope to have water restored by next week.
The 12.5 mile-long Transcanyon Waterline, originally built in the 1960s, supplies potable water for facilities on the South Rim and inner canyon. Park officials say it has exceeded its expected lifespan.
Since 2010, there have been more than 85 major breaks that disrupted water delivery, but none that have forced what park officials call “Stage 4” water restrictions. That is, until four recent significant breaks.
