Officials say a pipeline valve broke sending water down the hillside.
"It was quite powerful," says Jay Lowder, director of Ogden City's Public Works department. "It took down several sections of jersey barriers which is extremely heavy.
Officials estimate about 200,000 gallons of water came down in a span of about 45 minutes. City officals say an air pressure valve blew off from one of the water lines that feeds water into Ogden's resevoir. But they used an auxiliary line to keep water flowing into the resevoir.
"They (residents) should have the same pressure," Lowder says. "We're feeding everyone even canyon residents should have water."
Crews removed the debris from the highway. It's a route that leads into Eden and Huntsville. But officials say it will remain closed for the next 24-hours.
"This road should be open in 24 hours," says Lowder. "We have to make sure hillside is stable and that everything is good and safe before we let the public in. We don't want anyone hurt."
He says they're just thankful the highway was empty when the water came rushing down.
"That is very true," says Lowder. "We're very lucky on this whole incident."
Late Wednesday, UDOT reassessed the danger and are now considering opening the canyon later in the evening. Meanwhile, motorists are being detoured through Weber Canyon or the Ogden Divide in North Ogden.
