Much of the campus of the University of California, Los Angeles was under water on Tuesday after a water main ruptured nearby, flooding everything from parking garages to the iconic Pauley Pavilion basketball stadium with an estimated 10 million gallons of water.

The water was shut off at 7pm PT Tuesday and the area has started to dry out as of Wednesday.

But the damage – particularly to Pauley Pavilion, which underwent a $136 million upgrade just two years ago – had already been done and could be extensive. And that’s to say nothing of the hundreds of cars that were left submerged overnight in two underground parking garages.

“Pauley Pavilion has taken quite a bit of water,” UCLA Chancellor Gene Block told reporters Tuesday night, according to NBC News. “It’s painful. It’s a beautiful structure. We’re of course concerned. We’ve got to let it dry out and see where we are.”

Classes resumed Wednesday.
