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

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

But the damage – particularly to Pauley Pavilion, whichunderwent a $136 million upgrade just two years ago – had alreadybeen done and could be extensive. And that's to say nothing of thehundreds of cars that were left submerged overnight in twounderground parking garages.

“Pauley Pavilion has taken quite a bit of water,” UCLAChancellor Gene Block told reporters Tuesday night, according to NBC News. “It's painful. It's a beautifulstructure. We're of course concerned. We've got to let it dry outand see where we are.”

Classes resumed Wednesday.
