Weber State College's wooden basketball floor and adjoining rooms in the Dee Events Center were flooded when a water main broke, authorities said.

Assistant Ogden Fire Chief Glen Burton said the cause of the break in the 6-inch pipe just outside the west side of the building at 2 a.m. Monday was under investigation.Center Director Lou Johnson said an estimate on the amount of damage to the facility was not immediately available. However, he said the flooding could have been worse if the main, which feeds the building's sprinkler system, had not had a flow sensor that triggered a fire alarm.

"If we had not had that sensor, we could have virtually found a swimming pool this morning," he said. "It's conceivable the first four rows (of the center) could have been under water."

Johnson said the flooding also left up to four inches of mud in some areas of the center, including the Wildcat Room, press room and team rooms.

"The court had water on it, but most of it ended up under the court. We're having to pull up the edges of the court and trim around it, and hopefully, force air into that space and dry it out," he said.

Burton said the main broke just outside the center and poured in through the walls, possibly via conduit and pipe passages, into the boiler room.
