A major water main ruptured underneath a street near the University of California, Los Angeles on Tuesday, unleashing a 20-foot-tall geyser that flooded part of the campus and stranded motorists on surrounding streets, according to The Associated Press.

The water gushed across the north end of the campus for several hours, submerging athletic fields and pouring into an underground parking structure, where motorists were caught in water up to their wheel wells, Los Angeles Fire Department spokesman Brian Humphrey said, the AP reported.

Humphrey said there were no injuries reported in the flooding but that fire department swift water rescue teams were on scene as a precaution and that crews helped drivers caught in the mud and flowing water, according to the AP.

Humphrey said the athletic fields and possibly some classrooms would likely suffer water damage, although it was too early to estimate, the AP reported.

Local television images showed students wading through knee-deep water as the geyser continued to pour water onto nearby Sunset Boulevard, according to the AP.

Sunset, a major thoroughfare through the city's west side, was shut down in both directions, jamming traffic during the afternoon rush-hour commute, the AP reported.

The city's Department of Water and Power said workers were working to shut down multiple valves that would stop the water from flowing from the 30-inch main without breaking any nearby pipes, according to the AP.

The DWP said the more than 90-year-old riveted steel pipe, which ruptured shortly before 3:30 p.m. local time, carries an estimated 75,000 gallons per minute, the AP reported.

Mayor Eric Garcetti, who was out of the state on vacation on Tuesday, said in a tweet that it would take a full hour to shut off water in the ruptured pipe, which dates to 1921, according to the AP. By 6 p.m. the geyser had subsided substantially but water was still pouring from a gaping hole in the asphalt.

The water main break poured thousands of gallons of water onto the UCLA campus and nearby streets, while California suffers through a record drought that has prompted state and local authorities to impose water-use restrictions on residents, the AP reported.
