At least one street on San Francisco's Treasure Island is flooded after a water main broke this morning, according to a fire dispatcher.

Construction crews were working on the island's water mains when pressure built up and one of the mains burst on Bayside Drive around 8:20 a.m., the dispatcher said.

The fire department cannot access the ruptured area to shut off the water main, according to the dispatcher.

Water officials are en route to shut off the main, the dispatcher said.

No injuries have been reported, the dispatcher said.
