The Vihar lake, one of the seven lakes supplying water to Mumbai, began overflowing on Monday after constant heavy rains in the city, the civic officials said.

"The Vihar lake began to overflow at 2:45 pm on Monday," the Brihanmumbai Municipal Corporation (BMC) Water Engineering Department said.

This makes six out of seven lakes that have now reached full capacity and started overflowing during this year’s monsoon, the officials said, adding that the steady and heavy rainfall in the catchment areas over the past few days has significantly increased the water levels in the reservoirs.
