The city`s lake stock has seen a drastic reduction within just three weeks, compared to the past two years, owing to the early exit of the monsoon. Currently, the lake stock stands at 93 per cent. Back in 2018, when the stock was at 91 per cent by the end of September, the city had to endure a 10 per cent water cut for the remainder of the year. This year, despite assurances from BMC officials of continuous water supply, a rainless October could escalate concerns.

The seven lakes that supply water to the city have a combined capacity of storing 14.47 lakh million litres of water. The city receives a daily supply of 3800 million litres of water. If the lakes reach their full capacity on October 1, the city enjoys an uninterrupted water supply until the following July.
