Despite heavy rain in the city for two days, the catchment area barely received any.  Except for Tulsi lake all six other lakes received 10 mm or less rain in the last 24 hours. The combined stock increased by 17,000 litres but that is due to the percolation effect. 

Tulsi is the smallest of the seven lakes supplying water to Mumbai, with a capacity of 8,046 million litres. The city’s daily water requirement is approximately 4,500 to 4,900 million litres, meaning Tulsi could be drained in just two days if it supplied the entire city.
