In July alone, Mumbai has seen rainfall of 1,152.6mm while the monthly average rainfall is 840.7mm. Rains are expected to subside starting Friday with the IMD issuing a ‘green alert’.
However, the catchment lakes in Thane and Nashik districts haven’t received much rain. This is important because the metropolitan region relies heavily on these lakes for its water supply.

It is said that lakes like Bhatsa only received rainfall of 8mm while Tansa and Modak Sagar received 2mm and 5mm of rainfall. On the other hand, Vihar lake observed 125mm of rainfall, while the Tulsi lake reportedly saw 90mm of rain.
As for the remaining water across the city’s lakes, Mumbai had around 3.73 lakh million litres left as of the most recent figures, while the stock was at 7.06 lakh million litres on July 16, 2019.
This indicates a steep fall in the lakes’ water supply, echoing previous concerns of a potential water shortage. However, civic officials have previously mentioned that there is enough water supply to last 42 days (as of June 22).
