Mumbai Lakes Nearly 75% Full Amid Heavy Rains, City Unlikely to Face Water Cuts

Mumbai: The seven lakes supplying water to Mumbai have collectively reached 74.47% of their total useful live storage capacity, as per the latest data released by the BMC’s Hydraulic Engineer’s Department on July 12, 2025.
This marks a dramatic improvement compared to last year, when storage levels stood at just 27.65% on the same date.
The total combined storage now stands at 10.77 lakh million litres (ML) out of the total 14.47 lakh ML capacity. The Vaitarna group of reservoirs—Upper Vaitarna, Modak Sagar, Tansa, and Middle Vaitarna—together hold 5.92 lakh ML of water, which is 85.56% of their capacity.
Modak Sagar has already reached 100% and began overflowing on July 9. Middle Vaitarna stands at 92.87%, Tansa at 82.34%, and Upper Vaitarna at 74.89%. Among the smaller lakes, Tulsi is at 93.63% while Vihar is at 61.90%.
Bhatsa, the city’s largest source, currently holds 4.66 lakh ML out of its 7.19 lakh ML capacity—65.01% filled.
Recent rainfall in the catchment areas has significantly boosted water levels. On July 11 alone, Modak Sagar received 34 mm of rainfall, Tansa 22 mm, Bhatsa 23 mm, while Upper Vaitarna recorded none. The Bhandup Complex logged 15 mm of rain in the past 24 hours, pushing its seasonal total to 712 mm.
Given the healthy stock across reservoirs, the BMC is not expected to implement any water cuts soon. However, officials will continue to regulate water releases to prevent downstream flooding.
The current situation points to a secure water supply for Mumbai for the rest of the year.
