Mumbai has received heavy rains over the past few days, bringing much-needed relief to the city and significantly boosting the water levels in its major lakes. As of September 23, 2025, the city’s seven major lakes are at a combined capacity of 99.51%, marking a significant milestone in the monsoon season.
Current Water Levels
Vihar, Modak Sagar, Tansa, and Tulsi Lakes have already overflowed, reflecting the intensity of recent rainfall.
Upper Vaitarna, Middle Vaitarna, and Bhatsa Lakes are still slightly below full capacity but have shown steady increases due to continued rain.
The Brihanmumbai Municipal Corporation (BMC) reports that over 50 mm of rainfall in the past 24 hours has contributed to these rising levels.
Will the Lakes Reach 100%?
Given the current rainfall trends and overflowing lakes, it is highly likely that Mumbai’s remaining lakes will reach full capacity in the coming days. While some lakes are still filling, the continuous moderate rainfall ensures that water levels are steadily approaching 100%.
