As monsoon showers continue to drench Mumbai, the city’s seven major lakes — the primary sources of drinking water — have reached nearly 90% of their full capacity, offering a much-needed relief after concerns over low reserves earlier this year. The India Meteorological Department (IMD) has predicted more moderate to heavy rainfall through the coming week, likely pushing storage levels further toward the 100% mark.
🏞️ Mumbai’s Water Sources Almost Full
As of August 4, 2025, combined storage across Mumbai’s lakes — including Bhatsa, Tansa, Vihar, Tulsi, Upper Vaitarna, Middle Vaitarna, and Modak Sagar — stands at 12.5 lakh million litres, which is around 89.6% of total storage capacity.
This is a significant improvement compared to the same period last year, when the reservoirs were only around 75% full.
⛈️ More Rain Ahead – IMD Forecast
The IMD’s seven-day forecast for the Mumbai Metropolitan Region (MMR) suggests:
Heavy showers expected between August 5 and August 8
Orange Alert issued for isolated parts of Mumbai and Thane
High humidity and overcast skies likely to continue
This pattern is expected to boost water inflow into the reservoirs, especially Bhatsa and Upper Vaitarna, which account for the majority of the city’s daily water supply.
🚰 Why This Matters for Mumbai
Mumbai needs 14.5 lakh million litres of water storage by October every year to meet its year-round water requirement. With lakes nearly 90% full and rainfall still active, the city is now on track to avoid water cuts or restrictions this year.
Key benefits of full reservoir levels:
No summer water shortage in 2026
Steady supply to over 1.3 crore Mumbaikars
Reduced pressure on pumping systems and civic management
Boost for agriculture in outer suburban and rural areas linked to these lakes
🧾 Civic Measures in Place
The Brihanmumbai Municipal Corporation (BMC) has also confirmed:
Round-the-clock lake monitoring
Alerts for dam overflow situations
Desilting and floodwater management in vulnerable low-lying areas
No water cuts planned for the near term
The corporation has asked citizens to continue using water responsibly despite the improving situation.
🧭 Final Thoughts
After weeks of watching rain patterns closely, Mumbai can breathe a sigh of relief as its lakes inch toward full capacity. While more rain is forecasted, the key now lies in managing inflows smartly and ensuring urban flood preparedness as downpours continue.
For Mumbaikars, this is good news — a strong sign that the city may head into next summer without the dread of water scarcity.
