Mumbai's water stock has seen a notable decrease, with the seven lakes supplying the city now recording a useful live storage level of 94.57% as of 6 AM. This figure reflects a drop of 0.34 percentage points from the previous day, when the level stood at 94.91%. According to the Brihanmumbai Municipal Corporation (BMC) Hydraulic Engineer’s Department, the total useful live storage across the seven reservoirs currently stands at 13,68,827 million litres (ML), compared to their combined capacity of 14,47,363 ML.
The decline in water stock is attributed to largely dry conditions across the catchment areas, with the report indicating no significant rainfall in the last 24 hours. After experiencing high levels during the monsoon season, the overall water stock has been fluctuating, raising concerns about Mumbai’s water supply as the dry season progresses.
- Upper Vaitarna lake — currently at 96.60% of its useful live storage, remains one of the better-performing reservoirs.
- Modak Sagar — which is critical for the city's water supply, stands at 70.36%, indicating a significant drop.
- Bhatsa lake — a key contributor to Mumbai’s water needs, is at 97.05%, while Vihar lake is fully stocked at 100%.
- Tulsi lake — at 97.40%, also contributes positively to the overall water levels.
Despite the recent decline, the overall water stock remains above 94% of the combined useful live storage capacity of the reservoirs. However, the current levels are lower than previous years, with 14,33,480 ML recorded during the same period in 2025 and 14,31,147 ML in 2024. This trend raises concerns about the availability of water as the city heads towards a potentially dry spell.
On the weather front, Mumbai experienced hot and humid conditions on this day, with the overall Air Quality Index (AQI) rising to 172, categorized as 'Poor'. The India Meteorological Department (IMD) has forecasted generally clear skies with a maximum temperature reaching 33°C, while the minimum temperature recorded was 28°C. With the southwest monsoon officially withdrawn, limited rainfall and continued humid conditions are anticipated in the coming days, further stressing the city's water resources.
