Mumbai Lake Water Stock Touches 95.9 Per Cent Capacity Across Seven Reservoirs

Mumbai's water stock in the seven lakes supplying the city reached 95.90 per cent of useful capacity as of 6 am on August 31, 2026, according to data released by the Hydraulic Engineer's Department.

The seven reservoirs collectively held 13,88,054 million litres (ML) of water against a total live storage capacity of 14,47,363 ML. The recorded level was marginally lower than the 95.93 per cent reported the previous day.

Among the individual reservoirs, Vehar remained at 100 per cent useful capacity, while Modak Sagar and Tulsi were also nearly full at 99.99 per cent and 97.71 per cent, respectively. Tansa stood at 98.99 per cent, Middle Vaitarna recorded 98.18 per cent, Bhatsa stood at 95.83 per cent, and Upper Vaitarna was at 89.76 per cent.

Rainfall remained minimal across the catchment areas during the 24-hour window leading up to 6 am on Monday. Upper Vaitarna recorded 5 mm of rainfall, while Modak Sagar received 3 mm. Tansa, Middle Vaitarna, Bhatsa, Vehar, and Tulsi recorded no rainfall during the same period.

Earlier in the monsoon season, several lakes had already breached full capacity. Vehar and Tulsi began overflowing on July 7, followed by Tansa on July 22 and Modak Sagar on July 23.

The current water reserve places Mumbai in a comfortable supply position as August concludes, with overall storage holding significantly higher than levels typically observed toward the close of the monsoon season.

Alongside the reservoir status, the India Meteorological Department forecast light to moderate rain and thundershowers for Mumbai on Monday, with no weather alerts issued for the week. Isolated areas could experience moderate to heavy spells accompanied by wind gusts reaching 50 to 60 kmph. The city's maximum temperature was expected to reach 33°C, with a minimum of 30°C and an Air Quality Index reading of 17, placing it in the 'Good' category.
