Mumbai Lake Levels Reach 95.87 Per Cent With 13.87 Lakh Million Litres in Storage

Water stock across the seven reservoirs supplying Mumbai stood at 95.87 per cent of total capacity as of 6 am on September 1, 2026, according to data released by the Hydraulic Engineer’s Department. The overall stock recorded a marginal decline from the 95.90 per cent reported on the previous day.

The seven lakes currently hold 13,87,618 million litres (ML) of useful water against their combined live storage capacity of 14,47,363 ML. The storage level keeps the city's water supply in a comfortable position as the monsoon season approaches its final phase.

Several reservoirs had overflowed earlier in the season following heavy rains. Vehar and Tulsi began overflowing on July 7, while Tansa started overflowing on July 22 and Modak Sagar on July 23.

Rainfall in the catchment areas remained relatively light during the 24 hours leading up to 6 am. Upper Vaitarna received 10 mm of rainfall, while Middle Vaitarna and Tulsi each recorded 5 mm. Vehar logged 4 mm, Modak Sagar recorded 3 mm, and Bhatsa received 2 mm. Tansa recorded no rainfall during the 24-hour period.
