Mumbai Water Stock Reaches 95.87% Across Seven Reservoirs

Mumbai's overall water stock in the seven supplying reservoirs rose marginally to 95.87 per cent of capacity on the morning of August 28, according to data released by the Brihanmumbai Municipal Corporation's Hydraulic Engineer's Department.

As of 6 am on August 28, the seven lakes supplying water to Mumbai recorded a total of 13,87,534 million litres (ML) of useful water content. The total useful live storage capacity across all seven reservoirs stands at 14,47,363 ML.

The measurement marked a slight increase compared to August 27, when overall storage stood at 95.84 per cent. The consistent levels indicate that the city's water reserves remain healthy heading into the latter stages of the monsoon season.

Among the individual reservoirs, both Modak Sagar and Vehar remained at 100 per cent of their useful storage capacity. Tansa recorded a level of 98.37 per cent, while Tulsi reached 98.33 per cent. Middle Vaitarna held 97.57 per cent of its useful storage, and Bhatsa was recorded at 95.91 per cent. Upper Vaitarna maintained the lowest level among the seven lakes at 89.96 per cent.

In terms of volume, Bhatsa held the largest share of useful water at 6,87,681 ML. The combined useful water content across Upper Vaitarna, Tansa, and Middle Vaitarna stood at 6,64,424 ML. Vehar held 27,698 ML of useful water content, while Tulsi recorded 7,911 ML.

The municipal corporation's records show that several lakes began overflowing during July as a result of sustained rainfall. Vehar and Tulsi both began overflowing on July 7, while Tansa started overflowing on July 22. Modak Sagar began overflowing on July 23.

In management operations earlier in the monsoon, the Middle Vaitarna WSCPO gate was closed on July 6. The release of water from Upper Vaitarna was also halted starting from July 6.

The seven lakes serve as the primary source of water supply for Mumbai, with ongoing inflows continuing to support the city's overall storage.
