Mumbai: Mumbai’s water stock saw a rise following continuous showers across catchment areas, with the city’s seven lakes collectively holding over 13.09 lakh million litres (ML) of water as of Saturday, August 16, 2025. This amounts to around 90.16 per cent of their total storage capacity, offering major relief to the city’s water needs.
According to data released by the Hydraulic Engineer’s Department of the BMC, Upper Vaitarna, Modak Sagar, Tansa, Middle Vaitarna, Bhatsa, Vihar and Tulsi lakes have all recorded healthy levels, with some of them already near or at overflow marks. The collective storage last year on the same date was 14.39 lakh ML (93.23 per cent) while in 2023 it stood at 12.07 lakh ML (83.42 per cent).
Details On All Lake Levels
Among the major reservoirs, Bhatsa, which contributes the largest share to Mumbai’s supply, has a level of 139.06 metres with a live storage of 6.35 lakh ML, accounting for 88.65 per cent of its capacity. Tansa has reached 128.48 metres with 1.42 lakh ML in storage (98.08 per cent), while Modak Sagar is at 161.32 metres, holding 1.14 lakh ML (88.49 per cent). Middle Vaitarna stands at 283.69 metres with 1.86 lakh ML in storage (96.37 per cent).
The smaller lakes within city limits are already full or near capacity. Vihar lake, at 79.43 metres, is 87 per cent full, holding 24,098 ML, while Tulsi has touched 138.93 metres with 7,715 ML (95.88 per cent). Vihar received the highest rainfall in the past 24 hours with 120 mm, followed by Tulsi at 133 mm.
In terms of cumulative rainfall, Tulsi leads with 2,438 mm this season, followed closely by Modak Sagar (2,181 mm) and Bhatsa (1,943 mm). Vihar has recorded 1,422 mm so far, while Upper Vaitarna has received 1,460 mm.
Officials confirmed that Modak Sagar and Tansa dams have already begun overflowing, while all gates of Bhatsa and Middle Vaitarna were closed earlier this month to regulate supply. The steady rise in levels has assured that Mumbai is unlikely to face any water cuts in the coming months.
The BMC reported that the Bhandup water complex, which distributes supply across the city, received 152 mm rainfall in the past 24 hours, bringing the total seasonal rainfall to 1,595 mm. With reservoirs nearing full storage, civic authorities are optimistic about meeting the city’s water demand without disruption through the year.
