Mumbai’s lake stock slips to 96.31% as Bhatsa catchment gets 26 mm rain

Mumbai’s seven lakes held 96.31% of their usable water capacity on October 1, with the combined stock at 13,93,939 million litres (ML), BMC data showed.

That is 4,783 ML lower than the 13,98,722 ML recorded on September 29. The reservoirs have nevertheless retained substantial post-monsoon reserves: Vehar was at 100% capacity, followed by Middle Vaitarna at 99.37%, Tulsi at 98.74% and Bhatsa at 98.43%.

Modak Sagar, the lowest-filled of the seven, stood at 79.80% and its level fell by 0.25 metres over 24 hours. Upper Vaitarna was at 96.60% and Tansa at 95.11%.

Bhatsa’s catchment received 26 mm of rain in the 24 hours ending at 6 am, the highest among the reservoirs. Tansa received 11 mm and Modak Sagar 6 mm; Vehar and Tulsi recorded no rain.

The current stock is below the position on October 1 in the previous two years, when the lakes were at 98.70% in 2025 and 99.37% in 2024. Mumbai’s reservoir stock had stood at 97.14% after a dry day in late September.
