🚰 Report of water stock in the seven lakes, supplying water to Mumbai, till 6am today.#MumbaiRains#MyBMCUpdates pic.twitter.com/EnC73DBIGHAmid the ongoing heavy monsoon rains in Mumbai and surrounding areas, these lakes have seen a continuous rise in their water levels. Middle Vaitarna lake was at 93.47% capacity, holding 1,80,890 million litres of water. The lake's height increased two metres alone in the past 24 hours, the BMC data showed.
Following the surge in water levels in Middle Vaitarna to nearly 90% on Monday, the BMC opened three of its dam gates to allow water to be stored in Modak Sagar (lower reservoir). This contributed to Modak Sagar's capacity being increased to over 94.82%, the BMC's latest data showed. It also received 25 mm of rain in the last 24 hours. As of now, all lakes except Vehar (47.68%) and Tulsi (46.97%) are above 60% capacity.
🔹The Brihanmumbai Municipal Corporation (BMC) supplies water through seven major reservoirs, one of which – the ‘Shivsena Pramukh Hinduhrudaysamrat Balasaheb Thackeray Middle Vaitarna Reservoir' is currently around 90% full as of 7th July 2025.

Meanwhile, the India Meteorological Department (IMD) has predicted moderate to very heavy rainfall in Maharashtra, Goa and the Konkan region during the next seven days. With more rainfall predicted this week, Modak Sagar and Middle Vaitarna may start overflowing while other lakes are likely to see a surge in water levels.
