🚰 Report of water stock in the seven lakes, supplying water to Mumbai, till 6am today.#MumbaiRains#MyBMCUpdates pic.twitter.com/PU5nlg9EnxAccording to data from the Brihanmumbai Municipal Corporation (BMC), the city's lakes reached full capacity on September 5 in both 2022 and 2023, which marked the earliest in the past decade. In those years, the overall water stock had reached 70% by the end of July. This year, with storage already at 80% by mid-July, the water levels in all seven lakes could potentially reach full capacity by the second half of August, an Indian Express report added, citing the BMC data.
In 2024, the lakes reached the 70% mark on July 24, while the full capacity was reached on Sept. 29. The latest data shared by the BMC shows that all lakes are currently above 50% capacity. While Modak Sagar became the first lake to be completely filled this year, Upper Vaitarna (77%), Middle Vaitarna (92%) and Tansa (89.19%) are also nearing their full capacity. The continuous surge in water levels of these lakes is due to the early arrival of the monsoon in Mumbai and the surrounding areas. As a result, the city is unlikely to face any water cuts next summer.
This year, the monsoon arrived in Mumbai on May 27, marking its earliest arrival since 1950, according to the India Meteorological Department (IMD). The previous earliest date was May 29.
