Mumbai's seven key lakes held just 7.18% of their useful live storage capacity as of 6 am on Wednesday, July 1, according to the BMC's daily water stock report. The total water stock stood at 1,03,871 million litres (ML), against the full capacity of 14,47,363 ML.
On the same date last year, storage levels were higher at 41.17%, while in 2024 they were marginally lower at 5.46%. Despite an improvement year-on-year, overall reserves remain below normal with the monsoon yet to fully set in. The lakes supplying Mumbai's water are Bhatsa, Upper Vaitarna, Middle Vaitarna, Tansa, Modak Sagar, Vihar and Tulsi.
