Managed by the Brihanmumbai Municipal Corporation (BMC), these water sources form the backbone of Mumbai’s daily water supply. Interestingly, only two of the seven lakes, Vihar and Tulsi, are located within Mumbai’s boundaries, while the remaining five are situated in the neighbouring districts of Thane, Palghar and Nashik regions

Heavy rainfall in Mumbai's lake catchment areas pushed reservoir storage up by nearly 12 percentage points in 24 hours, but the BMC has retained the 10 per cent water cut.
