According to the Brihanmumbai Municipal Corporation (BMC), the lakes together held 10,09,432 million litres of water on Wednesday, which is around 69.74% of their total storage capacity of 14.47 lakh million litres.
Although storage has climbed to nearly 70%, reservoir levels remain below last year's 86.88% for the same period. Continued monsoon rainfall over the next few days will be important for ensuring sufficient water supply through the coming months.
