The seven lakes that supply drinking water to Mumbai collectively contained 1,35,139 million litres (ML) of water, or 9.34% of their total live storage capacity, according to the Brihanmumbai Municipal Corporation's (BMC) reservoir status report released at 6:00 am on Friday, June 19, 2026.
The latest reservoir status report shows that no rainfall was recorded in the catchment areas over the past 24 hours, with water levels in several key lakes continuing to remain under pressure.
Among the major reservoirs, Bhatsa, Mumbai's largest source of drinking water, contained 61,888 million litres of water, while Middle Vaitarna held 20,008 million litres. Modak Sagar stored 34,280 million litres, Tansa 5,618 million litres, Vihar 11,532 million litres, and Tulsi 1,813 million litres.
The report noted that Upper Vaitarna's water level remains below the Lower Draw Down Level (LDL), resulting in its useful storage being considered zero for operational purposes.
The combined stock in the Upper Vaitarna, Modak Sagar, Tansa and Middle Vaitarna system stood at 59,906 million litres, representing 8.62 per cent of the group's total storage capacity. Bhatsa reservoir alone accounted for 61,888 million litres, or 8.63 per cent of its live storage capacity.
The reservoir status comes amid concerns over delayed monsoon rainfall and declining water reserves. Mumbai's seven lakes had fallen below 10 per cent of total storage earlier this week, prompting the BMC to implement water conservation measures and monitor the situation closely.
