Mumbai Lakes Near Full as BMC Reviews Potential Water Cut
Mumbai gets most of its water from seven lakes.
These lakes are currently almost completely full, holding about 98 per cent of their capacity.
However, the city has received little rain recently.
Officials worry that hotter weather could make more water evaporate.
They think the stored water may last only until May.
The state government has asked officials to plan for water through August.
The city may review a 10 per cent water cut next month.
The cut will not be withdrawn unless the stock reaches 14.47 lakh million litres on October 1.
Mumbai’s seven water-supplying lakes are 98 per cent full as of September 22, 2026.
Their combined stock is 14.19 lakh million litres against total reservoir capacity.
Officials fear the supply may last only until May, while the state wants planning through August.
The Brihanmumbai Municipal Corporation will decide next month whether to impose a 10 per cent water cut.
Higher temperatures linked to El Niño could increase evaporation losses after the dry August and September.
