Overview
- The seven lakes held 7,03,260 million litres of water, equal to 48.59% of live storage, according to the Hydraulic Engineer's Department report recorded at 6 am Thursday.
- Vihar and Tulsi lakes reached full capacity and began overflowing late on July 7, and several other reservoirs rose sharply after three days of heavy catchment rain.
- Civic officials have kept a citywide 10% water cut in force and will consider lifting it only after every one of the seven lakes overflows and rainfall remains steady through the rest of July.
- Mumbai's supply depends on the seven lakes feeding two treatment and distribution networks, with Bhatsa the largest source and the BMC supplying about 4,100 million litres a day.
- Officials say the recent inflows reduce immediate pressure on stocks but that the city still needs roughly 14.47 lakh million litres by October 1 for year‑round security so they will reassess levels at the end of the month.
