Although four out of seven lakes have already overflowed, Upper Vaitarna, one of the largest lakes, remains below the halfway mark. Additionally, minimal rain has been reported in all seven lakes, leaving the combined water stock nearly unchanged over the past three days.

When the lake levels dropped below 7 per cent, the BMC began using reserve water from Upper Vaitarna and Bhatsa lakes in the first week of June, extracting 48,432 million litres from below the lowest drawable level (LDL).
