Mumbai’s seven lakes reach 97.48% of usable capacity after catchment rain

Mumbai’s seven water-supply lakes held 1,410,895 million litres at 6am on September 14, taking the city’s stock to 97.48% of their combined useful capacity of 1,447,363 million litres.

The level rose from 96.41% a day earlier after rain across the catchments. Vehar and Tulsi were at 100% capacity, with 27,698 ML and 8,046 ML respectively. Bhatsa, Mumbai’s largest water source, held 711,824 ML, or 99.27% of capacity, after 65mm of rain in its catchment over 24 hours.

Middle Vaitarna stood at 96.92%, Tansa at 98.69%, Modak Sagar at 93.82% and Upper Vaitarna at 93.20%. Four lakes — Vehar, Tulsi, Tansa and Modak Sagar — have overflowed during this monsoon.

Despite the rise, the combined stock remains below the level recorded on September 14 in the previous two years: 98.70% in 2025 and 98.56% in 2024. Rain and gusty conditions are also expected in Mumbai on Tuesday, as outlined in the latest city forecast.
