Monsoon Tracker Update July 1, 2026: Helicopter services suspended due to adverse weather conditions in Kedarnath Dham Yatra

Amid heavy rains across Mumbai, Powai Lake in the city’s eastern suburbs began to overflow on the morning of July 1, even as stocks in the seven reservoirs supplying the metropolis with drinking water remained abysmal compared to last year.

The Brihanmumbai Municipal Corporation (BMC) said Powai Lake, one of the key man-made lakes in its jurisdiction, started overflowing around 5.30 am. “With a water retention capacity of 545 million litres, water from the lake is used only for industrial purposes,” the BMC said in a post on X.

Surplus water from the lake flows into the Mithi River, which flows into the Arabian Sea at Mahim.

Powai Lake overflowed on June 19 last year. This year’s overflow was delayed due to the late onset of monsoon in Mumbai.

When the lake is full, its water area is about 2.23 km², while its catchment area covers 6.61 km², the civic body said. Located about 27 km from the BMC headquarters, Powai Lake was built in 1890 at a cost of ₹40 lakh.

Inventory significantly low in 7 tanks

Meanwhile, water storage in the seven reservoirs that supply drinking water to Mumbai stood at 7.18% of their total capacity at 6 am on July 1, compared to 41.17% on July 1, 2025.

Mumbai receives 3,850 million liters (385 million liters) of water every day from Bhatsa, Upper Vaitarna, Middle Vaitarna, Tansa, Modak Sagar, Vihar and Tulsi lakes.
