Mumbai Rains: Lake Levels See Slight Rise To Nearly 36% As City Receives Light Showers

Mumbai: Mumbai’s water stock continues to rise steadily as consistent rainfall boosts the levels in the city's key lakes. According to the latest report from the Hydraulic Engineer’s Department (Bhandup Complex) released at 6:00 am on Thursday, June 26, 2025, the combined water stock in Mumbai’s lakes stands at 5,20,614 million litres, about 35.97 per cent of the total required annual capacity of 14.47 lakh million litres.

The water levels gained just a slight increase as consistent yet light showers were recorded across all seven lake zones over the past 24 hours. The Bhandup Complex recorded 10 mm of rain today, bringing the season’s cumulative total to 451 mm.

Bhatsa Leads With Highest Storage

Bhatsa Lake, which plays a crucial role in Mumbai’s water supply, has seen a significant rise and now holds 2,10,972 million litres of useful content, the highest among all lakes. It received 5 mm rainfall in the last 24 hours and has recorded a total seasonal rainfall of 695 mm so far.

Upper Vaitarna & Modak Sagar Also Show Gains

Upper Vaitarna’s water level rose by 0.12 meters in the last 24 hours, reaching 599.15 meters. Its current useful storage is at 94,587 million litres. It received 18 mm of rainfall since yesterday and has recorded a cumulative seasonal rainfall of 376 mm.

Modak Sagar saw a slight dip of 0.04 meters but still maintains 69,732 million litres in useful content. The lake received 4 mm rainfall in the past 24 hours, adding to its seasonal tally of 774 mm, the highest among all lakes.

Tansa, Middle Vaitarna Witness Modest Gains

Tansa’s level rose by 0.08 meters, holding 57,848 million litres of water. Middle Vaitarna also recorded a 0.61-meter rise, with useful content reaching 78,420 million litres.

Smaller Lakes Remain Steady

Vihar and Tulsi, the smaller lakes located within the city limits, recorded slight increases. Vihar rose by 0.01 meters, now storing 31,362 million litres, while Tulsi added 0.01 meters with 3,226 million litres in useful content.

While the current water stock is promising, civic officials remain cautious. The monsoon has made a timely impact, but over 60 per cent of the required annual storage still needs to be met. Authorities are closely monitoring the situation to ensure the city’s uninterrupted water supply in the coming months.
