Mumbai’s Lakes Almost Full After Heavy Rain; Water Levels Touch 99.46 Per Cent

Mumbai’s drinking water reserves have received a significant boost thanks to steady rainfall in the catchment areas. As per the details posted on X, the Brihanmumbai Municipal Corporation (BMC) confirmed that the combined stock in the seven lakes supplying the city now stands at 99.46 per cent.

According to data shared on Sunday, the total live storage in these reservoirs has reached 1,439,588 million litres, a reassuring sign for the city as it moves deeper into the monsoon season.

The seven lakes, Upper Vaitarna, Modak Sagar, Tansa, Middle Vaitarna, Bhatsa, Vehar and Tulsi, form the backbone of Mumbai’s daily water supply. Among them, Modak Sagar and Tulsi have both touched 100 per cent capacity, while Vihar has also filled completely with 27,698 million litres.

Upper Vaitarna is currently at 99.58 per cent with 226,083 million litres, while Tansa holds 144,946 million litres, also at 99.58 per cent. Middle Vaitarna has 190,157 million litres in storage, equal to 98.56 per cent, and Bhatsa, the city’s largest contributor, is at 99.35 per cent with 712,373 million litres.

In the last 24 hours, water levels across the lakes have risen slightly by 0.09 to 0.17 metres, supported by steady rainfall. The Bhandup Complex, which monitors lake levels, recorded 107 mm of rain in the same period. Tulsi Lake received the highest rainfall at 106 mm, followed by Upper Vaitarna with 72 mm and Modak Sagar with 96 mm. Bhatsa and Vihar also saw healthy showers of 58 mm and 53 mm respectively.

With reservoirs nearing their peak, several lakes have begun releasing water over recent weeks. Upper Vaitarna and Middle Vaitarna started discharging in August, while Modak Sagar and Tansa overflowed earlier in July. Bhatsa, Tulsi and Vihar also reached capacity by mid-August.

For residents, the near-full lakes bring relief and reassurance of a steady water supply in the months ahead.
