Mumbai Rains: Water Levels In City's 7 Lakes Rise To Nearly 74% Amid Consistent Showers

Mumbai: The city’s water reserves have received a significant boost, with the total lake storage touching 73.88 per cent of the total useful water capacity as of 6:00 am on Friday. According to the latest report from the BMC’s Hydraulic Engineer’s Department (Bhandup Complex), Mumbai’s seven lakes now collectively hold 10.69 lakh million litres of usable water.

This improvement comes as a relief following initial monsoon concerns. The rainfall over the catchment areas has steadily improved storage levels in major lakes, especially Modak Sagar, Middle Vaitarna, and Tansa. These lakes contribute significantly to the city’s daily water supply.

Details On Water Levels Across Lakes

Modak Sagar is currently filled to 100 per cent capacity with 1.28 lakh million litres in storage. Tansa is also nearing full storage at 79.13 per cent, with 1.14 lakh million litres. Upper Vaitarna is at 74.02 per cent, holding 1.68 lakh million litres. Middle Vaitarna, one of the biggest contributors, is at 92.87 per cent, containing 1.79 lakh million litres.

Bhatsa, which accounts for a large share of Mumbai’s water supply, has reached 64.21 per cent of its useful storage, translating to 4.60 lakh million litres. Vehar and Tulsi, though smaller in capacity, are storing 48.36 per cent and 49.79 per cent, respectively.

Massive Rise In Lake Water Levels Compared To Previous Year Data

Comparatively, on the same date in 2024, the total useful storage across lakes was just 22.26 per cent, or around 3.22 lakh million litres. This year’s figures show a marked improvement, easing the pressure on authorities and raising hopes for a stress-free supply through the season.

Rainfall over the catchment areas has been consistent. Bhatsa has received a total of 1,308 mm of rainfall so far. Modak Sagar has recorded 1,149 mm, Middle Vaitarna 1,590 mm and Tansa 1,326 mm. Tulsi and Upper Vaitarna have recorded 1,189 mm and 1,014 mm respectively. The Bhandup Complex reported 3 mm rainfall in the last 24 hours, with the season’s total now at 697 mm.

The report also noted recent operational developments. Upper Vaitarna began releasing water from July 5. Gates 1 and 5 of Middle Vaitarna were opened on July 7. Modak Sagar started overflowing on July 9, marking a key milestone for the season.

With all major lakes showing strong inflows and high rainfall in their catchment zones, Mumbai is on a secure path to meet its water needs in the coming months.
