Mumbai Water Stock in Seven Lakes Reaches 95.22 Per Cent Capacity

Useful water stock across the seven reservoirs supplying Mumbai reached 95.22 per cent of their total live storage capacity as of 6 am on Sunday, August 23, 2026. According to the latest report from the Hydraulic Engineer’s Department, the water content increased by 0.53 percentage points from the previous day's figure of 94.69 per cent.

The combined useful water content in the city’s seven reservoirs stood at 13,78,143 million litres against a total live storage capacity of 14,47,363 million litres.

Among the individual reservoirs, Modak Sagar and Vehar have reached 100 per cent of their useful storage capacity. Tansa is filled to 99.34 per cent, while Tulsi stands at 99.35 per cent. Middle Vaitarna recorded 95.29 per cent of its useful capacity, Bhatsa is at 95.14 per cent, and Upper Vaitarna stands at 89.32 per cent.

The steady rise in lake levels has been supported by sustained rainfall in the catchment areas. On Sunday, Upper Vaitarna received 45 mm of rain, Tulsi recorded 22 mm, Modak Sagar saw 20 mm, and Bhatsa logged 19 mm. Middle Vaitarna recorded 16 mm, Tansa received 14 mm, and Vehar recorded 9 mm of rainfall.

Four of the seven lakes have already overflowed earlier this monsoon season. Civic records show that Vehar and Tulsi both began overflowing on July 7, followed by Tansa on July 22 and Modak Sagar on July 23.

The Hydraulic Engineer’s Department continues to monitor reservoir levels, inflows, and dam operations across all catchment areas as the monsoon progresses.
