Mumbai Weather Update: Moderate Rain Expected as City Lakes Reach 88.76% Capacity

As per the IMD forecast, the Island City is most likely to experience intermittent moderate showers throughout the day, while cloudy conditions are expected to continue over Mumbai and adjoining suburban areas.

Rainfall recorded across Mumbai during the 24-hour period from 8 pm on August 5 to 8 am on August 6 remained comparatively low. The Island City recorded an average rainfall of 11.95 mm, while the Eastern Suburbs received 11.84 mm and the Western Suburbs recorded 12.63 mm of rainfall during the same period.

Authorities have advised commuters to remain updated on weather conditions, especially during high tide hours, as moderate rainfall may result in waterlogging in low-lying areas.

Meanwhile, Mumbai’s seven lakes, which supply drinking water to the city, collectively held 12,84,608 million litres of water, accounting for 88.76 per cent of their total live storage capacity, as of 6 am on Thursday, August 6, according to the Hydraulic Engineer's Department at the Bhandup Master Control Centre.

The current water stock remains higher than the same period last year, when the reservoirs contained 12,91,577 million litres, or 89.27 per cent of the total capacity. However, the lake levels are lower compared to 2024, when the reservoirs held 13,03,580 million litres, accounting for 90.07 per cent of the total live storage.

Among the seven reservoirs, Modak Sagar, Vihar and Tulsi continued to remain at 100 per cent live storage capacity, while Tansa stood at 99.42 per cent.

Middle Vaitarna recorded 91.99 per cent storage, Bhatsa, Mumbai’s largest reservoir, stood at 86.28 per cent, while Upper Vaitarna remained the lowest-filled lake with 78.83 per cent storage.

The current storage levels in individual lakes are as follows: Upper Vaitarna recorded 1,78,970 million litres (80.53 per cent), Modak Sagar recorded 1,28,925 million litres (100 per cent), Tansa recorded 1,44,240 million litres (99.14 per cent), Middle Vaitarna recorded 1,78,035 million litres (91.05 per cent), Bhatsa recorded 6,18,694 million litres (87.64 per cent), Vihar recorded 27,698 million litres (100 per cent), and Tulsi recorded 8,046 million litres (100 per cent).
