Mumbai Water Stock at 88.41%

Mumbai's seven lakes, which supply drinking water to the city, recorded a marginal decline in overall water stock over the last 24 hours.

The combined water stock stood at 12,79,566 million litres, or 88.41 per cent of the total useful storage capacity, at 6 am on Saturday, August 1, 2026.

On Friday, the reservoir stock was 88.58 per cent, indicating a 0.17 percentage point decline in the past 24 hours.

Among the major reservoirs, Bhatsa, Mumbai's largest source of drinking water, received 16 mm rainfall during the last 24 hours and is currently at 87 per cent of its useful storage capacity.

Upper Vaitarna received the highest rainfall at 160 mm, while Middle Vaitarna recorded 47 mm, Modak Sagar 39 mm, Tulsi 16 mm, Vihar 15 mm and Tansa 18 mm.

Despite the slight dip in overall storage, three lakes continue to remain full. Modak Sagar is at 100 per cent capacity, Vihar is also at 100 per cent, while Tulsi stands at 99.66 per cent.

Tansa is at 98.77 per cent, Middle Vaitarna at 92.37 per cent, and Upper Vaitarna at 74.45 per cent.

The BMC also noted that Vihar Lake began overflowing on July 7, followed by Tulsi Lake later the same day, Tansa Dam on July 22, and Modak Sagar Dam on July 23, contributing to Mumbai's water security for the ongoing year.

With reservoir levels remaining above 88 per cent, Mumbai's water reserves continue to be in a comfortable position as the monsoon season progresses.

The city's water stock is closely monitored by the Hydraulic Engineer's Department, which provides updates on the water levels in the lakes.

The department's data shows that the water stock in the lakes has been steadily increasing over the past few weeks, thanks to the heavy rainfall in the catchment areas.

The comfortable water stock position is a relief for the city, which has been facing water scarcity issues in recent years.

The BMC has been taking steps to ensure that the city's water needs are met, including implementing water conservation measures and increasing the capacity of the lakes.

The current water stock position is a testament to the effectiveness of these measures, and the city can breathe a sigh of relief as the monsoon season continues.
