Mumbai Rains: City's Water Stock Rises To 81.86% As All 7 Lakes Show Steady Rise Amid Monsoon

Mumbai: The city’s water stock has reached 81.86 per cent of its total capacity as per data released by the Hydraulic Engineer’s Department at 6:00 am on Saturday, July 19. The combined useful content in all seven lakes supplying water to Mumbai stands at 11,84,796 million litres, a significant improvement over last year’s 5,67,778 million litres on the same date.

Modak Sagar Lake Overflows

Among the lakes, Modak Sagar already begun to overflow as of July 9, reaching 100 per cent capacity with 1,58.3 mm of total rainfall received so far this monsoon. With a current water level of 163.08 metres, it holds 1,28,910 million litres of useful content. The overflow is a positive sign, reflecting strong inflows from recent rainfall.

Middle Vaitarna currently stores the highest volume of water at 1,80,823 million litres, with its level at 282.70 metres. It showed a rise of 0.23 metres in the last 24 hours. The lake has received 1,743 mm of rainfall this season, the highest among all reservoirs.

Upper Vaitarna follows closely, with 1,73,014 million litres of useful content at a level of 601.83 metres. However, the lake showed a slight drop of 0.04 metres since the last report. It has received 1,097 mm of rainfall so far.

Tansa and Bhatsa are also showing promising figures. Tansa stands at 132,359 million litres (91.23 per cent of its useful content), while Bhatsa holds 5,51,229 million litres with a 0.20-metre rise since the previous day. Bhatsa has received 1,483 mm of rainfall, indicating healthy catchment inflows.

Meanwhile, Vihar and Tulsi, the smaller lakes, contribute relatively less but have seen steady rain. Vihar stands at 14,674 million litres, and Tulsi at 4,327 million litres.

The BMC also confirmed that Upper Vaitarna began releasing water on July 5, while Middle Vaitarna’s gates were opened on July 17. The surge in water stock has eased concerns about water supply in Mumbai for the coming months.

With reservoirs nearing full capacity, the civic body is optimistic about uninterrupted water supply, provided rainfall continues consistently through the rest of the monsoon.
