Tulsi Lake in Mumbai Overflows: Reservoirs at 90% Capacity After Heavy Rains
Mumbai's Tulsi Lake, one of the seven reservoirs supplying the city with drinking water, has overflowed following heavy rains. The lake, located in the Sanjay Gandhi National Park, started overflowing on Saturday, adding to the water stock in the city's reservoirs, which are now over 90% full.

The Tulsi lake, situated in the Sanjay Gandhi National Park in suburban Mumbai, started overflowing at around 6.45 am on Saturday, the official said. The Sanjay Gandhi National Park is a prominent wildlife sanctuary and a significant green lung for the bustling city of Mumbai.
The seven reservoirs, which supply water to Mumbai, have more than 90% water stock now, the official from the Brihanmumbai Municipal Corporation (BMC) said. The BMC is the governing body responsible for the civic infrastructure and administration of the city of Mumbai.
Tulsi is the third reservoir which has overflowed after the Tansa and Modak Sagar dams, due to heavy rains in their catchment areas. This year, the Tulsi lake overflowed almost 26 days later compared to last year, when it became full on July 20, the official said.
Tulsi is the smallest of the seven reservoirs that supply potable water to Mumbai and has a storage capacity of 8,046 million litres. The city gets 18 million litres of water from the lake every day. "The catchment area of the lake has been receiving rainfall in the last few days, as a result of which the lake overflowed on Saturday," the civic official said.
When the Tulsi lake overflows, its water gets channeled into the Vihar lake, which has not yet reached its maximum capacity. The Vihar lake is another important water body in Mumbai, contributing significantly to the city's water supply.
The Powai lake, another reservoir located in the heart of Mumbai, started overflowing in June, but its water is not used for drinking purposes. Apart from Tulsi and Vihar, the metropolis receives water from the Bhatsa, Tansa, Lower and Middle Vaitarna reservoirs, all located in neighboring Thane district, and the Upper Vaitarna dam in Nashik district.
The overflow of these reservoirs is a positive sign for the city's water management, ensuring a steady supply of drinking water during the monsoon season and beyond. The BMC continues to monitor the water levels and manage the distribution to meet the needs of Mumbai's residents.
