Tulsi Lake is a fresh water lake in northern Mumbai. It is stated to be the second largest lake in Mumbai and supplies part of the city’s potable water. This is one of the three lakes located in the Salsette Island; the other two being Powai Lake and Vihar Lake.
Tulsi lake, located within Sanjay Gandhi National Park (SGNP), is usually the first to overflow. The other lakes – Vihar, Upper Vaitarna, Middle Vaitarna, Modak Sagar, Tansa, and Bhatsa – are in Thane and Palghar districts. The seven lakes can store up to 14.47 lakh million litres of water and bifurcate into two systems – the Vaitarna system, which supplies water to the western suburbs and the island city; and the Bhatsa system, which supplies water to the eastern suburbs. Three weeks ago, Powai lake had overflowed, but it supplies water only for industrial purposes.
