About Tulsi Lake
Tulsi Lake is a freshwater reservoir located within Sanjay Gandhi National Park in northern Mumbai. Constructed between 1872 and 1897 by damming the River Tasso, it serves as a critical potable water source for the city. It is the second-largest lake in Mumbai and lies entirely within protected forest land. Access is restricted and regulated by park authorities due to its role in water supply and wildlife habitat protection.

History of Tulsi Lake
The plan to create Tulsi Lake was conceived in 1872 and construction completed in 1897 to augment Mumbai's water supply after Vihar Lake proved insufficient. It was built by damming the River Tasso and redirecting flow to Vihar Lake at a cost of Rs 40 lakhs. The lake has served as a backup potable water source for over a century.
Culture & Context
Tulsi Lake holds cultural value for communities in Mumbai's northern suburbs and is named after the abundant tulsi (holy basil) plants in the area. As a protected water body within SGNP, it represents the intersection of urban water security and forest conservation in Mumbai's environmental heritage.
