Tulsi Lake, situated near the Sanjay Gandhi National Park, holds the distinction of being the second-largest lake in the Mumbai city of Maharashtra. It is a fresh water lake, which serves as the source of water for some of the parts of the city. Located in the northern side of Bombay, the lake has an overflow level of approximately 139.17 m (456.6 feet). The main source of water for the Vihar Lake is the rain water, which is received during the monsoon season of Mumbai that lasts from June to September.
The excessive rainwater that is received by the lake during monsoons is
absorbed by the catchment area provided by the Powai-Kanheri Hills.
Vihar Lake was constructed by damming River Tasso. The foundation plan
of the dam was laid down in the year 1872 and the lake was completely
built by 1897. The cost of construction was somewhere around 40 lakh
rupees (Rs. 4,000,000). One of the major attractions of the Vihar Lake
comprises of the fresh water crocodiles that seem to inhabit its waters.
The lake is not open for public viewing.
