Why is Tulsi Lake usually the first to overflow?

It has the smallest holding capacity (8,046 ML) and only a 6 sq km catchment, so even moderate rain fills it quickly.

Can the public visit Tulsi Lake?

No. It's inside the core zone of Sanjay Gandhi National Park; access is prohibited to protect water quality and wildlife.

Where does Tulsi's water go when it overflows?

Overflow drains directly into Vihar Lake downstream, topping up its neighbour's reserves during the monsoon.

About Tulsi Lake

At 8,046 ML, Tulsi is the smallest lake in the system, but it reliably overflows before any of the others — a 6 sq km catchment fills fast. Built in 1879, it too sits inside Sanjay Gandhi National Park. When it spills, water flows directly into neighbouring Vihar Lake. The ancient Kanheri Caves are a short walk from its perimeter.
