Chetput lake is a lake spread over 15 acres in Chetput, Chennai, India. It is located to the north of Chetput Railway Station. It is the only existing lake at the centre of the city. Of the total area of the lake, the waterbody is spread across nearly 9 acres. An anglers club was functioning till the 1940s in the lake, whose members visited the small island in the midst of the waterbody for fishing.
In recent years, the lake has been heavily encroached upon, particularly near the Chetpet railway station. There have been many plans to rejuvenate Chetpet lake since the mid-1990s, including developing a boat club, an aquarium, seafood stall and fish court besides a walkway around the waterbody. The last attempt to save the lake was in 2005, when the state environment department identified it Along with 12 other lakes of Greater Chennai area for an eco-restoration project.
The CPR Environmental Education Centre conducted a detailed survey, and based on that, the state government appointed the Tamil Nadu Urban Infrastructure Finance Services Limited to prepare a project report. The State government had sanctioned 4 million to clean the overgrown water hyacinth and desilt the lake in 2007-2008. A building to house a stall of the Fisheries Development Corporation is also coming up by the side of the lake.
