Two boys drowned in a lake at Suraikulam village near Arcot town in Tiruvannamalai on Friday. Police said the deceased has been identified as N. Nithish (6) and his relative T. Veeravel (8).

Located near Manali in North Chennai, India, the lake sits in an area heavily shaped by agricultural activity, which has led to its waters becoming polluted and unhealthy. But that's about to change.
