The historic Madurantakam lake in Chengalpattu district, one of Tamil Nadu's largest waterbodies, is nearing the final stages of a Rs 163-crore restoration project, with 95 percent of work completed.

Originally built in the 10th century by King Uthama Chozhan, the 4,752- acre lake has been a vital irrigation source for 2,853 acres of farmland across 36 villages. Decades of silt accumulation had drastically reduced its water-holding capacity, prompting repeated appeals from farmers and environmentalists. Restoration efforts began in 2022 following an initial Rs 120 crore allocation, with an additional Rs 43 crore later sanctioned for a 12-shuttered surplus sluice gate system. The automated gates, spanning 144 mtrs. and powered by electric motors, are currently undergoing successful trial runs, aided by northeast monsoon inflows.

Once completed, the lake’s capacity will rise from 694 to 1,000 million cubic ft., enhancing flood control, groundwater recharge, and paddy cultivation. The lake is expected to be fully operational by February 2026, restoring a vital agricultural lifeline.
