Chennai, Oct 22 (NationPress) As heavy rainfall continues to impact the Chennai area, the Water Resources Department (WRD) has issued urgent alerts for residents near the Adyar and Kosasthalaiyar Rivers. This action comes as the discharge rates from both Chembarambakkam and Poondi reservoirs have been significantly raised to ensure the safety of these dams.
At Chembarambakkam Lake in the Kancheepuram district, the outflow has been escalated to 500 cubic feet per second (cusecs), a substantial increase from the earlier precautionary release of 100 cusecs initiated on October 21. Officials reported that the inflow to the reservoir reached 2,170 cusecs by 6 a.m., significantly rising after overnight rains.
This lake, which has a total capacity of 3,645 million cubic feet (mcft) and a maximum depth of 24 feet, recorded a storage level of 20.84 feet (2,815 mcft), up from 18.52 feet the previous week.
The WRD engineers stated that this release is in line with standard flood management practices to keep water levels within the safe 21-foot limit. Residents in low-lying areas downstream, such as Sirukalathur, Kavanur, Kundrathur, Tirumudivakkam, Vazhudiyampedu, and Tiruneermalai, have been advised to remain vigilant and seek higher ground as the Adyar River levels are predicted to rise.
In parallel, the WRD has amplified flood warnings for communities along the Kosasthalaiyar River as discharge from the Poondi Reservoir (also known as Sathyamoorthy Sagar) increased from 2,000 to 4,500 cusecs starting Wednesday morning.
The current storage in the Poondi reservoir has reached 2,536 mcft (33.05 feet) against a maximum capacity of 3,231 mcft (35 feet), with inflow from catchment areas and feeder canals, such as Kesavaram Dam and Kandaleru Canal, hitting 2,910 cusecs.
Villages including Nambakkam, Thamaraipakkam, Thirukandalam, Athur, Pandikkavanur, and Jagannathapuram, along with Manali New Town and Sadayankuppam in the Manali zone, are on high alert.
The WRD assured the public that these precautionary releases are made proactively to maintain sufficient buffer capacity in the city's major reservoirs—Chembarambakkam, Puzhal, and Poondi—ensuring that even extensive rainfall will not lead to uncontrolled flooding.
“The public need not panic; all flood regulation protocols are being adhered to,” stated the Chief Engineer of the Chennai Region.
Efforts are being coordinated among the WRD, district administrations, and disaster response teams to guarantee public safety and the ongoing monitoring of river flows.
