Abundant storage in Thirumoorthy Dam raises hopes among farmers for water adequacy in tail-end areas of PAP Main Canal
At a recent meeting to discuss the issue, the farmers arrived at a decision to stage prolonged protests if the Water Resource Department fails to channel water to a height of 4.8 feet (from the existing 4.5 feet) at the zero point of Vellakovil branch canal.
Out of 2300 mcft (million cubic feet) drawn from the dam for supply through PAP main canal, the water distribution for Vellakoil branch should be one-eighth. Even if 20% of water transmission loss is factored in, the realisation has to be not less than 230 mcft at the zero point. 'But, the water realisation is only 170 mcft. This is not sufficient. At some locations in tail-end areas, water flow does not last even for two days. There is severe shortage of water for livestock, drinking purpose and irrigation,' P. Velusamy, president of PAP Vellakoil Branch Canal Water Conservation Movement said.
The farmers hope the Water Resources Department will deploy better water management methods this time around with abundant water in the Thirumoorthy Dam.
Against the full depth of 60 feet, the level in the dam rose up to 53.92 ft on Wednesday. The storage was 1483 mcft against capacity of 1744. Against inflow of 252 cusecs, discharge of 1160 cusecs was maintained. At the same day last year, the level was 31.1 feet and storage was 680 mcft.
Also, the usable storage of the system dams of Parambikulam Aliyar Project was estimated at 7269.92 mcft by the Water Resources Department, on Wednesday.
Official sources said the State Government has been promised funds by the Union Ministry of Jal Sakthi under Dam Rehabilitation and Improvement Project (DRIP). Phase II and III, co-financed by the World Bank and the Asian Infrastructure and Investment Bank. Thirumoorthy Dam figures among 145 out of 736 dams proposed in the two phases that are more than 60 years old.

A.P. CM calls for urgent flood precautions in view of heavy rain
Andhra Pradesh Chief Minister N. Chandrababu Naidu on Wednesday reviewed the heavy rainfall situation in the State at a meeting with Ministers and senior officials, calling for urgent flood precautions, efficient use of incoming water resources and round-the-clock monitoring of the situation to safeguard lives and property. 'We must stay ahead of the situation and protect lives,' Mr. Naidu emphasised at the meeting. In a key directive, Mr. Naidu ordered that up to 4 tmc ft of incoming floodwaters be diverted daily to fill Somasila and Kandaleru reservoirs, rather than allowing the water to flow into the sea. The officials reported significant inflows from the upper catchments such as Mylavaram into Budameru and Velagaleru streams, which are being discharged into the Krishna River. ₹40 crore for Budameru–Velagaleru utility tunnel Mr. Naidu sanctioned ₹40 crore for the Budameru–Velagaleru utility tunnel and instructed that the Budameru Diversion Channel be completed on a war-footing. With meteorological officials forecasting continued heavy rainfall in the coming days, the Chief Minister instructed officials to monitor flash flood situations in the streams and tributaries of the Krishna and issue timely alerts to the downstream villages and low-lying areas. According to the Water Resources Department, the inflows into the Krishna may touch 5 lakh cusecs by Thursday. Currently, 3.09 lakh cusecs are being released through 35 gates of the Prakasam Barrage, with an additional 5,000 cusecs being diverted into canals. The gates at the upstream Nagarjunasagar and Pulichintala dams have also been lifted. Mr. Naidu asked the respective district administrations to prepare for carrying out evacuations in the vulnerable areas and clear stagnant water from roads and drains. Meanwhile, floodwaters from Kondaveeti Vagu and Paala Vagu are being pumped into the Krishna. Mr. Naidu ordered immediate removal of silt and water hyacinth from the canals to ensure smooth water flow and reinforcement of the embankments of canals and tanks to prevent breaches. Calling the rains an opportunity for groundwater recharge, the Chief Minister asked the panchayati raj and forest departments to identify suitable trenching locations and take up digging works under the MGNREGS to maximise rural water retention. With reservoirs and rivers brimming, Mr. Naidu asked the officials to stay alert, maintain direct communication with farmers, and provide real-time updates to the people. Home Minister V. Anitha, Water Resources Department Minister Nimmala Ramanaidu, Chief Secretary K.S. Vijayanand, and the officials of the disaster management, agriculture, and water resources departments attended the meeting.

T.N. Chief Secretary inspects flood mitigation projects at Pallikaranai
Tamil Nadu Chief Secretary N. Muruganandam inspected flood mitigation projects executed by the Water Resources Department (WRD) near the Pallikaranai marshland on Saturday (August 9, 2025), and instructed officials to expedite the work to minimise inundation before the onset of the Northeast monsoon. He inspected the ₹91-crore work to construct a 1.2-km-long channel that aimed at mitigating waterlogging in areas like Velachery's Vijaya Nagar and Ram Nagar, Semmencheri, and Perumbakkam, around the marshland. It would carry a portion of the floodwater from south Buckingham canal near Okkiam maduvu to the sea. According to the WRD, the channel, which would have the capacity to carry about 1,000 cubic feet per second of water, would reduce the burden on Okkiam Maduvu and Buckingham canal. The channel would travel along localities like Uthandi before draining into the sea. The project has been designed to handle the backflow of seawater due to tidal action. Mr. Muruganandam also reviewed the progress of the Greater Chennai Corporation's (GCC) project to restore Ramanthangal lake in Sholinganallur. The project is being implemented at a cost of ₹1.26 crore under the 'Namakku Namme' scheme. Senior officials from the WRD, GCC, and Chennai Metrowater were also present.
