Nearly one lakh cubic feet per second (cusecs) of water was diverted into the Kollidam from Upper Anicut (Mukkombu) near Tiruchi on Thursday in the wake of heavy discharge of water into the Cauvery from Karnataka and Mettur.
The realisation at Upper Anicut was 1.33 lakh cusecs around 4 p.m. on Thursday. Of this, 98,120 cusecs was diverted into the Kollidam and the rest flowed in the Cauvery, downstream the Mukkombu barrage. The realisation is set to rise as the discharge from Mettur rose up to over 1.65 lakh cusecs on Thursday evening.
Flood warnings have been issued for people living along the Kollidam in Tiruchi, Ariyalur, and other delta districts. Most bathing ghats on the Cauvery in Tiruchi, including the one at Amma Mandapam, were barricaded by the police as a precautionary measure.
The heavy discharge triggered some anxious moments for the Water Resources Department as the Kollidam river bund suffered erosions at a couple of vulnerable places – near Kariyamanickam and Keezha Anbil in Tiruchi district. Acting swiftly, the officials started reinforcing the bunds with stone boulders. According to sources, the reinforcement work was completed at Keezha Anbil and was continuing at Kariyamanickam by evening on Thursday.
Vertical slips were reported on the river bund at both the places in 2022 when there was heavy discharge in the Kollidam. The WRD had detected the erosions in time then and reinforced the bund with stone boulders. According to sources, the river bund had suffered some erosion close to the same spot. The WRD proposal to execute a flood-mitigation project at an estimate of ₹12 crore is pending approval.
Kollidam bridge closed
The heavy discharge left a high tension power transmission tower tilting dangerously near the new Kollidam bridge in the city on Thursday morning, forcing the police to close the bridge for traffic for some hours as a precautionary measure.
