Following heavy discharge of water from Mettur dam in the Cauvery, the Public Works Department on Saturday resumed discharge of surplus water into the Coleroon river from Mukkombu (Upper Anicut) on Saturday.
It is the second time that water is being released into Coleroon river at Mukkombu within the past three weeks. Water was released into the Coleroon for eight days in the last week of July and first week of August.
According to PWD’s River Conservation Division officials, about 36,000 cusecs of water was realised at Mukkombu Upper Anicut at 5 p.m. on Saturday and of this 30,000 cusecs was released into the Cauvery. About 5,000 cusecs was released into the Coleroon but the quantum is likely to be stepped gradually as the realisation goes up.
Upon receiving inputs that the entire inflow of over one lakh cusecs into the Mettur dam was to be released into the Cauvery, Collector T. Rajamani, who held a meeting with the senior officials, visited the Coleroon river at Kollidam check post in Thiruvanaikoil and reviewed the arrangements being made to ensure safety of people living along the river.
Quoting PWD sources, Mr. Rajamani said that the inflow into the Mettur dam was more than 1.30 lakh cusecs on Saturday evening. The entire inflow was being released into the Cauvery. It was expected to reach Mukkombu Upper Anicut on Sunday. The inflow into the Cauvery from Mukkombu would be maintained around 30,000. Remaining water would be released into the Coleroon.
In order to fill up system tanks and other water bodies in Tiruchi, Thanjavur and Ariyalur districts, water has been released into Uyyakondan, South Bank Canal (SBC), New Kattalai Canal High Level Canal (NKHLC) and Pullampadi canal. While 800 cusecs was released in Uyyakondam, 400 cusecs each was released into SBC, NKHLC and Pullampadi canals.
Out of 75 major tanks in Tiruchi district, Mr. Rajamani said that 35 tanks had already reached their maximum capacity. Remaining 40 tanks would be filled up within two days. About 2 tmc of water could be stored in 75 tanks in the district.
Mr. Rajamani said that there was no need for alarm as there was a well-established water management system in place to prevent flood. The Coleroon had a capacity to carry about 4 lakh cusecs. The PWD, revenue, police, fire and rescue services personnel had been alerted in view of heavy discharge of water.
However, he asked people living along the banks of Cauvery and Coleroon rivers to stay safe and not to cross the rivers.
Nagapattinam Collector S. Suresh Kumar also cautioned people living along the banks of Vennar, Cauvery and Coleroon to move to safer places in view of the heavy water flow anticipated over the next few days.
