Steps should be taken for desilting: farmers’ welfare association
TIRUCHI: The Tiruchi District Cauvery Delta Farmers’ Welfare Association has appealed to the State government to take steps to renovate and modernise all irrigation channels in the delta region by getting financial assistance from the World Bank.
While nearly 13 lakh acres in the delta region were dependant on the Cauvery river for irrigation, on years of abundant monsoon rains up to 2.25 lakh cusecs of water was being discharged into the river from the Krishnaraja Sagar dam by Karnataka. This often results in flooding in Tamil Nadu. If the irrigation channels were renovated, the water could reach the tail-end areas, the president of the association G.Kanagasabai said in a statement here.
Steps should be taken to desilt and clear all impediments on irrigation channels to ensure the smooth flow of water up to the tail end of the delta. Shutters and regulators should be renovated.
The government should also take steps construct seven barrages across the Cauvery river between Upper Anicut (Mukkombu) and the Grand Anicut so as to store the rain water during the monsoon.
He also suggested the construction of four check dams for about 40 feet on a portion of a Coleroon river to prevent the flood discharges overflowing into the villages around Koogur near Tiruchi. The banks of the river should be strengthened and revetment walls should be constructed. He pointed out that several villages were flooded whenever two to three lakh cusecs of surplus water was discharged into the Coleroon. Apart from Koogur, Idayattrumangalam, Anandimedu, Anbil, Ariyur and other villages were affected at times of such heavy discharge in the Coleroon.
