Farmers in tail-end coastal taluks of Avudaiyarkovil and Manamelkudi have expressed resentment over the poor availability of water for irrigation, despite irrigation channels in the area receiving copious inflow from water discharged through the Kallanai Kalvai early this month.

Farmers said that though the water had wetted their fields, they were not quite certain about the irrigational prospects, as the discharge has registered a steep decline from the initial 3,500 cusecs.

The entire coastal ayacut of 28,000 hectares cannot be irrigated using the water discharged through the Kallanai Kalvai.

He said that silt accumulation in supply channels had hindered the realisation of waters in the Cauvery Mettur Project villages in the district.

A formula should be arrived at for the discharge of waters through the Kallanai Kalvai and it should be strictly adhered to, the farmers said.
