- Official release of irrigation water from Grand Anicut (Kallanai) completed.
- Expected coverage of over 4.8 lakh hectares for Samba and Thaladi paddy.
- Key districts including Thanjavur and Tiruvarur to benefit significantly.
In a significant move for the agricultural heartland of Tamil Nadu, Agriculture Minister R. Vinoth and Minorities Welfare Minister A.M. Shahjahan officially released irrigation water from the historic Grand Anicut (Kallanai) near Thanjavur on Sunday. The ceremony was marked by tradition, as ministers, district collectors, and local farmers offered paddy grains and flowers to the Cauvery river to mark the commencement of the sowing season.
The release is vital for the Samba and Thaladi paddy seasons, which are the primary cultivation cycles for the delta districts, including Thanjavur, Tiruvarur, Mayiladuthurai, Nagapattinam, and Karaikal. As the regulators were opened, water flowed into the Cauvery, Vennaru, and Kollidam rivers. Officials confirmed the release of 1,000 cusecs each into the Cauvery and Vennaru, and 500 cusecs into the Grand Anicut canal and Kollidam.
Why This Matters
BozokMedia analysis shows that the timely release of water is the single most critical factor for the socio-economic stability of the Cauvery delta. After facing delays due to low storage levels at the Mettur dam, this release provides the necessary momentum for farmers to begin their intensive cultivation cycles, ensuring regional food security.
The successful management of water flow from Mettur to the Grand Anicut is the cornerstone of the delta's agricultural prosperity.
This year's irrigation cycle faced hurdles as the Mettur dam was not opened on its scheduled date of June 12 due to poor water storage. It was only after the water level crossed the 90-foot mark that Chief Minister C. Joseph Vijay authorized the release on September 1. Following a five-day journey through the river course, the water reached the Grand Anicut on Saturday night.
Projected Paddy Coverage by District
| District | Expected Paddy Coverage |
|---|---|
| Thanjavur | 1.25 lakh acres |
| Tiruvarur | 1.40 lakh hectares |
| Nagapattinam | 61,000 hectares |
| Mayiladuthurai | 64,000 acres |
Historical Background: The Grand Anicut, or Kallanai, is an architectural marvel dating back nearly two millennia, constructed during the Chola dynasty. It remains one of the oldest water-regulation structures in the world, continuing to serve as the lifeline for South Indian agriculture.
