Vijay Opens Mettur Dam for Cauvery Delta Irrigation
Tamil Nadu opened Mettur Dam to send water to farmers in the Cauvery delta.
Chief Minister C. Joseph Vijay opened the gates on Tuesday.
The water will help farmers grow paddy, or rice.
The planned release is expected to last for 45 days.
Rain in Karnataka increased the amount of water flowing into the dam.
Water from Karnataka’s Kabini and Krishnaraja Sagar reservoirs helped raise the inflow.
Officials initially planned to release 3,000 cusecs and may change the amount later.
They will watch the water supply so it can reach farmers throughout the delta.
Tamil Nadu Chief Minister C. Joseph Vijay opened Mettur Dam’s sluice gates on Tuesday for Cauvery delta irrigation.
The release is planned for 45 days and will support paddy cultivation across 12 to 13 delta districts.
Initial discharge was reported as 3,000 cusecs, with officials expected to increase it in phases based on demand and inflows.
Heavy rainfall in Karnataka increased releases from the Kabini and Krishnaraja Sagar reservoirs, raising inflows into Mettur to 10,485 cusecs.
Reports gave differing September 1 storage figures: 91.56 feet in one account and 90.47 feet with 53.70 tmcft available storage in another.
