Synopsis
The Mettur Dam in Tamil Nadu has reached its Full Reservoir Level, prompting a significant increase in water release, which brings hope to local farmers. With heavy rainfall upstream contributing to this milestone, the state prepares for potential flooding in downstream areas. This critical development underscores the dam's importance in irrigating vast agricultural lands.
Key Takeaways
- The Mettur Dam has reached its Full Reservoir Level of 120 feet.
- Water release has increased from 26,000 to 58,000 cusecs.
- Heavy rainfall in Karnataka contributed to the rising water levels.
- Farmers in the delta districts are optimistic about irrigation for crops.
- Authorities are monitoring the situation closely for potential flooding.
Chennai, June 30 (NationPress) The Mettur Dam has achieved its Full Reservoir Level (FRL) of 120 feet, prompting authorities to increase the water discharge from 26,000 to 58,000 cubic feet per second (cusecs).
As per officials from the Water Resources Department (WRD), this marks the first instance this year where the dam has reached its FRL, a significant achievement that offers relief to farmers and communities reliant on water across Tamil Nadu.
Out of the total discharge, approximately 22,500 cusecs is being released via the dam’s main powerhouse and tunnel powerhouse. An additional 2,600 cusecs is flowing through the High-Level Sluice (HLS), while the remaining water is released through the Ellis Saddle surplus channel.
This increase in the dam’s water level follows several weeks of consistent inflows from the Cauvery catchment areas in Karnataka, which have experienced heavy rainfall since early June.
“The ongoing rainfall in the upstream regions of the Cauvery basin in Karnataka has led to a significant rise in inflows into Mettur. This has enabled the reservoir to reach its maximum capacity of approximately 93.4 TMC feet,” stated a senior WRD official.
Farmers in the delta districts, who rely on Mettur water for irrigation of paddy and other crops, have expressed their gratitude for this development. “This is a tremendous relief for us. The water will enable us to engage in Kuruvai cultivation with assurance,” said S. Marimuthu, a farmer from Thanjavur district.
Constructed in 1934, the dam is one of the oldest and largest in Tamil Nadu, serving as the primary irrigation source for over 12 lakh acres in the Cauvery delta.
Officials have cautioned residents living along the riverbanks downstream of Mettur to stay alert, as the increased discharge may elevate water levels in the Cauvery and its tributaries.
“We are closely observing the situation. The release is essential to keep the dam at safe levels given the heavy inflows,” the official added.
The state government has also notified district administrations in Salem, Erode, Tiruchirapalli, and downstream areas to prepare for potential flooding in low-lying regions.
With the monsoon anticipated to remain active over the Cauvery basin in the upcoming days, authorities will continue to adjust the water release from the dam based on inflow trends and safety considerations.
Point of View
It's essential to spotlight the significance of the Mettur Dam's current status. This development not only affects local agriculture but also highlights the ongoing challenges posed by climate variability. The government's proactive measures to manage water levels and prepare for flooding exemplify a commitment to safeguarding communities. Monitoring these changes reflects our responsibility as a nation to address environmental concerns and support our farmers.
