The Tamil Nadu Water Resources Department is set to repair the damaged apron of the Mukkombu Barrage near Tiruchi. With a sanctioned budget of ₹126 crore, this project aims to secure the irrigation lifeline for 12 lakh acres in the delta region.

  • The State Government has sanctioned ₹126 crore for the Mukkombu Barrage renovation.
  • The apron suffered extensive damage during the 2021 monsoon season.
  • The structure is critical for irrigating approximately 12 lakh acres of farmland.
  • Repairs will prevent riverbed scouring and ensure barrage stability.

The Water Resources Department (WRD) is moving swiftly to address the structural damages at the Mukkombu Barrage (Upper Anicut) located across the Cauvery River near Tiruchi. Following an announcement in the State Assembly, the government has officially sanctioned ₹126 crore to renovate the damaged apron downstream of the barrage shutters.

The degradation of the concrete floor and the displacement of massive boulders on the riverbed have been a major concern for several years. The damage was primarily triggered by the extreme water discharge during the 2021 monsoon, which lasted for over a hundred days. This heavy flow caused significant scouring, leading to large concrete pieces sinking into the riverbed or lying in disarray.

Why This Matters

BozokMedia analysis shows that the apron serves as a critical defense mechanism against hydraulic scouring. Without a stable apron, the force of the flowing water could undermine the foundation of the barrage itself. Given that the Mukkombu Barrage is the nerve center for managing water flow into both the Cauvery and Kollidam rivers, any structural failure could have catastrophic consequences for the entire delta region.

The timely renovation of the apron is non-negotiable to prevent a repeat of the 2018 Kollidam barrage collapse.

Farmers in the region, represented by groups like the Cauvery Delta Farmers Welfare Association, have long urged the government to prioritize this project. The memory of the partial collapse of the Kollidam barrage in 2018 remains a stark reminder of the risks posed by unmaintained hydraulic structures. The Mukkombu barrage is essential for diverting surplus water into the Kollidam to manage river levels effectively.

Historical Background

Commissioned in 1977, the Mukkombu Barrage was engineered to handle a maximum discharge of 1,80,000 cusecs. It remains a cornerstone of the regional economy, providing vital irrigation to nearly 12 lakh acres of agricultural land across the delta.

Did You Know?: The Mukkombu Barrage is often referred to as the 'Upper Anicut,' acting as the primary regulator for the vast Cauvery delta network.
