The Impasse Over Water Limits

Kerala Water Resources Minister Mons Joseph reaffirmed the state's unwavering opposition to any increase in the Mullaperiyar dam's water level during a press briefing in Kottayam on Thursday. The statement follows the Tamil Nadu government's recent budget announcement declaring its intent to pursue water levels beyond the current 142-foot cap. Kerala officials maintain that neither state possesses the authority to unilaterally adjust these limits, which were established through Supreme Court proceedings to balance regional interests.

Safety Directives Unfulfilled

Minister Joseph highlighted a significant lack of compliance regarding safety protocols mandated by the apex court. According to the Minister, Tamil Nadu has failed to conduct necessary inspections or implement strengthening measures for the secondary 'baby dam.' Kerala has formally requested that the National Dam Safety Authority lead a comprehensive safety audit, an action originally slated for completion by December 31. The Minister noted that even basic safety reviews remain pending despite the age of the structure, which is now 131 years old.

Key Facts

  • Kerala demands the construction of a new dam to ensure the safety of downstream residents while maintaining water supply to Tamil Nadu.
  • Minister Joseph criticized the lack of tangible progress over the last decade, stating that previous diplomatic efforts failed to produce significant decisions.
  • The state has appointed Ashutosh Das of Odisha as its representative on the Mullaperiyar Expert Committee to ensure a rigorous technical defense of Kerala's position.
  • An emergency meeting convened by Chief Minister V.D. Satheesan recently reviewed the implications of Tamil Nadu's budget proposal.

Flood Management and Infrastructure

Addressing immediate regional concerns, the Minister reported that floodwaters in Kottayam and Upper Kuttanad are beginning to recede. While accumulated debris at the Thottappally spillway in Alappuzha initially hindered drainage, Joseph confirmed that remedial actions have restored the flow of water into the sea. The state government remains focused on ensuring the operational integrity of water discharge systems during the current period of heightened environmental concern.

What Happens Next

The Kerala government is preparing to escalate the matter to the Supreme Court if Tamil Nadu proceeds with its plan to raise the reservoir level. The state intends to lobby the Union Ministry of Jal Shakti and the Central government to prioritize the safety audit by the National Dam Safety Authority. Negotiations will likely focus on finding a consensus that preserves the security of Kerala's citizens without disrupting the water requirements of Tamil Nadu.
