The Tungabhadra reservoir, a shared lifeline for irrigation and drinking water across Andhra Pradesh, Telangana and Karnataka, is set to reopen with a rebuilt set of crest gates on June 25, in a joint inauguration by the chief ministers of all three states. Andhra Pradesh's N. Chandrababu Naidu, Telangana's A. Revanth Reddy and Karnataka's D.K. Shivakumar are expected to attend together, an unusual show of coordination for a reservoir that has long been a source of interstate friction over water sharing.
The rebuild was forced by a crisis in August 2024, when one of the dam's crest gates snapped off its chain and was swept away during peak monsoon storage, sending a sudden, uncontrolled surge of water downstream. The failure raised alarm across nine districts spanning the three states, both for the immediate flood risk and for what it signalled about the ageing condition of a structure that dates back decades. Authorities scrambled at the time to stabilise the breach and assess the remaining 32 gates before the next storage cycle.
In the months since, all 33 crest gates have been replaced at a cost of roughly Rs 51 crore, engineered to remain functional for an estimated 55 to 60 years. The scale of the replacement, redoing every gate rather than patching the one that failed, reflects how seriously the three states treated the 2024 incident as a warning about the dam's broader structural fatigue rather than an isolated mechanical fault.
Beyond the ribbon-cutting, the June 25 event is expected to double as a venue for talks between the three states on water-sharing arrangements and interstate irrigation planning, an issue that resurfaces every time the reservoir's storage or safety comes into question. Officials are also likely to discuss the proposed Navali parallel reservoir, an idea floated as a long-term hedge against the kind of storage loss the region faced when the gate failed in 2024.
For farmers and towns downstream in all three states, the rebuilt gates restore a measure of confidence in a structure they depend on every monsoon. Whether the accompanying water-sharing talks produce anything more durable than past rounds of discussion remains the open question hanging over an otherwise straightforward infrastructure milestone.
