On 25 June 2026, the chief ministers of Karnataka (D.K. Shivakumar), Telangana (A. Revanth Reddy) and Andhra Pradesh (N. Chandrababu Naidu) joined Union Jal Shakti Minister C.R. Patil to commission 33 new spillway gates at the Tungabhadra Dam. The event highlighted renewed inter‑state cooperation, but also exposed lingering disputes over upstream projects and dam safety.
Key Developments
- Installation of high‑grade steel spillway gates costing ₹51 crore, expected to serve for 60 years.
- Chief ministers pledged stronger inter‑state water‑sharing cooperation.
- Union Minister assured a national programme to remove siltation from reservoirs, including Tungabhadra.
- Discussion on the Upper Bhadra Project, which remains a point of contention.
Important Facts
- The dam irrigates 16.4 lakh acres: 9.26 lakh in Karnataka, 6.25 lakh in Andhra Pradesh and 87,000 in Telangana.
- During August 2024, a crest gate was washed away when the reservoir was full at 105 tmc ft (thousand million cubic feet).
- Original storage capacity was 133 tmc ft; siltation has reduced it to about 106 tmc ft.
- The Centre had earmarked ₹5,300 crore for the Upper Bhadra scheme in the 2023‑24 budget, but later omitted it from central schemes, leaving implementation to a Karnataka undertaking.
Exam Relevance
Water‑resource management is a recurring topic in GS‑2 (Polity) and GS‑3 (Environment/Economy). The article illustrates federal coordination, the role of the Jal Shakti Ministry, and the challenges of inter‑state river disputes. Understanding concepts like inter‑state water sharing and siltation is essential for answering questions on river basin management, disaster mitigation, and sustainable development.
Way Forward
To safeguard dam safety, the Centre should fast‑track silt‑removal operations across the country and monitor rehabilitation projects in all 19 states where major dams exist. A transparent, legally binding water‑sharing formula for the Tungabhadra basin can pre‑empt future disputes. Moreover, the Upper Bhadra scheme needs a joint‑state review to balance Karnataka’s irrigation aspirations with the downstream states’ water security. Emphasising preventive maintenance over reactive repairs will reduce economic loss and protect lives.
