This annual overview complies the remaining relevant reports from 2024 concerning safety of dam structures in India. As per a report, the incident of damage to Tungabhadra dam gate in August 2024, raised alarm for other aging dams in Karnataka. In fact, the Bhadra dam also witnessed jamming of a gate due to rust in June 2024. Similarly, the Kabini reservoir has been dealing with a leakage for the past three years. The report further highlights negligence in dams’ monitoring and inadequate expertise and corruption often impacting the quality of maintenance works of dams in the state. As per another report taking sou moto action, the Karnataka High Court in January 2024, banned mining and blasting activities within a 20 km radius of the Krishna Raja Sagara dam in the state.

Besides the dam induced flood events, the available media reports show two incidents of breach in industrial dams causing substantial flood damages to local people in India during 2024. The first incident took place in NMDC’s iron ore mine in Kirandul area of Dantewada district in Chhattisgarh in July 2024 in which collapse of an iron ore waste ‘check dam’ resulted in extensive flood damages in downstream areas.

The second such incident happened in September 2024 when aluminium mine waste dyke breached in Vedanta Alumina Lanjigarh facility in Kalahandi district of Odisha flooding scores of farmlands with toxic mud. Interestingly both the NMDC and Vedanta have blamed extreme rains reason behind the breach in their mine waste collection facilities while the reports indicate negligence in maintenance of these dams.

This 2024 annual overview focusses on important reports highlighting the safety and sustainability issues of the hydro and dam projects in India in 2024 in the context of Climate Change, including Glacier melt and GLOFs. The compilation shows that the climate change driven extreme weather events have become significant threat for the structural safety of these projects.

This is even more relevant in inherently vulnerable areas like the Himalayas and Western Ghats from the point of view of seismic activity, young erosion prone mountain, flash floods, avalanches and landslides. Here the impact of climate change effects like more intensified hydrological cycles, cloud bursts, reduction in snow fall, glacier melts and GLOF (Glacier Lake Outburst Flood) increase the vulnerability including landslide dams and avalanche dams.

This annual overview focusses on the functioning of National Dam Safety Authority (NDSA) and related institutions in 2024 to understand if the functioning of these institutions have made Indian Dams any safer? Here functioning of Central Water Commission (CWC) is also important as CWC people head all the dam safety panels. The dam safety related institutions were formed following the passage of Dam Safety Act 2021 and hence there were promises and hopes that these institutions will make our dams safer.

जल शक्ति मंत्रालय की संसदीय समिति ने मार्च 2023 की 20वीं रिपोर्ट [i] में जल संसाधन, नदी विकास और गंगा संरक्षण विभाग से भारत में बांधों और सम्बंधित परियोजनाओं के व्यावहारिक जीवनकाल और प्रदर्शन का आकलन करने की व्यवस्था को लेकर सवाल किया था। वास्तव में इस सवाल का बांधों को हटाने के विचार पर सीधा असर पड़ता। लेकिन विभाग ने जवाब दिया था कि “बांधों के व्यावहारिक जीवनकाल और प्रदर्शन का आकलन करने के लिए कोई तंत्र नहीं है। और, बांध मालिकों की ओर से किसी भी बांध को हटाने के लिए कोई जानकारी/सिफारिश प्रस्तुत नहीं की गई है।”
