The controversial Malana-I hydroelectric power (HEP) project has again faced significant damages by a ‘cloudburst’ induced flashflood disaster in afternoon of Aug 1, 2025. The 86 Mw project is based on Malana stream, a tributary of Parvati in Kullu district of Himachal Pradesh. Interestingly, the project’s dam site had suffered major destruction exactly one year ago on Aug 1, 2024 in a similar ‘cloudburst’ disaster.

A Glacial Lake Outburst Flood (GLOF) disaster in Lehende Khola river impacted several hydro-electric power (HEP) projects in Nepal on July 8, 2025. The deadly flood occurred around 3 am in Rasuwa and Nuwakot districts of Nepal bordering Tibet region under China control. As a result, the water level in Lehende river rose by 3.5 meters in Timure, Rasuwa. The merging of Kerung and Lehende rivers in Tibet forms the Bhotekoshi river in Nepal and it is part of Trishuli sub-basin under Narayani river system.

A ‘cloudburst’ induced deluge on the intervening night of June 30 and July 01, 2025 has totally destroyed the Patikari Hydroelectric Power (HEP) project in Mandi district of Himachal Pradesh. The 16 Mw project was built in Gudah village on Bakhali khad (Kuklah stream) a tributary of Beas River upstream Pandoh dam. The main project structures including the dam site and powerhouse have been washed away in the disaster. The 12 workers of the project managed to escape in the nick of time.

A massive flash flood following a ‘cloudburst’ has totally damaged the powerhouse and weir site of the Jiwa Small Hydroelectric Project (SHP) in Sainj Valley of Kullu district, Himachal Pradesh on June 25, 2025. The powerhouse of 1 Mw SHP is located in Siund village area near the confluence point of Jiwa nullah with Pin Parbati river. Its weir site is located about 2 km upstream on the Jiwa stream.

In a tragic incident several workers of under construction Indira Priyadarshini Hydel Project are missing after a ‘cloudburst’ induced flash flood struck the project site on June 25, 2025. The 4.8 Mw (2.4 X 2) small hydro power project is being developed by Indira Priyadarshini Hydro Power Pvt Ltd (IPHPPL) on Manuni khad near Sokani Da Kot village under Khaniyara post office of Dharamshala tehsil in Kangra district of Himachal Pradesh. Manuni khad is a tributary of Baner River in Beas basin. The construction work started in Dec 2019 & was scheduled for commissioning in May 2026.

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.

The highest number of such incidents happened in Himachal Pradesh. Incidents are also noteworthy from Sikkim, Arunachal Pradesh and Uttarakhand among the Himalayan states. In addition, noteworthy dam disaster incidents in the year happened in Karnataka, Telangana, Andhra Pradesh and Madhya Pradesh. The previous overview on the issue can be seen by visiting the links 2023, 2022, 2021, 2020.

The sudden gushing water from Adit 2 tunnel of the project near Ralli village flooded the Reckong Peo-Rampur National Highway (NH) 22 with debris in huge amount resulting in closure of highway and causing long traffic jam on both sides. The number of labourers working inside the tunnel is unknown, but reports mention they were recused safely.
