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.

DRP 280725: CWC Guidelines on GLOF should have mandated all information in public domain, independent assessment after every GLOF

July 28, 2025July 28, 2025 SANDRPLeave a comment

Guidelines for Structural Measures to Mitigate Adverse Effects of GLOF on Dams Central Water Commission (CWC) on July 23 has issued new guidelines to safeguard dam infrastructure from risks and threat of flash floods triggered by glacial lake outburst floods (GLOFs). The information about this 40 paged documents named Guidelines for Structural Measures to Mitigate Adverse Effects of GLOF on Dams July 2025 was shared by CWC director Shiv Kumar Sharma, in a LinkedIn post. The document is available in PPT format and a pdf link for the same is still not available.

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.

DRP 210725: Moving Joshimath Landslide a threat to Tapovan Vishnugad HEP in UKD?

July 21, 2025July 21, 2025 SANDRP1 Comment

A paper in scientific journal co-authored by Internationally renowned landslide expert Dave Petley (published on June 16 2025 at: https://doi.org/10.1016/j.enggeo.2025.108201) warns that the Joshimath landslide is moving and can threaten the under construction Tapovan Vishnugad hydropower project in Chamoli district in Uttarkhand. The paper says: “The 2023 rapid deformation at Joshimath was preceded by slow movement years ahead. Deforestation in the Joshimath region might have intensified the slope instability. Additional landslide zones were detected in Hailang, Kalpeshwar with similar pattern. Slow-moving landslides have high potential to cause often underestimated damages.”

China decommissions hundreds of dams along Red river China has claimed to have dismantled 300 dams and decommissioned more than 90 percent of small hydropower stations along the Chishui River, also known as the Red River, a key tributary of the upper Yangtze. The move is seen as one of the largest state-led efforts to restore aquatic biodiversity in Asia’s longest river, reversing decades of hydro-infrastructure development that critically endangered native fish species, including the Yangtze sturgeon, the South China Morning Post reported.

Guadalupe River Floods: Understanding the tragedy along ‘The Most Dangerous River valley in the USA’

July 10, 2025July 16, 2025 SANDRPLeave a comment

“This is the most dangerous river valley in the United States, we deal with floods on a regular basis.” – Kerr County judge, Rob Kelly about Guadalupe River[i], 5^th July 2025

“If you live in the Guadalupe River Basin, you also live in one of the three most dangerous regions in the U.S.A. for flash floods!”[ii] – Opening Statement of “Staying safe: A Guide to Flooding in the Guadalupe River Basin[iii]” published by the Guadalupe River basin Authority

Flash Flood Watch Alert from National Weather Service received 3 hrs 21 minutes ahead of the devastating “30 feet high tsunami ball of water[1]”.

“If you do not want to be flooded, do not build or live in a floodplain”– Guadalupe-Blanco River Authority

And yet, several summer camp buildings built on not only floodplains, but on extremely dangerous floodways[iv]. more than 27 children lost to floods.

DRP 070725: Demand for Commission of Inquiry on Hydro Obsession in Himachal

July 7, 2025July 7, 2025 SANDRPLeave a comment

(Feature Image: Flood ravaged Priyadarshini HEP in Manuni khad in Dharamshala, Kangra. Source: Social Media)

Hydropower obsession, Himalayan failure The massive hydropower push, another legacy of post-1990s liberalisation, has amplified vulnerability. Dams have mushroomed across river basins in Kinnaur, Lahaul-Spiti, Chamba, and Kullu — with scant regard for ecological thresholds. Muck from these construction sites is routinely dumped into riverbeds, narrowing channels and raising riverbeds. When the rains arrive, this loose muck turns into a lethal force, taking down everything in its path. The hydropower model — built on the assumption of perpetual revenue — has neither delivered long-term employment nor sustainable energy. Instead, it has left behind ecological scars, displaced communities, and made vast swathes of the state more disaster-prone.

(Feature Image: Dam site of Patikari HEP destroyed by the flash flood.)

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.
