Analyzing a recent paper authored by 37 persons mainly from academics and hydropower related companies on “Sustainable Hydropower”, Eugene Simonov shows why the phrase is an oxymoron, a contradiction in terms. The paper fails to even refer to the most important work on hydropower projects, the report of the World Commission on Dams.

DRP 040825: Arunachal Activists urge Centre to find dimensions of China’s Medog Dam
(Feature Image: Aerial view of the Yarlung Tsangpo’s Great Bend, Medog County)
Arunachal and other Himalayan states activists in a press conference in Delhi have rightly urged the Union Government to publicly demand from China all the features and dimensions of the Medog Dam on Yarlung Tsangpo river, their impact assessments and share the same promptly in public domain before even considering any project like the Siang Upper Multipurpose Project (SUMP). This is important since without knowing the features, dimensions, operating procedures and impact assessments, all the projections being made about the possible impacts of the projects are completely speculative and unfounded.

(Feature Image: Rockslide at dam site of 444 Mw Vishnugad-Pipalkoti HEP on Aug 02, 2025)
At least 12 workers sustained injuries in a rockslide at the under construction Vsihnugad-Pipalkoti Hydro-Electric Power (VPHEP) project in Chamoli district of Uttarakhand. The 444 Mw (111X4) project is being built on Alaknanda River by the Tehri Hydro Development Corporation (THDC).

(Feature Image: Flashflood breached Malana I HEP coffer dam & washed away vehicles on Aug. 01, 2025 in Kullu district, HP)
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.

(Feature Image: Hydrograph of Pin river at Gulling site in Lahul & Spiti on July 04, 2025)
In July 2025 during the South West Monsoon, we have found rivers crossing their respective Highest Flood Levels (HFL) at least at 12 flood monitoring sites of Central Water Commission (CWC). Of the 12 sites, 11 are in Ganga basin and 1 site is in Narmada basin. The details of all these sites are given in table below. The sixth column of the table is the information about rise in meter (m) over the old HFL, duration (hours-hrs) the river has stayed in extreme floods and number of years (yrs) after the HFL is breached. The 12 sites are spread over 5 states: Madhya Pradesh, Uttar Pradesh, Bihar, Uttarakhand and Jharkhand.

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 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.”

(Feature Image: Copco 2 dam removal on the Klamath River, California. Credit: Swiftwater Films, Source: American Rivers)
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.

(Feature Image: EOS-RS Flood Proxy Map: New Delhi, Floods, 12 July 2023,v0.4)
July 13 will mark two years since the Yamuna river stretch in national capital witnessed unprecedented flood spell. The river not just submerged every part of existing available floodplain by several feet but also spilled over to reclaim its lost channels. The unusual flood also breached historic 1978 flood level at Delhi railway bridge by a huge margin, setting new benchmark.

(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.
