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.

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

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.”

DRP 140725: Dam decommissioning spreads to China

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.

Yamuna Manthan July 2025: Is Delhi Ready for July 2023 like Yamuna Floods?
(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.

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

DRP 30 June 2025: Dam Safety concerns arise as monsoon sets in

The SouthWest Monsoon has just set in and dam safety issues are coming up in large number of dams in Karnataka, Telangana, besides dam disasters in Himachal Pradesh. This shows how much more we need to do to assure structural and operational safety of India’s dams in changing climate.

DRP 16 June 2025: “Indus River older than its landscape, Himalayas”
INDUS RIVER: Stephen Alter, in his article “With the River by My Side” says about Indus River that some rivers are older than the landscape through which they pass: “Nowhere is this clash between hydrological and geological history more apparent than along the Indus, as it passed through Ladakh. This seemingly eternal river has followed its winding course since long before the Himalaya were formed, tossing and tumbling over. Boulders, stones and pebbles that the water polishes and grinds into sand. Eroded flanks of the mountains on either side of the river are scarred and twisted by tectonic forces that lifted giant slabs of rock more than eight kilometres into the clouds but failed to block the persistent flow of the Indus. Driving along the highway that runs parallel to the river, from Leh to Kargil, it feels as if the landscape is a timeless epic that the waters of the Indus have etched in stone.”

Dams, Rivers & People: June 9 2025: The Myths around Brahmaputra River
The Brahmaputra is believed to have two mythological fathers – Lord Brahma and sage Shantanu. In the 16th-century text Yogini Tantra, dedicated to the worship of goddesses like Kali and Kamakhya, the river is linked to an ancient ablution ritual with the following invocation:
O Son of Brahma! O Son of Shantanu! O Lohit! O Son of Lohit!
I bow before you, wash away my sins of the last three births.

HYDRO POWER PROJECTS
Jammu & Kashmir In Kupwara district the 12 Mw Karnah in Kishan Ganga sub basin has joined the long list of HEP projects facing reoccurring damages, repeated delays and cost escalation in Himalayan states. The flash flood, landslides and cloudburst disasters in Feb and May 2025 have further damaged the project and extended its completion date.

DRP NB 260525: Opposition to large hydro as strategic projects

Some of the most prominent reports this week are related to wide spread opposition to large hydro projects in Arunachal Pradesh, Himachal Pradesh, Kerala, among other states. Indeed, there is little sense in building large hydro projects as strategic assets as seems to be the case in Himachal Pradesh and J&K (Chenab basin) and Arunachal Pradesh (Siang basin, among others). Use of security forces to complete pre-feasibility survey when local communities are strongly against the project, as is being done in case of Siang Upper Multipurpose Project is clearly counter-productive in so many ways. In Kerala people have again gathered to oppose the destructive Athirapally Hydro projects that they have been successfully opposing since late 1990s.
