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.

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.

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.”

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

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.

Dabhil Mauli: Stories and Struggles of a Small River in the Western Ghats

June 23, 2025June 24, 2025 SANDRPLeave a comment

At the window of his new house, in a crowded suburb of Pune sits Aba Gawas. He looks out at the traffic and talks of his river Dabhil, more than 400 kms away from him. For years, Aba has fought hard to protect the river. He calls it Dabhil Mauli, a term of endearment reserved for mothers and deities. He is not keeping very well and longs to return to Dabhil Mauli. I realize with a sudden pang, rivers are home.
