There have been at least three incidents of leakages from fly ash dykes at Reliance’s Sasan UMPP in MP & NTPC’s Unchahar Plant in Raebareli, UP in Aug. 2026. All the three incidents have considerably affected nearby village and farmer communities in both the states. Notably, both projects have also experienced ash dyke related leakages and failures in the recent past, raising serious concerns over safety of the structures and safe disposal of the toxic fly ash.

Himalayan Floods Are Not Just a Water Event, They Are a Debris Event

September 3, 2026September 4, 2026 SANDRPLeave a comment

As I write this, over 1,200 people are dead across Nepal and China, and nearly 5500 more are missing. About 900 people are trapped in hydropower tunnels clogged by debris. Herculean national and international efforts are being made to bring them out, but the tunnel entrances are sealed by dense plugs of compressed sediment, and rescuers have no idea of the extent of that blockage. An Australian tunnel expert summed up, “we might only have to dig 10 meters, or we might have to dig 100 meters.” [1]

One More Monsoon: Governance, Accountability and the Collapse of Madhopur Barrage

June 21, 2026June 23, 2026 SANDRPLeave a comment

“Ye paani samne aa gaya. Gate khul nahi rahe to grenade dalo, blast kardo. Ye pura beh jaayega.”

“The water is right in front of us. If the gates are not opening, blast them with a grenade. Everything will be washed off.”

– Ex-Minister Lal Singh Chaudhary (Basholi, J&K) at Madhopur Barrage, on the eve of Madhopur gate collapse.[1]

On the 27^th of August 2025, after facing several days of floods from a swollen, angry Ravi River, three gates of Madhopur Barrage at Pathankot crashed into the brown, swirling waters. Around this time, a team of engineers and helpers were on the barrage, making dangerous but futile attempts at opening the jammed gates. Three people fell in the flood, two were rescued but one body was later recovered underwater, from the wrecked gates they were trying to open. Earlier that morning, 22 CRPF jawans were airlifted from a building next to the barrage, moments before it collapsed into the raging river. The flood unleashed a wave of destruction in the downstream.

Ravi ka Kinara Kaisa hai? River Ravi through its people

March 28, 2026March 28, 2026 SANDRP1 Comment

Flowing under many names: Vedic Parushni, Puranic Iravati, Greek Hydraotes, River Ravi is arguably the most storied of the five rivers meeting the Indus.

Ravi’s flow from the glacial heights of Himalayas to the fertile plains of Punjab has been embellished in songs and stories for centuries. Heth Vage Ravi Dariya or “Below flows the River Ravi” is a ubiquitous phrase in songs and poems.[1] On the banks of Ranjit Sagar Dam on Ravi, Manbhavan Singh Kahlon, himself a poet-activist muses, “We Punjabis have always written poetry around our rivers. Perhaps even too much, I sometimes think. But most of Ravi’s poetry has been left back in Pakistan.” Pakistan, on the other hand, thinks most of Ravi’s water has been left back in India.

Amid concerns over safety and construction quality, the Polavaram project work has moved during 2025 to achieve Dec. 2027 completion target. However, not much progress has been made regarding the backwater study and addressing the issues of affected tribals and areas in Telangana, Odisha and Chhattisgarh. Meanwhile, after failing to push PBLP (Polavaram Banakacherla Link Project), the Andhra govt has proposed another contentious PNLP to divert Godavari River waters. The Stop Work order issued by the MoEF in 2011 remains suspended for all these years, making a mockery of the MoEF regulations. Wrapping up the available information, this overview shares the year-round updates on safety, progress, backwater study and linking plans related to the controversial Polavaram dam project in 2025. Our previous overview on the project can be seen here.

The Day Salun Village Fell: Impacts of Cascading Hydropower Projects in the Ravi Basin

December 8, 2025December 8, 2025 SANDRPLeave a comment

Salun village, perched roughly 50 feet above the Ravi River, had its moment of fame on the 26th August 2025 — a moment that also became its last. On the dark, rainy afternoon, the small village with homes, rajma fields, apple orchards and cattle sheds collapsed into the flooded River Ravi like a house of cards. In a matter of 30 minutes, ancestral homes with warm hearths, blankets for the coming winter, old report cards and wedding albums, adhar cards and bankbooks-entire archives of living-were erased. Villagers, who managed to escape in time stood in awe and saw their village going extinct before their eyes.

In 2025, we could find reports on two Indian cities facing the impact of dam induced floods. While the excessive discharges by Himayat Sagar reservoir severely inundated residential areas along Musi river in Hyderabad in last week of Sept 2025, the significant releases by Ukai dam authority into Tapi river affected daily life in Surat city twice in mid Aug and first week of Sept. 2025.
