As the year 2025 ends, reflecting on the DRP related developments over the year and even in this last DRP of 2025, one cannot but see largely pessimistic situation for India’s Rivers, Water Bodies, Hills and Mountains, Floodplains, and for the environment in general. As we saw during South West Monsoon 2025, the flood disasters have been so severe that the number of deaths in South Ais are the highest among all climate disasters of 2025 according to the just released Christian Aid report. The spread, intensity and frequency of the disasters are only going to increase, but we, including the government and the society seems to show little sincerity in dealing with this.

DRP 221225: Is it so difficult to understand the importance of Aravalli Mountains?

Why is it so difficult, for the Union Govt, MoEF, its experts, but most shockingly, for the Supreme Court to understand the importance of Aravalli Mountains – India’s most ancient and ecologically sensitive range? What exactly is driving the unacceptable decision of the apex court? According to the Forest Survey of India, applying the new definition would result in only around 8.7% of the mapped Aravalli landforms being eligible for protection, leaving a substantial portion unregulated.

2025 has seen increase in concerns and protests against pump storage projects (PSP) across the country. While citizens and experts have criticized Sharavathi PSP in Karnataka, Sillahalla PSP in Tamil Nadu, Shahbad PSP in Rajasthan, Bargi PSP in Madhya pradesh and numerous PSPs in western ghats in Maharashtra for their potential adverse impacts on forest, environment, endangered animals, the Sileru, Pedikota and Yerravaram PSPs in Andhra Pradesh faced resistance for undermining tribal and forest rights. Indeed, most of the PSPs are being proposed in sensitive region of Western Ghats and tribal dominated population endangering both the wildlife and vulnerable population.

In May 2025, Sikkim Vigilance Police conducted raid in several cities to probe allegations of financial corruption and fraud in 1200 Mw Teesta III HEP dam project claiming that the material gathered could unearth massive scandal that compromised the dam’s safety and led to its structural failure in Oct. 2023. The Assam GST department in Sept. 2025 has uncovered ₹8.2 cr irregularities in tax filings and transactions by the company involved in constructing the dam of 2000 Mw Subansiri Lower HEP.

2025: Silt accumulation in Indian Dams: Reducing entry of silt is the only viable option

This annual overview highlights the critical issue of siltation in dams across India. Silt accumulation is defeating the very ‘multi-purposes’ for which they were built. While the reduced storage has been hampering dam-based water supplies, it is also leading to their fast filling up and untimely releases in monsoon season thus creating avoidable floods. It is in some case has also been resulting in plans to construct additional reservoirs and increase in dam height.

The year 2025 has seen revealing information on three inquiry reports highlighting how the Kalewshwaram project have become a massive failure on all fronts be it designing or implementing the dam project or even acting on probe reports. While govt seems to reverify liability of officials indicted in V&E report, it ended up seeking CBI investigation after tabling Ghose panel report in state assembly in Aug 2025. Similarly, the NDSA report is being followed only for fixing the damages while action against the responsible govt officials and private players is clearly missing.

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.

DRP 151225: Hydro Projects continue to provide troubling news

There are troubling news reports about a number of hydropower projects, even as the hydro industry tries its best to present a positive picture. NHPC tries to say that one of its 250 MW units at the Subansiri Lower HEP is good news. However, the fact that WII’s several years old recommendation that project should not be used for peaking power generation till studies about its impact on elephant corridor are complete. But the WII recommendation presented at the National Wildlife Board over 22 months ago is yet to be implemented. The serious financial trouble that the project is in, is also apparent from its desperate attempt to use the forest land as collateral, rejected by MoEF. The closing down of the NHPC office for the Subansisi Upper HEP in Upper Subansiri district came following agitation by the students Union and others there opposing the project.

The SLCB tunnel collapse in Feb. 2025 is among worst dam-tunnel disaster this year in India. The incident occurred just four days after resuming tunneling work after a long halt killing at least 8 workers. Despite, two-month long multi agency search operation only two bodies were retrieved while mortals of six still remain buried inside the tunnel. The TBM involved in tunnelling has also been damaged. Given risky situation the rescue work was stopped in April end and there is no update on the same so far. Nearly 10 months after the disaster, there is no official report probing the reasons and addressing the concerns over inadequate geological, geotechnical inspections.

Hidden Faults, Flowing Rivers: How Tectonics Shape Central India’s Upper Ken Basin

Central India’s Upper Ken Basin, where the ancient Bundelkhand Craton meets the younger Vindhyan sedimentary rocks, appears at first glance to be a quiet and time-worn landscape. But new research reveals that the region is still being shaped by deep, hidden tectonic forces. In a recent study, geographers Kundan Parmar and Satheesh Chothodi used high-resolution elevation data and underground gravity measurements to decode the subtle fingerprints of active deformation imprinted onto the basin’s rivers and valleys. Their findings show that ancient faults, modern uplift and slow tilting continue to steer the paths of the Ken, Sonar and Bearma Rivers (all part of Ken Basin), creating steep drops, shifting channels and asymmetric basins.
