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.

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.

In a reply in Lok Sabha on Dec. 04, the Ministry of Jal Shakti has revealed that 24 reservoirs in Punjab (14), Himachal Pradesh (9) and Haryana (1) have collectively lost about one fifth of their storage capacity due to sedimentation. Indeed, for years the sedimentation has become a major problem reducing the storage capacity of dams across the country. As a solution the respective governments have mainly relied on desilting which has largely remained limited to plans and in some cases have not achieved the intended purpose. In case of Bhakra the central govt has again mainly focused on desilting as solution.

DRP 011225: Do we know how big is the GLOF threat in the Himalayan states?

The following brilliant report on the threat of GLOFs (Glacial Lake Outburst Floods) is noteworthy from many perspectives. But possibly the most important one is to show the unknown but huge dimensions of the threat. Each of the thousands and thousands of glacial lakes in the Himalayas could pose such a threat. Alarmingly, no one can predict in most of these cases, when this threat will materialize, how big the floods it will bring and what will be the dimensions of the downstream impacts.

While there is no success story of water pollution control in India, where pollution control boards can claim credit for such success, the judiciary also has a significant role in ensuring pollution control in rivers and other water bodies. The state of rivers and other water bodies in India shows how ineffective has been the judiciary in India. Two cases from this week again provides an opportunity to correct this situation: one a suo moto case in the Supreme Court related to Rajasthan Rivers like Jojari, Bandi and Luni and another one in the Delhi High Court related to Yamuna river in the National Capital.

WFD 2025: Impacts of Dams on Inland Fish, Fisherfolks

November 20, 2025November 20, 2025 SANDRPLeave a comment

On the Occasion of World Fisheries Day (WFD) 2025, SANDRP shares the top ten reports underlining the growing impacts of river obstruction projects on freshwater fish species and dependent fisherfolks in India. Indeed, damming free flowing rivers has become the single biggest reason behind growing extinction rate of aquatic life by severely disrupting their migration routes. The iconic hilsa and mahaseer fish in Ganga and Narmada have declined sharply due to construction of Farakka and Sardar Sarovar dams respectively, among others.
