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.

At national level, the NDSA has carried safety audit of 1853 large dams out of 6545 as of Nov. 25, 2025. In July 2025, the Central govt announced to reconstitute NCDS for a period of three years. Before this the NDSA in April 2025 organized a symposium on Dam Safety Act 2021. It has also released the updated version of National Register on Specified Dams 2025. At state level, the Tamil Nadu govt in July 2025 has planned to set up separate dam safety wing. The Punjab govt in May 2025 moved resolution in state assembly to annul Dam Safety Act and planned to enact its own dam safety bill.

India has witnessed several incidents of dam induced floods during south west monsoon 2025. The most remarkable and devastating episode unfolded in Punjab and Himachal Pradesh states in August 2025 largely due to mismanagement of Bhakra, Pong and Ranjit Sagar dams by BBMB. While negligence of BBMB has invited FIRs in Himachal Pradesh, warnings by Punjab govt and petition in NGT, there is no report in public domain suggesting the authority taking any credible action to make its dam operation scientific and accountable after the disaster.

A flash flood disaster caused by a significant breach in Luti dam bund has killed six people while one remained missing in Dhaneshpur village near Vishram Nagar under Balrampur district of Chhattisgarh. Six of the flood victims are members of a single family living about 500 meter downstream from the dam area. About eleven villagers were swept away by strong current of waters. Some of them managed to save their lives by holding on to trees and swimming to their safety. Three persons also suffered injuries in this dam induced flood incident.

DRP 250825: Threat of Dam Floods continue to be ignored

August 25, 2025December 5, 2025 SANDRP2 Comments

(Feature Image: The release of water from Pong Dam has brought devastation to Mand Bhograwan village in Kangra district, where the sudden rise in the Beas river has submerged several acres of fertile land and put houses at risk. Aug 17.)

Sudden release of large quantity of water from the dams has the potential of creating avoidable floods in the downstream areas as we could see last week in case of Ukai Dam water releases affecting Surat in South Gujarat, Ujani and Jayakwadi dam water releases in Maharashtra, Bhakra and Pong dam releases in Punjab and Himachal Pradesh, among others. In all these cases, we can show that earlier water release was warranted based on available information, considering the carrying capacity of the downstream river, but such action was delayed till either the dam was full before water started (e.g. Ujani and Jayakwadi) or too large water releases created avoidable flood impacts in case of Ukai Dam on Tapi River in South Gujarat and also in case of Bhakra and Pong dams. There were also extensive damages in Mirzapur and Chandauli districts of Uttar Pradesh due to sudden release of water from a number of dams including Chandra Prabha Dam, Ahraura dam and Jargo Dam among others.

India has seen several floods brought by breach of embankments during the 2024 monsoon. In Bihar, though the state has received deficit rainfalls, the overspilling of barrages and breaching of several embankments created widescale flood damages. Number of reports have again highlighted the ineffective and adverse role being played by flood protection structures in worsening the deluge impacts. The first part of the overview has covered dam induced flood incidents in the country during 2024 and third part has highlighted incidents of dam induced urban floods.

DRP NB 160924: Urban Flood lessons from Vadodara, Vijaywada

Like every monsoon, a number of cities have faced catastrophic floods in SW monsoon this year. Vadodara and Vijaywada have got the media attention more than any other city for urban floods this year. In both cases a number of factors are common: role of upstream dams, encroachment on water bodies including rivers, lakes, streams, role of illegal sand mining particularly in Vijaywada, not having learnt any lessons from past flood disasters.

It is interesting to see Andhra Pradesh CM hinting at bringing HYDRAA like enforcement institution to remove encroachments on Budameru and other water bodies. Considering the nature of his politics and track record, it is doubtful if this NDA CM will take such a bold step, but it is certainly worthy of consideration for almost all urban areas in India.

DRP NB 090924: Question marks over Yettinahole should not be buried under money spent

The Yettinahole project has seen protests and question marks right from the time when the project was proposed, none of them have been convincingly answered. As the Karnataka Chief Minister and his deputy commissioned a small part of it, those question marks remain as relevant today, including its hydrological viability, environmental impact assessments and sustainability, with hugely weakening of the western ghats by such major interventions without any credible impact assessments. (see: https://sandrp.in/2013/09/18/yettinahole-diversion-an-imprudent-rs-100-billion-proposition/)

It is good to see CWC and MoEF have also raised some questions and asked report even at this stage. One however expects CWC to raise such questions much earlier in the project cycle and before the project becomes fait accomplice. Else, it seems more like politicking. MoEF could have raised issues of violations before the violations happened on ground and should have refused to provide piece meal forest clearances as it has alleged.

DRP NB 190824: Goa River group win important battle against illegal sand mining

This is indeed a rare and important victory by Goa River Sand Protectors’ Network (GRSPN) in their long fight against illegal river sand mining in Goa. Following a petition in the National Green Tribunal the state government has agreed to recall all the environment clearances granted by the State Environment Impact Assessment Authority.

Goa government has agreed since these clearances were given without a District Survey Report (DSR) as required under the sustainable sand mining guidelines of MoEF. While this may sound like a temporary respite based on some technical violation, the fact is most sand mining clearances across India are given without a credible DSR, but it has not been possible to stop such violations elsewhere.
