Dam Induced Flood Disaster

Punjab Floods 2025: Role of Bhakra, Pong and Ranjit Sagar Dams

Every dam can potentially help moderate floods to some extent in the downstream area. This is possible only when the dam is operated with that objective in mind. However, when the dam is NOT operated with that objective and is filled up as soon as there is water available, the same dam can in fact bring avoidable flood disaster in the downstream area.

This is exactly what has happened in Punjab ONCE AGAIN during the 2025 SW Monsoon. This has happened on numerous occasions in the past including in 1978, 1988 and 2023, for example.

No dispute about role of Pong and Bhakra dams in Punjab Aug 2023 floods

Large parts of Punjab are facing flood disaster since about Aug 14, 2023. There is no doubt that these floods are due to sudden, untimely releases of massive quantities of water from BBMB managed Pong and Bhakra Dams. It is welcome news that even Himachal Pradesh Chief Secretary has now listed the three BBMB managed dams situated in HP, namely, Pong, Bhakra and Pandoh among the 21 dams that have violated the Dam Safety Norms and also the CWC Guidelines of 2015 and action will be taken against them.

Over the past 10 days, several Himalayan and North Indian states including national capital Delhi have been battling severe flood disaster which has already taken a heavy toll of human lives apart from displacing people in large numbers and causing massive scale and still unfolding destruction to public-private infrastructure which is still unfolding.

While at macro level the impact of climate change induced excessive and abnormal rainfall patterns is seen as a major culprit but the micro level analysis reveals the deep connection of human activities behind the devastation on ground.

For example, in Himachal and Uttarakhand it is increasingly becoming clear that the large-scale construction and widening of improperly designed and poorly executed highways projects have started proving a double whammy for the fragile hills and river systems.
