Yamuna Mathan 1026: Can Damming Tributaries Revive the River?

October 15, 2026October 15, 2026 SANDRPLeave a comment

(Feature Image: Marking Yamuna Rivers Day on Oct. 7 to commemorate Yamuna crusader Manoj Misra’s 72nd birth anniversary, members of Nadi Mitra Mandli, school students and Home Guard personnel gather in Agra to discuss the importance of the Yamuna’s tributaries and raise awareness about their disappearance.)

The agreement to build the 236-m high Kishau dam on the Tons river raises serious concerns about the future of the Yamuna. Tons is a larger river system in upper basin and plays a vital role in sustaining Yamuna’s ecosystem. Ironically, the ₹15,000-cr project is being promoted in the name of Yamuna rejuvenation and being justified with baseless ‘rain water flowing in waste’ argument. These unconvincing and contradictory claims clearly underline the basic fallacy in the govt’s dam-building approach.

DRP 121026: Will India’s mining ravaged rivers get justice this time?

In a significant development last week, the Supreme Court has expanded its illegal sand mining case from the National Chambal Gharial Sanctuary to rivers across India. For over six months, the apex court has been hearing the matter and issuing directions to state governments of Rajasthan, Madhya Pradesh and Uttar Pradesh. However, the directions issued so far are yet to be fully implemented.

The DRP issue this week seems to have one central theme, connecting the various parts: Deficit monsoon leading to reduced reservoir levels, increased pollution, mass fish deaths and announcements of unprecedented droughts in more than one state. Since it was known to be a super El Nino Year and even IMD had predicted (though ratgher conservatively) deficit monsoon, the ultimate deficit of 12.6% in SW Monsoon rainfall may in fact seem like bit of a relief. This was largely thanks to unexpected above average rainfall in the wettest month of SW Monsoon, July, largely due to favorable Indian Ocean Dipole.

This is the final analysis of CWC’s flood monitoring sites where we could track rivers crossing their respective Highest Flood Levels (HFL) in months of July (at 15 sites), Aug. ( at 10 sites) and Sept. ( at 25 sites) during South West Monsoon Season 2026.

In addition, there are 2 sites where HFL breach has happened on Oct. 01, 2026 and 1 site where HFL breach is missed by narrow margin on Oct. 02, 2026. All the three sites are part of Ganga basin and details of the same is given in table 1 and 2 below.

DRP 280926: Early Warning System important, but not a magic bullet

While writing about the landslide dam breach in Taiwan last year leading to 24 deaths, Dave Petley remarked: As always, the focus should be on vulnerability and resilience rather than only early warning systems (EWS). This is indeed worth emphasizing, underlining, highlighting. While early warning systems can be important and must be used wherever possible, it is not a magic bullet. It is one of the many other instruments in disaster management.

The Sept. 2026 tunnel leakage at NHPC’s Parbati-II HEP in Kullu’s Sainj Valley triggered a sudden flow of water, muck and debris towards Palchara village. Although there was no loss of life, the incident has damaged houses, agricultural land and local infrastructure. It occurred amid a series of leakage and seepage incidents reported in and around the project in recent years, raising renewed concerns over tunnel safety, muck dumping and slope stability in the project area.

The Central Electricity Authority has said in its report that there have been some serious operational and maintenance issues at BBMB’s Pandoh project, part of Beas Sutlej Link Project. In a separate development, Punjab government affidavit in the NGT has said that due to mismanagement at Bhakra-Pong dams, there has been avoidable flood disasters in Punjab in several years. Both developments confirm what we have said about role of BBMB projects in 2023 and 2025 floods in Punjab.

DRP 140926: How prepared are we to face Himalayan Disaster Risks?

The Himalayan disaster risks are increasing in several different ways, including through new types of disasters that are being added now as is evident from the recent Rasuwa floods in Nepal-Tibet, which originated in collapse of hanging glaciers due to melting of permafrost. The frequency, intensity and spread of the risks are also going up. Considering increasing pace of global warming that is inevitable in coming decades, the disaster risks are only going to go up.

Multiple reports over the past month again highlight serious failures in water governance in major cities in the Yamuna basin including Delhi, Gurugram, Greater Noida, Noida, Vrindavan and Bhopal. The problems range from poor rainwater harvesting and inadequate sewage networks to ineffective sewage treatment capacity, unregulated groundwater extraction and neglect of water bodies.
