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.

In the third month of the 2026 southwest monsoon season, we have been able to document rivers breaching their respective Highest Flood Levels (HFLs) at least at 10 Central Water Commission (CWC) flood monitoring sites. These sites are spread across five river basins and four states mainly in central and east India.

यमुना: दिल्ली में बाढ़ का बढ़ता खतरा और नदी बाढ़ क्षेत्र प्रबंधन

August 27, 2026 SANDRPLeave a comment

इसमें कोई संदेह नहीं है कि दिल्ली में यमुना के बाढ़ क्षेत्र (खादर) में बढ़ते अतिक्रमण ने प्राकृतिक बाढ़ को आपदा में बदलने का खतरा पैदा कर दिया है। खादर क्षेत्र का सीमांगन नहीं होने के कारण ओ-ज़ोन (यमुना खादर) का सही तरह से क्रियान्वयन नहीं हो रहा है।

लेकिन वर्तमान बहस समस्या के केवल एक हिस्से तक सीमित है, जबकि इसके मूल कारणों पर पर्याप्त ध्यान नहीं दिया जा रहा। सबसे पहले यह समझना जरूरी है कि यमुना के खादर पर किस प्रकार के अतिक्रमण हुए हैं और इसकी सुरक्षा के लिए कौन-सा कानूनी एवं संस्थागत ढांचा उपलब्ध है।

Yamuna Manthan Aug 2026: Floodplains remain under threat

Three recent studies have once again highlighted both the severe degradation of the Yamuna and the critical role of its floodplain in Delhi. Their findings make it clear that cleaning sewage alone will not revive the river. Protecting natural flows, restoring floodplain connectivity and conserving wetlands are equally important for reducing flood risk, recharging groundwater and sustaining the river’s ecology. Undoubtedly, the Yamuna floodplain has already suffered extensive encroachment, fragmentation and ecological damage due to weak governance.

July 2026: Flood Threat from Landslide Lake in Sainj Valley, Himachal Pradesh

August 1, 2026 SANDRPLeave a comment

(Feature Image: Google Earth image marks locations mentioned in the report along landslide lakes and nearby hydropower infrastructure in the Sainj Valley. The red circle marks the probable location of the landslide lake on Jiva nullah, while the yellow circle indicates the landslide lake that formed on Varshanu nullah in June 2025. The numbered locations represent: (1) 1 MW Jiva Small HEP, (2) 100 MW Sainj HEP powerhouse, (3) 800 MW Parbati-II HEP powerhouse and (4) the dam of the 520 MW Parbati-III HEP.)

Fresh landslides and the continued expansion of a landslide-dammed lake on Jiva nullah in the Sainj Valley of Kullu district, Himachal Pradesh, have once again raised concerns over a potential downstream flood disaster. Although no official estimate of the lake’s area or stored water volume has been made public, local residents say the impounded water body has expanded steadily over the past three years.

A flash flood in the Chanju stream on July 19, 2026, caused significant damage to the Chanju-III Hydroelectric Project (HEP) in Ravi basin. The project is being built near Chanju and Dehra villages in Churah subdivision of Chamba district, Himachal Pradesh. As per initial reports, the swollen stream washed away large quantities of construction material and damaged several temporary structures at the project site.

The cofferdam of Ratle Hydroelectric Project (HEP) was partially damaged due to a floods in Chenab river on July 23, 2026. The 850 MW project is under construction near Drabshalla village in Kishtwar district of Jammu & Kashmir. The cofferdam was built to divert river flows and facilitate construction of the main concrete gravity dam.

Yamuna Manthan July 2026: River without Flows Even During Monsoon

It is well known that excessive diversion of Yamuna waters at the Hathnikund Barrage (HKB) in Yamuna Nagar, Haryana over the past two-and-a-half decades has turned the perennial river into a seasonal stream in its upper reaches during the lean season. However, an analysis of the Central Water Commission’s (CWC) hourly discharge figures and hydrographs since July 1, 2026 reveals that the river is now being deprived of its essential flows even during the monsoon.

This overview tracks the incidents of damage and threats to bridges and other river infrastructure across India between March 2023 and June 2026. The compilation shows that at least six bridge collapse incidents were reported where riverbed sand mining, sand transportation or excessive riverbed disturbance either directly contributed to the collapse or emerged as a significant risk factor alongside floods, poor construction and overloading.

Unscientific mining of riverbed minerals has emerged as a major geomorphic and disaster risk driver in Uttarakhand and Himachal Pradesh as per reports from past few years. Recent studies sharing examples of Ganga and Gaula rivers reveal broader pattern of how excessive riverbed extraction have been changing the very shape and behaviour of Himalayan rivers. The studies find that such mining is resulting in deepening of riverbeds, narrowing down of water channel thus disturbing the natural balance of riverbed minerals.
