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.

Despite sustaining cities with water supply, groundwater recharge, flood moderation, biodiversity, livelihoods and cultural services, India’s urban rivers continue to deteriorate, as highlighted by several reports this week. The Yamuna in Delhi remains the starkest example – ecologically dead across long stretches due to unchecked sewage inflows, shrinking flows and relentless floodplain encroachment. Similar stories are unfolding across the country, with Mumbai’s Mithi, Hyderabad’s Musi, Chennai’s Cooum, Bengaluru’s Vrishabhavathi, Ahmedabad’s Sabarmati, Vadodara’s Vishwamitri, Jaipur’s Dravyawati, Nasik’s Godvarai, Pune’s Mula-Mutha amd several other urban rivers increasingly reduced to sewage drains or heavily degraded waterways.

DRP 20 July 2026: Wither Dam Safety Compliance in India?

July 20, 2026 SANDRPLeave a comment

(Featue Image: A CDO team in May 2025 inspects the Srisailam Dam to assess its structural safety. Souce: TNIE)

It’s been five years since the Parliament passed the Dam Safety Act and the institutions including National and State Dam Safety committees and authorities were set up. However, how safe are our dams and how far have we achieved the Dam Safety Compliance norms? The answer to that question is unlikely to be confidence inspiring. This feeling is reinforced with a number of reports in recent weeks.

Riparian Forest 22 degrees Celsius cooler than the Riverfront Project!

July 16, 2026July 17, 2026 SANDRPLeave a comment

Pune saw some of the warmest summer days and nights this summer. So did several Indian cities. With the recent monsoon, the thoughts of this heat might have washed away but it is important that one does not forget the summer heat. Why? Read More:

Why run and hurry? Here’s dictionary: Microclimate: Microclimate generally refers to the specific climatic conditions within a small area (such as street, park, riverside, etc.). With rise in extreme events like heat and global warming, microclimate is what make cities/ spaces livable. The temperature difference you experience while driving on a road with no tree cover vs with a tree cover is what microclimate is.

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.

Rivers are the most important eco-systems, providing numerous economic, environmental social and cultural benefits. And in answer to the question, who governs India’s Rivers, we are generally likely to get response blank stares. Same is the likely response about the state of India’s rivers, who monitors our Rivers and so on.

“The sun was so hot, we knew the floods would be coming.” Says Jagdish ji, resident of Lindur village in the Lahaul Himalayas.

His home and fields are adjacent to a glacial stream called Jahlma Nallah which shoots from the Pir Panjal range to meet the Chenab River below. And just as he predicted, on the afternoon of 29th June 2026, like the past five years[1], Jahlma Nallah flooded and roared. In a matter of minutes, the thin flow transformed into a terrifying, brown debris-laden force. The sludge raced towards Chenab and nearly blocked the river by the brute force of water and debris it collected on its way. It cut off the connectivity of hundreds of villages.[2]

DRP 060726: India needs to improve Rainfall Monitoring?

Two reports from Karnataka this week highlight that over half of the 6605 rain gauges in Karnataka are non-functional. Earlier we saw that IMD does not even report rainfall for at least 11 districts in Arunachal Pradesh alone, possibly since it does not have adequate number of rain gauges in those newly formed districts of Arunachal Pradesh. IMD’s Annual Report for 2025 says P 59): “IMD operates 1,008 Automatic Weather Stations (AWS), 1,382 Automatic Rain Gauge (ARG) stations, 200 Agro-AWS, 5 Automatic Snow Gauge (ASG) stations”. That comes to 2395 locations where rain or snow is measured by IMD, going by the Annual Report. IMD apparently uses rainfall data from other agencies, but their number is not given in the report. IMD also has a large number of manual rain gauges, but the IMD Annual Report does not provide those numbers.
