2025 Western Himalayan Floods: What can be done to reduce disastrous impacts?

Scary visuals and messages on social media  as also some of the pronouncements of the Supreme Court about Himachal Pradesh have shown that Western. Himalayan states have faced multiple flood disasters in the ongoing SW Monsoon 2025. Landscape of Himalayas is known to be vulnerable to landslides, mudslips, cloudbursts, flash-floods, GLOFs, erosion, seismicity and floods. While some floods are inevitable in the kind of climate prevailing here, how they become disasters is linked to the way we have treated the landscape, environment,  regulations, people and floods.

Dharali Disaster in Uttarakhand: Amplified by Human Causes

The frightening debris-laden flash flood disaster at Dharali town along Kheer Gad-Bhagirathi river just 20 km downstream of Gangotri at around 1.30 pm on Tuesday, Aug 5 has demolished over 40 buildings, with scores (68 as on Aug 13 as per the Dehradun-based State Emergency Operation Centre) of people, including nine army jawans, reported missing (the numbers could go up as per several geologists) and at least five dead. The ground zero is still largely inaccessible four days after the disaster. While the full details of what caused the disaster are still a bit uncertain, what is clear is that the warning signs were present, they were ignored and a number of human causes amplified the proportions of the disaster. The scene of the disaster was similar to what we saw in Chamoli in Feb 2021 when ice and debris laden stream destroyed two hydropower projects killed over a hundred people.

As geologists said, the disaster was waiting to happen, but our governance did not seem to know.

Frequent 2024 Floods in Bhagalpur-Bihar

Guest Article by: Dr. Ruchi Shree

In 2024, Bihar received 19 percent less rainfall than the normal rainfall and one of its districts named Bhagalpur even lesser with 29 percent. From 1 June to October 21, this district of South Bihar situated on the banks of the Ganga received merely 713.8 mm rain while the expectation was 1054.3 mm according to India Meteorological Department figures. It is the third consecutive year when Bihar has received lesser rainfall than expectation[i] and it is likely to worsen the water scenario in the coming years. On the other hand, Bihar faced severe flood this year and Bhagalpur was one of its worst affected districts due to a rise in the level of the Ganga. In a span of around 45 days i.e. from mid-August to end of September, Bhagalpur faced floods four times. This writing is based on my observation of three locations in Nathnagar block of Bhagalpur — two villages named Dildarpur and Biharipur and the Tilka Manjhi Bhagalpur University (TMBU) premise (administrative wing and Lalbagh Professors’ Colony). TMBU is quite close to Dildarpur village (situated on the Diyara land between Champa Nalla/River and river Ganga).

With the onset of south west monsoon 2023, Himachal Pradesh has witnessed multiple incidents of ‘cloud bursts’ leading to destruction in Solan, Shimla, Hamirpur and Kullu between June 24-25. The extreme rainfall and resultant flash flood spells have caused widespread destruction to farms, cowsheds, local roads, bridges, vehicles and other public infrastructural in these districts.

Uttarakhand 2023: Drona Sagar another Neglected Lake of Kashipur

Like Giri taal, the Drona Sagar (29.12’24 N & 78.58’15 E) is another lake in Kashipur town succumbing to official neglect. The circular water body is spread over about 3 hectare of land and is hardly 1.5 km away from Giri taal in south east direction.

In recent past, both the lakes were fed by a distributary canal originating from Tumria dam on Phika river in Ramganga basin. Presently the canal portion between these lakes has been replaced with giant RCC hume pipes and a RCC road has been laid over it. The inlet of the canal joining Drona Sagar has also been cemented.
