In July 2025 during the South West Monsoon, we have found rivers crossing their respective Highest Flood Levels (HFL) at least at 12 flood monitoring sites of Central Water Commission (CWC). Of the 12 sites, 11 are in Ganga basin and 1 site is in Narmada basin. The details of all these sites are given in table below. The sixth column of the table is the information about rise in meter (m) over the old HFL, duration (hours-hrs) the river has stayed in extreme floods and number of years (yrs) after the HFL is breached. The 12 sites are spread over 5 states: Madhya Pradesh, Uttar Pradesh, Bihar, Uttarakhand and Jharkhand.

A Glacial Lake Outburst Flood (GLOF) disaster in Lehende Khola river impacted several hydro-electric power (HEP) projects in Nepal on July 8, 2025. The deadly flood occurred around 3 am in Rasuwa and Nuwakot districts of Nepal bordering Tibet region under China control. As a result, the water level in Lehende river rose by 3.5 meters in Timure, Rasuwa. The merging of Kerung and Lehende rivers in Tibet forms the Bhotekoshi river in Nepal and it is part of Trishuli sub-basin under Narayani river system.

CWC, IMD Need to Improve Extreme Weather Forecast Services

May 17, 2025 SANDRPLeave a comment

The rising numbers and intensity of western disturbances (WDs) in pre-monsoon months are causing excessive but short rainfall spells across the country particularly in the Himalayan states. These events are then resulting in sudden flash floods and taking a huge toll on human life and public infrastructure. However, the specific monitoring and warning services for such disasters by the Central Water Commission (CWC) & Indian Meteorological Department (IMD) are largely unavailable as these agencies are mainly forecasting floods during the monsoon.

Imprudent management of SSP and other Narmada dams could create avoidable flood disaster in Sept 2024?

September 11, 2024September 11, 2024 SANDRPLeave a comment

Similar to we wrote on Sept 1 2024 [i], but possibly with even greater flood prospects and urgency, the situation in Narmada River Basin is once again moving towards a massive avoidable flood disaster due to imprudent management of Sardar Sarovar dam in Gujarat and dams including Indira Sagar, Omkareshwar, Bargi and Tawa dams in Madhya Pradesh. All of these dams are full or almost full with IMD Flash Flood Bulletin (FFB, bulletin is updated thrice a day) as at 0730 hrs on Sept 11 2024 [ii] warning about the ongoing or imminent flash flood in Narmada Valley districts.

The cloudburst induced flashflood destruction took place late on July 25, 2024 in Palchan area of Manali tehsil in Kullu district. Many of the media reports have also mentioned about the deluge damaging a hydroelectric power (HEP) project in Palchan just in a single line without revealing any details or even the name of the HEP.

While looking for more information about the affected HEP, we came to know that not just one but two HEPs have faced significant damages due to the flashflood incident. Both projects are owned and run by private companies in upper Beas River basin.
