In Oct. 2025, we could find at least 06 flood monitoring sites of Central Water Commission (CWC), where rivers have crossed their Highest Flood Levels (HFL) after the end of South West Monsoon season 2025 on Sept 30 2025. Of the 6 sites, 2 each are in Brahmaputra basin in W Bengal and Ganga basin in Bihar. 1 site Anantharam on Musi river in Telangana is part of Krishna basin and 1 site Marella on Gundlakamma river in Andhra Pradesh is part of East Flowing Rivers between Mahandi and Pennar basin.

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.

Hydropower-GLOF Nexus in Chenab Headwaters: Absence of credible studies and accountable governance
Increasing incidences of Glacial Lake Outburst Floods (GLOFs) are being experienced in the Indian Himalayas. One of the most notable examples of GLOF was the Chorabari Lake GLOF that occurred on 16th June 2013 in Kedarnath, Uttarakhand[1] which was triggered by heavy rainfall induced mass movements into the lake. The GLOF devastated villages of Kedarnath, Rambara, and Gaurikund. Around 6,000 people were officially killed, and a significant number of the deaths were linked to the GLOF. Countless bridges and roads were washed away, and about thirty hydropower plants were affected or completely devastated. Several Hydropower projects resulted in exponential losses to life and livelihoods. Whole of Uttarakhand was affected in the disaster, and a significant proportion of it was related with GLOF.
