This is the summary report of Highest Flood Levels (HFL) breach incidents which we could document from CWC’s flood monitoring website during South West Monsoon Season 2025. The monthly reports for HFL breach incident for July 2025, August 2025 and September 2025 can be seen by clicking the hyperlinks and the detailed final report can be seen here. SANDRP’s previous reports on the subject can be seen here: HFL breach incidents in 2018, 2019, 2020, 2021 (I), 2021 (II), 2022 (I), 2022 (II), 2023, and 2024.
River Basin Wise Summary for SW Monsoon Season 2025
While the total number of sites where HFL breach incidents have occurred during 4 month long South West Monsoon season between June-Sept. 2025 stands at 55, the actual number of HFL breach incidents happened at 59 as there are 4 sites where HFL was breached twice during these months. Also 1 site Hayuliang on Lohit river in Brahmaputra basin where HFL was attained on May31, 2025 is added in the final tally.
The 59 sites are comprised of 56 level monitoring and just 03 level forecast sites spread over 9 river basins. The maximum 32 of such incidents is more than the half have occurred in Ganga basin alone. This including 10 such incidents from Yamuna basin. After this 15 such incidents have taken place in Indus basin followed by 4 in Krishna, 2 each in Tapi & Godavari basins and 1 each in Brahmaputra, Barak, Mahi, Narmada basins.
