River basin wise cumulative rains during the season in Yamuna basin have been in large excess category in Ghambir and Chambal sub basin of the river, in excess category in upper, middle and lower segment of river. The Sind, Betwa and Ken river sub basin have also witnessed rains in excess category during this period and Upper Chambal and Kunwari basin have recorded rains in normal category. Notably, the IMD provided different cumulative normal rainfall figures for all the basins in Yamuna river catchment in 2024 as mentioned in this report. Also the IMD has not provided cumulative rainfall figures for Tons, Giri, Asan and Hindon sub-basins.
Overall, the upper Yamuna basin have received excess category rains in monsoon season 2025. The river also witnessed significant flows all through August 2025 and three flood spells (medium, low and high flood events) in a span of two weeks between August 17 and Sept. 1, 2025 reviving the river throughout its most polluted segment.
Flood: However, out of 4 months the rain and flood impact was evident only for one and half months of August and Sept. 2025. It appears that the operation of Ichari and Vyasi dams in Himalayan segment influenced the natural flooding pattern of the river as covered in this report. Besides, the Sept. 2025 flood spell in the river has again caused unusual impacts in Delhi as highlighted in this report. Additionally, the encroachments of floodplain, opaque operation barrages, riverbed mining and siltation have appeared altering the flood carrying capacity of the river in Delhi and downstream areas as underlined in this report.
HFL Breach: There have been breach of Highest Flood Levels (HFL) in Yamuna basin during 2025 monsoon at least at 11 flood monitoring sites of CWC of which 6 are on main stem of Yamuna and the 5 on its tributaries in lower segment. Except the Kuthnaur site on Yamuna river, the remaining 5 sites are located downstream Delhi and all had attained HFL in July 2023. The details of HFL breach are given in table below.

Finally, despite good rainfall in upper basin, the river has hardly been getting even the 5 percent of the available inflows from Hathni Kund Barrage since the beginning of the November 2025. The increase in water diversion, pollution and riverbed mining operations in upper segment after the season have largely been undoing the rainfall and flood impacts. It is remained to be seen if the rains in winter and pre monsoon months would be able to provide some respite to the river. Otherwise, river will return to and remain in flowless and highly polluted state in upper segment during the lean season ahead.
