The irrigation and flood control department of Delhi has proposed revisions to the Yamuna River's flood warning and danger marks due to increasing siltation at its base. Officials suggest raising the warning mark from 204.5 meters to 205 meters and the danger mark from 205.33 meters to 205.75 meters. This adjustment aims to provide a more accurate gauge for warning and evacuating residents in vulnerable low-lying areas. The current levels have been deemed inadequate as they do not reflect the river's altered base levels, which have changed due to years of silt buildup and insufficient dredging. The highest recorded water level of 208.66 meters on July 13, 2023, resulted in significant flooding, surpassing the previous record of 207.49 meters set in 1978. Activists have criticized the government's flood management strategies, citing failures in forecasting and the impact of encroachments on the floodplain. They argue that simply changing the flood markers is insufficient without addressing the underlying issues of siltation and urban encroachment. The final decision on the proposed changes will rest with the Delhi government.
