Uttar Pradesh completes Ganga floodplain demarcation

Uttar Pradesh completed the physical demarcation of the 700-kilometre Ganga River floodplain zone across 13 districts from Unnao to Ballia. The boundary work was marked on the ground with 7,350 pillars, and the status was placed before the National Green Tribunal in August 2026.

Ganga floodplain zone

The floodplain zone of a river is the low-lying area adjacent to the river channel that can receive floodwater during high-flow periods. In the case of the Ganga in Uttar Pradesh, the demarcated stretch extends across a long river corridor and covers multiple administrative districts.

National Green Tribunal proceedings

The National Green Tribunal is a statutory environmental adjudicatory body established under the National Green Tribunal Act, 2010. The bench that took note of the completion included Chairperson Justice Prakash Shrivastava and expert member Afroz Ahmad. The Chief Engineer of the Uttar Pradesh Irrigation and Water Resource Department filed a status affidavit to confirm the completion of the boundary work.

Tributaries and encroachment control

The state report stated that floodplain zone delineation has also been completed for several Ganga tributaries, including the Yamuna, Ramganga, Betwa, Suvav, Tedhi, Budhi Ganga, Solani, and Khokhri. Demarcation remains in progress for the Kali, Varuna, Hindon, Pandu, and Noon rivers. Physical identification of floodplain boundaries is used for monitoring unauthorised construction and encroachment in river-adjacent areas.
