Uttar Pradesh informed the National Green Tribunal (NGT) that physical demarcation of the 700-km Ganga floodplain from Unnao to Ballia has been completed across 13 districts.
A total of 7,350 pillars were installed to mark the floodplain zone and help prevent encroachments and unauthorised construction.
Floodplain delineation has also been completed for tributaries including the Yamuna, Ramganga, Betwa, Suvav, Tedhi, Budhi Ganga, Solani and Khokhri.
Delineation of the Gomti, Ghaghra and Rapti rivers is targeted for completion by March 31, 2027.
The work supports implementation of the River Ganga Authorities Order, 2016 and earlier NGT directions.
