The Subarnarekha fell below its danger mark at Rajghat in Odisha's Balasore district on 4 September 2026, a day after peaking at Jaleswar.
The river was flowing at 9.75 metres against a danger mark of 10.36 metres.
About 40 gram panchayats in Balasore were affected, including 22 in Bhograi block and 15 in Baliapal.
Four ODRAF teams, four NDRF teams, 12 fire service teams and three medical teams were deployed.
The Subarnarekha is a 395 km east-flowing river shared by Jharkhand, Odisha and West Bengal.
The Subarnarekha rises on the Chhotanagpur plateau near Ranchi, drops over Hundru Falls as it leaves the plateau, passes Jamshedpur, is regulated by the Chandil Dam and Galudih Barrage, then crosses into Odisha's Balasore district - where Jaleswar, Bhograi and Baliapal sit on its lower floodplain - before reaching the Bay of Bengal near Kirtania.
