Бхагиратхи
The Bhagirathi River splits the Murshidabad district into two natural physiographic regions – Rarh on the west and Bagri on the east. The Lalbag subdivision is spread over both Bagri and Rarh physiographic regions from the Jalangi-Bhagirathi Interfluve to the Ganges-Bhagirathi basin to the Nabagram plains.
