MAHANANDA RIVER

(GEOGRAPHY)

1. Mahananda River

The Mahananda River is an important trans-boundary tributary of the Ganga. It flows through the Indian states of West Bengal and Bihar before entering Bangladesh. Originating in the Darjeeling Hills of the Eastern Himalayas, it supports agriculture, biodiversity, and local livelihoods across the Indo-Bangladesh river basin region.

2. Origin – Paglajhora Falls

The Mahananda River originates from Paglajhora Falls on Mahaldiram Hill near Chimli, east of Kurseong in Darjeeling district, West Bengal. The source lies at an elevation of about 2,100 meters (6,900 feet) above sea level. Its Himalayan origin provides a perennial water supply throughout much of the year.

3. Course of the Mahananda River

From its Himalayan source, the Mahananda flows southward through the plains of North Bengal and Bihar. It then enters Bangladesh and eventually rejoins India before meeting the Ganga. The river acts as an important drainage channel and supports fertile agricultural lands along its course.

4. Balason River

The Balason River is a major tributary of the Mahananda River. Originating in the Darjeeling Hills, it carries significant runoff from mountainous regions. The river contributes water and sediment to the Mahananda system and plays an important role in irrigation, ecology, and regional water resources management.

5. Mechi River

The Mechi River is an important tributary of the Mahananda River and forms part of the boundary between India and Nepal in certain stretches. Originating in the Himalayas, it contributes to the river basin's hydrology and supports agriculture, settlements, and biodiversity in the border region.
