Mahanadi Riveris one of the principal east-flowing interstate river systems in peninsular India. It rises near the village of Farsiya, close to Nagri in Dhamtari district, Chhattisgarh, at a height of approximately 442 metres above mean sea level and merges with the Bay of Bengal after travelling for about 851 km. The river basin drains roughly 1,41,600 sq. State in Chhattisgarh and Odisha, with fringes in Jharkhand, Maharashtra and Madhya Pradesh. The Mahanadi is one of the few river systems in India that has a large drainage network, fertile delta and main tributaries, and enormous importance for irrigation, hydropower and water resources.<\/span><\/p>\n

Mahanadi River System<\/span><\/h2>\n

The Mahanadi River System is an interstate river basin in east central India, also a major part of the water resources of India. It originates in the Chhattisgarh highlands and runs east across plains into a delta and the Bay of Bengal. Millions of people who reside in its basin are supported through the water for agriculture, industries, drinking purposes, fisheries, and hydropower generation. The river is also noted for major irrigation works, including the Hirakud Dam, reputedly one of the longest earthen dams in the world. The Mahanadi is an integral part of the socio-economic development in eastern India and has a wide drainage network with many tributaries.<\/span><\/p>\n

Mahanadi River System Tributaries<\/span><\/h2>\n

The <\/span>Mahanadi River System<\/b> is fed by numerous tributaries originating from the <\/span>Satpura, Maikal, Eastern Ghats, and Chhota Nagpur Plateau<\/b> regions. These tributaries significantly enhance the river’s flow and support irrigation, agriculture, and water supply across central and eastern India.<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n
