Middle courseEdit

After being joined by the Seonath, the river flows in an easterly direction through the remaining part of its journey. It is joined by the Jonk and Hasdeo rivers here before entering into Odisha after covering about half of its total length. Near the city of Sambalpur, it is dammed by the largest earthen dam in the world, the Hirakud Dam. A composite structure of the earth, concrete and masonry, the dam measures 24 kilometres (15 mi) including the Dykes. It spans two hills; the Lamdungri on the left and the Chandili Dunguri on the right. It also forms the biggest artificial lake in Asia, with a reservoir holding 743 square kilometres (287 sq mi) at full capacity, with a shoreline of over 640 kilometres (400 mi).[5]

After the formation of Chhattisgarh State, the major portion of Mahanadi basin now lies in Chhattisgarh. Presently, only 154 square kilometres (59 sq mi) basin area of Hasdeo River in Anuppur District lies in Madhya Pradesh.

Before the construction of the dam in 1953, the Mahanadi was about a mile wide at Sambalpur and carried massive amounts of silt, especially during the monsoon. Today, it is a rather tame river after the construction of the dam and is joined by the Ib, Ong, Tel and other minor streams. It then skirts the boundaries of the Baudh district and forces a tortuous way between ridges and ledges in a series of rapids until it reaches Dholpur,Odisha. The rapids end here and the river rolls towards the Eastern Ghats, forcing its way through them via the 64 kilometres (40 mi) long Satkosia Gorge. The Satakosia Gorge ends at Badamul of Nayagarh. Dense forests cover the hills flanking the river here. The river enters the Odisha plains at Naraj, about 11 kilometres (6.8 mi) from Cuttack, where it pours down between two hills that are a mile apart. A barrage has been constructed here to regulate the river's flow into Cuttack.[6]
