About Hirakud Dam:
- Hirakud Dam is built across the Mahanadi River, about 15 kilometres (9.3 mi) from Sambalpur in the state of Odisha in India.
- It is one of the first major multipurpose river valley projects started after India’s independence (1948-1957).
About Mahanadi River:
- The Mahanadi is a major river in East Central India.
- The river flows through the states of Chhattisgarh and Odisha.
- Like many other seasonal Indian rivers, the Mahanadi too is a combination of many mountain streams and thus its precise source is impossible to pinpoint.
- 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.
- After the formation of Chhattisgarh State, the major portion of Mahanadi basin now lies in Chhattisgarh.
- The Mahanadi was notorious for its devastating floods for much of recorded history.Thus it was called ‘the sorrow of Orissa’
