The Mahanadi is an important river in the state of Odisha. This river flows slowly for about 900 kilometres (560 mi) and deposits more silt than any other river in the Indian subcontinent.
The cities of Cuttack and Sambalpur were prominent trading places in the ancient world and the river itself has been referred to as the Manada in Ptolemy's works. However today the Mahanadi valley is best known for its fertile soil and flourishing agriculture. Prior to the Hirakud dacarthe Indian subcontinent.
Floods
The Mahanadi was notorious for its devastating floods for much of recorded history. Thus it was called 'the sorrow of Orissa'. However the construction of the Hirakud Dam has greatly altered the situation. Today a network of canals, barrages and check dams keep the river well in control. However heavy rain can still cause large scale flooding as evidenced in September, 2008 when 16 people died as the river breached its banks.
In 2011, September heavy down pour of rain caused flash flood and many mud dwellings in more than 25 villages above Hirakud Dam which were never affected before, both in Chhattisgarh and Odisha, have melted down due to back water that could not pass through the river.
