The dam edge is about 21km of earthen dykes on the both left and right sides, closing the low saddles beyond the adjacent hills.

On each side of the hills two observation towers has been built, one tower named as “Gandhi Minar” and the second one is “Nehru Minar”. Both the observation towers represent breathtaking views of the lake.
The Hirakud Dam control floods in Mahanadi delta and irrigates 7,500,000 hectares of land and hydroelectricity is also generated. The Hirakud Dam regulates 83,400 km² (32,200 mi²) of Mahanadi’s drain water.
