Hirakud Dam is worked over the Mahanadi River, around 15 kilometers 9.3 mi from Sambalpur in the territory of Odisha in India. Behind the dam broadens a lake, Hirakud Reservoir, 55 km long. It is one of the principal major multipurpose stream valley ventures began after India's autonomy. In the upper seepage bowl of the Mahanadi River, fixated on the Chhattisgarh Plain, occasional dry spells stand out from the circumstance in the lower delta locale where surges may harm crops. The dam was built to help reduce these issues by making a store and controlling stream move through the waste framework. The dam controls the stream of the Mahanadi River and produces hydroelectricity through a few hydroelectric plants.
