Hirakud Dam is located at a distance of 6 km from national high way no. 6. The nearest rail head is Hirakud Railway Station which is at a distance of 8 km from the dam site. Hirakud Dam Project is a multipurpose scheme intended for fllod control, irrigation and power generation. The dam is built across river Mahanandi at about 15 km upstream of Sambalpur town in the state of Odisha. This is one of the oldest hydel projects of India, being the first post-indenpendence major multi purpose river valley project in the country. In 1948 Pandit Jawaharlal Nehru laid the foundation stone.
The Project provides 1,55,635 hectares of Kharif and 1,08,385 hectares of Rabi irrigation in the districts of Sambalpur, Bargarh, Bolangir and Subarnapur. The water released through the power house irrigates further 4,36,000 hectares of C.C.A in Mahanandi Delta. The installed capacity for power grneration is 347.5 M.W through its two power houses at Burla, at the right bank and Chiplima, at 22 km down srream of Dam. The project provides flood protection to 9500 sq. km of delta area in districts of Cuttack and Puri.
After high floods of 1937, M.Viseswaraya gave proposal for detail investigation for storage reservoirs in Mahanandi basin to tackle problem of flood in Mahanandi delta. Hirakud Dam Project is the first stage of the plan of Dr. Ajodhya Nath Khosla, then Governor of Odisha. The commissioning of Unit 3 of Burla Power House was completed on 18-12-1956. The project was formally inaugurated by Pandit Jawaharlal Nehru on 13 th January 1957. The project cost is Rs. 100.02 crores.
On 15 March 1946, Sir Howthrone Lewis, the then Governer of Odisha, laid the foundation stone of the Hirakud Dam. A project report was submitted to the government in june 1947. Pandit Jawaharlal Nehru laid the first batch of concrerte on 12 th April 1948. The Dam was completed in 1953 and was formally inaugurated by Prime Minister Jawaharlal Nehru on 13 th January 1957. The total cost of project is 1000.2 millions in 1957. Power and irrigation started in 1956, achieving full potential in 1966.

The Dam supports two different hydroelectric power houses. power House one is located at the base of the main dam section and contains 3 x 37.5 MW Keplan turbine and 2 x 24 MW Francis turbine generators for an installed the capacity of 259.5 MW . 2 nd Power house is located 19 km south east of the dam at Chipilima. It contains 3 x 24 MW genarators. The entire instaled capacity of dam’s power houses is 307.5 MW.
