Bansagar or Ban Sagar Dam is a multipurpose Rriver Valley Project on Son River situated in Ganga Basin in Madhya Pradesh, India envisaging both irrigation and hydroelectric power generation.
The Bansagar Dam across Sone River has been constructed at village Deolond in Shahdol district on Rewa-Shahdol road, at a distance of 51.4 km from Rewa. The project has been named as "Bansagar" after Bana Bhatt, the renowned Sanskrit scholar of 7th century, who is believed to have hailed from this region in India. Bansagar Dam is located at Latitude 24-11-30 N and Longitude 81-17-15 E.
The project was initially envisaged as "Dimba Project" in 1956 by Central Water Commission, New Delhi to be constructed on Sone River at the confluence of Sone and Banas River near Shikarganj town 30 km down the present site. Later it was shifted to the present site at Deolond.
There was an agreement in 1973 between the State Governments of Madhya Pradesh, Uttar Pradesh and Bihar for the construction of the Dam, according to which States had to share the expenditure in the ratio of 2:1:1. The sharing of 4 maf water is also to be done by the states in the same ratio. The construction work was started in year 1978 at original approved cost of Rs. 91.31 crores. The latest estimated cost in 1998 was Rs. 1054.96 crores.
The objective to build this dam was to enhance both irrigation and hydroelectric power generation.
The project has been named as "Bansagar" after the renowned Sanskrit scholar of 7th century - Bana Bhatt. Bansagar Dam co ordinates the Latitude of 24-11-30 N and Longitude 81-17-15 E.
The primary benefit of the Bansagar Dam is related to the irrigational purposes. The water sharing from Bansagar Dam is as under Madhya Pradesh, Uttar Pradesh and Bihar.
Bansagar dam provides irrigation facility over an area of 2,490 km² in Madhya Pradesh, 1,500 km² and in Uttar Pradesh and 940 km² in Bihar.
The Bansagar Dam was dedicated to nation on 25 September 2006 by Atal Bihari Vajpayee, former Prime Minister of India. The foundation of ambitious Bansagar project was laid by Late Prime Minister Morarji Desai on 14 May 1978. The Bansagar Canal Project started in 1978 and completed in 2008. The Canal Systems, which are under construction to utilize water from the Bansagar Reservoir, shall be started shortly.
