Sardar Sarovar Dam has been built over the Narmada river in Gujarat. This is one of the largest water resources projects of India covering four states – Maharashtra, Madhya Pradesh, Gujarat and Rajasthan. The Sardar Sarovar Project would meet the requirement of water in drought prone and desert areas. Sardar Sarovar Project will provide irrigation facilities to 18.45 lakh hectare of land, covering 3112 villages in 15 districts of Gujarat. It will also irrigate 2,46,000 hectare of land in the strategic desert districts of Barmer and Jalore in Rajasthan and 37,500 hectare in the tribal hilly tract of Maharashtra through lift. About 75% of the command area in Gujarat is drought prone while entire command in Rajasthan is drought prone. Assured water supply will soon make this area drought proof.
