The Narmada Canal is a contour canal in Western India that brings water from the Sardar Sarovar Dam to the state of Gujarat and then into Rajasthan state. The main canal has a length of 532 kilometres (331 mi) (458 kilometres (285 mi) in Gujarat and then 74 kilometres (46 mi) in Rajasthan). It is the second longest canal in India (after the Indira Gandhi Canal) and the largest canal by water carrying capacity (40,000 cusec at source).[1] The main canal is connected with 42 branch canals providing irrigation to 2,129,000 hectares (5,260,000 acres) farmland (about 18 lakh hectares in Gujarat and 2.5 lakh hectares in Rajasthan).[1] The canal is designed to transfer 9.5 million acre-feet (11.7 cubic kilometres) water annually from the Narmada Basin to areas under other river basins in Gujarat and Rajasthan. (9 MAF for Gujarat and 0.5 MAF for Rajasthan).[2]
Soon after the completion of the construction project, the Narmada canal was inaugurated on 24 April 2008.[3] It has carrying capacity of 40,000 cubic foot per second (cfs or cusec) at its head in Navagam and is decreased to 2,600 cusecs at Sanchore. On the way, Narmada main canal crosses many rivers and water bodies. The main canal itself can hold 220 MCM (Million cubic metre) of water at full supply depth. It is designed not only for the water supply but also the storage of water to improve the response time of the system.[4]
