Sardar Sarovar Dam usually has no water for irrigation during summers. However, for the first time in history, the dam has been filled with Narmada water.
About Sardar Sarovar Dam:
- Sardar Sarovar Narmada Dam is a terminal dam built on the Narmada river at Kevadia in Gujarat’s Narmada district. The dam is called the ‘lifeline of Gujarat’.
- Indian States: The four Indian states namely Gujarat, Madhya Pradesh, Maharashtra and Rajasthan receive water and electricity supply from the dam. They share the water as per the ratio stipulated by the 1979 award of the Narmada Water Dispute Tribunal.
- Construction of the Dam:
- The foundation stone of the dam was laid out by Prime Minister Jawaharlal Nehru in 1961.
- However, the construction of the dam was stopped by the Supreme Court of India in 1995 over concerns of displacement of people.
- In 2000–01, the project was again revived but with a lower height under directions from SC. But its height was later again increased to 139 metres in 2017.
- The dam was then inaugurated in 2017 by the present Prime minister.
Water Management Initiatives that helped to harness water for the Dam:
- During the monsoon, the Sardar Sarovar Dam operation is well synchronised with the rain forecast in the catchment area. The government ensures minimum water flows downstream into the sea and maximum water is used during the dam overflow period. This help in maximizing the annual allocation of a water share.
- However, in the non-monsoon months, the measures for efficient use of the allocated water share typically includes:
- Minimising the conventional and operational losses.
- Avoiding water wastage
- Restricting water-intensive perennial crops
- Adoption of Underground Pipelines(UGPL);
- Proper maintenance of canals and structures and
- Operation of canals on a rotational basis.
