Explanation:

 The Nathpa Jhakri Dam is a concrete gravity dam on the Satluj River in Himachal Pradesh, India. A Memorandum of Understanding for execution of the Nathpa-Jhakri project was signed between Government of India and Government of Himachal Pradesh in July, 1991. Construction on the project began in 1993; the original plan called for a five-year construction period, but a rockslide shortly after the civil contract was signed in 1993 required extensive stabilisation work, and the project had to be redesigned. The project was finally commissioned in May 2004 and officially dedicated to the nation by Prime Minister Manmohan Singh on May 28, 2005.
