Mangla Dam on the river Jhelum was constructed in which year?

The construction of the Mangla Dam, a vital multi-purpose dam on the Jhelum River in Pakistan, commenced in 1962. This massive project was undertaken as part of the Indus Waters Treaty to manage water resources for irrigation and power generation. While the dam was completed and inaugurated in 1967, the question specifically asks for the year construction began. Therefore, 1962 is the correct answer, marking the initiation of this significant engineering feat. Options 1966, 1999, and 2000 are incorrect as they fall outside the period of the dam's initial construction phase.
