    Nice article
    Tarbela Dam is the largest earth-filled dam in the world?

    It is located near the city of Swabi and 105 km northwest of Islamabad. This humongous dam was constructed on the River Indus. The primary purpose of the dam was to store water for irrigation and generation of electricity.

    The construction of the dam started in 1968 and ended in 1976. The dam was built 143 meters above the river belt, with a storage capacity of 11.1 MAF. The maximum elevation level of the dam is 1550 feet.
