Tarbela Dam is an earth fill dam on the Indus River in Khyber Pakhtunkhwa in Pakistan. It's the largest earth-filled dam in the world and also the largest by structural volume. It is named after the town Tarbela, in Khyber Pakhtunkhwa, about 50 kilometres (31 mi) northwest of Islamabad, at Haripur District.
The dam is 485 feet (148 m) high above the riverbed. It forms the Tarbela Reservoir, with a surface area of approximately 250 square kilometres (97 sq mi). The dam was completed in 1976 and was designed to store water from the Indus River for irrigation, flood control, and the generation of hydroelectric power.
Its primary use is electricity generation. The installed capacity of the 3,478 MW Tarbela hydroelectric power stations will increase to 6,298MW after completion of the ongoing fourth extension and the planned fifth extension financed by Asian Infrastructure Investment Bank and the World Bank.
The project is at a narrow spot in the Indus River valley, at Tarbela between Haripur District and Swabi District, approximately 60 kilometers northwest of Islamabad.
