Tarbela Dam (Pashto: د توربېلې بند, Hindko: تربیلا بند) is an earth-filled dam along the Indus River in Pakistan's Khyber Pakhtunkhwa province. It is located mainly in the |Haripur Tehsil Ghazi
[1] It is about 20 km (10 mi) from the city of Swabi KPK, 105 km (65 mi) northwest of Islamabad, and 125 km (80 mi) east of Peshawar. It is the largest earth-filled dam in the world.[2][3][4] The dam is 143 metres (470 ft) high above the riverbed and its reservoir, Tarbela Lake, has a surface area of approximately 250 square kilometres (97 sq mi).[citation needed]
The Tarbela Dam is located on the Indus River near the village of Tarbela in Bara, approximately 30 kilometers from the town of Attock. Positioned where the Indus River emerges from the foothills of the Himalayas and enters the Potwar Plateau, the dam features a reservoir for water storage. The average annual flow available is 101 billion cubic meters (3221 m3/sec).[5] It stands 143 meters tall and covers an area of 243 square kilometers. It has a storage capacity of 11.9 billion cubic meters of water and has nine gates to control the outflow of water. The dam was completed in 1976 and was designed to utilize water from the Indus River for irrigation, flood control, and the generation of hydroelectric power[6] by storing flows during the monsoon period while subsequently releasing stored water during the low flow period in winter. The installed capacity of the 4,888 MW Tarbela hydroelectric power stations will increase to 6,418 MW after completion of the planned fifth extension financed by Asian Infrastructure Investment Bank and the World Bank. Then, it will be the 12th largest hydroelectric dam in the world, for electricity production capacity. [7]
