2) Tarbela Dam
Tarbela Dam is an earth-filled dam along the Indus River in Pakistan’s Khyber Pakhtunkhwa province. It is the largest earth-filled dam in the world.
The dam is 143 meters (470 ft) high above the riverbed and its reservoir, Tarbela Lake, has a surface area of approximately 250 square kilometers (97 sq mi). It was completed in 1976 and was designed to utilize water from the Indus River for irrigation, flood control, and the generation of hydroelectric power. The dam is at a narrow spot in the Indus River valley it was named after the town of Tarbela in the Haripur District of Hazara Division, Pakistan. Five large tunnels were constructed as part of the outlet works. Hydroelectricity is generated from turbines in tunnels 1 through 3, while tunnels 4 and 5 were designed for irrigation use. The installed capacity of the 4,888 MW Tarbela hydroelectric power stations will increase to 6,298 MW after the completion of the planned fifth extension.
