The project located at a narrow spot in the Indus river valley, at Tarbela in Haripur, shortly located at the point from where the district Swabi starts. The main wall of the build of earth and rock fill, stretches 2,743 meters(8,999ft) from the island to river right, standing 148 meters(486ft)high.

A hydroelectric power plant an the right side of the main dam houses 14 generators fed with water from out let tunnels 1, 2 and 3. There are four 175MW generators on tunnel 1, six 175MW. Generators on tunnel 2, and four 432 MW generator on tunnel 3, for a total generating capicity of 3,478MW.there are two main Indus river tributaries upstream of the Tarbela dam these are the Shyok river, joining near Skardu and the Siron river near near Tarbela. The Tarbela Dam is the third largest in term of Dam volume in the world.

Tarbela dam project resulted from a water treaty guaranteed Pakistan supplies independent of upstream control by India. Turquoise water of the Indus river reflect the high proportion of silt and clay suspended in water released by the spillways.The Tarbela dam is the largest earth and rock fill dam in the world.

there have been environmental consequences to the Indus river delta, Reduction of seasoned flloding and reduced water flows the delta have decreased mangrove stand and the abundance of some fish species.
