Mangla Dam is an earthfill type dam constructed on river Jhelum in 1967 as a part of Indus Basin Development Plan. It is a multipurpose Project designed to conserve and regulate the floodwater of the River Jhelum for irrigation purpose and power generation.

Due to deposition of silt during 34 years of its operation the gross capacity has reduced from 5.88 MAF to 4.82 MAF

Initially its life was estimated as 120 years but later on with the implementation of watershed management practices in catchment area, its expected life is now estimated as 170 years.

Project Cost Rs.6.587 Billion (US$ 1.473 Billion) Objectives Provision of irrigation water to replenish for the waters of three eastern rivers and produce electric power for industrial and domestic uses.
