2. The history of Mangla Dam
• As part of the Indus Waters Treaty signed in 1960, India gained
rights to the waters of the Ravi, Sutlej and Beas rivers, while
Pakistan, in addition to waters of the above three rivers within
Pakistan and some monetary compensation received the rights to
develop the Jhelum, Chenab and Indus river basins through
construction of the Indus Basin Project.
• Until 1967, the entire irrigation system of Pakistan was fully
dependent on unregulated flows of the Indus and its major
tributaries.
• The agricultural yield was very low for a number of reasons, the
most important being a lack of water during critical growing periods.

3. The Mangla Dam Project
• Mangla Dam is the sixteenth largest dam in the world.
• It was constructed from 1961 to 1967 across the Jhelum River, about 67
miles (108 km) south-east of the Pakistani capital, Islamabad in Mirpur
District of Azad Kashmir, Pakistan.
• The main structures of the dam include 4 embankment dams, 2 spillways,
5 power-cum-irrigation tunnels and a 1,000 MW power station.

4. The Project Designed
• The project was designed primarily to increase the amount of water
that could be used for irrigation from the flow of the Jhelum and its
tributaries.
• Its secondary function was to generate electrical power from the
irrigation releases at the artificial head of the reservoir.
• The project was not designed as a flood control structure, although
some benefit in this respect also arises from its use for irrigation and
water supply.
• The Government of Pakistan had agreed to pay royalties to the
Government of AJK

5. Mangla Dam Raising
Since its first impounding in 1967, sedimentation has occurred to the extent of 1.13
MAF, and the present gross storage capacity has declined to 4.75 MAF from the actual
design of 5.88 MAF.
The live capacity has declined to 4.58 MAF from 5.34 MAF.
This implies a reduction of 19.22% in the capacity of the dam.
