The document summarizes information about the Mangla Dam located in Pakistan. It describes how the dam was constructed between 1961-1965 across the Jhelum River to strengthen Pakistan's irrigation system and reduce agricultural shortcomings. It cost Rs15.587 billion to build and displaced over 110,000 people. The dam initially had a reservoir capacity of 7.25 billion cubic meters but sedimentation reduced this. A raising project from 2004-2009 increased the dam height and storage capacity.

MANGLA DAM
• MANGLA DAM is a multipurpose dam situated on
the Jhelum River in the Mirpur District of Azad
Jammu and Kashmir, Pakistan.
• It is the seventh-largest dam in the world.
• In November 1961, it was announced that Binnie &
Partners, a British engineering firm, were going to
serve as the lead designers, engineers and
inspectors for construction of the dam
Introduction

3. • India gained rights to the waters of the Ravi, Sutlej,
and Beas rivers.
• While Pakistan received the rights to develop the
Jhelum, Chenab and Indus river basins
• The agricultural yield was very low for a number of
reasons, the most significant being a lack of water
during critical growing periods.
• This Dam was the first of the two dams constructed
to reduce this shortcoming and strengthen the
irrigation system of the country, other is Tarbela
Dam Swabi, KPK.

Displacement &
Resettlement
• The Government of Pakistan had agreed to pay
royalties to the Government of AJK (Azad Jammu and
Kashmir) for the use of the water and electricity
generated by the dam.
• Over 280 villages and the towns of Mirpur and Dadyal
were submerged and over 110,000 people were
displaced from the area as a result of the dam being
built.
• There are 747,000 Mirpuris in the United Kingdom
and there are 70% of the Mirpuris are present in the
British Pakistani community.

6. • Mangla reservoir had an initial reservoir capacity of
7.25 billion cubic meters (5.88 million acre-feet),
which reduced to 5.77 billion cubic meters(4.674
million acre-ft) in 2005 due to the sedimentation.
• Mangla Dam Raising Project was started in 2004
and the main dam, spillway, and its allied works
were completed in 2009 at a cost of Rs. 101.384
billion.
• This project effectively raised:
- Dam height by 30 feet to 482 feet (147 m),
- water conservation level from 1202 feet to
1242 feet.

7. • This increased the dam's storage capacity from 5.56 to
9.12 billion m3 (4.51 to 7.39 million acre-ft).
• after raising the height of the Mangla Dam by 30 feet,
the powerhouse will generate 12 percent additional
energy per year which will increase its installed capacity
from 1,000 MW to 1,120 MW.
• The Mangla Dam Raising Project, however, has affected
more than 40,000 people. The total cost of
compensation and resettlement was Rs. 70 billion.
• The resettlement project includes the construction of
- New Mirpur City,
- Four satellite towns,
- The Mirpur Bypass and
- Two bridges across River Jehlum and Bong Canal.

8. • In November 2012, United States announced a
grant of $150 million for the expansion of the
Mangla Dam powerhouse. Under the project, $400
million would be spent on the Mangla Dam
powerhouse which is estimated to provide
additional production for the next 40 years.
• After completion, It will increase the power
generation capacity of the Mangla Dam to 1,310
MW from the existing 1000 MW capacity.

• The dam was further expanded in the era of Pervez
Musharraf but it did not enhance the capacity of
electric generation except increasing the level of
water in the dam.
