THE MANGLA DAM     The world’s largest dam at the time of its

completion.

     Total fill was 140 million cubic yards. (in all the four dams, main dam, Jari dam, intake dam and Sukian dam.)

     Previous largest dam was “fort peck dam” on the Missouri river in Usa.

PRIMARY FUNCTION

To increase the amount of water that could be used for irrigation

To generate electrical power from the irrigation releases at the artificial head of the reservoir

STRUCTURES Main Structures Of The Mangla Dam Include

4 Embankment Dams

2 Spillways

5 Irrigation Tunnels

A Power Station

GENERAL INFORMATION     50 million dollar earth moving machinery “world’s

largest peace time collection of construction equipment.”

     Average rate of fill was 3 million cubic yard per month.

     With max. Rate 4 million cubic yard per month.

17

GENERAL INFORMATION

     Aggregate plant capacity 3000 cubic yards of concrete per hour. world’s biggest plant at that time.

     “Mole” to drive tunnels, specially designed. 36 ft. diameter to excavate 1650 ft. long five tunnels. at a rate 105 ft. per day. operated by “Pakistani” operators.

EFFECTIVESOver 280 villages and the towns of Mirpur and Dadyal

were submerged

Over 110,000 people were displaced from the area

People had to leave their ancestral homes
