The Mangla Dam ( Urdu :منگلا بند) dams the Jhelam to a large reservoir in Pakistan .
The dam was built in 1966/67 near the city of Mirpur in Asad Kashmir , about 100 km southeast of the capital Islamabad , and has been used since then mainly for irrigation and electricity generation. Its catchment area covers 33,425 km².
The dam of the dam is - measured by the volume of the dam - one of the largest on earth. There are also slightly different information from other sources for the figure of 65.379 million cubic meters given in the table: 65.651, 64.991 and 63.880 million m³. (This probably applies before the increase.) The main structure includes four individual dams with two flood reliefs and five penstocks .
The hydropower plant generates a total of 1400 MW of power with ten vertical Francis turbines . 1500 MW are being discussed for the final expansion. The technical systems come from the following manufacturers. The bottleneck power is determined by the machine transformers .

The capacity of the reservoir had decreased by approx. 20% by silting up in 1999. Therefore, the dam is currently being increased from 138 by 12 m to 150 m. As a result, the reservoir level can be raised and the volume increased by around 18%. The crown length is (probably) extended to 3400 m.
Around 40,000 people had to be resettled for the construction of the dam.
