The mega water reservoir of Tarbela has been filled to its maximum level of 1550 feet above mean sea level, resulting in 5.827 million acre feet (MAF) of water in the Dam, which is a good omen for agriculture and hydel power generation in Pakistan in the days to come.
Tarbela Dam is considered to be an iconic project for the contribution it has been making towards development of Pakistan since 1974 by releasing the stored water for agriculture, mitigating floods and providing low-cost hydel electricity to the National Grid. Tarbela Reservoir has a live water storage capacity of 5.826 MAF. Bedsides, Tarbela is the biggest electricity generation facility in Pakistan with installed capacity of 4888 megawatt (MW), which will further increase to 6418 MW after completion of Tarbela 5th Extension Hydropower Project.
