ISLAMABAD (APP) - After a comparatively long hold for floods, now Tarbela and Mangla dams have started to release water to fulfil the agricultural needs of the provinces and to boost the production of hydropower. Due to the floods in the country, this year both dams delayed water release to avoid further problems while last year they started an immediate discharge of water after getting filled, private news channel reported. Mangla on July 31 and Tarbela on August 23 were completely filled with water.
