The Indus River System Authority (IRSA) has decided in consultation with the provinces to close canals from December 26 to January 31 for annual maintenance and de-silting.
The plan will reduce the output of hydropower units of Terbella and Mangla by more than 2,000 MW, resulting in increased loadshedding amid extreme winter across the country.
The official sources informed Pakistan Today that IRSA has notified the annual canal closure plan, under which canals would remain closed from December 26 to January 31 for maintenance and de-silting. They said that the canals of Mangla would be closed from December 26 till January 31 in stage wise, and canals of Terbella would remain closed from January 10 to January 31. According to the water discharge plan, the authority will release 10,000 to 12,000 cusecs of water from Tarbela Dam and 8,000 cusecs from Mangla Dam to meet drinking water requirements, they added.
