He said Chief Engineers of Lahore, Faisalabad, Sargodha, Multan, Dera Ghazi Khan and Bahawalpur irrigation zones have been advised to send water needs of their respective canal networks so that the Indus River System Authority (IRSA) could be asked to release additional water from the reservoirs out of Punjab's share of water for Kharif crops from 1st April to 30th September 2011.
The six monthly non-perennial canals were closed in the last week of October 2010 after reduction in river flows on setting in of winter season. However perennial canals continued to flow except for month long desilting in December - January.
