On Thursday, Resident Engineer Mangla, in a letter to Chief Engineer (Hydel Operation) intimated that Mangla reservoir has approached dead level ie 1050 feet Survey of Pakistan Datum (SPD) at 3 pm.
He further stated that in order to maintain the level at 1050ft SPD (dead level) as per instructions received from Chief Engineer (Operations) Wapda, inflows and outflows have been equalized. The letter further states that presently one unit is on bar at 30MW with a discharge of 2200 CFs (cusec feet) through Mangla power station.
According to Wapda, discharge of 1280 CFs is being carried out through Jari valve (with max. permissible opening) in line with Irsa directives. Irsa spokesperson, Rana Khlalid said that after detailed discussions at an emergent meeting presided over by Chairman Irsa, Sher Zaman Khan on Mangla dam's position, Irsa has decided to open Chashma-Jhelum Link Canal with immediate effect with a discharge of 4000 cusecs to save Trimmu-Sindhnai barrages.
The decision was taken by a 3 to 1 majority vote, as Member Sindh strongly objected to opening of Chashma-Jhelum Link Canal.
