IRSA writes letter to hydel operation chief engineer

ISLAMABAD: The Indus River System Authority (IRSA) has stopped water releases from Mangla after the reservoir’s level reached the dead level.

According to the letter to hydel operation chief engineer by Mangla Resident Engineer, the water level at the Mangla reservoir has reached the dead level as per the recent data of Survey of Pakistan Datum (SPD).

In order to maintain the level of 1050ft the inflows and outflows have been equalised, the letter further states. Presently one unit is on bars at 30 MW with a discharge of 2200 (cusec feet) CFs through Mangla power station.

According to Wapda, discharge of 1280 CFs is being made through Jari valve (with max. permissible opening) in line with IRSA directives.


IRSA spokesperson Rana Khlalid said after detailed discussions at first meeting presided 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 3.1 majority vote, as Member Sindh strongly objected on opening of Chashma-Jhelum Link Canal.
