The flood pressure has been on rise at Kotri Barrage on Friday after the river water receding at Guddu and Sukkur barrages. Indus flow has reached to 6,58,000 cusecs at Kotri. Director General Meteorological department Qamruz Zaman Chaudhry has said that an unprecedented flow of seven to nine Lac cusecs will pass through the Kotri Barrage within next two to three days. High tidal waves in the sea could aggravate the flood situation in downstream in Thatta, he further said.
