Water level in the reservoir during last two days increased by 16 feet and went up from 323.7 feet on Monday 339 feet on Tuesday night in the wake of current torrential rains being received in its 3,410 square miles catchment area which consists of Dadu district, Kirthar National Park, Saruna, Duraji, Shah Noorani area in Balochistan.
WAPDA CHIEF: Wapda’s chairman, Zulfiqar Ali Khan, who is scheduled to reach here in the wee hours of Wednesday will visit the dam on Wednesday to monitor the situation arising out of overflowing water from the dam’s spillway.
