In major reservoirs Rains improve river flows, water level


ISLAMABAD: Recent rains have improved river flows, which have subsequently enhanced storage in major reservoirs of the country, and are likely to cause high to very high flood in the River Chenab at some major headworks, including Marala, Khanki and Qadirabad.

“According to latest hydrological conditions River Chenab at Marala, Khanki and Qadirabad is likely to attain high flood level in next 36 hours,” says a forecast issued by the Flood Forecasting Division (FFD) of the Pakistan Meteorological Department.

An official of the Indus River System Authority (Irsa) endorsed that the Marala, Khanki and Qadirabad might attain “very high flood (VHF)” level.

The designed capacity at these stations is about 1.1 million cusecs. When these stations attain 400,000-cusec level, the situation is described as VHF in terms of danger classification.

The two major reservoirs — Tarbela and Mangla — had achieved water levels 10.77 feet and 77.10 feet below their respective maximum conservation levels of 1,550 feet and 1,242 feet. The total combined live storage of the three reservoirs — Mangla, Tarbela and Chashma — was reported at 7.897 million acre feet (MAF), which is 57.72 per cent of the total storage capacity of 13.681MAF.
