ISLAMABAD - The country’s major water reservoir Tarbela dam is likely to achieve its maximum level of 1550 feet within next 48 hours, while there is no chance of filling of Mangla reservoir to its maximum level during current season.

Tarbela is currently at 1547.20 feet and most likely it will reach its peak level by August 18 or 19, official of the Indus River System Authority (IRSA) told The Nation. It is worth mentioning here that last year Tarbela reached its peak level during the first week of September, for very little period, however this time the maximum level will be attained approximately two weeks earlier. Tarbela attaining its peak level would mean that the country will have enough water for the upcoming Rabi season starting from October 1st. However, the official said that Mangla dam will not fill to its peak level of 1242 feet during current season. Mangla dam level is currently more than 70 feet short of the peak level. On Tuesday, the total inflows in the rivers were 534600 cusecs, while total outflows were 484900 cusecs, while the total live storage was 8.457 MAF

Inflows in river Indus at Tarbela were 284300  cusecs against the outflows of 269300 cusecs, inflows in Kabul at Nowshera 47300 cusecs and outflows 47300 cusecs, inflows in Jhelum at Mangla were 44700 cusecs and outflows 10000 cusecs, inflows in Chenab at Marala were 155900 cusecs and outflows 143500 cusecs.
