LAHORE – The water level at the major reservoir Mangle Dam is fast approaching the maximum storage level due to significant monsoon rains in the upper parts of Pakistan.
The water level at Mangla Dam reached 1240.6 feet above mean sea level with live storage of 7.242 million acre-feet on Tuesday, just 1.4 feet below the maximum conservation level of 1242 feet.
The minimum operating level at Mangla Dam is 1050 feet.
Another major reservoir Tarbela Dam achieved a maximum conservation level of 1550 feet with live storage of 5.809 MAF on August 11 (last Friday).
As significant rains are expected in catchment areas, WAPDA released more water for hydel electricity generation during the last 2-3 days which caused a slight dip in water level at Tarbela Dam.
On Tuesday, the water level at Tarbela Dam reached 1549.04 feet as against a maximum conservation level of 1550 feet and minimum operating level of 1402.
Live storage at Tarbela Dam was 5.754 MAF.
The water level at Chashma reached 647 feet with live storage of 0.186 MAF as against the minimum operating level of 638.15 feet and maximum conservation level of 649 feet.
Filling of both Mangla and Tarbela dams to maximum storage capacity is a good omen for under stressed agriculture sector and low-cost hydel electricity generation.
