Tarbela Dam attains maximum storage capacity

Lahore: In what can be termed as a significant development for water storage in the country, Tarbela Dam today filled to its maximum water conservation level i.e. 1550 feet above mean sea level. Consequently, the water reservoir attained its maximum live storage capacity of 6.45 million acre feet (MAF).

According to the details, the position of the river inflows and outflows at Tarbela, Mangla and Chashma along with the reservoirs levels and the barrages today is as under:

Rivers: Indus at Tarbela-Inflows 114,800 cusecs and Outflows 114,300 cusecs, Kabul at Nowshera: Inflows 24,700 cusecs and Outflows 24,700 cusecs, Jhelum at Mangla- Inflows 21,700 cusecs and Outflows 10,000 cusecs, Chenab at Marala- Inflows 47,200 cusecs and Outflows 15,300 cusecs.

Barrages: Jinnah-Inflows 145,000 cusecs and Outflows 136,700 cusecs, Chashma -Inflows 165,700 cusecs and Outflows 190,000 cusecs, Taunsa- Inflows 225,600 cusecs and Outflows 197,700 cusecs, Panjnad- Inflows 23,800 cusecs and Outflows 8,200, Guddu- Inflows 189,000 cusecs and Outflows 161,200 cusecs, Sukkur- Inflows 142,700 cusecs and Outflows 87,700 cusecs, Kotri- Inflows 56,742 cusecs and Outflows 17,057 cusecs.

Reservoirs’ Level and Storage: Tarbela – dead level 1380 feet, present level 1550 feet, maximum level 1550 feet, live storage 6.450 million acre feet (MAF) Mangla – dead level 1040 feet, present level 1233.10 feet, maximum level 1242 feet, live storage 6.694 MAF, Chashma – dead level 637 feet, present level 644.00 feet, maximum level 649 feet, live storage 0.115 MAF.

The inflows and outflows of River Indus at Tarbela and Chashma, River Kabul at Nowshera and River Jhelum at Mangla have been reflected as mean flows of 24 hours, whereas the other flows have been gauged at 6.00 a.m.
