ISLAMABAD (ANN/DAWN) – As per the advisory and warning from the Indus River System Authority, the Mangla Dam reached its dead level of 1,050 feet on Saturday, which could negatively affect agriculture in Sindh and Punjab because of an impending shortage of irrigation water.
On the other hand, Tarbela Dam also seems set to touch its dead level of 1,402 feet soon, as it recorded a storage level of 1,405.10 on Saturday. The water conservation level in Chashma Reservoir is also about to hit its dead level of 638.15 feet from the current 639.20 feet.
“Look, the water is life for all of us. Therefore, without it, we cannot live,” Pakistan Kissan Ittehad’s Chairman Khalid Khokhar told Dawn. “At present, the water flowing in the canal is less than the standard one, which leads to less watering for the crops—wheat, sugarcane, and others in the fields.”
According to Mian Ihsan Ul Haq, Pakistan Cotton Ginners Forum Chairman, the impact of water scarcity in Sindh may be more severe than in Punjab, as almost the entire agricultural land there relies on canal water.
“The underground water in Sindh has brackish water. This is why the farmers have no option but to use canal water for watering crops. So if there is less or no canal water in Sindh, all standing crops, including sugarcane, cannot survive in coming days,” he warned.
Mr Haq said the situation in Punjab, especially the southern parts, might also encounter a real threat. He said the Punjab government had already prohibited the preparation of sowing of the rice crop before May in the south Punjab.
To a question, he said if conditions do not improve, the crops, including wheat — which is yet to have last watering — sugarcane, several vegetable crops in tunnel farming and mango orchards could be adversely affected.
Meanwhile, the Water and Power Development Authority (Wapda) says that the Tarbela Dam’s live storage on Saturday remained at 0.015 million acre-feet (MAF), and its maximum water conservation capacity is 1,550 feet. .
The storage level in Chashma Lake, which has a minimum operating level of 638.15 feet, was recorded as 639.20 feet. Since the lake’s maximum conservation capacity is 649 feet, its live storage is 0.015 MAF.
“The inflows and outflows of River Indus at Tarbela, Jinnah 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 6am,” reads a statement issued by Wapda.
In a recent letter to provinces, Irsa warned Punjab and Balochistan, especially to prepare for up to 35 per cent water shortages in the last leg of the current crop season while operating the reservoirs on run-of-the-river mode at or around dead levels.
The Irsa data for the first week of March revealed that Tarbela Dam only has 73,000 acre-feet of water storage. Mangla Dam had a live storage of 235,000 acre-feet, with its level at 1,088 feet, just 28 feet above its dead level of 1,060 feet.
The authority further informed the provinces that both Tarbela and Mangla reservoirs may hit their dead levels soon.
It had already anticipated the start of the Rabi season on Oct 2, 2024, when it estimated the storage reaching dead level in the first 10 days of March.
Though the dam’s water storage level reduction is a common occurrence, the wheat crop is now at a critical stage of its last watering and is expected to be prepared for harvest by the end of this month.
