Sutlej Swells to High Flood as Indus Barrages Find Breather: A Tale of Two Rivers

A dramatic hydrological divergence is unfolding across Pakistan's vital river systems, presenting a mixed bag of relief and heightened alarm. While the colossal Indus River and its barrages are finally experiencing a welcome decline in water levels, offering a sigh of relief to communities along its banks, the Sutlej River is surging with alarming speed, threatening to unleash high-level floods in a critical turn of events.

The latest reports indicate a significant easing of the flood situation along the Indus.

Major barrages such as Taunsa, Chashma, Guddu, Sukkur, and Kotri are reporting flows that are either receding or have settled into 'low flood' categories. For instance, Taunsa recorded an inflow of 125,565 cusecs and an outflow of 123,565 cusecs, comfortably below the medium flood threshold. Similarly, Chashma, which was a point of concern, noted an inflow of 150,580 cusecs and an outflow of 145,580 cusecs, still within medium flood parameters but trending downwards.

Downstream, Guddu, Sukkur, and Kotri barrages are all reporting 'low flood' conditions, signaling a significant improvement and reducing the immediate threat to agricultural lands and settlements.

However, this reprieve is sharply contrasted by the escalating crisis on the Sutlej River. The river, particularly at Ganda Singh Wala, witnessed a rapid and perilous increase in water levels.

On Friday morning, flows were already at a 'medium flood' level of 95,000 cusecs. By evening, this figure had tragically soared to 120,000 cusecs, pushing the river into a 'high flood' category. This alarming surge is a direct consequence of massive water releases from India's Bhakra Dam and Pong Dam, with all 30 gates of the Harike Barrage reportedly opened to discharge an astounding 180,000 cusecs downstream.

Forecasters anticipate that the impact of these releases will soon be felt downstream.

Head Sulemanki is expected to reach 'medium to high flood' levels by Saturday morning, while Head Islam is bracing for 'medium flood' conditions. The Provincial Disaster Management Authority (PDMA) has swiftly issued a critical flood warning, urging extreme vigilance and preparedness for several districts lying in the path of the Sutlej’s fury.

These include Kasur, Okara, Pakpattan, Bahawalnagar, Vehari, Lodhran, and Bahawalpur, all of which are now under a significant threat of inundation.

Despite the developing situation on the Sutlej, the Panjnad, where the five major rivers of Punjab converge, is currently managing a 'low flood' situation, with inflows recorded at 112,504 cusecs and outflows at 102,504 cusecs.

This offers a momentary respite but remains a closely monitored point as the downstream impact of the Sutlej's surge propagates.

Authorities are urging residents in the vulnerable areas along the Sutlej to take immediate precautions, stay informed through official channels, and be prepared for potential evacuations.

This tale of two rivers underscores the complex and ever-present challenges of water management in the region, where a respite in one area can quickly be overshadowed by a looming crisis in another, demanding continuous monitoring and rapid response from disaster management agencies.
